There’s a small asteroid that appears to orbit Earth in a horseshoe shape. Sometimes referred to as Earth’s second moon, but it's orbit is much weirder than that.

With new data from the Keck telescopes, Andrea Ghez shows how state-of-the-art adaptive optics are helping astronomers understand our universe's most mysterious objects: black holes. She shares evidence that a supermassive black hole may...

This video is chapter 8 in my series on special relativity, and it presents a hands-on explanation of the resolution to the Twins Paradox using the mechanical minkowski diagram, aka mechanical Lorentz transformation, aka spacetime...

Today Emily Graslie of The Brain Scoop gives us the news about a couple of near- misses for our planet and an update on where astronomers think habitable life might be found in other star systems.

It's leap year time... so what are years, anyway? And what do they have to do with the supermassive black hole in the core of the milky way?

Astronauts ate some space-grown lettuce, and astronomers discovered a ring of galaxies that's so big it defies the laws of physics.

Michael Collins isn't as recognizable a name as Buzz Aldrin and Neil Armstrong, but his job on the Apollo 11 mission was just as important.

How to Find an Exoplanet

Shortly after Jupiter formed, it might have been struck by an object that may have otherwise become its own planet! And researchers have a new estimate of how many Earth-like planets might exist.

No planet’s trip around a star is exactly like the one before it, because solar systems aren't as static as they first appear. Even small nudges can add up to disaster, but some objects find safe orbits with the help of a partner or two.

Will Mars have a ring around it? Hank Green explains in this episode of Scishow Space News!

Skylab set the stage for future space stations like Mir and the ISS, and showed that people really could live in space for a while and do important scientific research.

Our asteroid news edition this week clears up some misleading headlines regarding 3200 Phaethon, and our interstellar visitor has both a new name and a shape we haven’t seen before.

The Juno spacecraft has been making close flybys of Jupiter and its measurements have revealed some new things about Jupiter’s interior. And astronomers were surprised after putting together the most complete atmospheric profile that’s...
