A team of astronomers has discovered what appears to be a grand exodus of more than 100 hydrogen clouds streaming away from the center of the Milky Way and heading into intergalactic space.(more…)

Green Bank, January 10, 2018 – Using two of the world’s largest radio telescopes, an international team of astronomers have gained new insight into the extreme home of a mysterious source of cosmic radio bursts. The discovery suggests that the source of the radio emission lies near a massive black hole or within an extremely powerful nebula, and may help shed light on what is causing these strange bursts.
The team presented their findings at the American Astronomical Society’s winter meeting (#AAS231) in Washington, D.C. The results are presented in the journal Nature.

Have you heard?! This summer, you have the chance to experience a spectacular stellar event! On August 21, the star that brings us spring flowers, warm days by the pool, and the northern lights, a.k.a. our Sun, will be eclipsed by the Moon. Want to see it? You’re invited!(more…)
A team of astronomers has unveiled a striking new image of the Orion Molecular Cloud (OMC) – a bustling stellar nursery teeming with bright, young stars and dazzling regions of hot, glowing gas.
The researchers used the National Science Foundation’s (NSF) Green Bank Telescope (GBT) in West Virginia to study a 50 light-year long filament of star-forming gas that is wending its way through the northern portion of the OMC known as Orion A.
The GBT rendered this image by detecting the faint radio signals naturally emitted by molecules of ammonia that suffuse interstellar clouds. Scientists study these molecules to trace the motion and temperature of vast swaths of star-forming gas.
These observations are part of the first data release from a large campaign known as the Green Bank Ammonia Survey. Its purpose is to map all the star-forming ammonia and other key tracer molecules in a massive structure known as the Gould Belt.
The Gould Belt is an extended ribbon of bright, massive stars stretching about 3,000 light-years in an arc across the sky. This first release covers four distinct Gould Belt clouds, one located in Taurus, one in Perseus, one in Ophiuchus, and Orion A North in Orion.
