Using data from ESA's Gaia satellite and the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), astronomers have investigated three open clusters near the Aquila Rift cloud. They found that two of them, designated ...
Using data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and ESA's Gaia satellite, astronomers have detected 21 new high-probability extremely low-mass white dwarfs. The finding is reported in ...
Since its launch in 2013 ESA's Gaia observatory has been mapping our galaxy from Lagrange point 2, creating the most accurate and complete multi-dimensional map of the Milky Way. By now two full sets of data have been released, ...

Astronomers report the discovery of another exoplanet around a nearby star known as HD 83443. The newfound extrasolar world is a Jupiter-mass planet orbiting its host on a highly eccentric 22-year orbit. The finding was detailed ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers from the Pennsylvania State University (PSU) and elsewhere have detected a new Jupiter-sized extrasolar world. The newfound exoplanet, designated TOI-3757 ...
