Salty clouds discovered on pink puffball planet

A cold, cherry-blossom-hued exoplanet supports bizarre clouds chock-full of salts

".. GJ504b might not actually be a planet at all; it’s about 25 times the mass of Jupiter,.. .. used the James Webb Space Telescope (JWST) to capture the dim light emanating from the object. .."

What a Signal in a Failed Star’s Clouds Means for the Search for Life
The detection of the molecule #phosphine in a #browndwarf’s atmosphere may help #astronomers in their search for life elsewhere in the Milky Way,a molecule that on this planet is produced by living things.
This discovery is not life, the astronomers say. Any life as we know it would be impossible to sustain in such an environment.

Scientists Find a Quadruple Star System in Our Cosmic Backyard
First, the #astronomers identified what they believed was a lone #browndwarf orbiting a bright single #star. Further investigation revealed that the brown dwarf was actually two. After submitting a paper about the discovery, Dr. Zhang said, they realized that the bright companion was a pair of #stars, too.
“I like to call this a double-double,” said Adam Burgasser, an #astrophysicist.
