A breathtaking compilation of solar views you don't want to miss.
Ever since NASA's Solar Dynamics Observatory (SDO) began collecting images in April 2010, it has delivered incredible views of the sun ranging from stunning to downright explosive. In the past two years, the sun generated more than 1,000 outbursts, including solar flares, coronal mass ejections and energetic particles that travel to the edge of the solar system. By recording these events in multiple wavelengths, scientists can unravel the process by which the roiling magnetic fields inside and around the sun cause it to erupt. For example, the above image showing light at 171 Angstroms and colorized in gold reveals the looping arcs of particles that coalesce around magnetic field lines in the sun's atmosphere during intense periods of solar activity. Other wavelengths make different features more readily visible to the human eye. Watch the video below highlighting some of the most amazing moments witnessed by SDO in its second year of operation.
