Mars has a curious past. Rovers have shown unequivocal evidence that liquid water existed on its surface, for probably at least 100 years. But climate models haven’t come up with how exactly that happened with what we currently understand about what the Martian climate was like back then. A new paper, published in the journal AGU Advances by Eleanor Moreland, a graduate student at Rice University, and her co-authors, has a potential explanation for what might have happened - liquid lakes on the Red Planet would have hid under small, seasonal ice sheets similar to the way they do in Antarctica on Earth.

ESA Director General’s 2026 annual press briefing
Video: 01:30:00
Josef Aschbacher, Director General of the European Space Agency, briefed journalists on the main milestones for 2026, such as the launch of Smile, a mission that will give humankind its first complete look at how Earth reacts to streams of particles and bursts of radiation from the Sun. Later in 2026 should also see the arrival of BepiColombo at Mercury after its eight-year trip, where it will gather data to answer many perplexing questions about the least-explored planet of the inner Solar System. Many more exciting missions are expected, with ESA astronaut Sophie Adenot launching for the International Space Station, and various Earth Observation and Navigation launches from Europe’s Spaceport in French Guiana.

Tiny patches of deforestation drive tropical carbon loss
Often called Earth’s green lungs, tropical forests pull down massive amounts of carbon dioxide from the atmosphere, release oxygen and help regulate the global climate. While the threat of large-scale deforestation is well known, new findings reveal a surprising culprit – the clearance of small areas of forest accounts for more than half of net carbon losses across the Tropics.

NASA Releases the Long-Awaited Video of Kepler's Supernova Remnant
In 1604, German astronomer Johannes Kepler spotted a new star in the sky that was so bright it could be seen during the daytime. The discovery, which Kepler described in his book *De Stella Nova*, caused quite a stir in the astronomical community. With this one point of light, astronomers questioned the prevailing dogma that the "firmament" (the background stars in the sky) was not unchanging and permanent. In time, we would come to realize that Kepler's Supernova (as it's come to be known) was a white dwarf that exceeded its critical mass and exploded in a brilliant burst.
