Detail of a digital painting depicting the landing of European space probe Huygens on Saturn's moon Titan in 2005

Seven Digital Space Art Paintings

Space art as a genre is older than you might think. As early as 1301, a certain Giotto di Bondone from Florence made a painting depicting Halley’s comet. But the big breakthrough didn’t come until the late 1800s, when science fiction writers like Jules Verne and H.G. Wells started writing books that needed to be illustrated. Space art pioneers like Chesley Bonestell, Pat Rawlings and Don Dixon used the tools available to them in their days: paint, charcoal, chalk, pencil. Today, space artists, not to mention filmmakers, use digital tools with which nothing is impossible. Miles long spaceships on which… Read More

Is There Really No Planet B?

It’s a popular theme in science fiction: the quest for a new Earth, because the old one is becoming uninhabitable, usually due to human interventions. The search, in other words, for planet B, a place to escape the self-inflicted crisis. Sometimes the idea is elaborated in a somewhat ironic manner, like in the unsurpassed Dutch series Missie Aarde (Mission Earth), in which the Netherlands take the lead because it’s the only country not under water thanks to its dykes. Sometimes it’s dead serious, as in the movie Interstellar, in which drought, dust storms and crop failures make the need for… Read More

Impressionist sketch of a fictional abbey on the dark side of one of the planets around the ultra cool dwarf star TRAPPIST-1

TRAPPIST-1: the Link between Astronomy and Beer

Today we will travel to 2MASS J23062928-0502285, better known as TRAPPIST-1, a star at about 40.5 light years from Earth. That would normally be quite a long journey; even light takes more than four decades to get there. But in our imagination we’re there in the blink of an eye. Ultra-cool TRAPPIST-1 is a so-called ultra-cool red dwarf star, which made the news in 2017 because Belgian astronomers discovered seven Earth-like planets in orbit around it. The terms ultra-cool and Earth-like should not be taken too literally. Anything below 2700 degrees Kelvin (more than 2400 degrees Celsius) is considered ultra-cool… Read More

Artist impression of the "Belgian" planet Nervia, portrayed as a gas giant in the black, yellow and red of the national flag, with some moons, a ring and the star Neburonia

The Chronicles of Nervia

A few weeks ago I made an artist impression of the “Dutch” planet Nachtwacht as a red, white and blue, Jupiter-like gas giant. But such a planetary image in the national colors can of course be made for our southern neighbors as well. After all, also Belgium has recently acquired a planet and a star. As part of the NameExoWorlds project of the International Astronomical Union, the Belgian public could name this piece of real estate in the Milky Way galaxy Gaul The name the Belgians have given to “their” planet sounds a lot more euphonious than the guttural Dutch… Read More

Space Quotes

This collection of space quotes, cosmic wisecracks and universal oneliners was originally tweeted from the, nowadays pretty dormant, Modified Mars Twitteraccount. I felt they deserved a more permanent location; after all, colonizing the Galaxy is a long term project. Some of these quotes are funny, others are dead serious; occasionally they’re both. They all are, sometimes very obvious, in other cases rather remotely, linked to themes like Mars, spaceflight, astronomy or the universe in general. And since I call this an image blog, I mix the quotes with some space art I’ve produced over the years. “We are all in the… Read More

Planetary road sign in a museum-like setting showing the directions and distances to the sun, the moon and the seven planets

Building a Planetary Road Sign

There must be many of them: those funny signposts that indicate the direction and the distance to places that are usually quite far away. Tokio 9597 kilometers, Kinshasa 6379 kilometers, Mahabalipuram 8106 kilometers. Wouldn’t it be nice, I thought a few weeks ago, if there was a signpost like that showing the directions and distances for the sun, the moon and the planets? Why doesn’t such a planetary road sign actually exist? Of course I immediately knew the answer. The planets all have their orbits around the sun and the moon revolves around one of those planets: the Earth. And… Read More

Space art, showing the Earth-like planet Alice with a remarkable landscape full of islands and lakes and in the background gas giant Goliath

Alice and Goliath – two worlds out of many

How many Earth-like exoplanets are there in the universe? In other words: how many doubles does our beautiful water world have? We’ll never get anywhere near an exact answer but “very, very much” is, most likely, pretty close to the truth. Billions There are about 200 billion stars in our own galaxy. The number of galaxies in the universe is, coincidentally, also around 200 billion. So we are talking about roughly 40,000,000,000,000,000,000,000 stars. Even if only one in a million stars has an Earth-like planet orbiting around it, which seems like a pessimistic estimate, we still have an unimaginable number… Read More

Close-up of the Earthrise stained glass window showing a piece of the globe with Europe, the Atlantic and North America

Earthrise as a Mosaic and a Stained Glass Window

Earthrise is the name of one of the most iconic images of the twentieth century. The photo, of planet Earth above the gray landscape of the Moon, was taken by astronaut Bill Anders, during the Apollo 8 mission on December 24, 1968, Christmas Eve. Lonely this Christmas Astronauts Frank Borman, Bill Anders and Jim Lovell were incredibly far from home in late December 1968. To boldly go where no one has gone before, indeed. And all this over Christmas. After all, there was a space race going on: staying ahead of the Russians was more important than spending the holidays… Read More

87 Members of the Solar Family

A while ago I made a family portrait of the solar system. Or rather a portrait of the leading members of the family, the eight planets: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars and Mercury. Moons, asteroids and dwarf planets But there’s more happening around the Sun. Moons for instance; our own Moon, of course, but also a large number of satellites of the four gas giants. There is an asteroid belt between the orbits of Mars and Jupiter where, besides a lot of little ones, also bigger objects are turning their rounds. But many asteroids can be found outside… Read More

Group portrait of the eight planets of our solar system, shown to scale: Earth, Venus, Mars and Mercury in their entirety and parts of Jupiter, Saturn, Neptune and Uranus

Portrait of the Planets

When you want to capture the whole Solar System in one image, you come across a problem. The distances between the eight planets and their star are huge, almost unimaginable. In all the pictures of the solar system you’ve ever seen the sizes of the planets are wrong: they are strongly exaggerated, by necessity. On a scale model of about two metres – a nice size to hang on the wall in your living room – the Earth would be only four thousandths of a millimeter. You wouldn’t even be able to see our homeworld! Heaven on Earth The only… Read More
