Scientists from UNSW Sydney have located a potential new exoplanet—a planet that orbits a star outside of our solar system—using a technique known as "transit timing variation." In research ...

When 2024’s record-breaking global average temperature exceeded the Paris Agreement-set 1.5-degrees Celsius warming threshold, the oft repeated warning was that a single year above that mark does not ...

The hunt for planets beyond our solar system has turned up more than 4,000 far-flung worlds, orbiting stars thousands of light years from Earth. These extrasolar planets are a veritable menagerie, ...

"This new planet supports the theory that high eccentricity migration should account for some fraction of hot Jupiters," says Sarah Millholland, assistant professor of physics in MIT's Kavli Institute ...
