The most energetic "ghost particle" neutrino ever detected may have been blasted at Earth by blazars, suggesting that these events and their black hole engines are powerful cosmic particle accelerators.
Mercury may have gotten much of its polar ice within a single Mercurian day following a massive asteroid impact, a new study suggests.
Fear not, these lasers are just doing science.
Astronomers say that they have identified 20 stars that may have grown up together in a dwarf galaxy named "Loki" that eventually became part of our Milky Way.
NASA envisions its moon base covering hundreds of square miles, and hopping scout drones may mark the facility's perimeter. The agency just awarded $1 billion in contracts to get the ball rolling.
Satellites captured footage of an underwater volcano eruption in a part of the sea that remains largely a mystery.
Researchers analyzing crimson auroras over Japan found the glowing displays stretched hundreds of miles higher into Earth's atmosphere than expected, challenging long-held assumptions about the strength of geomagnetic storms.
Data from NASA's MAVEN spacecraft revealed a never-before-seen atmospheric effect on Mars, revealing how solar storms may shape planets without strong magnetic fields.
