Two new celestial objects have been confirmed using Gaia data, including a Super-Jupiter exoplanet and a brown dwarf. The discovery challenges current theories of planet formation and provides valuable data for understanding these intriguing objects. Gaia's ongoing mission will uncover hundreds of planets and brown dwarfs around nearby...
A UTSA-led research team has discovered a new exoplanet using indirect methods. The exoplanet, HIP 99770 b, is about 14 to 16 times the mass of Jupiter and orbits a nearly twice-as-massive star. This breakthrough opens a new avenue for scientists to discover and characterize exoplanets.
Researchers at UC Berkeley have detected a possible free-floating black hole in the Milky Way galaxy using gravitational microlensing. The object's mass is estimated to be between 1.6 and 4.4 times that of the sun, but its nature as a black hole or neutron star remains uncertain.
Researchers have directly imaged four new brown dwarfs orbiting stars from far away, significantly advancing our understanding of these enigmatic objects. The study utilized a novel approach combining space and ground-based facilities to detect hidden companions.
