Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered some incredibly useful materials along the way. But the elements at the current end of the table are...

Neutron stars aren't dark matter--we figured that out a while ago. But new research is telling us that they may be dark matter factories. They may produce the exotic axion, one of the most popular dark matter candidates.

Not long after the supernova of 1604, the telescope was invented. But astronomers would have to wait nearly FOUR CENTURIES to witness the next supernova that was visible to the naked eye. It was 1987, and a blue supergiant in the Large...

This video is about the differences between the corpses or final degenerate dense star forms that dead stars take: black holes, neutron stars, and white dwarfs. The main distinguishing features between them are the mass cutoffs...

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.

In the 1970s, astronomers discovered a mysterious source of gamma rays that, 50 years later, still hasn’t revealed all of its secrets.

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...

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...

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...

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...

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...

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....

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.

Precious metals like gold, silver, platinum, and rhodium are expensive because they're rare in Earth's crust. But are they rare in the universe? Why is it so hard to make some of the chemical elements? Where do heavy metals come from,...

We’ve traveled to lots of weird places on this show - from the interiors of black holes to the time before the big bang. But today I want to take you on a journey to what has got to be the weirdest place in the modern universe - a place...

There are still several fascinating mysteries of our universe unsolved by scientists even after decades and even centuries of research! Join Olivia Gordon for a new episode of SciShow and learn about these seven weird phenomena that...

Black holes have mystified physicists for decades, but with the help of quantum mechanics, we are beginning to make serious progress in understanding these strange objects. This week on Space Time, Matt dives deeper into the physical...

Even science can't yet explain these 7 extremely cool, weird phenomena in the universe, despite decades or even centuries of research.

You might think we've already found every kind of star by now, but astronomers think there are more that should hypothetically exist!

Our favorite fast radio burst, FRB 121102, brings us one step closer to understanding its source, and astronomers have a new theoretical upper limit for star masses.

SciShow Space shares the latest news from around the universe, including the first observation of a star-within-a-star, and the debut image from the newest telescope to be enlisted in the hunt for alien worlds.

A new study provides mathematical evidence that dark matter could be much older than we thought and we've found a weird glitch in a neutron star.

In the aftermath of a 8 – 20 solar mass star’s demise we find a weird little object known as a neutron star. Neutrons stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars,...

We’ve detected seismic activity all around the solar system, from earthquakes to moonquakes, marsquakes to venusquakes. But the most dramatic quakes we know of actually happen on stars!
