SUNSET: 
About The LIGO Gravitational-Wave Rumor. . .
Gossip is racing around the physics and astronomy community: has LIGO finally heard its first black-hole merger? Here’s the reality.
"Strongman" Aussie Discovers Dwarf Galaxy
All amateur Michael Sidonio wanted was a pretty astro-image of NGC 253. What he got instead was credit for discovering a rare dwarf galaxy.
Small Galaxies Helped Light Up Universe
Hubble observations confirm that much of the light that broke up the early universe’s hydrogen came from the smallest galaxies.
Is Dark Energy a Chameleon?
A lab experiment has all but nixed one of the theories of dark energy, a mysterious force pushing the universe apart.
Gigantic Protogalaxy in the Cosmic Web
Astronomers have found that a massive filament of gas in the early universe actually seems to be a humongous, galaxy-forming disk.
Dust-poor Early Galaxies
New ALMA observations reveal low levels of dust in nine early galaxies, suggesting astronomers should revise some of their calculations.
Between Galaxies: Lonely Supernovae
Researchers confirm that three solitary stars have gone supernovae in intergalactic space.
An Unusual Star: Wolf-Rayet Nasty 1
Starry cannibalism of Wolf-Rayet Star Nasty 1 may offer clues as to how massive, pre-supernova stars evolve.
Mapping Dark Matter
Two projects are mapping the distribution of dark matter in the universe, probing scales both large and small.
Ancient Galaxies Seen Dying Inside-Out
Astronomers have found massive galaxies 3 billion years after the Big Bang that are dying from the inside out.
Ring-Shaped Spyglass to Early Universe
A rare type of gravitational lens offers astronomers a close look at a young, dusty galaxy manufacturing hundreds of stars a year.
How Slippery Is Dark Matter?
Dozens of galaxy clusters confirm that dark matter particles slip right past each other within messy cluster mergers.
New Dwarf Galaxies Near Milky Way
Astronomers have found a set of new dwarf galaxy candidates near the Milky Way Galaxy, a discovery crucial to understanding dark matter.
Hubble Spots a Lensed Supernova
For the first time, astronomers are watching as a supernova’s light bends around a massive galaxy on its way to Earth.
Dusty Galaxy in the Early Universe
A small galaxy 700 million years after the universe’s birth has a dust reservoir that makes it look like a much older galaxy.
Monster Black Hole in Early Universe
Astronomers have discovered one of the brightest quasars in the early universe. The source, SDSS J010013.02+280225.8 (hereafter J0100+2802), is powered by a supermassive black hole at a redshift of 6.3, meaning that its light left it 12.8 billion years ago.
Planck Upholds Standard Cosmology
The Planck team has finally released its full-mission data, revealing a remarkably detailed view of our universe and our galaxy.
Cosmic Inflation Signal Just Dust
The long-awaited analysis of spiraling polarization patterns called B-modes affirms that these signals, purportedly from the universe’s post-birth inflation, are probably from dust in our galaxy instead.
BICEP's Big Bang Finding Reduced to Dust
Yes, it was too good to be true. The cosmic "discovery of the century" last March has officially blown up. Or will blow up next week when a new analysis of polarization in the cosmic microwave background is officially released. The excitement burst onto the world 10 months ago when…
BOSS: A Ruler to Measure Them All
Amidst the release of a treasure trove of astronomical data, scientists announce the most precise “standard ruler” yet for cosmological distances.
