It’s a conundrum.” ...

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. A new study shows that Earth formed under ...

A new NASA study reveals a surprising way planetary cores may have formed—one that could reshape how scientists understand the early evolution of rocky planets like Mars. Conducted by a team of ...

A recent astronomical discovery has shaken long-held beliefs about how planets form. For decades, scientists thought that stars much smaller than our Sun couldn't form giant planets. That theory just ...

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 ...

An international collaboration including researchers from Lawrence Livermore National Laboratory has discovered that the Earth’s core formed under more oxidizing condition’s than previously proposed.

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS 1903 is an ancient star, around seven billion years old, and only has about ...

New research from ETH Zurich challenges the long-held “follow the water” rule in the search for extraterrestrial life. Scientists argue that a planet’s habitability depends on a narrow chemical ...
