WebOct 30, 2024 · The new observations concluded that about 25% of the time, Barnard’s Star unleashes scorching flares, which may damage the atmospheres of planets closely orbiting it. While its only known planet does not have habitable temperatures, this study adds to evidence that red dwarfs may present serious challenges for life on their planets. WebJun 11, 2024 · Red dwarf stars include the smallest of stars, weighing only 7.5% to 50% of our Sun’s mass. Since they are small, they burn at a lower temperature, reaching around 6,380 degrees Fahrenheit / 3,500 degrees Celsius. Since they have low temperatures, red dwarf stars are much dimmer than our Sun.
