A Dark Matter bridge in our cosmic neighborhood
Jul 15, 2015 (SPX)
By using the best available data to monitor galactic traffic in our neighborhood, Noam Libeskind from the Leibniz Institute for Astrophysics Potsdam (AIP) and h...
What happens when cosmic giants meet galactic dwarfs?
Jul 14, 2015 (SPX)
When two different sized galaxies smash together, the larger galaxy stops the smaller one making new stars, according to a study of more than 20,000 merging gal...
NOAO: NGC 2346 - A Cosmic Butterfly's Delicate Wings
Jul 10, 2015 (SPX)

A galaxy in bloom
Jul 10, 2015 (ESA)
The ghostly shells of galaxy ESO 381-12 are captured here in a new image from the NASA/ESA Hubble Space Telescope, set against a backdrop of distant galaxies. T...
Super-bright supernova with extreme burst of gamma radiation
Jul 10, 2015 (SPX)
Astronomers from the Niels Bohr Institute have observed a super-bright supernova association with a very unusual long lasting gamma-ray burst. Gamma-ray bursts ...
Biggest explosions in the universe powered by strongest magnets
Jul 10, 2015 (SPX)
Gamma-ray bursts are one of the outcomes associated with the biggest explosions to have taken place since the Big Bang. They are detected by orbiting telescopes...
A five star, doubly-eclipsing star system
Jul 10, 2015 (SPX)
Astronomers at the Open University have discovered the first quintuple star system containing two eclipsing binary stars. Details of the five star system, the f...
Huge new survey to shine light on dark matter
Jul 10, 2015 (SPX)
Around 85% of the matter in the Universe is dark, and of a type not understood by physicists. Although it doesn't shine or absorb light, astronomers can detect ...
The dark side of galactic radio jets
Jul 10, 2015 (SPX)
Cosmic microwave radiation points to invisible 'dark matter', marking the spot where jets of material travel at near light speed, according to an international ...
Stellar Sparklers That Last
Jul 07, 2015 (JPL)
While fireworks only last a short time here on Earth, a bundle of cosmic sparklers in a nearby cluster of stars will be going off for a very long time. NGC 1333...
Astronomers predict fireworks from rare stellar encounter in 2018
Jul 07, 2015 (SPX)
