Most of the #exoplanets we've discovered orbit red dwarf #stars. This is because about 75% of the stars in the Milky Way are red dwarfs, so you would expect red dwarf planets to be the most abundant. This also means that most #habitable worlds are going to orbit these small, cool stars, and that has some significant consequences for our search for #life. But even detecting the atmospheres of such planets may be extremely difficult in practice. #astronomy #astrobiology phys.org/news/2024-09-exoplanets-atmospheres.html
