Planetary Family Portrait

This artist's concept depicts a type of dead star called a pulsar and the surrounding disk of rubble discovered by NASA's Spitzer Space Telescope. The pulsar, called 4U 0142+61, was once a massive star until about 100,000 years ago.

Stellar Rubble May be Planetary Building Blocks (Artist Concept)

This plot of data from NASA's Spitzer Space Telescope reveals the light from a 'super Earth' called 55 Cancri e. The planet is the smallest yet, beyond our solar system, to reveal its direct light.

Magician of a Planet Disappears to Reveal Itself

NASA's NuSTAR has taken its first snapshots of the highest energy X-rays in the cosmos, the same kind used by doctors to take pictures of your bones. NuSTAR chose a black hole in the constellation Cygnus as its first target due to its brightness.

NuSTAR's First View of High-Energy X-ray Universe

The unique ultraviolet vision of NASA's Galaxy Evolution Explorer revealed, for the first time, dwarf galaxies forming out of nothing more than pristine gas likely leftover from the early universe.

Signature of a Carbon-Rich Planet

This ultraviolet image (left) and visual image (right) from NASA's Galaxy Evolution Explorer is of the barred ring galaxy NGC 1291. The VIS image is dominated by the inner disk and bar. The UV image is dominated by the low surface brightness outer arms.

Stormy Clouds of Star Birth

This compilation shows the constellation Hercules, as imaged on May 21 and 22, 2003, by NASA's Galaxy Evolution Explorer. The images were captured by the two channels of the spacecraft camera during the mission's 'first light' milestone.
