A new study argues that Pop III stars flooded the cosmos with water. Based on this, by 100 to 200 million years after the Big Bang, there could have been enough water and other elements in molecular clouds for life to form.
The computer science behind translating speech from 100 source languages.
Fast radio bursts (FRBs) are puzzling phenomena because their details are so difficult to resolve. Astronomers added another piece to the puzzle with the detection of an FRB that seems to originate in a dead galaxy.
JWST revealed a massive star that ended its life in an explosion when the universe was just a cosmic toddler.
Our digital legacies don’t just preserve memories; they can continue to influence the world, long after we’re gone.
The low levels of gravity (microgravity) in space cause significant changes in astronauts' eyes and vision after six to 12 months aboard the International Space Station (ISS).
The term "pyrocene" suggests a geologic epoch dominated by human-caused fires. Humanity and fire have been reforging the Earth since the end of the last glaciation, about 11,500 years ago.
New data from James Webb Space Telescope and simulation models have confirmed a new type of planet unlike anything found in the Solar System.
The space debris problem won't solve itself. We've been kicking the can down the road for years as we continue launching more rockets and payloads into space.
Winds circling a gas giant more than 500 light years from Earth have been detected flowing at supersonic speeds approaching 33,000 kilometers per hour, making them the fastest air currents on any known planet by a wide margin.
A new measurement confirms what previous - and highly debated - results had shown: The universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of physics.
We know that lakes existed on Mars’ surface billions of years ago. But scientists have debated whether the lakes were open to the air or covered by a layer of ice.
High summer temperatures caused record melting of the Norwegian archipelago’s glaciers.
As far as supermassive black holes go, the one at the center of the Milky Way is relatively sedate. But on 6 April 2024, the black hole let out a flare observed in mid-infrared wavelengths, followed by a radio flare counterpart.
The southern highlands of Mars (which cover about two-thirds of the planet’s surface) rise as much as five or six kilometres higher than the northern lowlands. Nowhere else in the Solar System do we see such a large, sharp contrast at this scale.
