Astronomers have finally weighed a wandering “rogue” planet, uncovering a Saturn-mass world flung into the galaxy after a ...

Using JWST, scientists discovered PSR J2322-2650b — a carbon-rich, lemon-shaped exoplanet orbiting a pulsar — challenging ...

Researchers have confirmed the mass of a free-floating planet thanks to a lucky convergence of ground- and space-based ...

The exoplanet, dubbed PSR J2322-2650 b, has a helium-and-carbon atmosphere, something researchers say they've never seen ...

When astronomers first cataloged some of the closest orbiting rocky exoplanets, they wrote them off as bare, airless cinders, ...

But that’s nothing compared with PSR J2322-2650b, an object the mass of Jupiter studied recently by the James Webb Space Telescope. This planet’s equatorial diameter is about 38 percent wider than its ...

Astronomers have uncovered a massive hidden planet and a rare “failed star” by combining ultra-precise space data with some of the sharpest ground-based images ever taken. Using the Subaru Telescope ...

Astronomers photographed a baby planet, WISPIT 2b, during its formation process within a dusty ring around its star system.

Pluribus imagines Kepler-22b as an ocean world that sends a gift to humanity through radio waves. In real life, no such ...

It's an evocative idea that has long bedeviled scientists: a huge and mysterious planet is lurking in the darkness at the edge of our solar system, evading all our efforts to spot it. Some astronomers ...

When Earth was a molten inferno, water may have been locked safely underground rather than lost to space. Researchers ...
