New image captures galaxy cluster emerging from cosmic web

The tumultuous evolution of a galaxy cluster captured close to its formation in the cosmic web

An international team of astronomers using the National Science Foundation’s Green Bank Telescope (GBT) in Green Bank, West Virginia, and the NASA’s Chandra X-ray Observatory have captured a snapshot of a massive galaxy cluster, very close to the epoch when it began to emerge from the cosmic web.


Massive Invisible Galactic Structure is Discovered – By Accident

Incredibly sensitive spectral observations from the Green Bank Telescope discover previously unknown huge Galactic structure

When it comes to the Universe, there is more than meets the eye. Astronomers using the National Science Foundation’s Green Bank Telescope (GBT) have discovered a massive, previously unknown structure in our Galaxy. This discovery was so unexpected, additional observations were taken using the Green Bank Observatory’s 20-meter Telescope to confirm the data. 


Green Pea Galaxies: Live Short and Prosper

These nearby nurseries shed light on the early days of the Universe

Looking up at the night’s sky, twinkling with celestial objects, do you ever dream of discovering something new? How about something that sheds light on the early days of the Universe? A decade ago, citizen scientists, in the Galaxy Zoo project, helped astronomers discover a new and important class of galaxies, the Green Peas.
