This frame from an animation shows the coldest brown dwarf yet seen, and the fourth closest system to our sun. Called WISE J085510.83-071442.5, this dim object was discovered through its rapid motion across the sky.
The third closest star system to the sun, called WISE J104915.57-531906, center of large image, which was taken by NASA's WISE. It appeared to be a single object, but a sharper image from Gemini Observatory, revealed that it was binary star system.
Radiation and winds from massive stars have blown a cavity into the surrounding dust and gas, creating the Trifid nebula, as seen here in infrared light by NASA's Wide-field Infrared Survey Explorer, or WISE.
NASA's NEOWISE spacecraft opened its 'eyes' after more than two years of slumber to see the starry sky with the same clarity achieved during its prime mission. This image shows a patch of sky in the constellation Pisces.
A dying star, called the Helix nebula, is shown surrounded by the tracks of asteroids in an image captured by NASA's WISE. Skirting around the edges of the Helix nebula are the footprints of asteroids marching across the field of view.
