Gravity may have saved the universe after the Big Bang

November 18, 2014 10:34 am | by Laura Gallagher, Imperial College London | News | Comments

New research by a team of European physicists could explain why the universe did not collapse immediately after the Big Bang. Studies of the Higgs particle have suggested that the production of Higgs particles during the accelerating expansion of the very early universe (inflation) should have led to instability and collapse.

Pulling together the early solar system

November 14, 2014 8:35 am | by Jennifer Chu, MIT News Office | News | Comments

While astronomers have observed the protoplanetary disk evolution throughout our galaxy, the mechanism by which planetary disks evolve at such a rapid rate has eluded scientists for decades. Now researchers have provided the first experimental evidence that our solar system’s protoplanetary disk was shaped by an intense magnetic field that drove a massive amount of gas into the sun within just a few million years.

Telescope effort reveals asteroid’s size for first time

November 11, 2014 10:49 am | by Joe Fohn, Communications Dept., Southwest Research Institute | News | Comments

When the double asteroid Patroclus-Menoetius passed directly in front of a star on the night of Oct. 20, 2014, a team of volunteer astronomers across the U.S. was waiting. Observing the event, known as an occultation, from multiple sites where each observer recorded the precise time the star was obscured, yielded the first accurate determination of the two objects’ size and shape.

Baby photos of a scaled-up solar system

November 11, 2014 8:46 am | by Daniel Stolte, Univ. Relations - Communications, Univ. of Arizona | News | Comments

Scientists at the Univ. of Arizona have discovered what might be the closest thing to "baby photos" of our solar system. A young star called HD 95086 is found to have two dust belts, analogous to the asteroid and Kuiper belts in the solar system, surrounded by a large dust halo that only young planetary systems have. 

Synthetic biology for space exploration

November 10, 2014 9:27 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

Does synthetic biology hold the key to manned space exploration of the moon and Mars? Berkeley Lab researchers have used synthetic biology to produce an inexpensive and reliable microbial-based alternative to the world’s most effective anti-malaria drug, and to develop clean, green and sustainable alternatives to gasoline, diesel and jet fuels. In the future, synthetic biology could also be used to make manned space missions more practical.

Dark matter may be massive

November 4, 2014 2:37 pm | by Case Western Reserve Univ. | News | Comments

The physics community has spent decades searching for and finding no evidence that dark matter is made of tiny exotic particles. Case Western Reserve Univ. theoretical physicists suggest researchers consider looking for candidates more in the ordinary realm and, well, more massive. Dark matter is unseen matter, that, combined with normal matter, could create the gravity that, among other things, prevents spinning galaxies from flying apart.

Eye-catching space technology restoring sight

November 4, 2014 10:58 am | by European Space Agency | News | Comments

Laser surgery to correct eyesight is common practice, but did you know that technology developed for use in space is now commonly used to track the patient's eye and precisely direct the laser scalpel? If you look at a fixed point while tilting or shaking your head, your eyes automatically hold steady, allowing you to see clearly even while moving around. This neat trick of nature is a reflex and we are usually unaware that it even happens.

How a giant impact formed asteroid Vesta’s “belt”

November 4, 2014 8:03 am | by Kevin Stacey, Brown Univ. | News | Comments

When NASA’s Dawn spacecraft visited the asteroid Vesta in 2011, it showed that deep grooves that circle the asteroid’s equator like a cosmic belt were probably caused by a massive impact on Vesta’s south pole. Now, using a super high-speed cannon at NASA’s Ames Research Center, Brown Univ. researchers have shed new light on the violent chain of events deep in Vesta’s interior that formed those surface grooves.
