Exoplanets are planets orbiting stars outside the solar system, and every month seems to bring in a new batch of weird, wild, and wonderful worlds.

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

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.

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?

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...

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

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.

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

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.

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.

NASA’s Perseverance team is working in tandem with the Navajo Nation to use their native language in defining rocks and soil found on Mars. 50 words have been approved to name these landmarks.

Things are getting a little crowded at the red planet.
