Scientists at MIT, the University of Birmingham, and elsewhere say that astronomers' best chance of finding liquid water, and even life on other planets, is to look for the absence, rather than the presence, of a chemical ...
As astronomers have begun to gather data on the atmospheres of planets, we're learning about their compositions and evolution. Thick atmospheres are the easiest to study, but these same thick atmospheres can hide the surface ...
The way astronomers study planets in our own solar system is surprisingly similar to the way they study exoplanets, despite the latter being orders of magnitude more distant. The key is spectroscopy—examining the wavelengths ...
The Earth is a wonderful blue and green dot covered with oceans and life, while Venus is a yellowish sterile sphere that is not only inhospitable but also sterile. However, the difference between the two is only a few degrees ...
When spacecraft return to Earth, they don't need to shed all their velocity by firing retro-rockets. Instead, they use the atmosphere as a brake to slow down for a soft landing. Every planet in the solar system except Mercury ...
Stars are gravitationally fastened to their galaxies and move in concert with their surroundings. But sometimes, something breaks the bond. If a star gets too close to a supermassive black hole, for example, the black hole ...
How did our species, Homo sapiens, arrive in Western Europe? Published in Nature Ecology & Evolution, our new study analyzes two skull fragments dating back between 37,000 and 36,000 years to conclude that our ancestors came ...
A scientific team led by researchers from the Laboratory for Planetary and Atmospheric Physics (LPAP) at the University of Liège (BE) has just observed, for the first time, lights in the night sky over Mars using the UVIS-NOMAD ...
A multi-institutional team of astrophysicists from Germany has made the first direct observation of oxygen atoms in the day side atmosphere of Venus. In their project, reported in the journal Nature Communications, the group ...
With thousands of known exoplanets and tens of thousands likely to be discovered in the coming decades, it could be only a matter of time before we discover a planet with life. The trick is proving it. So far the focus has ...
