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...

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.

Now that gravitational waves are definitely a thing, it's time to think about some of the crazy things we can figure out with them. In some cases we're going to need a gravitational wave observatory - in fact, we've already built one.

SciShow Space starts the year off with a bang, and the discovery of 8 Earth-like planets, two of which may be the most promising candidates yet for harboring life.

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.

There's something out there SO massive that it's pulling on every object within hundreds of millions of light years. But we can't see it! So what DO we know? Today on SciShow Space, Reid Reimers tells us more about the Great Attractor.

Hank reports on the discovery by NASA scientists of the most distant, oldest galaxy ever observed.

It has NO EDGE. And NO CENTER... or does it?

Painter Alyssa Monks finds beauty and inspiration in the unknown, the unpredictable and even the awful. In a poetic, intimate talk, she describes the interaction of life, paint and canvas through her development as an artist, and as a...

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...

Gamma-ray bursts are not only incredible to study, but their discovery has an epic story all its own. Today Phil takes you through some Cold War history and then dives into what we know. Bursts come in two rough varieties: Long and...

The exploding “cow” around 200 million light-years away is running astronomers for a loop, but if it is what some hypothesize, we are witnessing a first for astronomy! Meanwhile, we got photographic evidence of a planet orbiting a binary...

Henrietta Swan Leavitt was one of a number of volunteer women astronomers who were allowed to serve as "computers" at Harvard College Observatory, doing tedious work male scientists wouldn't do, and ultimately making a discovery now...

Are aliens watching Earth TV?

All of humanity likely saw it, a brilliant supernova that lit up the daytime sky in 1054. But 960 years later, there’s still a lot we dont quite understand about the famous celestial phenomenon.

A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the...

When we look at the sky, we have a flat, two-dimensional view. So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine...

Active galaxies pour out lots of energy, due to their central supermassive black holes gobbling down matter. Galaxies tend not to be loners, but instead exist in smaller groups and larger clusters. Our Milky Way is part of the Local...

The Milky Way is our neighborhood in the universe. It’s a galaxy and there are many others out there. Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular....

Down here, on Earth, if you look up at the night sky, it seems like all the stars up there look the same. Or maybe at least similar. But, it turns out that stars are very different and we shouldn't stereotype them. Some are bigger, some...

Is it possible that what we have invented as dark matter to explain the motion of stars in galaxies and clusters is a figment of our imagination? Could it be that Einstein’s General Relativity has a flaw? Does...

Then Isaac Newton in 1687 showed that planets move due to the same forces we experience here on earth. If things could be explained with mathematics, to many people this called into question the need for a...

James Webb captures infrared light, which allows us to see billions of light years away. Some galaxies would not be visible otherwise, because their light has redshifted beyond visible light spectrum due to the...

The Milky way galaxy is composed of up to 400 billion stars, and at least that many planets. Our star, the sun is one of those billions, about a third to halfway out from the galactic center....
