While analyzing the data from the Next Generation Transit Survey (NGTS), an international team of astronomers has discovered a new brown dwarf. The newfound object, designated NGTS-28Ab, orbits its host star in just about ...
Using the James Webb Space Telescope (JWST), astronomers have observed a nearby cold brown dwarf designated WISEPA J182831.08+265037.8 (or WISE 1828 for short). The observations delivered important insights into the composition ...
Using the Keck II telescope, astronomers have performed near-infrared spectroscopic observations of a nearby brown dwarf known as CWISE J105512.11+544328.3, or W1055+5443 for short. Results of the observational campaign, ...
Astronomers report the discovery of a new massive brown dwarf using the Zwicky Transient Facility (ZTF). The newly detected object is about 80 times more massive than Jupiter and orbits a low-mass star. The finding was detailed ...
Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images of persistent, intense ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new massive brown dwarf. The newfound object is nearly 80 times more massive than Jupiter and orbits an M-dwarf star known as TOI-5375. ...
Using the Near Infrared Camera (NIRCam) onboard the James Webb Space Telescope (JWST), an international team of astronomers has discovered the first known binary system composed of two Y-type brown dwarfs. The finding was ...
Using NASA's James Webb Space Telescope (JWST), astronomers have observed a nearby brown dwarf known as HD 19467 B. Results of the observational campaign, published January 26 on the arXiv pre-print server, yield important ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new warm brown dwarf. The newfound object, designated HIP 33609 b, transits a bright and rapidly rotating star. ...
