Below are some of my dabblings into the world science fiction themed art. Click on the previews for a full size image you can download for personal use. Comments and discussions are always welcome. (email@example.com) Enjoy!
Stellar Systems of Orion
The Orion constellation is one of the most distinctive constellations in the sky and is visible from both the Northern and Southern Hemispheres. Its outline is made up of some of the brightest blue-giant stars in the night sky with Rigel leading the group marking Orion's right leg. Betelgeuse, a red super-giant marks Orion's left shoulder. Orion has many other treasures and the stars we see, Rigel, Mintaka (the belt star on the right), Alnitak (the belt star on the left), are not just single stars but are made up of multiple stars orbiting each other. The image below shows these star system, plus an additional one, Sigma Orionis, which is below Alnitak. And, let's not forget about the Orion Nebula, a veritable star factory containing over 3000 stars! (Check out the blog post about these star system.)
In a game of cosmic billiards a comet threads its way between a planet and one of its moons. We were not as lucky on June 30, 1908 when an asteroid exploded over Tunguska, Russia, leveling trees over 830 square miles (2,150 sq. km). International Asteroid day is celebrated on June 30th to bring attention to the threat asteroids pose to our world.
The top image shows a very active comet shrouded in a gaseous coma and generating a blue ion tail along with it's dust tail, while the image on the bottom shows a less active comet nucleus shedding dust, more akin to the comet 67P/Churyumov–Gerasimenko that ESA's Rosetta mission spent two years studying.
I’m fascinated with the idea of convergent evolution, where different species can independently evolve the same features over different times or epochs. Extending this to habitable exoplanets makes me wonder if a land-bound species would develop the same technology to sail their seas that we developed on Earth. Is this development driven strictly by the laws of physics? I would expect that those species that gained a deeper understanding of math and the sciences would more rapidly develop the technology to travel to the stars after sailing their oceans. Just one more thing to ponder when you gaze up at the night sky...
In the Beginning
A rocky planet going through its early stages of evolution as observed from the vantage point of one of its moons, which is also going though the throes of early development. The moon, being smaller than the planet is cooling more quickly and has a thickening crust, which is fractured with numerous volcanoes and rifts.
A habitable planet in a trinary star system whose inhabitants have felt the wrath of Mother Nature while sailing its seas. Too often we think of extraterrestrials as more advanced than we are, but we may find that is not the case as we venture out in the cosmos.
Ice and Water
Exoplanets are sounding more and more appealing with the current state of affairs on our planet Earth. Here's a nice one with some sun, some water, a little bit of ice (Maybe more than a little bit!) and even some fauna flying and swimming through its ecosystems. We just have to find it...and then find a way to get there!
Above the Clouds
Back out in the cosmos and cruising through the clouds with some local fauna of a habitable moon of a gas giant. Maybe one day humankind will see something like this firsthand.
Meanwhile, back on Earth in the Northern Hemisphere it is autumn:
Autumn Morning Colors
A Really Bad Day!
A rogue planet with its accompanying moon slamming into Earth is not something one wants to contemplate, but it's a possible, although not very probable. We have more to worry about from asteroids that are in our solar system or passing through. Some of these are small enough to miss detection, and they can come from any direction. And, they can be large enough to destroy a city...a very big city!
Appreciate all that we have today, as we do not know what tomorrow will bring!
Orion in 3D Revisited (Featured in Astronomy Picture of the Day)
A revised 3D plot of the Orion constellation, based on a new reduction of the Hipparcos data set by F. van Leeuwen, pushes Orion's stars around a bit from an earlier graph I did in 2014.
The new data set pushes Orion's middle belt star, Alnilam, out past the nebula, which makes the star much brighter and larger than previously thought. In fact, it now is the brightest star in absolute magnitude in the constellation! See the blog post: Orion in 3D Revisited for more information.
If we were to take all the stars of Orion and move them to a distance of 10 parsecs (32.6 light years) from Earth, (The distance used to determine the absolute magnitude for a star.) the constellation would be visible during the daytime! Below is an approximation of what that might look like around noontime. (At night it would be amazing!!)
With over 6 billion potentially habitable planets in our galaxy alone (not to mention any moon that may be habitable), one has to wonder why we have not had contact with ETs. Could be that the speed of light barrier doesn't allow us to conquer the vast distances between the stars, or maybe we are the smartest bunch on the block and everyone else is technologically behind us. Or there is no one else...
