Astronomers spot enormous twin stars heading for a cataclysmic end

Using the ESO's Very Large Telescope, astronomers have discovered a pair of enormous stars, known as an overcontact binary system, that orbit so close to each other that a bridge of stellar material has formed. Scientists predict that at some point, the strange partnership will end in spectacular fashion, with the stellar bodies either merging to create a single titanic star, or in a violent supernova, that would birth a binary black hole system.

New study finds common link between young stars and black holes

A research project led by the University of Leicester in the UK has identified similarities in the readings from the discs surrounding black holes and young stars, even though the objects have wildly different properties. The discovery was made by studying the brightness variations produced by accretion discs around various astronomical objects. These huge discs of matter play a central part in the growth of most objects in the Universe, providing a common ground for study.

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.

Researchers theorize two mechanisms that prevent prolific star creation in galaxy clusters

For a long time, scientists have been searching for an answer as to how galaxy clusters regulate the number of stars they create. Given that the amount of interstellar gas used to create the stellar giants exists in such abundance, this theoretically allows for the creation of many times the current number of stars. A team of researchers from MIT, Columbia University and Michigan State University believe they have found the answer. Read More

NASA aims to unlock mysteries of celestial giants by observing rare black hole

Ever since they were theorized by Albert Einstein's theory of general relativity back in 1915, black holes have captured the imagination and curiosity of the public and scientists alike. However, despite this popularity, relatively little is known about how these all-consuming giants evolve and shape the environment around them. NASA scientists are hoping to unravel some of these mysteries by observing an intermediate-mass black hole (IMBH) sitting 100 million light years away in the spiral arm of galaxy NGC 2276. Read More
