An international team of astronomers reports the detection of a new, hot-dust-obscured galaxy (DOG). The galaxy, which received designation WISE J190445.04+485308.9, was found at a relatively low redshift of 0.415, which ...
Astrophysicists from the Hebrew University of Jerusalem published a new theoretical model that solves the mystery of the formation of early massive galaxies in the universe, in Monthly Notices of the Royal Astronomical Society. ...

Indian astronomers have carried out deep optical photometric observations of the Galactic open cluster Bochum 2 using the 1.3m Devasthal Fast Optical Telescope (DFOT). Results of the observational campaign, published May ...
Using the James Webb Space Telescope (JWST) and the Hubble Space Telescope (HST), astronomers from the University of Padua, Italy, and elsewhere have observed a metal-poor globular cluster known as Messier 92. The observations ...
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. ...
Researchers using the James Webb Space Telescope (JWST) have taken a first look at their data that probe the chemistry of the regions of disks around young stars where rocky planets form. Already at that stage, the data reveal ...
