NASA’s Webb Peers Deeper into Mysterious Flame Nebula

The Flame Nebula, located about 1,400 light-years away from Earth, is a hotbed of star formation less than 1 million years old. 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 time become very […]

NASA’s Webb Exposes Complex Atmosphere of Starless Super-Jupiter

An international team of researchers has discovered that previously observed variations in brightness of a free-floating planetary-mass object known as SIMP 0136 must be the result of a complex combination of atmospheric factors, and cannot be explained by clouds alone.

A Solar Neighborhood Census, Thanks to NASA Citizen Science

To take a census of nearby cosmic objects, sending out a survey won’t work. Scientists need to use many telescopes with different specializations to chart what is in the general neighborhood of the Sun. Looking to understand more about our neighbors and how they came to be, scientists collaborate with citizen scientists, volunteers from around […]

NASA’s Hubble Finds that Aging Brown Dwarfs Grow Lonely

It takes two to tango, but in the case of brown dwarfs that were once paired as binary systems, that relationship doesn’t last for very long, according to a recent survey from NASA’s Hubble Space Telescope. Brown dwarfs are interstellar objects larger than Jupiter but smaller than the lowest-mass stars. They are born like stars […]

NASA’s Webb Finds Signs of Possible Aurorae on Isolated Brown Dwarf

Infrared emission from methane suggests atmospheric heating by auroral processes. Astronomers using NASA’s James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere.

NASA’s Webb Identifies Tiniest Free-Floating Brown Dwarf

Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable […]
