Meteors don't just burn up. What really happens is far more violent

Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why meteorites scatter across the gr

Scientists discover a hidden oxygen reservoir deep inside Earth

Scientists have discovered that magma deep inside Earth can store surprising amounts of extra oxygen, potentially revealing a hidden contributor to our planet's oxygen-rich atmosphere. The findings suggest that ancient volcanic eruptions may have helped transform Earth's atmosphe

Enormous 'Cat's Tail' tells of cosmic collision 63 light-years away

Sixty-three light-years from Earth, in the small, faint constellation known as Pictor (which is Latin for "painter"), there lies a strange structure that has puzzled astronomers for the last two years. Nicknamed the "Cat's Tail," this dark feature stretches across an abyss of spa
