A record-breaking temperature has stood for over a century, but the scientists who know it best think it probably never happened.
After twenty years of drilling through Soviet rock, scientists had barely scratched the surface—the planet's interior remained as unreachable as the stars.
The question haunting postwar planners was not whether Japan could recover, but whether it would starve before it had the chance.
A single Australian telescope holds humanity's only conversation with a spacecraft that left Neptune decades ago—until Earth's repair needs force an impossible silence.
The world's most abundant building material is running scarce in the places that need it most.
A single human fingerprint contains 300 times more organic material than Mars's most precious cargo is allowed to carry—and NASA's engineers had to invent new ways to keep these tubes pristine enough to preserve signs of ancient microbial life.
The eclipse that darkens Iceland and Spain gives American observers a notch out of the Sun, in the morning in Alaska and around midday farther east. The better event arrives after midnight.
Researchers in Uttarakhand described a new spider, Theridion himalayana, carrying the red-and-black smile that made Hawaii's happy-face spider famous. A gene barcode sets it about 8.5 percent apart from the Hawaiian species, enough to call it its own lineage. Whether the two arrived at the same face by chance or inherited it from a shared ancestor is the question the discovery leaves open.
An aging star has far more lithium than it should. Astronomers say the likeliest reason is that TOI-5882 swallowed one of its own planets, though they call it a candidate, not a verdict.
Astronomers used Hubble's ultraviolet vision to directly confirm four white dwarfs lost in the glare of nearby red dwarfs, one of them the ninth closest to the Sun.
A vertebrate that freezes solid each winter and wakes without brain damage or organ failure is forcing scientists to reconsider the limits of what a living thing can endure.
A coordinated VLA and MeerKAT campaign sifted more than twenty million radio detections logged while watching the K2-18 system and found nothing that came from the planet. The silence is real, but it rules out only a narrow slice of what a distant civilization might do.
It's a grim but essential test: whether your windshield can withstand a poultry projectile traveling at 560 miles per hour.
For the first time, humanity tested whether it could nudge a killer asteroid out of Earth's path—and the results suggest our planetary insurance policy might actually work.
The solar system's most violent world was hiding in plain sight, its apocalyptic surface mistaken for instrument failure until scientists realized they were witnessing something unprecedented.
The absence of life on a world with all its ingredients could prove as revolutionary as finding it.
