Comet ISON Streams Toward the Sun

Comet ISON is seen the lower right of this image from the ESA/NASA Solar and Heliospheric Observatory mission, captured at 3:07 a.m. EST on Nov. 27, 2013. A cloud of solar material, called a coronal mass ejection, is seen under the sun.

    Comet ISON Streams Toward the Sun | NASA In the early hours of Nov. 27, 2013, Comet ISON entered the field of view of the European Space Agency/NASA Solar and Heliospheric Observatory. In this picture, called a coronagraph, the bright light of the sun itself is blocked so the structures around it are visible. Comet ISON, which began its trip from the Oort cloud region of our solar system, will reach its closest approach to the sun on Thanksgiving Day, skimming just 730,000 miles above the sun.

This movie shows Comet ISON orbiting around the sun – represented by the white circle -- on Nov. 28, 2013. ISON looks smaller as it streams away, but scientists believe its nucleus may still be intact. The video covers Nov. 27, 2013, 3:30 p.m. EST to Nov. 29, 2013, 8:30 a.m. EST.

Graceful Eruption A solar prominence began to bow out and the broke apart in a graceful, floating style in a little less than four hours (Mar. 16, 2013). The sequence was captured in extreme ultraviolet light. A large cloud of the particles appeared to hover further out above the surface before it faded away. Credit: Solar Dynamics Observatory/NASA

This still image was taken from a new NASA movie of the sun based on data from NASA's Solar Dynamics Observatory, or SDO, showing the wide range of wavelengths – invisible to the naked eye – that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors.

The Sun erupted with two prominence eruptions, one after the other over a four-hour period (Nov. 16, 2012).

On August 31, 2012 the Sun threw a major tantrum. It started with a vast arc of material towering over its surface, a stream of plasma flowing between two sunspots. Sometimes these collapse back down to the Suns surface, but this one exploded, blasting hundreds of millions of tons of material out into space. SDO captured this ridiculously awesome picture of the arc just before it erupted!
