@dralexsys From left to right, artist's concepts of the Spitzer, Planck and Kepler space telescopes. NASA extended Spitzer and Kepler for two additional years; and the U.S. portion of Planck, a European Space Agency mission, for one year.

@dralexsys This Dawn framing camera (FC) image of Vesta shows a small crater with ejecta made of dark material, in the center of the image. This crater is roughly 1.25 kilometers (0.78 miles) in diameter, has a reasonably sharp rim and the dark ejecta extends for roughly 1.5 kilometers (0.93 miles).

@dralexsys The peculiar galaxy Centaurus A as seen in longer infrared wavelengths and X-rays. Inner structural features seen in this image are helping scientists to understand the mechanisms and interactions within the galaxy, as are the jets seen extending over thousands of light years from the black hole believed to be at its heart.

@dralexsys This Dawn framing camera (FC) image of Vesta shows the sharp, fresh crater rim of a large crater that is only partly in the bottom right corner of this image. There are a number of areas of bright material slumping from the rim and near the rim of this crater towards its center.

@dralexsys The roughly 20-kilometer-diameter (12-mile-diameter) crater, named Helena, in the center of this image of Vesta has an interesting bipolar morphology. The left side of Helena crater has a fresh and distinctive rim. Dark and bright material crops out of this part of the rim and slumps towards the center of the crater.

@dralexsys The Barnard Merope Reflection Nebula (IC 349) in the Pleiades Cluster. The nebula is a cloud of interstellar gas and dust passing through the Pleiades star cluster at a relative velocity of 11 km/s. IC 349 is currently only 0.06 light-years from the star Merope, located in the upper right corner outside the frame.

@dralexsys Galaxies NGC 4485 (top) and NGC 4490. These galaxies are gravitationally bound, and their interactions have warped them both from spirals to irregulars. The object is located 25 million light years away in the constellation Canes Venatici.

A glare from the sun on the hydrocarbon Kraken Sea on Saturn's moon Titan. This image was taken by the Cassini probe on July 8, 2008. The sea is 1,170 km long and has an area of ​​about 400,000 square kilometers - slightly larger than the Caspian Sea on Earth.
