Powerful blasts of radiation by young stars detected - space science news

Astronomers have observed a red dwarf star in a violent outburst, which was more powerful than ever detected from the sun. This powerful blast would likely prevent the habitability of any planets orbiting the red dwarf. The blast is likely powered by intense magnetic fields that get tangled by the roiling motions of the stellar atmosphere. When tangling gets too intense, the fields break, reconnect and unleash a tremendous amount of energy. The observation was made as part of a Hubble Telescope observing program.
