NASA Announces Astronomy and Astrophysics Fellows for 2017

g1713a-800x600.jpg

NASA has selected 28 Fellows for its prestigious Einstein, Hubble, and Sagan fellowships. Each post-doctoral fellowship provides three years of support to awardees to pursue independent research in astronomy and astrophysics. The new Fellows begin their programs in the fall of 2017 at a host university or research center of their choosing in the United States.

Understanding Predictability and Randomness by Digging in the Dirt

When tilling soil, the blade of the tool cuts through dirt, loosening it in preparation for seeding. The dirt granules are pushed aside in a way that looks random -- but might not be. Now, researchers have found a way to distinguish whether such a process is truly random, or is actually deterministic -- which can lead to deeper understanding and the ability to control the process. They describe the analysis in the journal Chaos.

The Power of One: Single Crystals Provide Clarity

CanfieldSolutionGrowth2_1.jpg

When it comes to creating new materials, single crystals play an important role in presenting a clearer picture of a material’s intrinsic properties. A typical material will be comprised of lots of smaller crystals and the grain boundaries between these crystals can act as impediments, affecting properties such as electrical or thermal resistance.

From the Room Next Door to the Next Planet Over

The new Albert Chadwick Research Room inside the Roberts Proton Therapy Center is no ordinary laboratory space. In fact, there’s nothing else quite like it anywhere else in the United States, and whether it’s treating patients with cancer or helping NASA with its plans to send astronauts to Mars, the discoveries that could propel scientists forward will happen right here.

Milky Way-Like Galaxies in Early Universe Embedded in 'Super Halos'

Using ALMA, astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only eight percent of its current age. These progenitors of today’s giant spiral galaxies are surrounded by "super halos" of hydrogen gas that extend many hundreds-of-thousands of light-years beyond their dusty, star-filled disks.

Gravitational Wave Kicks Monster Black Hole Out of Galactic Core

An international team of astronomers using NASA's Hubble Space Telescope have uncovered a supermassive black hole that has been propelled out of the center of the distant galaxy 3C 186. The black hole was most likely ejected by the power of gravitational waves.

New Study Maps Space Dust in 3-D

A new Berkeley Lab-led study provides detailed 3-D views of space dust in the Milky Way, which could help us understand the properties of this dust and how it affects views of distant objects.

The Future of Astronomy: ALMA and the Next Generation VLA – A Newswise Live Expert Panel Discussion

ALMA_potw_eso_130116.jpg

Two of the most iconic telescopes on Earth – the Very Large Array, or VLA as its known, and ALMA, the trailblazing Atacama Large Millimeter/submillimeter Array – are helping us understand our cosmic origins, but their stories are just beginning. New technology and future expansions will greatly enhance their abilities, revealing never-before-seen details of the cosmos. Two astronomers explain the latest discoveries and future upgrades for these powerful instruments.
