A team of astrophysicists from the University of Bordeaux and Observatoire Astronomique de l'Université de Genève is suggesting that some exoplanets may not have been too hot during their formative years to harbor life ...
A small team of astrophysicists from the California Institute of Technology, the MIT Kavli Institute for Astrophysics and Space Research and the University of Amsterdam has discovered a binary system with two stars so small ...
Life around an ill-tempered red dwarf star is no fun for accompanying newborn planets. Call it a baptism of fire. Entangled magnetic fields cause a red dwarf to spit out "super-flares" that are 100 to 1,000 times more powerful ...