"Sail On" depicts a planet where the population is using sails to explore their world.
Dusty Mars from Phobos
Time to get off planet Earth and back into space!
A probe from Earth lands on Mars' largest moon, Phobos, just in time to see a dust storm envelop the red planet. Mars' smaller, more distant moon, Deimos, can be seen of in the distance on the left.
Meanwhile, still back on Earth:
Meanwhile back on Earth:
At the outer fringes of the habitable zone in a binary star system a snow-covered moon orbits a ringed planet. Despite the frozen environment the moon is teaming with life. The skiing is great! Swimming - not so much!
Orion in 3D
Orion the Hunter is one of the most recognizable constellations in the night sky, and one of its striking characteristics is the red super-giant star, Betelgeuse, that marks his left shoulder. This star is a variable star that changes in brightness over time, but as of the fall of 2019 it has been steadily dimming. As of February 2020 it has set a new record with its new luminosity and lower temperature. This may be a prelude to the star going supernova, but then again maybe not. Astronomers think that it could be a 100,000 years or more before that will happen. But, then again, there is a lot we don't know about the Cosmos and we are learning more each day. Maybe Betelgeuse will teach us a thing or two! (For more information on Orion and the 3D perspective in the illustration, check out the blog post: The Multidimensional Constellation, Orion.)
Volcanos, destroyers and builders of worlds. They can shape the geography of a planet with the lava they exude and influence its atmosphere by the gas, ash and other particulates they pump out. This image shows an exoplanet on the outskirts of a galaxy in the neighborhood of a globular cluster. A series of volcanic islands are forming due to plate tectonic, similar to the Hawaiian island chain in the Pacific. Thermal vents may exist in the depths of the oceans nurturing more advanced life...
Autumn Stream and Winter Stream Christmas Night
Two terrestrial images to enjoy and celebrate the beauty of our planet Earth:
Winter Stream Christmas Night
As of mid-September 2019 there were just over 4050 confirmed exoplanets. A small percentage of those are the right size, in the right orbit around their stars to have liquid water available and may potentially have environments that could harbor life as we know it. Extrapolating our small sample of stars and the planets that orbit them to the Milky Way Galaxy at large, there may be hundreds of billions of exoplanets out there, with billions in the habitable zones of stars. But it doesn't stop there, because if we consider that many of these planets may have moons, which may also have the right properties to support support life as we know it, the number of habitable celestial bodies could be in the hundreds of billions. What about life as we don't know it?
With all those planets out there we have a lot of exploring to do! In “Night Expedition” a group of future space explorers examine a newly discovered moon orbiting a ringed gas giant.
Somewhere out there among the estimated 40 billion Earth-sized planets and potentially trillions of moons orbiting in habitable zones of stars, a local star is setting on distant shores of an exo-moon orbiting a gas giant in a binary system.
Sunny With Scattered Snow Showers
Some exoplanets will have weather just as we have on Earth. Some of those will have a dynamic biosphere filled with life reminiscent of our home world. With over 4000 exoplanets confirmed, as of July 2019, who knows what wonders await us!
Exomoon Annular Eclipse
An annular eclipse is where the foreground planet doesn’t fully block the disk of the star, leaving a ring of light visible around it. In the image there is a binary system consisting of a standard G-type yellow dwarf star similar to our sun and a red dwarf. The yellow dwarf has a planetary system which contains a habitable exomoon that orbits a gas giant at just the right distance so that it’s populace is treated to an eclipse with every orbit.
The Mars rover, Opportunity, spent 15 years traversing the surface of Mars, covering 28 miles (45 km) while looking for evidence of water. Eventually humans will walk the surface of the red planet and in time they will look for those intrepid machines that preceded them. “Opportunity Found” depicts a Martian evening and the first time human eyes directly behold the rover since it left Earth.
The Moon rising fully immersed in the Earth's shadow during a total eclipse.
End game: Twin gravity tractors shepherd a rogue asteroid that was on a collision course with Earth. The asteroid did not present a global threat per se, but it is large enough to destroy a large city such as New York, London or Moscow.
