(Phys.org) -- Over the years, cosmologists have found ample evidence of just two kinds of black holes: stellar mass black holes and supermassive black holes. The former are considered small by most standards, just several ...
Solar flares can release the energy equivalent of many atomic bombs, enough to cut out satellite communications and damage power grids on Earth, 93 million miles away. The flares arise from twisted magnetic fields that occur ...
