A bizarre lonely star grows brighter, and we investigate a study that looks at whether astronauts that leave the magnetosphere have higher incidences of heart disease.

The effects of dark matter on galaxies is a mystifying and difficult thing to study, but the Milky Way's galactic bar might present an exciting way to quantify how much of it exists!

When something breaks on a spaceship, there's not an auto-shop it can pull up to, so NASA scientists have to get creative.

At TED2012, filmmaker Karen Bass shares some of the astonishing nature footage she's shot for the BBC and National Geographic -- including brand-new, previously unseen footage of the tube-lipped nectar bat, who feeds in a rather unusual...

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.

What’s irrational and never ends? Pi! Hank explains how we need pi to explain some of the most basic but most important principles of the universe, in honor of Pi Day.

every minute, 400 pounds of hydrogen and almost 7 pounds of helium escape from earth's atmosphere into outer space. Astrophysicist Anjali Tripathi studies the phenomenon of atmospheric escape, and in this fascinating and accessible talk,...

SciShow Space celebrates the Falcon 9 vertical landing and looks forward to new missions in space! Also-- are globular clusters a good place to look for extraterrestrial life? Find out in this episode of SciShow Space News!

Scientists have discovered over 5,000 exoplanets in the last few decades, but where are the Exo-Earths?

Some scientists are hoping to use our motion through the galaxy to help detect some of the most elusive particles of all: dark matter.

Astronomers have used a few different methods to detect exoplanets, and improved telescopes are increasing the rate of discovery. But is it possible that any stars DON'T have planets, or are they just an expected feature of stellar...

Lasers are incredible narrow beams of light we can use to do everything from cutting metal to operating on people's eyeballs. But even though we came up with the idea on our own, humans didn’t actually make the first lasers.

Find out what kinds of things are lurking near the center of our galaxy!

Most galaxies that we know of are spirals, including the Milky Way, but how do they form and keep their shape over billions of years?

Firefly takes place in an incredibly complicated star system. But it probably couldn't exist, because physics.

Earth is unique in that it's the only planet we know of that can support life. But could there be another planet like ours somewhere far away?

Have you ever wondered what the sun is made of? Dr. Cecilia Payne-Gaposhkin wondered that, too, and she used science to figure out the answer! Find out how she did that and more about her amazing life and...

In the court of the Jade Emperor, a young princess had a special skill: she could pluck clouds from the sky and spin them into the softest robes. But her craft was the same day after day, and she longed for new inspiration. So the Queen...

Learn about what might be one of the most important exoplanets we've discovered yet, and what you need to apply to become an astronaut!

How Many Stars There Are in the Sky, Explained in Ten Seconds

Could human civilization eventually spread across the whole Milky Way galaxy? Could we move beyond our small, blue planet to establish colonies in the multitude of star systems out there? These questions are pretty daunting, but their...

Astronomers have gotten pretty good at calculating how fast the universe is expanding, but new measurements don’t line up with the predictions of well-tested laws of physics. Now scientists have a new question to ponder: Why are these...

Phil Plait was on a Hubble Space Telescope team of astronomers who thought they may have captured the first direct photo of an exoplanet ever taken. But did the evidence actually support that? Follow along as Plait shows how science...

Most of the universe is made up of dark matter, so could it form into stars and galaxies like regular matter?
