Planetary Art

I enjoy creating art on a computer and with real paint.  

Below are some fanciful exoplanets I painted recently.

An exoplanet is a planet that is outside our solar system.  No one has seen a real exoplanet yet, but I have some guesses about how some of them look.


I made some mistakes on this one, but it's ok.  I fixed them later.


I painted these on poster boards.  You don't have to spend a lot of money on canvases.


These planets orbit near a black hole.


These planets are hanging on my wall in my basement.

I also post art and other space topics here: https://www.facebook.com/RamoneRocketeer

Black Hole Art

From NASA...

A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. Matter and radiation fall in, but they can’t get out.

Two main classes of black holes have been extensively observed. Stellar-mass black holes with three to dozens of times the Sun’s mass are spread throughout our Milky Way galaxy, while supermassive monsters weighing 100,000 to billions of solar masses are found in the centers of most big galaxies, ours included.

What if an ion-drive probe could visit an unnamed gas giant orbiting near a black hole?  It might look like this.
