It's official. There's water on the Moon.

Asymptomatic coronavirus sufferers appear to lose detectable antibodies sooner than people who have exhibited COVID-19 symptoms, according to one of the biggest studies of its kind in Britain reported on Tuesday.

Passing electricity through a piece of quartz crystal generates a pulse you can literally set your watch by. Set a time crystal melting, on the other hand, and it just might pulse with the deepest secrets of the Universe.

Titan, the already pretty weird moon of Saturn, just got a little bit weirder. Astronomers have detected cyclopropenylidene (C3H2) in its atmosphere - an extremely rare carbon-based molecule that's so reactive, it can only exist on Earth in laborat

NASA said Thursday its robotic spacecraft Osiris-Rex was able to stow a rock and dust sample scooped up from the asteroid Bennu, after a flap that had wedged open put the mission at risk.

Every 200,000 to 300,000 years, Earth's magnetic poles reverse. What was once the north pole becomes the south, and vice versa. It's a time of invisible upheaval.

There are many unanswered questions about our place in the Universe. Why are we here? What is the likelihood of our existence? Could there be others like us out there in the galaxy?
