It’s hard to say which scientist was the first to set eyes on the glowing ring that makes up the world’s first image of a black hole. But astrophysicist Kazunori Akiyama was certainly one of the earliest. The image, released to the public on April 10, revealed the dark shadow of the supermassive black hole […]

Israel’s first lunar lander, Beresheet, appears to have crash-landed on the moon. The spacecraft, launched by the Israeli nonprofit SpaceIL, was scheduled to touch down on the lunar surface on April 11. But in the final few minutes of its descent, the spacecraft’s engine stalled. Mission control reset Beresheet to bring its engine back online, […]

Black holes capture everything they encounter. From subatomic particles to stars, solids, gases, liquids and even light, everything falls irretrievably in. And even more assuredly, black holes capture the popular imagination. Thinking about space, as humans have since they first gazed at the points of light decorating the nighttime sky, triggers the mind to imagine […]

A new peek at the genetics of beetle genitals reveals the underpinnings of a battle of the sexes. When mating, males of Japan’s flightless Carabus beetles insert a chitin-covered appendage that, once inside a female, pops out a plump sperm-delivery tube as well as a side projection called a copulatory piece. That piece doesn’t deliver […]

Over 100 hours of scanning has yielded a 3-D picture of the whole human brain that’s more detailed than ever before. The new view, enabled by a powerful MRI, has the resolution potentially to spot objects that are smaller than 0.1 millimeters wide. “We haven’t seen an entire brain like this,” says electrical engineer Priti […]

Divers monitoring coral reefs off St. Thomas in the U.S. Virgin Islands in January noticed something alarming: Big white lesions were eating into the colorful tissues of hundreds of stony corals. Some corals were dead by the next day — only their stark white skeletons remained. Others languished for up to two weeks. Within four […]

From the beginning, the moon has been humankind’s perpetual nighttime companion. Accompanied by innumerable points of light, the moon’s luminous disk hovered overhead like a dim substitute for the sun, just with a shape not so constant. Rather the moon waxed and waned, diminishing to a barely discernible sliver before disappearing and then gradually restoring […]

The Hayabusa2 spacecraft has made its second and final attempt to grab a pinch of dust from asteroid Ryugu. At about 9:06 p.m. EDT on July 10, the Japanese spacecraft briefly touched down near an artificial crater it had previously blasted into the 4.5-billion-year-old asteroid’s surface. If the dust grab went well, it’s the first […]

There once was a little bird, smaller than a sparrow, that lived about 99 million years ago. And it had a freakishly long toe. Researchers found the ancient bird’s right leg and foot preserved in a chunk of amber. Its third digit is 9.8 millimeters long, about 41 percent longer than its second-longest digit — […]
