Astronomers at Western University have discovered the most rapidly rotating brown dwarfs known. They found three brown dwarfs that each complete a full rotation roughly…
Planetary scientists wondered if bands of winds or swirling storms dominated the atmospheres of brown dwarfs. University of Arizona-led research has solved the mystery. A…
Gemini North and IRTF Confirm LOFAR Discovery For the first time, astronomers have used observations from the LOFAR radio telescope, the NASA IRTF, operated by…
Citizen scientists and NOIRLab facilities key to discovery of almost 100 nearby cool brown dwarfs. How complete is our census of the Sun’s closest neighbors?…
Data from NASA’s NEOWISE mission, managed by the agency’s Jet Propulsion Laboratory, fuels the search for these not-quite-planets-but-not-quite-stars. With the help of citizen scientists, astronomers…
Astronomers have used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and NASA’s Spitzer Space Telescope to make the first measurement of…
Not quite planets and not quite stars, brown dwarfs are cosmic in-betweeners. Learning about their atmospheres could help us understand giant planets around other stars….
A team of astronomers led by Brendan Bowler of The University of Texas at Austin has probed the formation process of giant exoplanets and brown…
Brown dwarfs, the larger cousins of giant planets, undergo atmospheric changes from cloudy to cloudless as they age and cool. A team of astronomers led…
Pluto hogs the spotlight in the continuing scientific debate over what is and what is not a planet, but a less conspicuous argument rages on…
In an unprecedented deep survey for small, faint objects in the Orion Nebula, astronomers using NASA’s Hubble Space Telescope have uncovered the largest known population…
Twinkle, twinkle, little star, how I wonder what you are. Astronomers are hopeful that the powerful infrared capability of NASA’s James Webb Space Telescope will…
Taking a picture of an exoplanet—a planet in a solar system beyond our sun—is no easy task. The light of a planet’s parent star far…
Using data from NASA’s Spitzer Space Telescope, astronomers reveal that the varying glow of brown dwarfs over time can be explained by bands of patchy…
The Backyard Worlds: Planet 9 Citizen Science Project has discovered its first substellar object, WISEA J110125.95+540052.8 – a T5.5 brown dwarf located approximately 34 pc…
A newly published Harvard-Smithsonian study of the twenty-four known Y-dwarfs finds that the models for the coolest of them fail to explain the observed properties….
Astronomers have identified a brown dwarf that was formed about 10 billion years ago and is made of gas that is around 250 times purer…
Using the Very Large Array, an international team of astronomers has discovered jets of material ejected by still-forming young brown dwarfs, revealing the first direct…
