Heliophysics Seeking to understanding the Sun and its interactions with the Earth and solar system. | Sun: Magnetic Arcs ▲ An M5 flare (medium-size) associated with a coronal mass ejection generated a fairly robust radiation storm (May 22-23, 2013). The outburst originated from active region right near the right edge of the Sun. After the eruption, cascades of magnetic loops spun up above the area as the magnetic fields tried to reorganize themselves. When viewed in profile, they put on a marvelous display of solar activity. The images are a combination of two wavelengths of extreme ultraviolet light (at 171 and 304 Angstroms). Credit: NASA's Solar Dynamics Observatory. » More info on this image |

CGRO Mission 25th Launch Anniversary
The Compton Gamma Ray Observatory (CGRO) was the second of NASA's Great Observatories. Compton, at 17 tons, was the heaviest astrophysical payload ever flown at the time of its launch twenty-five years ago on April 5, 1991 aboard the space shuttle Atlantis. Compton was safely deorbited and re-entered the Earth's atmosphere on June 4, 2000.
