11:25 AM | Astrophysicists report radioactive cobalt in supernova explosion
Astrophysicists have detected the formation of radioactive cobalt during a supernova explosion, lending credence to a corresponding theory of supernova explosions. The article’s main author, Yevgeny Churazov (Space Research Institute of the Russian Academy of Sciences), together with his co-authors, including Sergei Sazonov of the Space Research Institute and MIPT, reported the results of their …

11:22 AM | Astronomy: Radio telescopes settle controversy over distance to Pleiades
A worldwide network of radio telescopes measured the distance to the famous star cluster the Pleiades to an accuracy within 1 percent. The result resolved a controversy raised by a satellite’s measurement that now is shown to be wrong. The incorrect measurement had challenged standard models of star formation and evolution. The astronomers studied the …

11:08 AM | Detecting neutrinos, physicists look into the heart of the sun
Using one of the most sensitive neutrino detectors on the planet, physicists have directly detected neutrinos created by the ‘keystone’ proton-proton fusion process going on at the sun’s core for the first time. The pp reaction is the first step of a reaction sequence responsible for about 99 percent of the Sun’s power, Pocar explains. …

11:06 AM | Early growth of giant galaxy, just 3 billion years after the Big Bang, revealed
The birth of massive galaxies, according to galaxy formation theories, begins with the buildup of a dense, compact core that is ablaze with the glow of millions of newly formed stars. Evidence of this early construction phase, however, has eluded astronomers — until now. Astronomers identified a dense galactic core, dubbed “Sparky,” using a combination …

10:51 AM | Orion Nebula may be brimming with pebble-size particles
Astronomers have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles — planetary building blocks 100 to 1,000 times larger than the dust grains typically found around protostars. Astronomers using the National Science Foundation’s (NSF) Green Bank Telescope (GBT) have discovered that filaments of star-forming gas near the …

4:45 PM | Newly Announced Super-Earth May Be The Closest Exoplanet Discovered Yet
Gliese15Ab is a newly discovered planet roughly five times the mass of Earth. Researchers aren't sure what the planet's atmosphere is like, and it's close enough to its parent star to heat it past the boiling point of water. But the most interesting thing about Gliese 15Ab isn't how close it is to its star. It's how close it is to us.Read more...

10:11 PM | Why Are Stars Star-Shaped? Great new video from MinutePhysics...
Why Are Stars Star-Shaped? Great new video from MinutePhysics that asks why we draw stars as star-shapes, when they’re really just spherical orbs of superheated plasma (and those are much easier to draw, by the way). We know that stars twinkle because of the distortion caused by our atmosphere miles above your head, but that’s not what gives them their apparent star shape. If that were the case, then why do Hubble images also flare out? Unless J.J. Abrams works for NASA or […]

4:20 PM | What Lit Up The Universe? Astronomers May Be On The Brink Of An Answer
Most scientists can see, hear, smell, touch or even taste their research. But astronomers can only study light — photons traveling billions of light-years across the cosmos before getting scooped up by an array of radio dishes or a single parabolic mirror orbiting the Earth.Read more...

8:07 AM | Witnessing the early growth of a giant : First ever sighting of galaxy core formation
Astronomers have uncovered for the first time the earliest stages of a massive galaxy forming in the young Universe. The discovery was made possible through combining observations from the NASA/ESA Hubble Space Telescope, NASA’s Spitzer Space Telescope, ESA’s Herschel Space Observatory, and the W.M. Keck Observatory in Hawaii. The growing galaxy core is blazing with…Read more →

2:57 AM | New Evidence that We Live in a Space Bubble
Many people enjoy talking about their neighborhood, and how well they've come to know it. But do you know much about the "neighborhood" that our Sun and its planets hang out in? New evidence from an instrument launched aboard a NASA rocket has confirmed that our cosmic neighborhood really is a big bubble. We have known for some time that our solar system sits inside a region which is emptier than the typical neighborhood in the Milky Way Galaxy. This "Local Bubble" (as it is called) […]