The gravity tractors will exert a steady gravitational pull on the asteroid, shifting its trajectory and given adequate time, the asteroid can be deflected enough to miss the Earth. Either of the tractors by itself could deflect the asteroid, but two were sent in the event that if one were to fail, the mission could still be completed. Planetary defense using gravity tractors will only be successful if we find the asteroid threat early enough.
Lunar Christmas 2018
A cold, clear winter night with a comet and meteor accompanying the full moon in lighting up the forest at night.
Aurora on Exoplanet #9
Earth is not the only planet in our solar system that is illuminated by auroras, the gas giants and ice giants in the outer solar system also have auroral displays. Even Mars and Venus have auroras, although driven by a different process. So if we have them, then they must also be found throughout the cosmos and 'Aurora on Exoplanet #9' is one imagining of such a planet.
It's autumn in the Northern Hemisphere and here's a tribute to the beauty Mother Nature paints across our landscape.
Before ET started zipping around the universe using their hyper-drive, warp-drive, jump-drive, starburst, hyper-space, wormholes, and/or FTL (faster than light) engines, they probably first climbed out of their local gravity well using chemical rockets just as we do today. (That is assuming that the ACME - Really Big Rubber Band didn't work for them either!)
“First Launch” depicts the inhabitants of a moon orbiting a ringed planet setting off on their first journey into space.
The Milky Way galaxy has about 300 billion stars, and with the latest data gathered from Kepler and other sources there is the potential that most of these stars have at least one planet (probably more) orbiting them, and some of these planets may be in the habitable zone. And, if you consider the possibility that these planets may have moons, some of which may be habitable, then there are a whole lot of places out there for life to evolve. (Remember, this is just one galaxy out of hundreds of billions of galaxies in our observable universe.) Now consider multiverses...an infinite number of other universes that may co-exist with ours.
"Parallel Universe" illustrates a habitable moon of a gas giant in a binary star system somewhere out there, with some very familiar architecture...
3700 confirmed exoplanets and several thousand more potential
candidates located in a small part of our galaxy, I can't believe
there is not life out there somewhere. "Distant Shores" is
a glimpse of one possible exoplanet with a variety of life
inhabiting it that parallels the beautiful planet we
Dinner for Two with a View
Mainly from a refusal to believe that we are destined to be sequestered forever in this backwater of the galaxy, and the confidence I have that we will someday find a way to conquer the immense distances between the stars, I offer “Dinner for Two with a View”. A gas giant, in the habitable zone of a star, dances with many moons, one of which is a water-world paradise of sorts and makes the perfect vacation destination. Make your reservations soon! Oh, and don’t drink the water!
Sooner or later we will have people on the Moon and they may find that their electronic link to the home world does not satisfy their visceral need to connect with the Earth. A lone astronaut journeys through shades of greys, blacks and whites to take in the view of our home planet with its swirls of white over the blues, browns and greens.
We have a moon, but imagine if we had rings! Of course, if we did, we would be as lackadaisical about the rings as we are about our moon. But here, in "Ringworld", somewhere in this vast cosmos, a family takes in the view of a ringworld in what was once a trinary star system. Long ago, one of its stars went supernova and left behind a stellar-mass black hole that now feeds off its closest companion and blasts jets of high energy particles and X-rays into the surrounding galaxy. What a view!
Meanwhile, back on Earth. Enjoy the sun rising and flirting with the crescent moon over the Atlantic Ocean to start a new day!Primordial
Life started in the seas. Water provided the medium and all the nutrients needed for life to form from simple single-celled lifeforms to multi-cellular plants and eventually animals. But, perhaps it didn't evolve spontaneously. Perhaps it was seeded by comets, asteroids and meteors from other habitable planets. This is known as panspermia and the theory is supported in part by the meteors we find on Earth that are directly traceable to Mars. Who knows what pieces of Earth we may find on Mars.
Primordial Sunset was chosen for the back cover illustration for the Planetary Society's Planetary Report magazine December Solstice 2018 issue.
Ice fairies come out to mark the winter solstice, the day the sun is at its lowest altitude at noon in the Northern Hemisphere bringing the shortest day of the year. Ironically, the Earth is closest to the sun at this time of year (the closest point or perihelion will occur on January 3, 2018), but the tilt of planet causes the Northern Hemisphere to experience shorter days and less direct sunlight ushering in winter in the north and conversely, summer in the Southern Hemisphere.
