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 ...
As comets approach the Sun, they release gas and dust known to astronomers as cometary activity. For comets passing near or inside Earth's orbit, this activity slows over successive orbits. University of Oklahoma astronomer ...

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 ...
An international team of astronomers has performed timing observations of an eccentric millisecond pulsar known as PSR J0955−6150. Results of the observational campaign, published March 1 on the arXiv pre-print server, ...
Astronomers have identified two different cases of "mini-Neptune" planets that are losing their puffy atmospheres and likely transforming into super-Earths. Radiation from the planets' stars is stripping away their atmospheres, ...
