Satellite data, algorithms can help predict volcanic eruptions
Satellite radar and algorithms can be used to determine when a volcano is on the verge of an eruption. Interferometric synthetic aperture radar images can show ground movement at volcanoes and an […]

New image offers closer view of interstellar object
Astronomers used the W.M. Keck Observatory’s Low-Resolution Imaging Spectrometer to take a new image of 2I/Borisov, the second interstellar object ever observed passing through our solar system. The image shows the coma […]

Clues point to possible fifth fundamental force
Physicists say they’ve gathered more evidence that there could be a fifth physical force in addition to gravity, electromagnetism and a pair of nuclear interactions. The researchers say they’ve glimpsed a force carried […]

Hayabusa2 on its way back to Earth with asteroid material
Japan’s Hayabusa2 has left the asteroid Ryugu and is on its way back to Earth, bringing with it samples of subsurface material. The spacecraft will return sometime at the end […]

The remains of 14 woolly mammoths have been found in pits in Mexico dug about 15,000 years ago by humans, according to officials with the National Institute of Anthropology and History. “[The […]

AI outplays most humans in StarCraft II video game
An artificial intelligence developed by tech firm DeepMind is better at playing the strategic video game StarCraft II than most human players, and its prowess is detailed in a study published […]

Unexpected extra digit found on aye-aye lemur
The already unusual aye-aye lemur has revealed another secret to researchers — a spare thumb hidden in its palm. Over time, the animals became so adept at tap foraging, they lost their ability […]

Moon has relatively recent ice deposits
Researchers say most of the ice on the moon’s south pole is more than 3 billion years old, possibly produced by volcanoes or asteroids, and younger ice deposits may have come from meteorites or […]

Voyager data measure higher pressure at fringes of solar system
The Voyager probes have provided NASA scientists with data that suggest the pressure at the outer edges of our solar system is much higher than previously believed. Astronomers also discovered […]

Gene editing gives fruit flies monarch abilities
Researchers have edited the genes of fruit flies to make them able to digest the toxins in milkweed like monarch butterflies do. It took just three genetic tweaks to give the fruit flies […]
