NASA said Mars meteorite ALH84001 held fossils in 1996. Set beside Perseverance's 2025 Cheyava Falls find, it shows what any Mars life claim must now survive.

Saturn's main rings span about 273,600 km yet are typically only 10 meters thick. Run the math and the famous paper comparison undersells them by a factor of roughly 10,000.

"Pluto is roughly twenty times farther away, yet BepiColombo needed eight years to reach Mercury. The culprit is braking, not distance, and it makes Mercury costlier to reach than Pluto.

Thousands of dehydrated tardigrades crashed into the Moon aboard Beresheet in 2019. The impact physics says they died — and a tun with no liquid water to revive in was never alive anyway.

Asteroid 2025 PN7 has shadowed Earth since roughly 1955 — but it is a quasi-moon, not a second moon. How a 19-metre rock hid for 70 years, and why the dates disagree.

In 1859 a solar storm set telegraph wires on fire and lit auroras over the tropics. The unsettling part is how much more we have to lose if it happens again.

JWST picked up a possible dimethyl sulfide signal on K2-18b — but a tentative, contested 3-sigma whisper is not confirmed alien life. Here is what the data actually shows.

JWST built the sharpest map yet of the universe's invisible dark matter scaffolding. Here's what it actually shows, what the headlines got wrong, and why depth beat width.

A radio burst arrived with nine evenly spaced peaks, like a cosmic metronome. The obvious explanation was a transmitter. The real one is far stranger — and entirely natural.

Mars was never a dead rock. NASA's MAVEN orbiter, declared lost in June 2026, caught the Sun stripping Mars's air in the act — and tied that theft to vanished oceans.

The Moon sits just 1.3 light-seconds from Earth — close enough to talk to, far enough that every Apollo conversation carried a built-in 2.6-second pause.

A YouTuber building a replica helped scientists crack the Antikythera mechanism's last great mystery. Here's what the 2,000-year-old eclipse computer can now tell us.

For the first time, the James Webb Space Telescope has directly characterized the surface of a rocky exoplanet, and what it found is a dark, basalt-covered world with no atmosphere — eerily similar to the Moon.

NASA's James Webb Space Telescope detected methane and carbon dioxide in the atmosphere of K2-18b — a temperate sub-Neptune 120 light-years away that may harbor a global ocean.

NASA's Dragonfly rotorcraft launches in 2028 toward Saturn's moon Titan — a world with methane lakes, a buried ocean, and chemistry that mirrors early Earth.

Gamma Cassiopeiae blazed with X-rays 40 times stronger than expected for half a century. In 2026, the XRISM space telescope finally unmasked the hidden culprit: a ravenous white dwarf.

The SMILE satellite is set to launch May 19, 2026, and will capture the first-ever global X-ray image of Earth's magnetosphere — the invisible shield that keeps life on Earth alive.

NASA's Perseverance rover has uncovered wave-formed beaches and carbonate-rich rocks in Jezero Crater — the clearest evidence yet that Mars once had a stable, life-friendly lake shore.

JWST data suggests LHS 1140b may be a nitrogen-rich water world with a liquid ocean — making it the most promising habitable-zone exoplanet ever found.

NASA shut off Voyager 1's Low-energy Charged Particles experiment on April 17, 2026. Only two instruments now remain active on humanity's most distant spacecraft.

For the first time since Apollo, humans flew behind the Moon — and witnessed a 57-minute total solar eclipse unlike anything ever seen from Earth.

NASA's Roman Space Telescope shares Hubble's mirror size but captures 100 times more sky in a single shot — poised to map a billion galaxies and reshape what we know about dark energy.

For the first time since Apollo, humans are orbiting the Moon — and seeing its hidden far side with their own eyes. Here's what the Artemis II crew witnessed.

Artemis II sends four extraordinary astronauts around the Moon — the first crewed lunar mission since 1972. Meet the commander, pilot, and mission specialists breaking barriers in deep space.

Voyager 1 has been flying through interstellar space for nearly 50 years powered by just 69 KB of memory and a physical tape recorder — less computing power than a digital watch.

In 2022, NASA slammed a spacecraft into an asteroid expecting a nudge. What happened next rewrote the rules of planetary defense forever.
