ID2299, a galaxy 13.8 billion light years away, died far too young.

Meet TYC 7037-89-1, a six-star solar system. Astrophysicist Paul M. Sutter explains this stellar surprise discovery.

Sometimes when you want to go out, you want to go out with a bang.

All planets with evidence of life please take a step forward. Not so fast, Venus.

Mars is the ultimate off-the-grid experience--far grittier, far harder, and far… redder than even the most remote locations on planet Earth. Let’s break down some of the challenges that people will have to face in order to survive and thrive on our neighbor in the solar system.

Long ago, our universe was without stars. When that first generation ignited, it completely transformed the cosmos, ripping away the veil of neutral gas that had persisted for hundreds of millions of years. This process, called reionization, is largely mysterious to astronomers. But new research is revealing that the smallest of galaxies may have played the biggest of roles.

All Stars die. Some stars go out with a bang. Some stars go out with a big bang — a supernova. And some stars are capable of something so spectacular, so rare, we don't even have a name for it yet.

A vocal minority believes that the moon landing was all an elaborate hoax filmed on a sound stage in Hollywood, but it's no hoax. Here's why...

Okay, stars die in all sorts of interesting and cosmically expressive ways (except the red dwarf stars, who just sort of…stop).

Every star you see in the sky, including the sun, will someday die. It’s best to get used to that idea now, before things start to get heavy.

You would think that objects weighing billions of times the mass of the sun would be easy to find. Alas, it’s rarely that simple.

On behalf of Blue Origin, the opportunity of a lifetime is currently being auctioned off: the last seat on New Shepard, heading to space.

Something happens once you see the world from a different perspective. It's called the "Overview Effect". But what does that mean?

Scientists estimate that our Sun is about 4.57 billion years old. They’re surprisingly confident about that number, too, which opens up an immediate question: how do we know that? The short answer is “a lot of science and math”, but I have a feeling you’re not here for the short answer.