Life undoubtedly exists or has exited or will exist on other planets scattered about our galaxy and beyond. These beings will explore their planet and eventually look to the stars to satisfy their wanderlust. In the image "Journey to the Setting Moons" we see a ship leaving the harbor and in "Homeward Bound" we see the ship returning to its home port half a world away.
Inspired by the 'dream tree' in the wonderful movie "The BFG" (The Big Friendly Giant, by Roald Dahl) "Ring Tree" combines the magic of an aurora with a shimmering fog and rising ringed planet.
Rings are probably more common in the cosmos than one might expect. Some are bold, dramatic rings like the ones encircling Saturn, while others are wispy, barely visible rings like the ones around Jupiter, Uranus and Neptune. In fact it was recently discovered that a small (1,218 miles long (1,960 km)), potato-shaped dwarf planet, Haumea, has a ring and two small moons.
Bridge to a Galaxy Far - Morning
A follow-up to "Bridge to a Galaxy Far": Morning comes with the rising of the parent gas giant and sister moon as the nearby galaxy that dominated the night sky sets.
Globular clusters orbit around the center of a galaxy, (Our Milky Way Galaxy has about 150 of them.) and in this image the inhabitants of a planet in one cluster have the pleasure of seeing their parent galaxy rise in all it's glory every night. As they watch the galaxy rise, there's more than one set of eyes in the galaxy admiring the globular cluster rising in their night sky.
Night in the Cluster
Back to the globular cluster for a night on the shore
under the celestial fireworks. A night sky filled with
bright orbs of light that would hamper the deep-sky
observations we enjoy on our planet. Imagine the
reaction of inhabitants of such a planet suddenly finding
themselves on Earth, with its single moon and the Milky Way
A binary star system with one star similar to our sun and the other a red supergiant. Bloated and blowing off layers of star-stuff for the last million years, the super giant is now moments away from exploding in one of nature’s most spectacular events - a type II supernova. The indigenous population is oblivious to the cataclysm that is about to obliterate their home world.
Orion on Watch
For thousands of years these massive structures have stood by and silently watched mankind swim in the river of time. We see them today as ghostly remnants of the white marble-clad structures that they once were. It must have been awe-inspiring to see them under construction and even more so to see the finished pyramids.
"Orion on Watch" depicts a cool desert night, with the constellation Orion hanging overhead and Mars, Jupiter and Saturn joining the mix as the second great pyramid is being constructed.
A distant waterless world with a spiral galaxy gracing its night sky. Galaxy created and unwittingly contributed by one cdmodelbuilding88 (AKA C.C. Davison) - thanks!
On the edge of the "Goldilocks Zone", the zone where liquid water can exist and potentially support life as we know it, a planet's moon supports advanced life amongst the abundant snow and ice. Night will soon be filled with with a setting mother planet and sister moons.
Hollywood has introduced us to many extraterrestrials, most of them hell-bent on either eating us or conquering and enslaving us. But, what will first contact really be like. What will they look like? What will they smell like? How will they talk and communicate with us? Will this contact be amicable or deadly? So many questions and none of them will be answered until that very first moment we discover that we are not alone in the cosmos. "Contact" depicts our first literal contact with an alien species.
A ringed planet with a habitable moon, where life has evolved to appreciate the simple natural beauty of water flowing over a precipice. It will be very interesting to find out if other evolved species located on distant planets in the cosmos share our fascination with waterfalls.
Some...most pictures start out with a concept in mind and end up very differently from what I had imagined they would look like. Eagle Falls is no exception. It was more an exercise in trying to create a waterfall that looks somewhat realistic. I've already got a concept for the next image which will include water falls. But who knows where it will end up! Enjoy Eagle Falls Sunset with a special appearance by the Moon, Venus and Mercury, and the daytime version of Eagle Falls.Cassini's Garden
commemoration of the amazing probe, mission and team of people
that put Cassini in orbit about Saturn and collected data for over
The current thinking today is that almost every star may have a planet or planets orbiting it, and with planets you're going to have moons. All this increases the opportunities for extraterrestrial life to evolve. This is amazing in its own right, but even more amazing to me is that these beings will have followed the same steps we have: first, explore their lands, then journey across their seas, and once they conquered the world they evolved on, they would look to the stars...
