A recent study published in The Astronomical Journal discusses the discovery of a Neptune-like exoplanet whose radius is slightly larger than three times the Earth while orbiting within the habitable ...

An artist’s interpretation of TOI 4633 c, a Neptune-like exoplanet found orbiting the habitable zone of a sunlike star. The system contains a second star (right) and may also host another exoplanet ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

As the name implies, NASA's Transiting Exoplanet Survey Satellite (TESS) was designed to spot exoplanets, but it's flexible. A team of professional and amateur astronomers have used the planet hunter ...

This artist’s concept illustrates how tightly the three stars in the system called TIC 290061484 orbit each other. If they were placed at the center of our solar system, all the stars’ orbits would be ...
