Powerful superflares from young red dwarf stars, like the one shown in this artist’s concept, can strip the atmospheres from fledgling planets, spelling disaster for any potential life. (Credit: NASA/ESA/D. Player (STScI))
Red dwarfs are small, slowly burning stars that can live for trillions of years before they run out of fuel. And thanks to their generous lifespans, the planets around them (at least those close enough to stay warm) are often considered prime locations for the developm ...read more
Black holes in binary systems can suck matter off their companion star, forming an accretion disk that shines brightly. Studying the light from this disk using simple techniques could allow astronomers to more easily find these black hole systems. (Credit: ESO/L. Calçada)
Black holes are fascinating and cosmically important objects, but because light cannot escape them, they must instead be detected indirectly, such as through their gravitational effects. Discovering black holes this wa ...read more
