An article published in “The Astronomical Journal” reports a study on the potential impact of the activity of a red dwarf several billion years old such as Barnard’s Star on the potential habitability of its planets. A team of researchers used data collected by NASA’s Chandra X-ray Observatory and the Hubble Space Telescope to keep an eye on Barnard’s Star and its flares observing one X-ray flare in June 2019 and two ultraviolet flares in March 2019. Basically, even if a red dwarf becomes quieter over time, its flares can still erode the atmosphere of a rocky planet.
