At just four light years away, Proxima Centauri is our closest solar neighbor. The recent discovery of the new exoplanet Proxima D, has reopened the discussion of whether the proxima system is our best chance at reaching another Earth....

Hunting for rogue planets is like hunting for an invisible needle in a haystack. But we're getting a much clearer view thanks to gravitational microlensing surveys. And it looks like there are a LOT more of them out there than we thought.

We’ve sent thousands of things into space over the years! Many of them just orbit the Earth, and some are flying out past the edges of the Solar System. In this episode, we present our favorite currently active space probes!

Life on Earth depends on the steady nature of our star, and an international team of scientists searched thousands of other stars to try to find out if the sun has always been as consistent as it is now. And According to a study...

Scientists have worked out how likely it is that distant planets can see earth, and we are learning new ways to study the magnetic fields of galaxies.

Everyone has their own opinion as to whether or not aliens exist. But let's assume they do for a second and we wanted to let them know we're here!!!! How should we signal our species' existence through the expanse of space? There are a...

SciShow explains the science of detecting exoplanets -- planets in orbit around distant stars -- and how a new observatory being built in California may open up whole new worlds to us, literally!

We’ve sent thousands of things into space over the years! Many of them just orbit the Earth, and some are flying out past the edges of the Solar System. In this episode, we present our favorite currently active space probes!

Exorings are pretty elusive, but we’ve already found what might be the first set of exorings, and if we find more, we’ll have a treasure trove of new information.

Theoretically, we could hide the Earth from faraway telescopes, using a properly placed laser pointer.

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!

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...

Gravitational microlensing events are revealing the mysteries of rogue planets, but what are they, and how does it work? And what role does the Nancy Grace Roman Space Telescope play in helping us spot more rogue planets in the future?

Extrasolar planets, or exoplanets, are planets that orbit stars other than our sun. Astronomers like Dr. William Welsh at San Diego State University primarily use two methods to detect these distant planets: Doppler and Transit...

A “super-Earth” orbiting a red dwarf star has been discovered only 36 light years from Earth, according to a study published in the Astronomy & Astrophysics journal.

A conversation with one of TIME Magazine’s 100 Most Influential People, Natalie Batalha, the Kepler mission project scientist at NASA’s Ames Research Center in Silicon Valley.

Gravitational microlensing events are revealing the mysteries of rogue planets, but what are they, and how does it work? And what role does the Nancy Grace Roman Space Telescope play in helping us spot more rogue planets in the future?

A conversation with Steve Howell, NASA Senior Research Scientist on astrophysics.

What do we know about the planets outside our solar system? NASA planet hunters Jessie Christiansen and Knicole Colon take us beyond...into the exciting world of exoplanets.

A conversation with Charlie Sobeck, Kepler mission manager at NASA’s Ames Research Center in Silicon Valley.

Astronomers using NASA’s Hubble and Kepler space telescopes have uncovered tantalizing evidence for what could be a moon orbiting a gas-giant planet that orbits the star Kepler 1625, located 8,000 light-years away in the...

The Hubble and Kepler space telescopes found evidence for what could be a giant moon accompanying a gas-giant planet that orbits the star Kepler-1625, located 8,000 light-years away in the constellation Cygnus. The moon may...
