An international team of astronomers has discovered a new inflated "hot Jupiter" exoplanet as part of the Next Generation Transit Survey (NGTS). The newfound alien world, designated NGTS-21b is about 30% larger and more than ...
Astronomers report the detection of a new brown dwarf as part of the Ophiuchus Disk Survey Employing ALMA (ODISEA) program. The newfound object, designated SSTc2d J163134.1-24006, appears to be experiencing a quasi-spherical ...
Jupiter-sized planets can be stolen or captured by massive stars in the densely populated stellar nurseries where most stars are born, a new study has found.
