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.

Revealing the Microscopic Mechanisms in Perovskite Solar Cells

In just a few years, researchers have achieved remarkable power conversion efficiency with materials with perovskite crystal structure, comparable with the best photovoltaic materials available. Now, researchers have revealed the physics for how an important component of a perovskite solar cell works -- a finding that could lead to improved solar cells or even newer and better materials. They describe their experiments in this week's issue of the journal Applied Physics Letters.

Less Radiation in Inner Van Allen Belt Than Previously Believed

VABprobes-NASA.jpeg

The inner Van Allen belt has less radiation than previously believed, according to a recent study in the Journal of Geophysical Research. Observations from NASA’s Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.