The Universe presents an almost infinite pallet from which to create life. Who's to say that there are not entities out there with the power to play with planets for amusement? I present for your contemplation, "Playthings".
Have they been here already? Have they added to their collection one by one and we've not noticed? Are they out there at all? Maybe one day we'll find out, until then, enjoy!
A habitable moon orbiting a ringed gas giant on the distant outskirts of a dazzling globular cluster - what a sight it would make in the night sky!
What would it look like to live on a planet orbiting a star inside a globular cluster? This image tries to show what such a planet might have as a night sky. Located some distance from the center of the cluster off to the right of the image, the sky is full of stars that provide enough light to easily read by. Deeper into the cluster the night sky would be even brighter.
An abstract representation of life on planet Earth in the 21st century. Let us all hope the storm abates soon...
Planets in the habitable zone around a star may have water on their surface in the form of liquid, ice or just water vapor. The planet in the image is mostly dry and arid except for occasional monsoon rains that leave behind temporary pools, which could potentially provide an oasis for life as long as the water is present. This life may be nothing more than simple bacteria or possibly more advanced lifeforms that have evolved to cope with the fleeting presence of life-giving water.
Twilight, that magical time when day melts into night and colors flow across the sky with abandon. The picture was based on an amazing sunset I saw a few months ago which left me in awe of Mother Nature and angry that I didn't have a camera to capture the moment.
"Twilight" is set on a planet not unlike our own, but it's really one of two moons orbiting a larger planet with a glorious galaxy floating in the background. Sit back, relax and enjoy!
We live in a simple solar system consisting of one star and at least 8 planets, depending on your definition of planet. The majority of stars not in the category of red dwarfs, exist in a binary system, two stars orbiting a common center of mass. There are also solar systems consisting of three, four or more stars, which makes for a very interesting environment if you happen to live on a planet in one of these multi-star systems. "Night" would take on a totally different meaning from what we know it to be -- if it were ever defined at all.
Enjoy Starry Night and think about living on a planet with endless daylight, and the wonders of the Universe we would never know about all for the lack of a night sky...
Sunset at Wellesly Island
Meanwhile, back on Earth, in the Thousand Islands on the St. Lawrence River to be exact, the Sun is setting. No alien creatures, no binary stars or multiple moons, just a simple, beautiful sunset over the Lake of the Isles that is surrounded by Wellesly Island on the US side and Hill Island on the Canadian side. A beautiful place to visit if you ever have the opportunity.
Life - Not as We Know It
What's out there? Probably not bipedal, humanoid life with wrinkled foreheads, spotted faces and knobby noses so frequently depicted in modern sci-fi today. What may be out there is probably more bizarre than we can imagine. Take a look at what swims in our seas! (And, this is just what we know about.)
Below are two versions of the same scene depicting life on a watery planet, which exists near a sparkling globular cluster and nebula giving birth new stars. The two versions are basically the same scene but with very different atmospheres and consequentially very different lighting effects. I put both up for your viewing pleasure because I couldn't make up my mind which version I liked better! Let me know which one you prefer.
Extraterrestrials, as portrayed by popular media, typically either want to eat our brains or strip the natural resources from our planet. But, what if we are the technologically advanced civilization visiting a world that is just starting to be explored by its natives. Will we be intelligent or civilized enough not to interfere with the planet's inhabitants natural development?
Journey Far depicts explorers on distant planet leaving the shelter of their harbors and homes to discover the wonders their planet holds in store for them.
The eclipses we experience on Earth are due to the periodic alignment of our Sun, Moon and planet. We will have two solar eclipses in 2015: a total eclipse on March 20th, and a partial eclipse on September 13th. Since solar eclipses are followed shortly thereafter by lunar eclipses, there will also be two lunar eclipses in 2015: April 4th and September 28th.
Imagine the number of eclipses a planet with more than one moon (Jupiter and Saturn have over 50 moons each!) and/or in a binary or trinary star system would have! The image below shows a gas giant system with a number of moons, some of which have their own moons. Multiple eclipses are in process; can you find all five of them?
The current estimate of potentially habitable planets in the Milky Way galaxy is on the order of tens of billions - we aren't even considering the moons that might be orbiting these planets, and may have water and atmospheres conducive for life. Planet Rise shows a gas giant rising over an ocean teaming with life on one of its moons.
