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

Earth's core might hold dozens of oceans worth of hydrogen, hinting at the origins of the planet's vast water supply
How Earth got its water has remained an open question for years. Some scientists suspect that much of it came from icy comets that pelted the planet during its youth. But now, new research supports ...
Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...
Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.
The solar system formed approximately 4.5 billion years ago. Numerous fragments that bear witness to this early era orbit the Sun as asteroids. Around three-quarters of these are carbon-rich C-type ...
