Today Phil follows up last week’s look at the death of low mass stars with what comes next: a white dwarf. White dwarfs are incredibly hot and dense objects roughly the size of Earth. They also can form planetary nebulae: huge,...

Asteroseismology allows scientists to explore stars with sound. It can help them figure out what a star is burning and even help pin down the age of stars!

Hank gives us an inclusive overview of how everything in the universe is thought to have begun, and how cosmologists predict it will all come to an end. Now get happy!

Scientists have found a star that spins so fast that it can almost complete a full rotation by the time it takes you to finish reading this episode description.

The first full-color images from the James Webb Space Telescope are finally here! Let's take a look, talk about what we're seeing, and compare them to the most detailed version of these images we had before.

Double stars are stars that appear to be near each other in the sky, but if they’re gravitationally bound together we call them binary stars. Many stars are actually part of binary or multiple systems. If they are close enough together...

Today we are talking about the life -- and death -- of stars. Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives. They fuse hydrogen into...

So you know what a star is, right? Well, if you don't, you should. We've talked about that big one in the sky a few times: The Sun! But there are a lot of bright dots in the night sky and not all of them are stars. Today, let's play a...

Exoplanets have taught us a lot more about planets than our solar system could ever teach us, from what happens when they’re born, to what happens when their stars die.

Over just 20 years, the Stingray nebula has become anywhere from 29 to 900 times dimmer! It could teach us a ton about how nebulas evolve over time, and what happens when everything is going a lot faster than expected.

What exactly will happen when the sun dies?

The universe, shortly after the big bang only consisted of the lightest elements, Hydrogen, Helium Lithium, and some isotopes. But today we have elements on earth as heavy as Californium, element 98 on the periodic...

In around a billion years, increases in the sun’s energy output will ensure oxygen levels on Earth drop to levels that cannot sustain complex life, so we should build a giant thruster to shift the planet’s orbit.

Astronomers have discovered a red giant 3,500 light-years from Earth that could be one of the oldest stars in the cosmos.

5 of the most unusual, amazing and interesting stars we've discovered in our universe. Red giants, supernovas, hybrid stars, orbiting binaries, large stars, old stars, small stars, we've discovered thousands of stars within our milky way...
