New findings from the Gaia space telescope suggest that, cosmically speaking, the Milky Way may have destroyed a small galaxy a long time ago. In fact, it looks like the last major collision between our galaxy and another has occurred billions years later than previously suspected. It has long been known that the Milky Way… Read More »
New computer simulations have cast doubt on the possibility of a lake of liquid water buried beneath Mars’ southern ice sheet; This simulation suggests that closely packed layers of ice can produce the same radar reflections as liquid water. In 2018, the European Space Agency Mars Express The orbiter used the MARSIS (Mars Advanced Radar… Read More »
The most distant carbon ever seen was discovered by the James Webb Space Telescope (JWST) in a galaxy we see as existing just 350 million years after the Big Bang. The detection is notable because not only is it the oldest known carbon, it is also the first time an element heavier than hydrogen or… Read More »
Water frosts were seen for the first time at the equator of Mars. It was previously believed that frost was impossible in this region of the Red Planet, which is equivalent to the tropics. The discovery could be crucial for modeling where water is found on Mars and how water is exchanged between the Red… Read More »
A new study suggests that wild African elephants may address each other using personalized calls that resemble personal names used by humans. While dolphins are known to call to each other by imitating the signature whistle of the dolphin they wish to address, and parrots have been found to address each other in a similar… Read More »
