Assessing the habitability of planets around old red dwarfs
A new study using data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope gives new insight into an important question: how habitable are planets that orbit the most common type of stars in the Galaxy? The target of the new study, as reported in our press release, is Barnard’s Star, which is one of the closest stars to Earth at a distance of just 6 light years. Barnard’s Star is a red dwarf, a small star that slowly burns through its fuel supply and can last much longer than medium-sized stars like our Sun. It is about 10 billion years old, making it twice the age of the Sun.
