The discovery challenges what we thought we knew about animal communication and raises unsettling questions about consciousness in creatures we've long underestimated.
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.
A spacecraft running on 1970s computer chips still transmits data from the edge of interstellar space—a feat of engineering that raises an uncomfortable question about what we've sacrificed for speed.
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.
America's first space station spent six years in orbit before its dramatic demise scattered wreckage across Western Australia—where pieces became museum pieces, souvenirs, and something far more practical.
A machine built when the Beatles had just broken up still explores the cosmos—and NASA engineers still debug it the old-fashioned way.
In the solar system's deep freeze, heat from within may unlock worlds we thought impossible to inhabit.
The first photograph of Earth from space wasn't taken by an astronaut or a satellite, but by a camera strapped to a weapon of war, surviving the very machine that carried it skyward.
The absence of life on a world with all its ingredients could prove as revolutionary as finding it.
A creature so rare that scientists had to film the ocean floor for weeks just to glimpse it for 20 seconds—and what they saw rewrote everything we thought we knew about where it lives.
But the mountain is also sacred to Native Hawaiians, and decades of construction have ignited a battle over who gets to use Earth's most precious viewing platform.
The Southern Delta Aquariids reach their peak around July 30, but a nearly full Moon will wash out all but the brightest meteors. Here is why the dark mornings the week before are the better bet, and why no one is quite sure which comet the shower even comes from.
Earth's bulge at the equator means a volcano in Ecuador sits closer to space than the world's highest peak.
What looks like laziness is actually a predator's metabolic masterpiece: cats need most of their day to fuel the milliseconds when they strike.
