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...

Hubble images of elliptical galaxy yield surprising discoveries Hubble images of elliptical galaxy yield surprising discoveries

Recent Hubble images of Centaurus A, the elliptical galaxy closest to the Milky Way, reveal it is surrounded by a halo of stars much larger than previously thought and that stars within that halo are surprisingly metal-rich...

Astronomers construct most detailed galaxy cluster mass map yet Astronomers construct most detailed galaxy cluster mass map yet

Observations from Hubble’s Frontier Fields observing program has allowed astronomers to map the mass distribution of a galaxy cluster with unmatched detail...

Dwarf galaxies discovered ‘dancing’ around their giant counterparts Dwarf galaxies discovered ‘dancing’ around their giant counterparts

It seems that even galaxies have a sense of rhythm to them. Scientists have uncovered that they "dance" around giant galaxies in a disc-like pattern. This discovery differs from the conventional model about their movements, one which held that the smaller galaxies swarmed around the larger ones...

Scientists: Cosmic tug of war in the stars requires more investigation Scientists: Cosmic tug of war in the stars requires more investigation

According to astronomers, a string of stars -- aligned like a necklace of blue pearls and found along two elliptical galaxies -- could be the result of a galactic merger...
