V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that connection measurable. Future transit-timing and atmospheric observations ...

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

Most of the exoplanets we’ve discovered have been in relatively tight orbits around their host stars, allowing us to track them as they repeatedly loop around them. But we’ve also discovered a handful ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets seem to have been knocked out of their orbits, floating through space free ...

Astronomers have detected a rogue planet with a mass equivalent to that of Saturn, and by taking observations from both the ground and space, they have also been able to measure its size and distance ...

Nearly 10,000 light years away, a planet the size of Saturn is floating all on its own through empty space. In a stroke of luck, researchers were able to spot this strange, dark world using both ...

It was almost 100 years ago that Clyde W. Tombaugh discovered Pluto. That was the last planet found until 1992, when humans found another one. But this new planet wasn't in our solar system—it was ...

The Hubble Space Telescope has peered at Uranus, left, and Neptune to study the so-called "ice giant" planets, but little is known about their interior composition. Credit: NASA / ESA / M. Showalter / ...

Planet Labs beat on earnings last night. The spy satellite operator is hitting its stride, and generating consistent free cash flow. Heading into the fiscal Q3 2026 report, analysts weren't optimistic ...

Morgan Underwood receives funding from NASA-funded CLEVER Planets (Cycles of Life-Essential Volatile Elements in Rocky Planets) research project. When astronomers search for planets that could host ...

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature ...

Some planets might produce their own water instead of relying on outside sources. In laboratory experiments, researchers simulated extreme conditions found within certain exoplanets by blasting ...
