Exoplanet Radio - Ep. 18: JWST Observes a New Type of Brown Dwarf

The 365 Days of Astronomy

From Aug 11, 2023.

Hosted by Tony Darnell.

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.

This planet, VHS 1256 b, has recently been observed by the James Webb Space Telescope and it is a very interesting world. It is not like any of the planets in our solar system, or even like most of the planets that we have found outside our solar system. It is a type of planet called a brown dwarf, which is somewhere between a giant gas planet and a small star. Brown dwarfs are very hard to study, because they are very faint and cold compared to stars, and very bright and hot compared to planets.
