In 2019, scientists around the world pulled off some impressive feats: They imaged a supermassive black hole for the first time, debuted two treatments for the Ebola virus, and launched a spacecraft into orbit that’s powered by sunlight alone.
Over the past year, researchers have also discovered a hidden continent, captured video of a giant squid in its deep-sea habitat, and sent a probe to an asteroid 5.5 million miles from Earth.
These and other accomplishments are improving scientists’ understanding of our own biology, our planet, and the surrounding cosmos.
As a new year — and a new decade — approaches, here’s a look back at some of the most mind-boggling scientific discoveries from 2019.
