The solar eruption, known as a (CME), occurred at 4:24 a.m. EDT (0824 GMT) Tuesday and blasted billions of tons of solar particles toward Earth at a mind-boggling speed of 2 million mph (3.3 million km/h). "Experimental NASA research models, based on observations from NASA's Solar Terrestrial Relations Observatory, show that the CME left the sun at speeds of around 570...
Strange, Pulsating Star Found
Artist's impression of PSR J1745-2900, a pulsar with a very high magnetic field ( (Ralph Eatough/MPIfR) A strange, pulsing star has revealed a powerful magnetic field around the giant black hole at the heart of Earth’s Milky Way galaxy, scientists say. The finding may help shed light on how the galaxy's devours matter around it and spits out powerful jets of superhot matter, the researchers added. The center of virtually every large galaxy is suspected to host a supermassive black...
