The SDO's first light image has been released! "First light" refers to an astronomical instrument's first imaging.

NASA held a briefing on 21 April; the image was made on 30 March. The image is false-color; reds denote cooler areas (~60,000 Kelvin), and the blues and greens are hotter (>1 million Kelvin; Kelvin is simply Celsius + 273.15).

SDO was launched in February and is the most advanced orbiting craft ever to study the Sun. It was designed specifically to help us understand how the inside of the Sun works, and how energy is stored and released in the Sun's atmosphere. It's the first mission in NASA's Living With a Star Program, and it'll be sending 1.5 terabytes (that's not a misprint) of data back each day.

Interest goes beyond basic curiosity. So-called "space weather" can disable satellites, cause power grid failures, and disrupt global positioning system and television signals.

NASA received 370 votes for its SDO First Light Anniversary Video Contest, which ran 21 April to 5 May.

The public was asked to vote on the best of ten nice video clips culled from the SDO archive. The winner was "Monster Prominence" which showcased the 24 February spray of plasma, captured in UV. Second place went to the 19 April 2010 "Plasma Rain", in which a hefty amount of plasma material from a prominence falls back to the "surface". "Popping All Over" (from 6 to 8 March, at 17.1 nanometers) beautifully displays flashing rubber bands of magnetic field lines breaking here and there.

An M9.3-class solar flare erupted from a sunspot area this past Friday. The SDO captured the event; since the area of the Sun at which the eruption occured wasn't facing Earth, there were little effects here at home.

Solar storms can last from a few minutes to many hours. The effects of those storms can be present in the Earth's atmosphere for up to several weeks.

On 13 September the SDO's view of the Sun was blocked simultaneously by both the Moon, which began to move into the field of view and partially blocked our parent star, and the Earth which came in next and blocked the view entirely! The event is shown in the video "Earth and Moon Photobomb SDO", which is currently on the second-to-last row of the NASA video archive...

NASA has announced that a live SDO feed of the upcoming Transit of Mercury will be broadcast on Monday 9 May on NASA-TV2. The start time has yet to be determined.

NASA-TV can be accessed at...
