Scientists have discovered that the target asteroid of NASA’s Double Asteroid Redirection Test (DART) may have been reshaped by the impact. A new investigation into the collision’s aftermath revealed that the asteroid, which is the smaller component of a binary asteroid system, exhibits a loose “rubble-pile” composition. DART slammed into the moonlet Dimorphos, which orbits … Read more
Within the next few decades, NASA aims to land humans on the Moon, set up a lunar colony and use the lessons learned to send people to Mars as part of its Artemis program. While researchers know that space travel can stress space crew members both physically and mentally and test their ability to work … Read more
The solar system holds many secrets that scientists are still trying to unravel. To help shed light on these mysteries, researchers are turning to space rocks of all kinds that may hold clues to the lost story of our solar system’s past. This approach is already bearing fruit: In October 2023, NASA’s OSIRIS REx mission … Read more
Scientists have spotted the brightest and fastest-growing quasar ever seen — a monster black hole that’s devouring a sun’s-worth of material every day. The brightly burning object, named J0529-4351, weighs between 17 billion and 19 billion solar masses and is located 12 billion light-years from Earth — meaning it dates to a time when the … Read more
Scientists are working to build blood vessels from human cells using tiny ice sculptures — these frigid 3D forms twist and branch like real arteries and can be used as temporary scaffolds that later get melted away, to be replaced by living cells. The researchers demonstrated the first step of this blood-vessel-building process in a … Read more
Researchers have discovered four gigantic seamounts towering above the seafloor surrounding South America after detecting “gravitational anomalies” given off by the massive underwater mountains. The tallest rises more than 1.5 miles (2.4 kilometers) from the seafloor, making it three times taller than the world’s tallest building Scientists aboard the Schmidt Ocean Institute’s Falkor (too) research … Read more
Scientists are now inspecting snagged, bagged and tagged bits and pieces from asteroid Bennu, the cosmic mother lode delivered by NASA’s Origins, Spectral Interpretation, Resource Identification and Security — Regolith Explorer mission. Known in acronymic astro-speak as OSIRIS-REx, that seven-year-long voyage brought home the goods via a sample return canister that came to full stop … Read more
A puppy has spontaneously regrown his jawbone after part of it was surgically removed because of a cancerous tumor. It is believed to be the first reported case of a dog regenerating its mandible. Veterinarians at Cornell University College of Veterinary Medicine’s Dentistry and Oral Surgery Service first diagnosed Tyson, a 3-month-old French bulldog, with … Read more
A new study has claimed that we may breach the 2 degrees Celsius (3.6 degrees Fahrenheit) climate change increase threshold by the late 2020s — almost two decades earlier than current projections. The study, published Feb. 5 in the journal Nature Climate Change, claims global surface temperatures had increased by 1.7 C (3 F) above … Read more
A malicious technology can trick self-driving cars into “hallucinating” phantom vehicles and veering dangerously off-course to get out of their way, researchers have discovered. The new hack, dubbed “MadRadar,” can also hide real cars from on-vehicle radar sensors and fool a self-driving car into thinking a real car has jerked off course. The scientists reported … Read more
