Life on Earth may exist thanks to an incredible stroke of luck — a chemical sweet spot that most planets miss during their formation but ours managed to hit.

The wonders of life on Earth are endless, but all that may never have come to pass were it not for the planet having the perfect amount of oxygen at birth.

Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

For the first time, astronomers have successfully observed a planet in the midst of its formation, a groundbreaking achievement that provides invaluable insights into the processes that shape ...

As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

Astronomers have uncovered a planetary system that challenges conventional theories of planet formation. The system likely includes a rocky planet that formed beyond the orbits of its gaseous ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that ...

Image of the young nearby 2MASS1612 system (also known as: RIK113) taken with the ESO Very Large Telescope in Chile. The image uses near infrared light that was scattered of the dust particles ...
