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

I beg your pardon? The end of history? Perhaps history has just begun. If we take care to not mess up things on our own planet, there is a universe waiting for us.
I sometimes think that my fascination with space and astronomy are related to the fact I saw the Apollo 11 moon landing as a seven-year-old. On the other hand, Arthur C. Clarke, Carl Sagan and Brian Cox at that time were respectively 51, 34 and 1 years old, so maybe age does not matter that much.
Anyway, the final frontier, has always had my warm interest. In the past I have made work for organizations such as The Mars Society and Explore Mars. With my own collection of Space Art I carefully follow in the footsteps of legends like Chesley Bonestell, Pat Rawlings and Don Dixon.
Over a year ago, I was asked if I wanted to have an exhibition of my work in the entrance hall of the RIVM, the Dutch National Institute for Public Health and the Environment in Bilthoven. At that time, I had only a vague idea of the existence of that institute. But then first the emissions of nitrogen by agriculture and industry created a kind of national crisis in which the institute played a pivotal role. And after that the covid-19 pandemic came upon us. By now, there is probably nobody in the country who has never heard of RIVM.… Read More
The closest planet in our solar system, Venus, looks suspiciously like Earth, at first glance. With a diameter of 12,104 kilometers, Venus is only a few percent smaller than Earth (12,757 kilometers). Gravity is also only a fraction less: 0.9 g. That similarity is very striking when you consider that the planets orbiting our sun vary enormously in size, from the dwarf Mercury to the giant Jupiter. As a child I was fascinated by this twin sister of the Earth. I even drew a map, not based on any scientific knowledge, with seas, continents, mountain ranges and wave currents. The… Read More
Kim Stanley Robinson’s Mars trilogy is one of the highlights of American science fiction, as far as I’m concerned. Red Mars, Green Mars and Blue Mars were published between 1992 and 1996 and tell the future history of our neighboring planet over a period of almost two hundred years. In those two centuries, Mars is fully terraformed: transformed from a cold, dry, lifeless desert into a living world with seas, forests and cities. Not all main characters are happy with those changes: the battle between the Reds, who prefer to keep Mars as it is and the Greens, for whom… Read More
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 piece of real estate in the Milky Way galaxy, as part of the NameExoWorlds project of the International Astronomical Union. Gaul The name the Belgians have given to “their” planet sounds a lot more euphonious than the guttural Dutch Nachtwacht: Nervia. Well, of course the name had to be… Read More
Since December 17, the Netherlands has two new far outposts: the planet Night Watch and the star Starry Night. The IAU, the International Astronomical Union, asked us to come up with a name for those two celestial bodies, which were previously known under the somewhat boring character combinations HAT-P-6 and HAT-P-6b. The inhabitants of the 111 other countries affiliated with the IAU were also assigned a cosmic duo, as part of the NameExoWorlds campaign. Rembrandt and Van Gogh Out of 6,000 suggestions submitted by the public, the national jury chose a shortlist of five name twins, of which Nijntje (Miffy)… Read More
This collection of space quotes, cosmic wisecracks and universal oneliners was originally tweeted from the, nowadays pretty dormant, Modified MarsTwitteraccount. 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 illustrate this page with some space art I’ve produced over the years. “We are all in the gutter,… Read More
After terraforming Mars quite a few times, I’ve now done the reverse thing: martifying Earth. What would our planet look like if all the water suddenly disappeared? Like a Pale Yellow Dot, a kind of cross-over between the Moon and Mars. Warming-up No, this is not a warning about the effects of global warming. Those are worrying enough, but in the short term they mainly mean that we have to deal with more instead of less water. Speculation On the other hand: sometimes planets lose a lot of water in the course of their existence. Mars, for example, once had… Read More
Among the general public, there’s remarkably little awareness of the solar system, our immediate environment, our neighbourhood. Many people simply don’t know the difference between the solar system, the galaxy and the universe. Even Dutch national quality newspaper the Volkskrant once wrote that Jupiter is the largest planet in the universe (I’ll never forgive them). Naming the eight planets in the right order is a basic skill that few people posses. Knowledge about the size and mutual distances of these celestial bodies is also very limited. Beach balls For some reason, many people think that Mars is bigger than the… Read More
The last few weeks, I have once again been busy with an old hobby of mine: terraforming. A word that the spelling checker does not even know, but in science-fiction one can read it quite often: it’s about making other planets more friendly for lifeforms from Earth by adjusting the temperature and the atmosphere. Mars and Venus The terraforming of Mars is actually not that complicated. Simply pumping CO2 and other greenhouse gases into the atmosphere will start a runaway greenhouse effect that turns up the heat and thickens the atmosphere. On our homeworld we are already practicing, unintentionally. What… Read More
