X-Ray Jets from Galaxies

(PhysOrg.com) -- Some dramatic galaxies eject gigantic, collimated jets of ionized gas millions of light-years long, powered by the massive black holes at their centers. The ionized jets are detected at radio wavelengths, ...

Where are stars made? NASA's Spitzer spies a hot spot

The nebula known as W51 is one of the most active star-forming regions in the Milky Way galaxy. First identified in 1958 by radio telescopes, it makes a rich cosmic tapestry in this image from NASA's recently retired Spitzer ...

A violent, complex scene of colliding galaxy clusters

Astronomers using the Karl G. Jansky Very Large Array (VLA) and the Chandra X-Ray Observatory have produced a spectacular image revealing new details of violent collisions involving at least four clusters of galaxies. Combined ...

Zooming in on the origins of fast radio bursts

Astronomers have peered into the home galaxies of fast radio bursts, ruling out supermassive black holes as a cause and bringing us a step closer to understanding the origins of these mysterious signals from outer space.

The hidden galaxy in the zone of avoidance

There are some places astronomers dare not tread. One of the prime places is beyond the disk of our own galaxy where the numerous stars and clouds of dust along the line of sight make observations messy to say the least. ...

Untangling a knot of galaxy clusters

Astronomers have captured a spectacular, ongoing collision between at least three galaxy clusters. Data from NASA's Chandra X-ray Observatory, ESA's (European Space Agency's) XMM-Newton, and a trio of radio telescopes is ...
