Here in our Universe, there’s a big puzzle at the heart of every black hole. According to Einstein’s general relativity, for every black hole that exists within the Universe, there are only three properties that go into it that matter in any way: the black hole’s total mass, the black hole’s net electric charge, and
Imagine a baby Brachiosaurus no bigger than a golden retriever searching for plants alongside its siblings while trying to avoid predators eager for an easy meal. Far away, its parents, towering more than 40 feet tall, continue their lives with no direct involvement in the youngster’s daily survival. Thomas R. Holtz Jr., a principal lecturer
NASA’s Curiosity rover has captured close‑up views of sprawling, web-like rock formations on Mars that look like giant spiderwebs from orbit and may offer new clues about the Red Planet’s watery past. The intricate formations are part of a boxwork region — networks of low ridges roughly 3 to 6 feet (1 to 2 meters)
You’ve got a legitimate reason to flinch when you’re peeling off a roll of Scotch tape. That annoying screech is actually tiny cracks traveling at supersonic speeds. An international team of physicists used high-speed cameras and sensitive microphones to capture ordinary Scotch tape as it peels away from its roll, identifying a train of shock
NEW YORK — A blood-red moon will soon grace the skies for a total lunar eclipse — and there won’t be another until late 2028. The spectacle will be visible Tuesday morning from North America, Central America and the western part of South America. Australia and eastern Asia can catch it Tuesday night. Partial stages
The outer curvature endures great strain: Located directly opposite the valve through which blood enters the heart, it gets hit with incoming blood. Researchers presumed that certain genes were more active in this part of the heart, and that this activity explained the formation of the muscular network of trabeculae. But when Priya and her
Mars is now a cold, radiation-battered world. Yet a broad body of evidence shows that billions of years ago, liquid water flowed across its surface. That wetter past has long fueled the idea that life may once have taken hold before the planet lost its atmosphere. Back on Earth, some of the harshest landscapes mirror
For decades, scientists have delved into the genetic causes of disease by studying patients with those diseases and their families, picking through their genomes in search of genetic mutations that could be the cause. It’s a method that has turned up hundreds of mutations, many thought to be responsible for diseases in almost 100% of
In early November 2025, Chinese astronauts aboard the Tiangong space station made a shocking discovery that could have altered the trajectory of their mission. Initially, reports from state news agencies suggested the damage to the spacecraft’s viewport was minimal, likely caused by a collision with space debris. However, recent revelations shed light on the true
A new study published in PLOS One sheds new light on early human intelligence by revealing that 60,000-year-old ostrich eggshell fragments from southern Africa bear intricate geometric markings. These designs offer an astonishing glimpse into the advanced cognitive abilities of prehistoric humans, challenging the long-held notion that early humans were far removed from sophisticated thought