Take a ride through a wormhole! Theoretically, wormholes exist, but we've not seen one - yet. Then again, there's a lot out there in the Universe we haven't seen, but we are only starting to look. Who knows what we're going to find once we step beyond the bounds of our solar system.
Desert Oasis - Night and Morning
Two new wallpapers - same place, different times. I couldn't make up my mind which one I liked best so I'll leave the choice up to you!
Who knows what may be found on a planet in the habitable zone around a not too distant star. Blue sky, blue water, a temple paying homage to the local star that provides the energy for life on this planet. A place we could call home. It's out there--somewhere, waiting for us to find it...
Inspiration for my pictures comes from so many
different places. Blue Heron came one day in March when I
was attending an art exhibit of a very dear friend and AMAZING
Rhinevault. Tatiana had done this beautiful painting
of a blue heron wading in a small backwater on the Hudson
River. Tatiana's Blue
Heron just pulled me in and I had to see if I
could duplicate this wonderful image using Vue and GIMP.
After many, many hours, with countless tweaks, adjustments and
renders I finally realized that I would not be able to replicate
Tatiana's artistic interpretation of this beautiful nature
scene. My end result is below. If you follow the
link above you can see Tatiana's painting to compare. I
highly recommend you take a look at her website and enjoy the
amazing skill and depth Tatiana has. Unfortunately, the
pictures of her paintings do not do justice to the
originals. They need to be seen in person. Take a
few minutes and check out her site.
been with us since early man formed the first stone
tools. We tend to forget that as we journey through our
days with our cell phones, tablets, GPS and Internet--the
state-of-the-art. But, state-of-the-art is transitory,
and tomorrow's technology will make today's look
years ago, the ancient Egyptians were perfecting their
state-of-the-art in the construction of buildings we marvel at
today. The precision and scope of what they did on the
Giza Plateau with the Great Pyramid of Khufu amaze us today
with all of our modern science and technology. But, the
Egyptians developed their technology by first building mounds
for burial chambers, followed by single level structures --
mestabas, which evolved into multi-level structures known as
step pyramids, the Pyramid
of Djoser is a great example, and the pinnacle of their
achievements, the classic pyramids we see at Giza.
The image below celebrates that evolution, the intellect and the ingenuity of this ancient civilization.
the current estimate that one out of every five stars in our
Milky Way galaxy has an Earth-like planet in the habitable
zone, we may be looking at a minimum of
about 500 million planets in the galaxy that might harbor life
of some sort. This number is probably easily an order of
magnitude higher or more if we consider planets on the fringe
of the habitable zones and their moons.
Exile is about one poor sole in one such system that has been banished to a cold, wintery world where he can see his home planet rise every night -- not the large lifeless moon, but the distant pale blue dot, flanked by its two moons.
Change of Season
It's not too hard to imagine an extraterrestrial planet in some distant star system, with the right geological evolution and astronomical orientation, that its inhabitants have built their own version of Stonehenge to mark the change of seasons.
Are we the only creatures on this amazing planet that can appreciate the beauty of a full Moon floating above the horizon? This thought was the seed for this wallpaper of a pod of orcas pausing to take in the view. Sophisticated animals, with complex societies and language, killer whales may just be able to appreciate the world around them. Maybe someday we will be able share their thoughts on a rising Moon.
An early wallpaper,
working with Vue Esprit for the first time and combining alien
themes with one of my favorite topics - ancient Egypt.
Inspired by the majestic, mystical tree in the movie, "The Fountain". The movie has many amazing images, especially toward the end as they approach the Orion Nebula.
Earth's first probe to a planet in the habitable zone of a distant star, finds a moon that is Earth-like in many respects. But, this temple, built in homage to the ringed gas-giant that graces its skies, is all that remains of a long extinct civilization of that moon. We were too late...
the Past to the Future
The meeting of two icons of science fiction literature are here in this mash-up of Verne and Clark. Both men were visionaries of the capabilities of humankind.
Globular clusters are amazing spherical collections of old generation stars, like mini galaxies, which can contain hundreds of thousands of stars. It would be an amazing sight to visit a planet that was near enough to a cluster to see it dominate the night sky like a perpetual firework!
