How can we find other pale blue dots? Today’s paper studies what could be the most time-effective way to search for Earth-like exoplanets, just by looking at their colors.
Planets can live very close to one another, but are planetary neighbors destructive to life, or might they help it get started in the first place?
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.
