Do extremely reddened quasars extinguish star formation
Nov 16, 2016 (SPX)
Galaxies formed and grew billions of years ago by accumulating gas from their surroundings, or colliding and merging with other young galaxies. These early stag...
Cosmic 'barcode' from distant galaxy confirms nature's constancy
Nov 16, 2016 (SPX)
Researchers from Swinburne University of Technology and the University of Cambridge have confirmed that electromagnetism in a distant galaxy has the same streng...
ASTRI offers affordable telescope with constant angular resolution over wide field of view
Nov 14, 2016 (SPX)
The ASTRI project, led by the Italian National Institute of Astrophysics (INAF), produced the first prototype of a Small Size Telescope (SST) in 2014, now under...
Cosmic Whistle Packs a Surprisingly Energetic Punch
Nov 14, 2016 (SPX)
Penn State University astronomers have discovered that the mysterious "cosmic whistles" known as fast radio bursts can pack a serious punch, in some cases relea...
Gemini: Are All Stars Created Equal
Nov 14, 2016 (SPX)
Astronomers using critical observations from the Gemini Observatory have found the strongest evidence yet that the formation of massive stars follow a path simi...
CTA Prototype Telescope Demonstrates Viability of Novel Design
Nov 14, 2016 (SPX)
In October 2016, the ASTRI telescope prototype, a novel dual-mirror Schwarzschild-Couder telescope design proposed for the Cherenkov Telescope Array (CTA), pass...
NASA Space Telescopes Pinpoint Elusive Brown Dwarf
Nov 11, 2016 (JPL)
In a first-of-its-kind collaboration, NASA's Spitzer and Swift space telescopes joined forces to observe a microlensing event, when a distant star brightens due...
The Super-Kamiokande detector awaits neutrinos from a supernova
Nov 11, 2016 (SPX)
Only three or four supernovas happen in our galaxy every century. These are super-energetic events that release neutrinos at the speed of light. At the Super-Ka...
One of the mysteries of globular clusters
Nov 09, 2016 (SPX)
Globular clusters are swarms of about a million stars bound together by their gravitational field and distributed roughly spherically, which have formed from a ...
New Theory of Gravity Might Explain Dark Matter
Nov 09, 2016 (SPX)
A new theory of gravity might explain the curious motions of stars in galaxies. Emergent gravity, as the new theory is called, predicts the exact same deviation...
The birth of massive stars is accompanied by strong luminosity bursts
Nov 09, 2016 (SPX)
The birth of massive stars is still a mystery to us, because these stars are embedded in an extremely dense medium of gas and dust, says Rolf Kuiper, the leader...
Tsunami of stars and gas produces dazzling eye-shaped feature in galaxy
Nov 08, 2016 (SPX)
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a tsunami of stars and gas that is crashing midway through the disk of...
Hubble takes flight with the toucan and the cluster
Nov 08, 2016 (SPX)
It may be famous for hosting spectacular sights such as the Tucana Dwarf Galaxy and 47 Tucanae (heic1510), the second brightest globular cluster in the night sk...
Pillars of destruction
Nov 04, 2016 (SPX)
The spires and pillars in the new images of the Carina Nebula are vast clouds of dust and gas within a hub of star formation about 7500 light-years away. The pi...
Lithium mostly comes from supernovas
Nov 04, 2016 (SPX)
Lithium, the lightest solid element in existence, plays an important role in our lives, both at the biological and the technological level. Like the majority of...
Carina Nebula Blasted by Brilliant Nearby Stars
Nov 04, 2016 (SPX)
Spectacular new observations of vast pillar-like structures within the Carina Nebula have been made using the MUSE instrument on ESO's Very Large Telescope. The...
Supercomputer comes up with a profile of dark matter
Nov 04, 2016 (SPX)
In the search for the mysterious dark matter, physicists have used elaborate computer calculations to come up with an outline of the particles of this unknown f...
Cosmic-ray detector finds possible crack in Earth's magnetic shield
Nov 03, 2016 (UPI)
The world's largest, most sensitive cosmic-ray detector has identified a potential crack in Earth's magnetic field. The weakness was revealed by a burst of gala...
Weakness is good when controlling light
Nov 02, 2016 (SPX)
It's a paradox that has long vexed researchers in the field of optics. To control a light source, another light source that uses as much energy - if not more - ...
Physicists Leapfrog Accelerators with Ultrahigh Energy Cosmic Rays
Nov 02, 2016 (SPX)
An international team of physicists has developed a pioneering approach to using Ultrahigh Energy Cosmic Rays (UHECRs) - the highest energy particles in nature ...
