NASA On March 2, 2013, NASA´s Solar Dynamics Observatory (SDO) entered its semiannual eclipse season, a period of three weeks when Earth blocks its view of the sun for a period of time each day. On March 11, however, SDO was treated to two transits. Earth blocked SDO´s view of the sun from about 2:15 to 3:45 a.m. EDT. Later in the same day, from around 7:30 to 8:45 a.m. EDT, the moon moved in front of the sun for a partial eclipse. When Earth blocks the sun, the boundaries of...

[Watch Video: Fiery Looping Rain On The Sun] Lee Rannals for redOrbit.com — Your Universe Online An eruption on the sun can be a beautiful, monstrous event, and NASA's Solar Dynamics Observatory (SDO) has helped to bring these dangerous, yet breathtaking events right to our computer screens. On July 19, 2012, the sun erupted in a solar flare, ejecting material called a coronal mass ejection (CME), creating a loop in the sun's atmosphere known as the corona. This moderately...

NASA [ Watch The Video ] On Feb. 11, 2010, NASA launched an unprecedented solar observatory into space. NASA's Solar Dynamics Observatory (SDO) flew up on an Atlas V rocket, carrying instruments that scientists hoped would revolutionize observations of the sun. If all went according to plan, SDO would provide incredibly high-resolution data of the entire solar disk almost as quickly as once a second. When the science team released its first images in April of 2010, SDO's data...

Lee Rannals for redOrbit.com — Your Universe Online When we take a glance at the sun, or sit down with paint to color the sky, we always see our home star as yellow, but the sun is full of much more diversity. The reason we only see yellow is because it is the brightest wavelength of light from the sun, but with special instruments, NASA is able to see all the wavelengths. With these instruments, whether they are in ground-based or space-based telescopes, we can observe light...
