"Proof of Inflationary Universe" to be Announced
Rumors are flying that the long-sought "smoking gun" for inflation has been found in polarization patterns in the cosmic microwave background. If so, it would confirm the inflation theory for how and why the Big Bang happened.
Planets Form With Magnetic Storms
Astronomers might have solved an outstanding mystery of why forming planetary systems emit more infrared light than expected. The key lies with gas and dust suspended in giant magnetic loops.
Asteroid to Black Out Bright Star Regulus
Bright Regulus will dramatically snap out of view behind a faint asteroid for several seconds very late Wednesday night for well-placed viewers — if the sky clears!!

Name a Mars Crater with Uwingu
Here’s what you need to know about a new fundraising venture, the race to name 500,000 craters on Uwingu’s Mars map.
A Chaotic Planet-Forming Disk
A new map of Beta Pictoris reveals an asymmetric clump of carbon monoxide likely produced in cometary collisions. It provides a rare glimpse at the chaotic birth of a planetary system.
Black Hole Spins Super Fast
X-ray observations and cosmic coincidence unveil the details of a distant supermassive black hole. The result could be a first step in expanding our understanding of how black holes have beefed themselves up over the last several billion years.
Satellite Lost and Found in Space
SkyCube, a crowd-funded nanosatellite built to engage the public in space exploration, has been deployed from the International Space Station. Now its creators are anxiously waiting to establish two-way contact.
Fingerprinting the Circumgalactic Medium
A new study finds the space surrounding dwarf galaxies in the nearby universe to be shockingly pristine.
Tour March's Sky! | March 1st, 2014
A stunning array awaits you overhead once the Sun sets. Brilliant Sirius, along with Procyon, Betelgeuse, and even-brighter Jupiter, form a giant diamond in the evening sky.
New Record for Oldest Earth Rock
No rocks on Earth are as old as the planet itself. But a tiny grain of zircon from Western Australia shows that <em>terra firma</em> existed within about 160 million years of the solar system's formation.
Black Hole Ate Too Much
A stellar-mass black hole in the iconic galaxy M83 seems to have kept eating long after it should have stopped. If true, the discovery could have implications for how much black holes can affect their environments.
Rocky Encounter with Stellar Lighthouse
Asteroid debris might be bombarding a radio pulsar in the constellation Puppis.
Kepler's Planets by the Hundreds
Old data from NASA’s crippled Kepler space telescope has yielded a new windfall of confirmed exoplanets, nearly doubling the number tallied since 1992.
Catch a Comet Buzzing Earth
On Thursday, May 29th, Comet 209P/LINEAR will pass just 5 million miles (8 million km) from Earth, one of the closest comet approaches in history.
