Astrophysicists report radioactive cobalt in supernova explosion

Posted: 29 Aug 2014 07:34 AM PDT

Astrophysicists have detected the formation of radioactive cobalt during a supernova explosion, lending credence to a corresponding theory of supernova explosions.

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

Posted: 28 Aug 2014 02:00 PM PDT

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.

NASA's Spitzer Space Telescope witnesses asteroid smashup

Posted: 28 Aug 2014 02:01 PM PDT

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.

Astronomy: Radio telescopes settle controversy over distance to Pleiades

Posted: 28 Aug 2014 11:27 AM PDT

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

Red Planet's Climate History uncovered in Unique Meteorite

Posted: 27 Aug 2014 10:15 AM PDT

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

Posted: 27 Aug 2014 10:15 AM PDT

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

Posted: 27 Aug 2014 08:18 AM PDT

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.

Best view yet of merging galaxies in distant universe

Posted: 26 Aug 2014 11:11 AM PDT

Astronomers have obtained the best view yet of a collision between two galaxies when the Universe was only half its current age. To make this observation, the team also enlisted the help of a gravitational lens, a galaxy-size magnifying glass, to reveal otherwise invisible detail.

Measurement at Big Bang conditions confirms lithium problem

Posted: 27 Aug 2014 07:02 AM PDT

The field of astrophysics has a stubborn problem and it's called lithium. The quantities of lithium predicted to have resulted from the Big Bang are not actually present in stars. But the calculations are correct -- a fact which has now been confirmed for the first time.

What lit up the universe?

Posted: 27 Aug 2014 06:21 AM PDT

New research shows we will soon uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built. The study by cosmologists shows how forthcoming astronomical surveys will reveal what lit up the cosmos.

Voyager map details Neptune's strange moon Triton

Posted: 22 Aug 2014 06:35 AM PDT

NASA's Voyager 2 spacecraft gave humanity its first close-up look at Neptune and its moon Triton in the summer of 1989. Like an old film, Voyager's historic footage of Triton has been "restored" and used to construct the best-ever global color map of that strange moon. The map, produced by Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, has also been used to make a movie recreating that historic Voyager encounter, which took place 25 years ago, on August 25, 1989.

Spectacular supernova's mysteries revealed

Posted: 22 Aug 2014 05:39 AM PDT

Astronomers are delving into the mystery of what caused a spectacular supernova in a galaxy 11 million light years away, seen earlier this year. The supernova, a giant explosion of a star and the closest one to the Earth in decades, was discovered earlier this year by chance. These phenomena are extremely important to study because they provide key information about our universe, including how it is expanding and how galaxies evolve.

Electric sparks may alter evolution of lunar soil

Posted: 21 Aug 2014 07:24 AM PDT

The moon appears to be a tranquil place, but new modeling suggests that, over the eons, periodic storms of solar energetic particles may have significantly altered the properties of the soil in the moon's coldest craters through the process of sparking -- a finding that could change our understanding of the evolution of planetary surfaces in the solar system.

Your toothpaste's fluorine formed in the stars

Posted: 21 Aug 2014 07:23 AM PDT

The fluorine that is found in products such as toothpaste was likely formed billions of years ago in now-dead stars of the same type as our sun, according to new research by astronomers.

Why NASA studies the ultraviolet sun

Posted: 20 Aug 2014 03:28 PM PDT

You cannot look at the sun without special filters, and the naked eye cannot perceive certain wavelengths of sunlight. Solar physicists must consequently rely on spacecraft that can observe this invisible light before the atmosphere absorbs it.
