Very cool stuff, Well it's kinda hot stuff.

A NASA spacecraft watching the sun has caught a dazzling view of a solar eruption that launched a vast tendril of magnetic plasma into space.
NASA's Solar Dynamics Observatory recorded the sun tentacle, which scientists call a solar prominence, on March 19 as it erupted into space with a rounded, twisting motion.
The eruption occurred over five hours as SDO watched the sun in the ultraviolet range of the light spectrum, SDO mission scientists said in a statement. The solar observatory watched as the prominence twisted up from the sun and expanded, then became unstable. [Video: Round Eruption From the Sun.

Japan unfurls Ikaros solar sail in space
Solar Sails , More Sci Fi stuff coming into reality .
BBC
Japanese scientists are celebrating the successful deployment of their solar sail, Ikaros.
The 200-sq-m (2,100-sq-ft) membrane is attached to a small disc-shaped spacecraft that was put in orbit last month by an H-IIA rocket.
Ikaros will demonstrate the principle of using sunlight as a simple and efficient means of propulsion.
The technique has long been touted as a way of moving spacecraft around the Solar System using no chemical fuels.
The mission team will be watching to see if Ikaros produces a measurable acceleration, and how well its systems are able to steer the craft through space.
The Japan Aerospace Exploration Agency (Jaxa) said in a statement that its scientists and engineers had begun to deploy the solar sail on 3 June (JST).
On 10 June, Jaxa said, confirmation was received that the sail had expanded successfully. Some thin-film solar cells embedded in the membrane were even generating power, it added.

Sun-Gazing Observatory Set for Launch
1.5 terabytes of information a day , near Imax resolution !
these should be some awesome pictures .
Technewsworld
NASA hopes to launch its Solar Dynamics Observatory on Thursday, weather permitting. The SDO will capture views of the sun in IMAX-like high definition and return about 50 times more data than any other NASA mission so far. It's important to understand the vagaries of solar activity, because flareups can interfere with power grids, GPS navigation, air travel and all sorts of critical communications systems.
Originally planned for launch on Tuesday, NASA's Solar Dynamics Observatory was delayed once again on Wednesday due to high winds .
The new planned launch for the device from Cape Canaveral Air Force Station in Florida is Thursday, Feb. 11; the launch window is between 10:23 a.m. and 11:23 a.m. EST.
The SDO will undertake a five-year mission to investigate in unprecedented detail the energy processes driving the sun's stormy activity. The 6,555-pound spacecraft will return 1.5 terabytes of data every day -- equal to half a million downloaded songs -- and provide detailed images of near-IMAX-quality high resolution.
