Scientists stunned to find cluster of quasars aligned perfectly together Scientists stunned to find cluster of quasars aligned perfectly together

Researchers studying 93 quasars, or active galactic nuclei, were stunned to discover that their rotation axes and the supermassive black holes at their centers align with one another...

Enormous object at Milky Way’s center is finally identified Enormous object at Milky Way’s center is finally identified

G2 is a mysterious object in the heart of our Milky Way galaxy. It has been postulated that G2 is an immense cloud of hydrogen gas on course to be devoured by Sagittarius A*, the supermassive black hole at the Milky Way’s center...

In older galaxies, black hole emissions impede star formation In older galaxies, black hole emissions impede star formation

Radio waves and heat emitted by super-massive black holes can impede the formation of new stars, especially in older, elliptical galaxies. Most galaxies have super-massive black holes at their centers...

Massive galaxies don’t form new stars, but get bigger by consuming neighbors Massive galaxies don’t form new stars, but get bigger by consuming neighbors

A new study led by Dr. Aaron Robotham of the University of Western Australia node of the International Centre for Radio Astronomy Research (ICRAR) has found that the universe’s most massive galaxies are growing by consuming neighboring dwarf galaxies...

Density map of Milky Way shows 219 million stars Density map of Milky Way shows 219 million stars

The disk of the Milky Way, a region which is the densest in our galaxy, extends over 100,000 light-years. So populated with stars, gas, and dust is the disk that the naked human eye is unable to discern individual objects...

Milky Way part of newly discovered supercluster Milky Way part of newly discovered supercluster

A new study has revealed that our Milky Way galaxy is just one member of a vast and hitherto unrecognized galactic supercluster. Researchers led by R. Brent Tully of the University of Hawaii at Manoa used the National Science Foundation’s Green Bank Telescope (GBT) and other radio telescopes to obtain the new observations...

Early galaxy ‘Sparky’ was a star factory Early galaxy ‘Sparky’ was a star factory

In the hotter, more violent environment of the early Universe, extremely massive galaxies formed. Observing the formation of these giant galaxies has been problematic due to shrouds of dust around their cores, which block visible light...

Telescopes capture unprecedented view of early colliding galaxies Telescopes capture unprecedented view of early colliding galaxies

According to a European Southern Observatory (ESO) statement, an array of ground and space telescopes has obtained amazing new images of a distant galactic collision that occurred when the Universe was half of its current age of 13...

Scientists discover distant galaxy that acts as gravitational lens Scientists discover distant galaxy that acts as gravitational lens

Scientists have discovered an elliptical galaxy 9.6 billion years away that can be used as a gravitational lens to magnify an even more distant galaxy astronomers would normally be incapable of seeing...

Study confirms role of ‘local hot bubble’ in X-ray background Study confirms role of ‘local hot bubble’ in X-ray background

Peering into the night sky with X-ray detectors, an observer would witness the whole sky lit up with the glow of the diffuse X-ray background. Five decades after its discovery, the origins of this X-ray glow are enigmatic...
