Scientists exploring an underwater region off the coast of Alaska discovered an ancient stone fish trap that may be the oldest ever found. University academics working with the Sealaska Heritage Institute (SHI) made the find earlier this year in Shakan Bay on the west side of Prince of Wales Island while using artificial intelligence to…
A Chinese rocket booster plummeted to Earth on Friday morning, falling into the Pacific Ocean. The U.S. Space Command reported that the debris from the Long March 5B rocket re-entered Earth’s atmosphere over the south-central Pacific Ocean at 4:01 a.m. MDT. Later, the agency said it could confirm a second atmospheric entry correlated with the…
A large “potentially hazardous asteroid” is expected to swing fewer than six lunar distances from Earth at the beginning of next month. The asteroid, known as 2022 RM4, is expected to pass by Earth on Nov. 1 – about 1.5 million miles away at its closest point. According to NASA’s Center for Near Earth Object…
The last solar eclipse of the year was visible on Tuesday across Europe, Asia and Africa. The partial solar eclipse started shortly before 5 a.m. EDT and ended a minute after 9 a.m. At its maximum point, 82% of the sun was eclipsed by the moon. During a partial solar eclipse, it looks as if…
Scientists have discovered a massive “galactic underworld” filled with corpses of former suns turned black holes and neutron stars. Moreover, the galactic graveyard is three the height of the Milky Way, and much of the remnants are three times larger than our own sun. The findings were published in Monthly Notices of the Royal Astronomical…
The NASA Double Asteroid Redirection Test (DART) spacecraft on Monday deliberately slammed into an asteroid millions of miles away in an innovative test for a possible killer rock that could one day be headed to Earth. NASA described the mission as an “impact success,” saying the “vending machine-sized spacecraft” collided with the asteroid Dimorphos, which…
A Chinese rocket fell back to Earth on Saturday environment, but NASA said Beijing had not shared the “specific trajectory information” needed to know where possible debris might fall. U.S. Space Command said the Long March 5B said the rocket re-entered over the Indian Ocean at approximately 12:45 p.m. EDT Saturday (1645 GMT), but referred…
NASA air-and-space to Mars in its effort to return Martian rocks and soil samples to Earth. Under the plan announced Wednesday, NASA’s Perseverance rover will do double duty and transport the cache to the rocket that will launch them off the red planet a decade from now. Perseverance already has gathered 11 samples, with more…
New York researchers transplanted pig hearts into two brain-dead people over the last month, the latest in a string of developments in the long quest to one day save human lives with animal organs. The experiments announced Tuesday come after a historic but failed attempt earlier this year to use a pig’s heart to save…
A mummified baby woolly mammoth more than 30,000 years old has been world-regions in what authorities are hailing as the “most complete” discovery of its kind. The remains of the female calf, named “Nun cho ga” in the Hän language – which translates to big baby animal – was found by miners on June 21 in…
