Meteorites from Mars contain clues about the red planet's geology

Martian meteorites allow scientists here on Earth to decode that planet's geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.

Pairing lasers with microwaves makes mind-bogglingly accurate electronic clocks – a potential boon for GPS, cell phones and radar

Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.

TRAPPIST-1’s ‘habitable’ planets might be lousy for life

A shower of high-energy particles and nearby planets' gravitational pull may make planets in the "habitable zone" of the TRAPPIST-1 system anything but.

Harvard scientists shed light on importance of black hole image

Researchers at the Event Horizon Telescope (EHT) just unveiled the first-ever image of a black hole, which captures what EHT Director Sheperd Doeleman called “a one-way door from our universe.”
