Brightest galaxy ever discovered may be tearing itself apart

According to a new study, the brightest galaxy ever discovered may be in the process of tearing itself apart. WISE J224607.57-052635.0 (W2246-0526) is believed to be brighter than 300 trillion Suns, however the cause of this brightness – the supermassive black hole at the centre of the galaxy – could also be responsible for a drastic transformation.Read More

Astronomers discover massive galaxy cluster 8.5 billion light-years from Earth

Astronomers have discovered a massive galaxy cluster located an impressive 8.5 billion light-years from Earth. It is hoped that further analysis of the cluster, which has been imaginatively named Massive Overdense Object (MOO) J1142+1527 (MOO J1142+1527), will allow scientists to shed some light on the evolution of some of the largest structures in our Universe.Read More

Study lends support to prevailing model of Milky Way structure

Results from a new technique designed to map the structure of the Milky Way appear to support the four spiral arm model of our galaxy. A team of researchers from the Federal University of Rio Grande do Sul, Brazil, used data collected by NASA's Wide-field Infrared Survey Explorer (WISE) spacecraft to pinpoint star clusters located in the resource rich environment of the spiral arms, and use them as markers to trace the structure of our galaxy.Read More

Orbital telescopes detect increased activity from the supermassive black hole at the heart of the Milky Way

Three space-based observatories appear to have picked up an unusual increase in activity from the supermassive black hole located at the center of our galaxy. According to the data, the black hole known as Sagittarius A* (Sgr A*), which has a mass of roughly 4 million times our Sun, is throwing out ten times the usual amount of bright X-ray flares.Read More

New study tracks the death of our Universe

A new study has measured 200,000 galaxies in an effort to chart the rate at which our Universe is outputting energy, and effectively dying. The study is part of the larger Galaxy And Mass Assembly (GAMA) project, a comprehensive spectroscopic survey seeking to create a model of energy production by the Universe, both in the present day and in times past.Read More

WISE discovers brightest galaxy in the universe

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.Read More

Black hole doughnut theory cast into doubt

A fresh analysis of data collected by NASA's WISE telescope has cast doubt on the widely accepted unified model for the composition of black holes. The study examined 170,000 supermassive black holes, and will require scientists to present new theories on the structure of these stellar giants.Read More

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

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 NEOWISE discovers its first new near-Earth asteroid since returning to work

NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) may have only come back online last September after a 31-month hibernation, but it’s already producing results. According to the space agency, the unmanned spacecraft discovered a never-before-seen asteroid on December 29 – the first discovery of its new mission to seek out potentially hazardous near-Earth objects (NEOs).Read More
