Black Hole Burp
Our Milky Way galaxy is a sprawling collection of gas, dust, and hundreds of billions of stars. In the very center of the galaxy lies a hidden monster: a black hole. This is a super massive black hole with four million times the Sun’s mass. Most of the time it is sitting there being black and holey. But sometimes it gobbles a little snack. As a result it let out a cosmic-sized belch. Like it did in July 2012:

Neutron stars are supermassive bodies that behave in a number of unique ways. German animation studio Kurzgesagt explains their "out of this world" properties, and answers why neutron stars are so fascinating to astronomers despite being relatively tiny.

Have a listen to some famous pulsars

Interactive graphic showing every known pulsar. Awesome!
http://astro.berkeley.edu/~ishivvers/pulsars.html
This map shows the position of almost every radio pulsar known to modern researchers. The map is an equirectangular projection of the night sky in galactic coordinates, showing the entire sky as visible from Earth with our Milky Way galaxy running through the middle. The size of each circle illustrates the relative brightness (as seen from Earth) for each pulsar, and each circle emits pulses at the true frequency of the pulsar. The slider on top of the page lets you move through space, exploring different distances from Earth. Look to the counter in the top right to see what distance range is currently shown. Click on any pulsar to learn more about that object. |

Journey to a black hole Interactive site where you can search the sky for black holes using different telescopes and take a virtual trip to see a black hole up close. |
How fast do black holes spin? 84% the *speed of light*. That’s 251,825,665 meters per second
