Astronomers have finally found evidence to help solve the missing baryon problem, and they're pointing telescopes toward the Intergalactic Medium to figure it out.

SciShow Talk Show is back! Hank talks to Jimmy Henderson about project MINERVA, or is it the MINERVA Project? Special Guest Jessi Knudsen Castañeda introduces two red eyed crocodile skinks!

Hank tells us about the Kepler Space Telescope and its new data!

On March 17, 2014, a group of physicists announced a thrilling discovery: the “smoking gun” data for the idea of an inflationary universe, a clue to the Big Bang. For non-physicists, what does it mean? TED asked Allan Adams to briefly...

At least some advanced civilizations might be producing tons of waste heat by now. And researchers are looking for them.

Eta Carinae A, a star that briefly held the title of the second-brightest star in the sky, has been dazzling astronomers for centuries. Learn more about this type of supermassive, mega-luminous star, known as a Luminous Blue Variable.

In 2009, a team of Japanese astronomers discovered Himiko Blob which is a very bright galaxy, its light originally wouldn’t be able to make it through the atmosphere. So why were those astronomers able to discover it?

Scientists have discovered a shard of a planet that survived the death of its star and TESS has found the first direct evidence of an exocomet.

We've only found one planet in a globular cluster, where gravitational interactions should usually rip baby planets apart, but that's not all that excites astronomers about PSR 1620-26 b.

This week in space news, a new makeover for one of the Hubble Telescope's most famous images, and tips on spotting Comet Lovejoy in the night sky.

Aliens - Are We Looking in the Wrong Place?

Thanks to X-ray telescopes, scientists in the 1970s found the first real evidence that black holes actually existed, and astronomer Andrew Fabian has used X-ray research to unlock incredible mysteries ever since, including a giant sound...

The fact that no one knows the answer to this question is what makes it exciting. The story of physics has been one of an ever-expanding understanding of the sheer scale of reality, to the point where physicists are now postulating that...

Hank talks about a shiny element that has fascinated humans for millenia.

Researchers think they may have found a new way to study planets after they've been "buried" in a star! Astronomers are also officially acknowledging the discovery of a distant body with a thousand-year orbit and an adorable nickname.

Today on Crash Course Astronomy, Phil dives into some very dark matters. The stuff we can actually observe in the universe isn’t all there is. Galaxies and other large structures in the universe are created and shifted by a force we...

Educator Roy Gould and researcher Curtis Wong show a sneak preview of Microsoft's WorldWide Telescope, which compiles images from telescopes and satellites to build a comprehensive, interactive view of our universe.

It's been said that when an elder dies, it's as if a library is burned. Anthropologist Elizabeth Lindsey, a National Geographic Fellow, collects the deep cultural knowledge passed down as stories and lore.

The sun may have thousands of stellar siblings, many of them probably just like it, elsewhere in the galaxy. Find out how astronomers are looking for them, and learn about a match that could be our star's long-lost sibling!

You’d think it would be easy to tell if an object in space was a star or a planet - is it big, hot, and shining? It’s a star! Small, cool, and made of rock and gas? Planet! But cosmic oddities know as brown dwarfs remind us that the...

We’ve discovered a planet that, for its size, is in a very strange place around it’s star! And other scientists, inspired by comets, have come up with a new way to potentially make breathable oxygen for people exploring Mars in the future.

In October 2017, astrobiologist Karen J. Meech got the call every astronomer waits for: NASA had spotted the very first visitor from another star system. The interstellar comet -- a half-mile-long object eventually named `Oumuamua, from...

Tidally locked planets could be more common than Earth-like planets! And these 'eyeball planets' might even be a promising place to look for unique lifeforms!

The ESA Hipparcos team worked for 20 years on the project, then had to watch as the mission ALMOST failed! But somehow, they turned it around, and today, this little-known mission has totally transformed what we know about space.
