One of the oldest known meteor showers is streaking through the sky above California. The Lyrid meteor shower was first recorded in 687 B.C. and has been studied for more than 2,000 years, according to NASA. The meteor shower ...
The origin of life on Earth is still enigmatic, but we are slowly unraveling the steps involved and the necessary ingredients. Scientists believe life arose in a primordial soup of organic chemicals and biomolecules on the ...
Like boulders, rocks, and pebbles scattered across a landscape, asteroids come in a wide range of sizes. Cataloging asteroids in space is tricky because they are faint and they don't stop to be photographed as they zip along ...
Evidence from the fragments of a destroyed asteroid suggests that the shift in the positions of the giant planets in our solar system billions of years ago happened between 60–100 million years after the solar system's ...
Ceres, the largest asteroid in our solar system, harbors a dark secret: extremely young ice deposits in permanently shadowed craters near its poles. If that sounds vaguely familiar, it's because our moon and planet Mercury ...
