A fresh study examining data from NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft has led to to the discovery of the brightest galaxy in the universe. The galaxy, dubbed WISE J224607.57-052635.0, is believed to contain in excess of 300 trillion stars, and has given rise to a new group of astronomical objects – Extremely Luminous Infrared Galaxies, or ELIRGs.

NASA's Spitzer and WISE telescopes find star colder than the North Pole

By - April 28, 2014 8 Pictures
We tend to think of stars as being very, very hot, but what about a star that you could use as a deep freeze? Astronomers using NASA's Wide-field Infrared Survey Explorer (WISE) and Spitzer Space Telescope have discovered a dim star-like object with the catchy title WISE J085510.83-071442.5.0 that is colder than the North Pole. Lying about 7.2 light years from Earth, it is not only the coldest brown dwarf on record, but the fourth-closest star system to the Solar System. Read More

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) has sent back the first test images from its 16-in (40-cm) telescope and infrared cameras as it is prepared for its new mission. Intended to seek out potentially dangerous asteroids and help in selecting a near-Earth object as part of the space agency’s asteroid retrieval effort, NASA says NEOWISE will be a powerful tool for discovering, cataloging and understanding the asteroids in the inner Solar System.

Binary star system found right under our noses

By - March 13, 2013 3 Pictures
In a day when we have examined astronomical objects shining forth from a time shortly after the Big Bang, one would think astronomers have a pretty good handle on what is in the immediate vicinity of the Solar System. That's why the recent report of a binary star lying only 6.5 light-years away came as rather a surprise to the astronomical community. The pair, called WISE J1049-5319 A and B, are brown dwarf stars and only two star systems – the triple star Alpha Centauri, and Barnard's Star – lie closer to our Sun. Read More
