In 2014, astronomers found evidence for the existence of two super-Earths orbiting the 10 billion years-old Kapteyn’s star. However, today’s paper is casting doubt on the detection of at least one of these planets, and stellar activity is to blame.
The third Extreme Solar System conference was held between Nov 29 to Dec 4th, in Kona, Hawaii, on the 20th anniversary of the first exoplanet detection around a main sequence star. This astrobite gives a brief overview of the conference.
Can life on exo-worlds build its own habitable environment in extremely unfavourable conditions?
By combining galaxy formation histories and planet formation models, we can estimate the number of potential civilizations in our Universe.
How and where did the first organic molecules emerge? Sophisticated chemistry models for the synthesis of amino acids within planetesimals can help us to decipher these mysteries.
If parallel Universes exist, their fundamental laws of physics may be different to ours. How sensitive is the existence of life to these laws? Read on to find out.
