NASA’s Magnetospheric Multiscale (MMS) Mission: Studying magnetic fields around the Earth

By looking close to home, NASA’s newest mission with provide a window to the universe. Countdown to MMS Launch The Magnetospheric Multiscale, or MMS, mission was created to study how magnetic fields around Earth interact with activity from the sun. The […]

Three Years of SDO Images – Narrated Video

NASA's Goddard Space Flight Center heliophysicist C. Alex Young highlights many interesting aspects of the Solar Dynamics Observatory (SDO) images and points out several of the single-frame events that appear in it. This video shows those three years of the sun at a pace of two images per day.

Two giant swaths of radiation, known as the Van Allen Belts, surrounding Earth were discovered in 1958. In 2012, observations from the Van Allen Probes showed that a third belt can sometimes appear. The radiation is shown here in yellow, with green representing the spaces between the belts. Credit: NASA/Van Allen Probes/Goddard Space Flight Center

Van Allen Probes Discover a 3rd Radiation Belt around Earth

Learn about this new result in a video by NASA Goddard Heliophysics Division. NASA presented these results at a press conference today. Tomorrow I will be on a Google Hangout with several of my colleagues at NASA Goddard. http://bit.ly/YzL5Mz Ask […]

This image is from one of my own pieces of work involving RHESSI data, and on which Alex was a co-author. It shows two X-ray sources high up in the corona merging together during a CME eruption. The merging occurred as the CME began to accelerate and appeared to result in intense radio emission implying that particle acceleration had taken place. This suggested that both the flare and the CME were driven by the same energy release at a location high up in the solar corona.

Happy 10th RHESSI!

Ten years ago yesterday (5 February 2002) saw the launch of the Reuven Ramaty High-Energy Solar Spectroscopic Imager, or RHESSI (pronounced reh-see). RHESSI was designed to study particle acceleration and energy transport during solar flares by observing the highest energy […]

Happy Birthday SOHO!! 15 Years!!

The Solar and Heliospheric Observatory or SOHO is by many accounts the granddaddy of modern solar astronomy. SOHO is not the first space based solar observatory but it has truly ushered in a golden age for solar physics. The mission […]

The Launch of the Solar Dynamics Observatory (part 2)

Thursday morning seemed to take longer to arrive. Expectations were certainly higher, based in no small part on the fact that most of us had flights booked to take us home later that day. Washington DC had just gotten its […]

The Launch of the Solar Dynamics Observatory (part 1)

Getting out of Washington DC was not going to be easy. The city was bracing itself for the biggest snowstorm in almost a century over the weekend. The launch of the Solar Dynamics Observatory (SDO; the first mission from NASA’s […]
