NASA just released some great images and video clips taken by Hinode, a Japanese space telescope studying the sun. As described by New Scientist,
The restless bubbling and frothing of the Sun’s chaotic surface is astonishing astronomers who have been treated to detailed new images from a Japanese space telescope called Hinode.
The observatory will have as dramatic an impact on our understanding of the Sun as the Hubble Space Telescope has had on our view of the universe beyond, scientists told a NASA press conference in Washington, DC, US, on Wednesday.

Taken by Hinode’s Solar Optical Telescope on Nov. 11, 2006, this image reveals the fine scale structure in the chromosphere that extends outward above the top of the convection cells, or granulation, of the photosphere. The structure results from the interaction of hot ionized gas with the magnetic field.
This incredible activity is taking place along the entire surface of the sun, all the time. It’s amazing: the sun appears unchanging and placid from Earth, yet its surface (and interior) are alive with activity.
Hinode (formerly known as SOLAR-B), is a satellite with three instruments: the Solar Optical Telescope, X-ray Telescope, and Extreme Ultraviolet Imaging Spectrometer. Its purpose is to study the sun. It is primarily run by JAXA, the Japanese Aerospace Exploration Agency, in collaboration with the space agencies of the United States, the United Kingdom, and the European Union.
