Exploring Black Holes: Part 2

The Care and Feeding of Black Holes

How intrinsically invisible objects become the brightest things in the universe

The quasar poetically known as GB 1428 in visible, radio, and X-ray light. This object is more than 12 billion light-years away but is bright enough to be seen from Earth. That’s because it’s powered by a supermassive black hole. X-ray: NASA/CXC/NRC/C.Cheung et al; Optical: NASA/STScI; Radio: NSF/NRAO/VLA.
