Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation ...
Researchers report the discovery of a Saturn-sized exoplanet orbiting two M-dwarf stars, which are smaller and cooler than our sun. The findings from this discovery were published in the The Astronomical Journal and were ...

Using the Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new super-Earth exoplanet orbiting a star located about 83 light years away. The newfound alien world is slightly larger than Earth and ...
Astronomers have found an exoplanet that could serve as a benchmark in future studies. It's a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a benchmark for understanding ...

In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in Astronomy and Astrophysics. ...
Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets we've found so far—which in turn makes them interesting for astrobiological surveys. However, there's ...
