NASA | Incandescent Sun

This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames are in the 171 Angstrom wavelength of extreme ultraviolet. This wavelength shows plasma in the solar atmosphere, called the corona, that is around 600000 Kelvin. The loops represent plasma held in place by magnetic fields. They are concentrated in "active regions" where the magnetic fields are the strongest. These active regions usually appear in visible light as sunspots. The events in this video represent 24 hours of activity on September 25, 2011. This video is public domain and can be downloaded at: svs.gsfc.nasa.gov Like our videos?

NASA | Forest Recovering From Mt St Helens Eruption

The 1980 eruption of Mount St. Helens leveled surrounding forest, blasted away over a thousand feet of the mountain's summit, and claimed 57 human lives. Landsat satellites have tracked the recovery of the surrounding forest. This video shows that recovery, in a timelapse of annual images from 1979-2011.

NASA | Colliding Neutron Stars Create Black Hole and Gamma-ray Burst

Armed with state-of-the-art supercomputer models, scientists have shown that colliding neutron stars can produce the energetic jet required for a gamma-ray burst. Earlier simulations demonstrated that mergers could make black holes. Others had shown that the high-speed particle jets needed to make a gamma-ray burst would continue if placed in the swirling wreckage of a recent merger. Now, the simulations reveal the middle step of the process--how the merging stars' magnetic field organizes itself into outwardly directed components capable of forming a jet. The Damiana supercomputer at Germany's Max Planck Institute for Gravitational Physics needed six weeks to reveal the details of a process that unfolds in just 35 thousandths of a second--less than the blink of an eye.

Subscribe to NASA on iTunes! phobos.apple.com Or get tweeted by NASA: twitter.com Celebrating its 50th Anniversary in 2009, Goddard Space Flight Center has seen a lot of changes over its first five decades. Yet despite the time that has passed, the core values and mission of the center has changed little. This vintage film from 1976 shows a time-capsule glimpse of GSFC's early foundations and how remarkably relevant they remain today. Find out more: www.nasa.gov

NASA | Marco Midon - Black History Month

This video profile shows how one individual has let neither race nor visual impairment keep him from becoming one of NASA's most talented engineers. As a Lead Systems Engineer, Marco Midon oversees the design and implementation of NASA ground stations in the area of radio frequencies. Working with new, higher data-rate dishes at White Sands in New Mexico, he was instrumental in two recent successfully launched NASA missions - the Solar Dynamics Observatory (SDO) and the Lunar Reconnaissance Orbiter (LRO). He is also the Lead Systems Engineer for the new ground station at the McMurdo Station in Antarctica. Marco's extraordinary work continues in updating compatibility equipment testing for the next generation of vehicles and spacecraft. Want more?

NASA | Aqua's AMSR-E Scans Earth's Water Cycle

From June 2002 to early October 2011, the Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E) on the Aqua satellite provided a wealth of data about the Earth's water cycle. Among the many variables calculated from AMSR-E data are sea surface temperature, atmospheric water vapor, rainfall, Arctic and Antarctic sea ice coverages, and snow cover. The AMSR-E data allow the calculation of surface variables under nearly all weather conditions, irrespective of cloud cover and irrespective of whether it is daytime or nighttime. AMSR-E was provided to NASA's Aqua program by the Japan Aerospace Exploration Agency (JAXA), which also has a follow-on AMSR-2 instrument scheduled to be launched in 2012.
