NASA's legendary Solar Dynamics Observatory (SDO) has observed a new type of explosion on the Sun. Called "forced reconnection," this newly-discovered phenomenon was theorized 15 years ago. The discovery is expected to help scientists understand a…
Following a lunar transit from 11:13 to 12:18 UTC on August 2, 2016, NASA's Solar Dynamics Observatory (SDO) did not go back into Science mode. More than 24 hours after the anomaly occurred, mission managers said the spacecraft is currently in inertial mode….
The Sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on February 11, 2010, SDO keeps a 24-hour eye on the entire disk of the Sun, with a prime view of the graceful dance of solar material coursing through the Sun's…
A small, but complex mass of solar material gyrated and spun about over the course of 40 hours above the surface of the Sun from September 1 – 3, 2015. It was stretched and pulled back and forth by powerful magnetic forces in this sequence captured by NASA’s Solar
February 11, 2015 marks five years in space for NASA's Solar Dynamics Observatory, which provides incredibly detailed images of the whole Sun 24 hours a day.Capturing an image more than once per second, SDO has provided an unprecedentedly clear picture of how massiv
On March 29, 2014 the sun released an X-class flare. It was observed by NASA's Interface Region Imaging Spectrograph, or IRIS; NASA's Solar Dynamics Observatory, or SDO; NASA's Reuven Ramaty High Energy Solar Spectroscopic Imager, or RHESSI; the Japanese Aer
NASA's Solar Dynamics Observatory (SDO), launched on February 11, 2010, keeps a 24-hour eye on the entire disk of the Sun, with a prime view of the graceful dance of solar material coursing through the Sun's atmosphere, the corona. The
Argos (or Argus Panoptes) was the 100-eyed giant in Greek mythology.
While NASA Solar Dynamics Observatory (SDO) has significantly less than 100 eyes, seeing connections in the solar atmosphere through the many filters of SDO presents a number of interesting
On November 28, 2013 at 18:44 UTC Comet ISON will reach its perihelion and fly by about 1.2 million km (730 000 miles) above the solar surface. Since space-based solar observatories will be recording its passage just follow the links and timetable below for
For almost 1 1/2 hours the Moon made an appearance in NASA's Solar Dynamics Observatory's view on August 6, 2013. The Moon itself looks much bigger than the Sun – as the Moon is many times closer to Earth (and to SDO) than the Sun
