Betelgeuse spinning much faster than expected; may have swallowed a star
Dec 21, 2016 (SPX)
Astronomer J. Craig Wheeler of The University of Texas at Austin thinks that Betelgeuse, the bright red star marking the shoulder of Orion, the hunter, may have...
Pan-STARRS releases catalogue of 3 billion astronomical sources
Dec 21, 2016 (SPX)
The Pan-STARRS project, including astronomers at the Max Planck Institutes for Astronomy in Heidelberg and for Extraterrestrial Physics in Garching, is publicly...
It's a cosmic winter wonderland at NGC 6357
Dec 21, 2016 (SPX)
Although there are no seasons in space, this cosmic vista invokes thoughts of a frosty winter landscape. It is, in fact, a region called NGC 6357 where radiatio...
Mystery of super flash solved
Dec 16, 2016 (SPX)
When astronomers and astrophysicists observe flashes of light in the dark sky, they assume they have seen a supernova. Possibly a star has burnt up its supply o...
Newly formed stars shoot out powerful whirlwinds
Dec 16, 2016 (SPX)
Researchers from the Niels Bohr Institute have used the ALMA telescopes to observe the early stages in the formation of a new solar system. For the first time t...
Young, thin and hyperactive: That's what outlier galaxies look like
Dec 14, 2016 (SPX)
If we put the galaxies for which we have the relevant data into a graph relating the mass of stars in each galaxy with the star formation rate of that galaxy, m...
A new light on stellar death
Dec 13, 2016 (SPX)
Back in 2015 when astronomers discovered an intense flare in a distant galaxy, they considered it the brightest supernova ever observed. Now, UC Santa Barbara a...
Hubble catches a transformation in the Virgo constellation
Dec 13, 2016 (SPX)
The constellation of Virgo (The Virgin) is especially rich in galaxies, due in part to the presence of a massive and gravitationally-bound collection of over 13...
A nano-roundabout for light
Dec 12, 2016 (SPX)
Just like in normal road traffic, crossings are indispensable in optical signal processing. In order to avoid collisions, a clear traffic rule is required. A ne...
Home computers discover a record-breaking pulsar-neutron star system
Dec 09, 2016 (SPX)
Almost 25,000 light years away, two dead stars, each more massive than our Sun, but only 20 kilometers in diameter, orbit one another in less than five hours. T...
Amateur astronomer helps uncover secrets of unique pulsar binary system
Dec 09, 2016 (SPX)
A professional astrophysicist and an amateur astronomer have teamed up to reveal surprising details about an unusual millisecond pulsar (MSP) binary system comp...
'Hyper-starburst' galaxy churns out stars, clues to universe's evolution
Dec 09, 2016 (SPX)
A recently discovered galaxy is undergoing an extraordinary boom of stellar construction, revealed by a group of astronomers led by University of Florida gradua...
Dark matter may be smoother than expected
Dec 09, 2016 (SPX)
Hendrik Hildebrandt from the Argelander-Institut fur Astronomie in Bonn, Germany and Massimo Viola from the Leiden Observatory in the Netherlands led a team of ...
Will Earth still exist 5 billion years from now
Dec 09, 2016 (SPX)
What will happen to Earth when, in a few billion years' time, the Sun is a hundred times bigger than it is today? Using the most powerful radio telescope in the...
Dark matter may be more smoothly distributed throughout cosmos
Dec 07, 2016 (UPI)
New analysis of a phenomenon known as cosmic shear suggests dark matter is less dense and more evenly -- or smoothly -- distributed throughout space. The revela...
Second-generation stars identified, giving clues about their predecessors
Dec 07, 2016 (SPX)
University of Notre Dame astronomers have identified what they believe to be the second generation of stars, shedding light on the nature of the universe's firs...
Where giant galaxies are born
Dec 06, 2016 (SPX)
An international team of scientists, with IAC participation, has discovered that the biggest galaxies in the universe develop in cosmic clouds of cold gas. This...
UCLA astronomers watch star clusters spewing out dust
Dec 02, 2016 (SPX)
Galaxies are often thought of as sparkling with stars, but they also contain gas and dust. Now, a team led by UCLA astronomers has used new data to show that st...
Tangled threads weave through cosmic oddity
Dec 02, 2016 (SPX)
New observations from the NASA/ESA Hubble Space Telescope have revealed the intricate structure of the galaxy NGC 4696 in greater detail than ever before. The e...
Cool Theory on Galaxy Formation
Dec 01, 2016 (SPX)
Giant galaxies may grow from cold gas that condenses as stars rather than forming in hot, violent mergers. The surprise finding was made with CSIRO and US radio...
