Was the Milky Way a Quasar?
The Milky Way galaxy is relatively calm by the destructive standards of the rest of the Universe, and compared to its own very violent past. But just recently we discovered that its violent past was much more recent than we thought - and...

Gravitational Wave Background Discovered?
It was pretty impressive when LIGO detected gravitational waves from colliding black holes. Well we’ve just taken that to the next level with a galaxy-spanning gravitational wave detector that may have detected a foundational element of...

The Alchemy of Neutron Star Collisions
Carl Sagan’s famous words: “We are star stuff” refers to a mind-blowing idea – that most atomic nuclei in our bodies were created in the nuclear furnace and the explosive deaths of stars that lived in the ancient universe. In recent...

The Future of Gravitational Waves
On September 14th, 2015 LIGO announced the first detection of a gravitational wave. This was hailed at the time as the dawn of gravitational wave astronomy. However that’s only true if the we ever detect another gravitational wave. Now...

The Black Hole Tipping Point
This video is about the Schwarzschild radius of a black hole, (its "event horizon"), and how much mass and density is required to reach the point of no return where an object like a star, neutron star, red giant, etc will collapse into a...

How Will the Universe End?
We live in an unusual age - the age when the stars still shine. We should count ourselves lucky - nearly all of future history will be dark. But events will still unfold in that long, cooling darkness, and civilizations may endure. So...

Using Stars to See Gravitational Waves
Now that gravitational waves are definitely a thing, it's time to think about some of the crazy things we can figure out with them. In some cases we're going to need a gravitational wave observatory - in fact, we've already built one.
