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.

The Mystery of the Star That Wasn't There
In the 1970s, astronomers discovered a mysterious source of gamma rays that, 50 years later, still hasn’t revealed all of its secrets.

The Spiders That Turn Stars into Planets
Neutron stars, are some of the most extreme phenomenon in the universe. It's doubly so for a subset known as pulsars. Some are spinning so fast, and are so massive, that astronomers aren't entirely sure how they got to be that way. One...

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...

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...

How An Extreme New Star Could Change All Cosmology
A new white dwarf has been discovered (poetically named: ZTF J1901+1458) that’s doing some stuff that no white dwarf should ever be able to do. In fact, it has multiple properties that are so extreme that it almost certainly did NOT form...

Pulsar Starquakes Make Fast Radio Bursts? + Challenge Winners! | Space Time | PBS Digital Studios
Fast Radio Bursts were puzzling physicist for quite some time. They were thought to be the result of large cataclysmic events such as supernovae, but this theory was proven wrong when it was discovered that they could repeat themselves....

What If Dark Matter Is Just Black Holes?
It may be that for every star in the universe there are billions of microscopic black holes streaming through the solar system, the planet, even our bodies every second. Sounds horrible - but hey, at least we’d have explained dark matter.
