A Tour of VLA J2130+12
A Tour of VLA J2130+12
Astronomers have found many black holes both here in our Milky Way galaxy and beyond. (2016-06-27)


GB 1428+4217 in 60 Seconds

View/Listen
Narrator (April Hobart, CXC): The most distant jet in X-ray light has been discovered using data from NASA's Chandra X-ray Observatory. This jet was found in the quasar known as GB 1428+4217, or GB 1428 for short. How does GB 1428 make its jet? When giant black holes pull in material at a very rapid rate, large amounts of energy are released. This results in the production of intense radiation and beams of high-energy particles that blast away from the black hole at nearly the speed of light. Astronomers call these beams of particles "jets". At a distance of 12.4 billion years from Earth, the jet in GB 1428 gives astronomers a glimpse into the explosive activity associated with the growth of giant black holes in the early Universe.
