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 CME traveled at over 900 miles per second. It did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, with a glancing blow, causing aurora to appear on the night of September 3.

This Hubble image shows NGC 6569, a globular cluster located in the constellation of Sagittarius. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
