Jul 9th: JWST Takes First Direct Image of an Exoplanet
JWST successfully took direct image of a gas giant exoplanet, and that means it has no rocky surface and could not be habitable.
Jun 25th: TRAPPIST-1d: A World on the Edge of Life
Tucked inside a quiet solar system, in the area of sky outlined by the constellation Aquarius, orbits a planet named TRAPPIST-1d, the third of seven planets in a system. More about this planet today with Deep Astronomy
Jun 11th: Direct Imaging Exoplanets In Our Telescopes
There are planets in orbit around stars outside our solar system – and even rogue planets. But finding them is very hard. They are small and dim. But ideally, we’d like to see them directly, in our telescopes. Is that possible?
May 28th: JWST Observes a New Type of Brown Dwarf
Imagine a planet that is so far away from us that it takes 40 years for its light to reach us. Now imagine that this planet has not one, but two stars that it orbits around. And finally, imagine that this planet has clouds made of sand particles that change the brightness of its atmosphere wildly as they move in the air.
May 14th: Life in the Dark: How Moons of Rogue Planets Could Harbor Life
In our galaxy, there are many planets that wander alone in the dark, without a star to orbit. Some of these rogue planets could have moons which remain in tow, and these moons could be more than just cold and barren rocks.
Apr 24th: How Long To Travel to The Closest Exoplanet Proxima Centauri b?
Many people feel that it’s very important for humanity’s long term survival that we become a multiplanet species. But what about traveling to exoplanets? Can we reach the stars?
Apr 9th: A Giant Planet Found Orbiting a Small Star
A massive, Jupiter-sized exoplanet has been discovered orbiting a small, low-mass star and this discovery is challenging theories on how planets form around their stars. This is unusual because planets this large are not supposed to form around low-mass stars.
Mar 26th: The First Exoplanets: A Discovery that Forever Changed Us
Our galaxy likely holds hundreds of billions of planets around other stars but when and how did we begin finding them? What was the first exoplanet detected? It turns out that the first discovery wasn’t one, but two planets in the same system.
Mar 12th: How Do We Find Exoplanets?
What are the best ways to see planets around other stars? One can imagine that it is not easy. This episode looks at ways astronomers find exoplanets.
