A team of astronomers used NASA’s James Webb Space Telescope to study 12 cold brown dwarfs, finding that two — W1935 and W2220 — appear to be near twins of each other in composition.

Astronomers using NASA’s James Webb Space Telescope to study brown dwarfs were surprised to find glowing methane resembling aurora lights on a cold brown dwarf.

The brown dwarf at the center of each disk is detected in the infrared image from Webb. Spectroscopy from the NIRSpec instrument on Webb has confirmed that these objects are brown dwarfs based on ...

Brown dwarfs, also known as "failed stars," could be corrupted by dark matter and transformed into "dark dwarfs" powered by ...

NASA's James Webb Space Telescope has been unwaveringly focused on our universe. With its unprecedented power to detect and ...

Brown dwarfs are bigger than gas giants, but smaller than stars -- and they barely produce any light. The James Webb telescope made it possible to detect them, even if they're 200,000 light years ...

NASA said the object, called CWISE J124909.08+362116.0, could be either a low-mass star or a brown dwarf.

To mark its third year of highly productive science, astronomers used the NASA/ESA/CSA James Webb Space Telescope to scratch ...

The two brown dwarfs form a binary pair called WISE 1049AB that was discovered by NASA's Wide-field Infrared Survey Explorer (WISE) in 2013; the duo sits just 6.5 light-years away from us.
