Astronomers used the powerful James Webb Space Telescope to sleuth out some of these objects, called brown dwarfs, in a ...

Brown dwarfs are celestial objects with masses less than one-tenth of the mass of the sun. This makes them too small to undergo nuclear fusion and shine like stars. Before now, scientists did not ...

A team of astronomers recently tapped into JWST’s capabilities to explore the smallest objects in the Flame Nebula.

NEW ORLEANS — When astronomer Jackie Faherty peered into space using information from the James Webb Space Telescope, there was something she couldn't take her eyes off of. Brown dwarf W1935, a ...

Get Instant Summarized Text (Gist) Two new brown dwarfs, TOI-4776 b and TOI-5422 b, have been discovered using TESS. TOI-4776 b is about 32 times the mass of Jupiter, orbits an F-type star every ...

"The goal of this project was to explore the fundamental low-mass limit of the star and brown dwarf formation process." The James Webb Space Telescope (JWST) has probed deep into the dusty shroud ...

Within the Flame Nebula, there are objects so small that their cores will never be able to fuse hydrogen like full-fledged stars—brown dwarfs. Brown dwarfs, often called "failed stars," over ...

Astronomers also aren't ruling out the possibility that it's a brown dwarf, an object that's between a planet and a star. The latest research builds on existing observations by NASA's Hubble and ...

Due to their close proximity, the white dwarf strips mass from its low-mass companion. This process has removed about 90 per cent of the mass of the companion, turning it from a star into a brown ...

In this feature, learn the difference between pulsars and quasars, antimatter and dark matter, brown dwarfs and white dwarfs, and many other extraterrestrial wonders. Accretion—The collection of ...

July 13, 2023 — Brown dwarf stars rarely emit radio waves. Here scientists have found the coldest star yet emitting at these long wave lengths. Understanding the science of 'ultracool brown ...
