Astronomers, anthropologists, geologists, and many other scientists made mind-boggling breakthroughs in 2019.
Some highlights include work that produced the first image of a black hole, traced the origins of modern humans, and predicted future sea-level rise.
These are 22 of the biggest scientific accomplishments of the year.

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 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.

On New Year’s Day, NASA’s nuclear-powered New Horizons spacecraft flew past a mysterious, mountain-sized object 4 billion miles from Earth.
The object, called MU69, is nicknamed Arrokoth, which means “sky” in the Powhatan/Algonquian language (it was previously nicknamed Ultima Thule). It’s the most distant object humanity has ever visited.
The New Horizons probe took hundreds of photographs as it flew by the space rock at 32,200 miles per hour.
Images revealed that Arrokoth is flat like a pancake, rather than spherical in shape. The unprecedented data will likely reveal new clues about the solar system’s evolution and how planets like Earth formed, though scientists are still receiving and processing the information from the distant probe.
