Astronomers have photographed for the first time a growing planet embedded in a dark gap of a dusty, multi-ringed disk around a young star -- offering rare evidence of how giant planets form. “Dozens ...

A new peer-reviewed study finds that early planet formations were assembled from fragments of earlier bodies within the Solar System.

Our solar system is a smashing success. A new study suggests that from its earliest period—even before the last of its nebular gas had been consumed—Earth's solar system and its planets looked more ...

The timing of Earth's early formation points to a planet that started out dry. So, life’s essential building blocks arrived ...

Since the first discovery of planets beyond the solar system in 1995, more than 6,000 exoplanets have been identified. Many of these planets have properties that differ significantly from the eight ...

Mercury, the smallest planet in our solar system, has captivated scientists due to its extreme temperatures, dense iron-rich core, magnetic field, and distinctive geological features. Recent research ...

The main working hypothesis for the Mercury problem says that the planet is the victim of a collision with a different-sized object. The cataclysmic collision stripped much of the planet's mantle and ...

A new image has revealed the clearest glimpse yet of an interstellar visitor zipping through our solar system. The Hubble Telescope and its Wide Field Camera 3 got an incredible view of the comet ...

Recent research indicates Mercury is shrinking, with its radius decreasing by 2.7 to 5.6 kilometers due to core cooling. This contraction forms thrust faults and scarps on the surface. A new ...

CAPE CANAVERAL, Fla. — The Hubble Space Telescope has captured the best picture yet of a high-speed comet visiting our solar system from another star. NASA and the European Space Agency released the ...
