Exoplant and red dwarf stellar flares, illustration. Red dwarf star undergoing powerful eruptions called stellar flares, with a planet in the foreground. Red dwarfs tend to be magnetically active, displaying gigantic arcing prominences and a wealth of dark sunspots. Red dwarfs also erupt with intense flares that could strip a nearby planet's atmosphere over time. Studying the light from 215, 000 red dwarfs in observations by NASA's Hubble Space Telescope, astronomers found 100 stellar flares taking place over the course of a week. Image published in 2011. | |
