The Sun

The Swedish 1-m Solar Telescope, operated by the Institute for Solar Physics, has captured images that let you see the sun in an entirely new way:

Mercury up close

NASA's MESSENGER spacecraft flew past Mercury and sent more than 1,200 high-resolution images back to Earth. This picture was taken at the closest approach to Mercury, when the spacecraft was at a distance of about 27,000 kilometers (about 17,000 miles). Read the whole story here, and look at the photo gallery.

What happens on Mars?

This sequence of nine images taken by the Surface Stereo Imager on NASA's Phoenix Mars Lander shows the sun rising on the morning of the lander's 101st Martian day after landing.

The images were taken on Sept. 5, 2008. The local solar times at the landing site for the nine images were between 1:23 a.m. and 1:41 a.m.

NASA's Phoenix Mars Lander observed clouds drifting across the horizon in the early morning on the 119th sol, or Martian day, since landing (September 25, 2008).
