Atomic clocks, combined with precise astronomical measurements, have revealed that the length of a day is suddenly getting longer, and scientists don't know why. This has critical impacts not just on our timek…
Using machine learning, a computer model can teach itself to smell in just a few minutes. When it does, researchers have found, it builds a neural network that closely mimics the olfactory circuits that animal brains use to p…
Explorers have discovered a series of mysterious, "perfectly aligned" holes punched into the seafloor roughly 1.6 miles (2.6 kilometers) beneath the ocean surface, and they have no idea who or what made them. …
A huge sunspot on the far side of the sun is set to face Earth this weekend, potentially lashing our planet with a geomagnetic storm. The spot is so big it's changing the way the sun vibrates, according to sp…
Even though it hasn't been collecting data for very long, the James Webb Space Telescope keeps breaking its own records for peering deeper into space and time. The telescope has now detected a galaxy candidate that lies 35 …
Physicists have just caught light acting the part of 'glue' between atoms, in a kind of loosely bonded molecule. "We have succeeded for the first time in polarizing several atoms together in a contr…
Scientists have recorded Earth's shortest day since its rotational period began to be recorded with highly precise atomic clocks: On June 29, 2022, Earth's spin was completed in 1.59 milliseconds under 24 hours. …
An asteroid wider than two football fields will zoom past Earth in the wee hours of Thursday (Aug. 4). The asteroid is set to pass at 12:23 a.m. (ET). NASA astronomers discovered the asteroid, known as 2022 OE2, jus…
