Mystery Dust Around a Dead Star with a Close Companion Found

  Astronomers using data from NASA’s Wide-field Infrared Survey Explorer, or WISE, have discovered dust in an unusual place–just outside the reach of a binary star system with a short 3-hour orbit. The binary consists of a white dwarf with a red dwarf companion separated by a distance slightly larger than the radius of the [continue reading]

Millions Of Black Holes Uncovered

  NASA’s Wide-field Infrared Survey Explorer (WISE) mission has led to a bonanza of newfound supermassive black holes and extreme galaxies called hot DOGs, or dust-obscured galaxies. The entire sky as mapped by WISE at infrared wavelengths is shown here, with an artist’s concept of the WISE satellite superimposed. Image Credit: NASA/JPL-Caltech/UCLA Images from the telescope [continue reading]

Just a  Few Brown Dwarfs Close to Home

  Astronomers are getting to know the neighbors better. Our sun resides within a spiral arm of our Milky Way galaxy known as the Orion Arm, about two-thirds of the way out from the center. It lives in a fairly calm, suburb-like area with an average number of stellar residents. Recently, NASA’s Wide-field Infrared Survey Explorer (WISE), has [continue reading]

NASA's WISE Mission Sees Skies Ablaze With Blazars

Astronomers are actively hunting a class of supermassive black holes throughout the universe called blazars thanks to data collected by NASA’s Wide-field Infrared Survey Explorer (WISE). The mission has revealed more than 200 blazars and has the potential to find thousands more. This artist’s concept shows a “feeding,” or active, supermassive black hole with a [continue reading]

NASA Creates Most Detailed Picture Of Our Night Sky

NASA unveiled a new atlas and catalog of the entire infrared sky today showing more than a half billion stars, galaxies and other objects captured by the Wide-field Infrared Survey Explorer (WISE) mission. It’s the largest, most detailed infrared view of space, ever. This is a mosaic of the images covering the entire sky as [continue reading]
