A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star whose planet formation ...

Using gravitational microlensing, scientists have discovered a rare, large planet at the edge of the Milky Way. The planet is ...

Other citizen science groups contributed as well, including the TESS Follow-up Observing Program Sub Group 1 (TFOP SG1) and ...

I n our solar system, Jupiter is the biggest planet at 88,846 miles in equatorial diameter — the distance through the planet from one side to the other at its equator — and a mass of 1,898 × ...

The exoplanet, a planet beyond our solar system, has been dubbed TWA 7b after NASA's James Webb Space Telescope captured ...

Astronomers in Poland have discovered a nearby exoplanet more than 11 times the mass of Jupiter, comfortably putting it in the pantheon of the most massive known worlds. The object is a cold super ...

Orbiting its star in an elliptical path at less than half the distance between Earth and the Sun, this exoplanet offers a ...

The researchers are not the first to propose that the space rock belonged to a group of asteroids that formed beyond the orbit of Jupiter. Their findings, however, strengthen the case thanks to a ...

The planet—named Eps Ind Ab—was observed with the James Webb Space Telescope (JWST), and is at least six times the mass of Jupiter. With a temperature of around 275 degrees Kelvin ...

Perhaps most notably, it has a very low mass — 10% the mass of Jupiter despite being 80% its volume, with an atmosphere of water vapor, methane, carbon dioxide, carbon monoxide and ammonia ...
