La nave espacial que quiere revelar los misterios del Sol

Though many times the size of Earth, this solar eruption—captured in extreme ultraviolet wavelengths on October 4 by NASA's Solar Dynamics Observatory (SDO)—is considered a minor event

Active Region 1678 has grown quickly over a 2 day period, Feb. 19-20, 2013.

SDO Observes Fast-Growing Sunspot

NASA's SDO Observes Fast-Growing Sunspot (The bottom two black spots on the sun, known as sunspots, appeared quickly over the course of Feb.

A Wolf-Rayet Bubble Nebula surrounds a Wolf-Rayet star. There are different types of WR-nebula, based on their formation mechanism: regions nebulae bubbles hydrogen voids and shells (may be assoc. The nebula shown is a 'wind-blown bubbles' type

*Scientists Recreate Earth’s Northern Lights* “For example, we can show the reaction when Io, the satellite of Jupiter, sends particles to Jupiter. We can also simulate the aurora at Neptune and Uranus, when their magnetic fields are directly pointing towards the sun,” said Gronoff. http://www.nasa.gov/larc/scientists-recreate-earth-s-northern-lights/#.UzQ47YVc_EI

Hubble Finds Supernova Companion Star after Two Decades of Searching. Using the Hubble Space Telescope, astronomers have identified the blue helium-burning companion star, seen at the center of the expanding nebula of debris from the supernova.

Solar probe untangles riddle of flux ropes: A NASA space telescope has finally confirmed to solar scientists the processes that produce massive explosions on the Sun. A flare on 18 July, 2012, allowed the Solar Dynamics Observatory to watch the development of a sequence of events that led to a classic eruption termed a Coronal Mass Ejection (CME).  Magnetic field lines in the Sun's corona began to twist about, generating a coil of the hottest material on the Sun, a charged gas called plasma…
