On August 31, 2012 the Sun threw a major tantrum. It started with a vast arc of material towering over its surface, a stream of plasma flowing between two sunspots. Sometimes these collapse back down to the Sun’s surface, but this one exploded, blasting hundreds of millions of tons of material out into space. SDO captured this ridiculously awesome picture of the arc just before it erupted
This photo from NASA's Hubble Space Telescope shows an ominous pillar of gas and dust known as the Cone Nebula. The image shows the top portion of the nebula that is 2.5 light years in height. The Cone Nebula is 2,500 light-years from Earth in the Monoceros constellation. The red halo of light seen around the pillar is caused when ultraviolet radiation causes hydrogen gas in the nebula to glow.
Magnificent CME Erupts on the Sun - August 31 On August 31, 2012 a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth's magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3.
NASA Hubble Finds a True Blue Planet By NASA Goddard Photo and Video This illustration shows HD 189733b, a huge gas giant that orbits very close to its host star HD 189733. The planet's atmosphere is scorching with a temperature of over 1000 degrees Celsius, and it rains glass, sideways, in howling 7000 kilometre-per-hour winds.
