    On March 13, 2012, the sun erupted with an M7.9-class flare that peaked at 1:41 p.m. EDT. This flare was from the same active region, No. 1429, that has been producing flares and coronal mass ejections all week. That region has been moving across the face of the sun since March 2, and will soon rotate out of Earth view.

      Sunspots and Solar Flares - NASA's Solar Dynamics Observatory (SDO) captured this image of an M7.9 class flare on March 13, 2012

      NASA's Solar Dynamics Observatory (SDO) captured this image of an M7.9 class flare on March 13, 2012. A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and last from mere minutes to several hours.

      BAD GUYS REGROUP: MORE OCCURRENCES LIKE THIS ARE HAPPENING, SHOWING VERY ACTIVE SOLAR CYCLE. Solar flare likely knocked American military satellites offline.

      On March 13, NASA's Solar Dynamics Observatory took this gorgeous image of a solar flare.

      A solar flare captured using the 131 Angstrom wavelength which gives it the teal colour.

    The sun erupted with an X1.7-class solar flare on May 12, 2013. This is a blend of two images of the flare from NASAs Solar Dynamics Observatory: One image shows light in the 171-angstrom wavelength, the other in 131 angstroms. Credit: NASA/SDO/AIA

    A beautiful prominence eruption shot off the east limb (left side) of the sun on Monday, April 16, 2012. Such eruptions are often associated with solar flares, and in this case an M1 class (medium-sized) flare did occur at the same time, though it was not aimed toward Earth. This event, which is still in progress, was seen by NASA’s SDO satellite.

    An M-class solar flare erupts from the right side of the sun in this image from shortly before midnight EST on Jan. 12, 2015. The image blends two wavelengths of light -- 171 and 304 angstroms -- as captured by NASA's Solar Dynamics Observatory.

    This color-coded image combines observations made by NASA's Solar Dynamics Observatory in several extreme ultraviolet wavelengths, highlighting a bright X-class flare toward the upper right of the sun's disk on March 6, 2012.

    These two panels illustrate the intensity of that solar flare in all-sky images recorded by the orbiting Fermi Gamma-ray Space Telescope. On March 6, as on most days, the Sun was almost invisible to Fermi's imaging detectors. But during the energetic X-class flare, it became nearly 100 times brighter than even the Vela Pulsar at gamma-ray energies. Now faded in Fermi's view, the Sun will likely shine again in the gamma-ray sky as the solar activity cycle approaches its maximum.

    Eclipse from Space☆★

    Ten years ago, an explorer from Earth parachuted into the haze of an alien moon toward an uncertain fate. After a gentle descent lasting more than two hours, it landed with a thud on a frigid floodplain, surrounded by icy cobblestones. With this feat, the Huygens probe accomplished humanity's first landing on a moon in the outer solar system. Huygens was safely on Titan, the largest moon of Saturn.

    Coronal holes are regions where the sun's corona is dark. These features were discovered when X-ray telescopes were first flown above the Earth's atmosphere to reveal the structure of the corona across the solar disc. Coronal holes are associated with 'open' magnetic field lines and are often found at the sun’s poles.
