When we say a planet is habitable, we aren't REALLY saying what we think we are saying. 'Habitable' means something else. Is Kepler 186f habitable, in the true sense of the word? And if not, what other planets should we be looking at?...

We've found thousands of exoplanets over the years, but if we're going to find one that can sustain life, we need to take a look at the one planet we know that can, Earth.

SciShow Space explores the latest mission to search for extraterrestrial life, and the mission of two tiny satellites that aims to make space travel safer.

You like space exploration, and we like space exploration. So why aren't we investigating our closest to galactic neighbor, the triple star system Alpha Centauri? Is it time to give interstellar travel a shot? How would we do it? Hank...

Today Phil explains that YES, there are other planets out there and astonomers have a lot of methods for detecting them. Nearly 2000 have been found so far. The most successful method is using transits, where a planet physically passes...

For the first time, astronomers have detected the light coming from an exoplanet. SciShow Space News explains how they did it, and why it was so difficult in the first place.

Research suggests that nearly every star has at least one planet, but we haven't found any other solar systems that look quite like ours.

Dark Matter may be detected via Exoplanets. All the matter that is visible to us constitutes only about 18% of the total matter that we think actually exists in the universe. We know this because when all the known mass of a galaxy like...

Why Earth 2.0 may not be such a feasible place for people to live.

40 Jupiter Mass Binary Objects - or JuMBOs - discovered by JWST.

Ronak came up with a new design for the phoropter, the device used to determine eye-glass prescriptions. It's basically been unchanged for 200 years. Using a liquid lens, he miniaturized the device and wrote an algorithm to determine...

It seems counterintuitive, but ESA's newest space telescope, CHEOPS, is designed to take blurry images of stars. But this helps astronomers to understand more about orbiting exoplanets than a clear image would. Here's why!

Astrum investigates some examples of the longest and shortest years that we know of. The differences are mind-boggling!

There is an exoplanet, discovered by ESO's VLT, where it rains iron. But WASP-67b is 690 light years away, how could we possibly know that?

Scientists suppose there could be other life-bearing planets like Earth. To find them, they are looking for 'wobbling' stars. Physics - Universe - Learning Points. When a planet orbits a star, it has just enough gravitational force to...

Discover the billions of Sun-like stars outside our solar system. Physical processes -The Earth and beyond - Beyond our solar system Learning Points Exoplanets orbit stars outside our solar system. A Twig Tidbit Film - Clip. A short film...

This video explores the exciting field of exoplanet discovery, focusing on the techniques used to detect planets outside our solar system. It highlights the challenges astronomers face in finding these planets and introduces the concept...
