Death Star: Eta Carinae, one of the closest stars to Earth is huge and unstable and will likely explode in a supernova in the relatively 'near future' (On an astronomical timeline this could be a million years from now). via NASA #Eta_Carinae #Supernova #NASA
Colors of the Innermost Planet: This image of Mercury was produced by using images from the color base map during MESSENGER's primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury's surface.

A beautiful new image of two colliding galaxies has been released by NASA's Great Observatories. The Antennae galaxies, located about 62 million light-years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red).
NASA announced that it has discovered the first "circumbinary planet"--a planet orbiting two stars. While the planet's officially called Kepler 16b, astronomers are already referring to it as Tatooine, after the home planet of Luke Skywalker in the Star Wars movies, which also had two suns (NASA even invited John Knoll of Industrial Light and Magic, the special-effects company behind Star Wars, to today's announcement).
