NASA's Spitzer Space Telescope witnesses asteroid smashup

Science Daily - Thu, 08/28/2014 - 17:01
NASA's Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets.

Researchers use NASA and other data to look into the heart of a solar storm

Science Daily - Thu, 08/28/2014 - 17:00
Scientists found that the CME contained a rare piece of dense solar filament material. This filament coupled with an unusually fast speed led to the large amount of solar material observed.

Astronomy: Radio telescopes settle controversy over distance to Pleiades

Science Daily - Thu, 08/28/2014 - 14:27
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.

Red Planet's climate history uncovered in unique Martian meteorite

Science Daily - Wed, 08/27/2014 - 13:15
Was Mars -- now a cold, dry place -- once a warm, wet planet that sustained life? Research underway may one day answer those questions -- and perhaps even help pave the way for future colonization of the Red Planet. By analyzing the chemical clues locked inside an ancient Martian meteorite known as Black Beauty, scientists are revealing the story of Mars’ ancient, and sometimes startling, climate history.

Early growth of giant galaxy, just 3 billion years after the Big Bang, revealed

Science Daily - Wed, 08/27/2014 - 13:15
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 of data from several space telescopes. Hubble photographed the emerging galaxy as it looked 11 billion years ago, just 3 billion years after the birth of our universe in the big bang.

Orion rocks! Pebble-size particles may jump-start planet formation

Science Daily - Wed, 08/27/2014 - 11:18
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.
