Welcome to the first episode of Crash Course Astronomy. Your host for this intergalactic adventure is the Bad Astronomer himself, Phil Plait. We begin with answering a question: "What is astronomy?"

This edition of SciShow News really is full of "news." Scientists have discovered a new moon orbiting Neptune, a new tick-borne virus threatening the United States, and a new species of shrew who is a real hero. Let's get to it!

Get your gasmasks ready because we're taking a trip to Titan! Reid Reimers tells us all about the mysterious moon.

Today Phil explains how telescopes work and offers up some astronomical shopping advice.<br/>

Explore the four gas giant planets, as Jessi and Squeaks take you on a tour of our solar system!

Astronomers found a galaxy older than almost any we’ve ever seen before, and we have a new, faster method to use in our search for habitable planets.

On January 18, 2002, the National Science Foundation formally opened the Gemini South telescope in Chile. This became the second telescope to make up the Gemini Observatory. Its twin telescope, Gemini North, is located in Hawaii....

On. Oct. 5, 1962, the European Southern Observatory was born!



The European Southern Observatory (ESO) is an intergovernmental research organization made up of 16 nations that work together to study the southern sky. Before...

Something heavy seems to be causing Uranus and Neptune to move in a different orbit than what we can currently account for with the celestial objects we know of. Is there a 9th planet? Does planet 9 exist? Is planet X...

The Chandra X-ray telescope and other observatories are being used to study stars that could potentially harbor habitable planets. Future observatories will use the data to narrow down the list for possible Earth-like planets to image....

The Event Horizon Telescope collaboration managed to capture the 1st image of the Milky Way's black hole in what was a groundbreaking moment for astronomy. Now, they want to snap an even clearer view of the incredible...

Explore the capabilities of cutting-edge telescopes that allow scientists to peer into the depths of space and time.

In this video, the teacher explores the wonders of technology and its impact on our understanding of the universe. From telescopes to observatories, the teacher shares fascinating facts about these tools that help scientists explore...

A pulsing black hole in the centre of a distant galaxy sheds light on black hole and galaxy formation. How fast are black holes rotating and how does that rotation change over its life-span?

This video discusses the advancements in optical interferometry, a technique that combines light from multiple telescopes to create sharper images of stars and galaxies. With the use of the Very Large Telescope in Chile, astronomers are...

This video explores the similarities between Saturn and newly forming star systems, highlighting the relevance of studying Saturn's rings and its moon Titan for understanding planetary formation. It also discusses the detection of over...

How the Very Large Telescope works and how its discoveries about Sagittarius A* lead to a Nobel Physics Prize

Everything you could want to know about Jupiter.

Shot 7 times, yet the Harlan J Smith telescope at the McDonald Observatory still had 99% functionality. How?!

Betelguese, a red super-giant star, could be breaking the laws of physics.

Yes, it is theoretically possible to use telescopes to see if the moon landings were real, but practically no. It would take an incredibly powerful telescope to see signs of moon landings on the lunar surface, and even the best...
