Astronomers study a lot of gorgeous things, but nebulae might be the most breathtakingly beautiful of them all. Nebulae are clouds of gas and dust in space. They can glow on their own or reflect light from nearby stars. When they glow...

Models of the universe’s early days have only been possible with dark matter as a variable, but we still don’t have proof that dark matter exists. But recently, scientists may have found a way to replicate the results without the...

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...

In 1986, a prospecting crew in southern Romania was looking for a good place to build a geothermal power plant, when they accidentally discovered one of the oddest caves of all

In 1995, scientists pointed the Hubble Telescope at an area of the sky near the Big Dipper. The location was apparently empty, and the whole endeavor was risky _ what, if anything, was going to show up? But what came back was nothing...

Legendary scientist David Deutsch puts theoretical physics on the back burner to discuss a more urgent matter: the survival of our species. The first step toward solving global warming, he says, is to admit that we have a problem.

Sharks come in a lot of different shapes and sizes and many of them don't look like the ones you see in movies. Here are seven sharks that went down some decidedly strange evolutionary paths.

Penguins are infamous for being ready for any formal event, yet it seems that we're still unsure why they, and numerous animals have this distinct color contrast.

Jessi and Squeaks love science mysteries, and today they've teamed up with their friend, Dino, to try and solve one of the biggest mysteries of all: what happened to the dinosaurs?

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...

Emily Graslie of The Brain Scoop is back again to stump Hank and to tell us about some fascinating new research in the field of rat telepathy (NO JOKE). Then Jessi from Animal Wonders shares Zoe the Red-lored Amazon parrot.

In this video Paul Andersen defines natural selection as differential reproductive success. He then explains how natural selection shapes organisms on our planet through variation and selection. A K-12 teaching progression is also...

Vaccine-autism claims, "Frankenfood" bans, the herbal cure craze: All point to the public's growing fear (and, often, outright denial) of science and reason, says Michael Specter. He warns the trend spells disaster for human progress.

Normally when you blink, you don’t really notice, and it turns out your brain is playing a bit of a trick on you to make that happen!

Null results often get a bad rap, sometimes characterized as a study "finding nothing," but there's a lot we can learn from studies whose results fail to support their hypotheses.
