This Hubble image shows NGC 1156, a dwarf irregular galaxy located 25 million light-years away in the constellation of Aries. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Planetary Camera 2 (WFPC2) and Advanced Camera for Surveys (ACS). It is based on data obtained through five filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

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 illustration plots changes in the brightness of Betelgeuse, following the titanic mass ejection of a large piece of its visible surface; the escaping material cooled to form a cloud of dust that temporarily made the star look dimmer, as seen from Earth; this unprecedented stellar convulsion disrupted the monster star’s 400-day-long oscillation period that astronomers had measured for more than 200 years; the interior may now be jiggling like a plate of gelatin dessert.
