Neutrinos are funny little particles that weigh almost nothing, making them one of the universe's most elusive building blocks. They can come from objects as mundane as bananas and as exotic as supernovas—the exploding death throes of massive stars. Most neutrinos stream through space and pass through the Earth without interacting with anything.

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
