Quasars and Active Galactic Nuclei (#AGN)
-
by c_cld
Join Hubble scientists for a live Hubble Hangout discussion at 3pm EDT on Thurs., April 2, to learn even more. Visit: http://hbbl.us/y6c .
Most galaxies have at their cores a supermassive black hole hundreds of millions of times the mass of our Sun. They emit powerful ultraviolet radiation from the supermassive black hole at the core of the host galaxy.
The most active of these galaxy cores are called quasars, where infalling material is heated to a point where a brilliant searchlight shines into deep space. The beam is produced by a disk of glowing, superheated gas encircling the black hole.
Please join +Tony Darnell Dr.+Carol Christian and +Scott Lewis as they discuss some fascinating new observations of quasars made by the Hubble Space Telescope
