Something massive, with roughly 1,000 times the area of earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing...

We have new insights into the bizarre nature of lava planets, and the icy moon Europa may yet reveal some of her salty secrets.

We’ve done a lot of searching for life in the universe and we need to continue to if we hope to make contact. But not all of our attempts were expected to succeed. That’s where Beacon in the Galaxy comes in.

Jessi has a special guest today who is an expert on the night sky! Join Jessi and Sam the Bat to learn all about constellations, and to test your star knowledge by making flash cards!

Humans have been studying the stars for thousands of years, but astrophysicist Juna Kollmeier is on a special mission: creating the most detailed 3-D maps of the universe ever made. Journey across the cosmos as she shares her team's work...

Science isn't always a visual medium, but I think it's most important moments have often been captured in photos and illustrations. I picked out some of my favorite science images from history.

What was once thought to be a black hole might in fact be a star that feeds on its own kind!

There’s a massive black hole next door that appears far too big for its host galaxy! And in another galaxy, TWO supermassive black holes formed, giving us a glimpse at a true rarity in astronomy!

X-rays leaking from dead stars could breathe new life into a hypothetical particle theory, plus an ancient Titanic force may have helped twist Saturn’s axis.

Thanks to NASA's James Webb Space Telescope (JWST) project and the Space Telescope Science Institute for supporting this video.



This video is about the line between Brown dwarfs and gas giant planets (aka...

SciShow Space News explains two of the Hubble Space Telescope's most important discoveries, and why the MESSENGER probe is about to crash into Mercury.

But maybe don't bust out the moisture farm equipment just yet!

Welcome back to Scishow Quizshow! In this episode Hank Green and Caitlin Hofmeister go head to head to compete for subbable subscribers.

What kinds of tools do astronomers use to calculate the age of the universe, and how can they determine the speed of its expansion?

Our neighboring star Betelgeuse got noticeably dimmer a few months ago, and thanks to the Hubble telescope, we recently figured out what was going on. Also, the Arecibo Observatory in Puerto Rico suffered some damage this week.

You'd think that two planets with similar stats, orbits, and parent stars would grow up to be pretty similar, but these twins have atmospheres that beg to differ.

The great advances in any science tend to come in sudden leaps. April 25th of 2018 marks the beginning of just such a leap for much of astronomy. In the early hours of the morning, the Gaia mission's second data release dropped. Our...

Massive stars fuse heavier elements in their cores than lower mass stars. This leads to the creation of heavier elements up to iron. Iron robs critical energy from the core, causing it to collapse. The shock wave, together with a huge...

Hank continues our series on the four fundamental forces of physics with a description of gravitation -the interaction by which physical bodies attract with a force proportional to that of their masses, and which is responsible for...

In the late 16th century, Tycho Brahe built an observatory on an island and collecting some of the most accurate data ever. He also lost his nose in a duel with a classmate -- over who was the better mathematician.

Hank tells us about NASAs discovery of the 1st planet ever discovered to be orbiting a binary star.

Last year LIGO announced the detection of gravitational waves from the merger of two black holes. The science world went a little crazy. Only a few weeks ago a new rumour emerged: that LIGO had, for the first time, spotted gravitational...

Scientists studying quantum vortices and their impact on superconductivity just won the Nobel Prize.
