What are Years... and the Galactic Supermassive Black Hole!
It's leap year time... so what are years, anyway? And what do they have to do with the supermassive black hole in the core of the milky way?

Is JWST Living Up to the Hype?
The James Webb Space Telescope is the most ambitious space observatory ever launched, and nobody hyped it more than us. So is it putting in work? Oh, boy, yes. Yes it is.

Holes In Space That Aren't Black | Compilation
We’ve talked a lot about black holes, but there are other kinds of space holes out there that deserve some time in the spotlight!

Five Of The Biggest, Baddest Supernova Varieties
Supernovae are only rare to the passive stargazer, but if you’re an astronomer studying them, you get to see some of the most brilliant explosions in the universe. Here are five of the most significant supernovae known to science.

This Year in Space News (That Isn't JWST)
If you’ve been distracted looking at the amazing photos The James Webb Space Telescope has taken, not to worry. Here are three other stellar stories from the last year of space science!

How Stars Destroy Each Other
Our galaxy is full of dysfunctional stellar relationships. With more than half of all stars existing in binary orbits, it’s inevitable that many stellar remnants will end up in parasitic spirals with their partners. Today we’re going to...

Do Black Holes Create New Universes?
Physicists have been struggling for some time to figure out why our universe is so comfy. Why, for example, are the fundamental constants - like the mass of the electron or the strength of the forces - just right for the emergence of...

NEW DISCOVERY About Supermassive Black Holes Explained!
Astrophysicists have discovered a black hole that for millions of years has been blasting vast particle beams in opposite directions across the sky. And has recently swiveled to point its one of these jets directly at us. Is this an...

How Black Holes Spin Space Time
If there’s one thing cooler than a black hole it’s a rotating black hole. Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes. Black holes are self-sustaining holes in the...

Will Wormholes Allow Fast Interstellar Travel?
From Stargate to Interstellar, wormholes are our favorite method for traveling across fictional universes. But they are also a very serious field of study for some of our greatest minds over the last century. So what’s the holdup? When...

How The Penrose Singularity Theorem Predicts The End of Space Time
The Nobel prize in physics this year went to black holes. Generally speaking. Specifically, it was shared by the astronomers who revealed to us the Milky Way’s central black hole and by Roger Penrose, who proved that in general...

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...

Building Black Holes in a Lab
Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we...

The Holographic Universe Explained
The holographic principle emerged from many subtle clues – clues discovered over decades of theoretical exploration of the universe. Over the past several months on Space Time, we’ve seen those close clues, and we’ve built a the...

What If (Tiny) Black Holes Are Everywhere?
It’s fair to say that black holes may be the scariest objects in the universe. Happily for us, the nearest is probably many light-years away. Unless of course, Planck relics are a thing - in which case they might be literally everywhere.

The Boundary Between Black Holes & Neutron Stars
When we detected the very first gravitational wave, a new window was opened to the mysteries of the universe. We knew we’d see things previously thought impossible. And we just did - an object on the boundary between neutron stars and...

Could The Universe Be Inside A Black Hole?
What is inside a black hole? Inevitable crushing doom? Gateways to other universes? Weird, multidimensional libraries? If you’ve ever wanted to know then you might be in luck - Some physicists have argued that you’re inside one right now.
