Why Alien Signals Might Be Hiding in Plain Sight, Scrambled by Their Own Stars
Scientists at the SETI Institute have discovered that stars may be blurring out radio signals from other civilizations before those signals ever reach us. The finding could reshape how we listen for life beyond Earth.
How a Planet-Wide Dust Storm on Mars Silenced NASA's Most Resilient Rover
Built to last 90 days, the Opportunity rover survived on Mars for nearly 15 years — until a dust storm so massive it swallowed the entire planet finally cut off its power supply.
MOXIE Made Oxygen on Mars — Here Is Why That Small Machine Is a Giant Deal
A microwave-sized device aboard NASA's Perseverance rover spent two years quietly making breathable air on Mars, proving a technology that could one day bring astronauts home from the red planet.
Spinning Black Holes Might Actually Send Messages Back in Time
A new study inspired by the film Interstellar explores how information could travel backward through time using exotic loops in spacetime near spinning black holes. The physics is real, even if the idea feels like science fiction.
Saturn Was Not Changing Its Spin — Its Aurora Was Tricking Scientists All Along
A mystery that puzzled astronomers for decades has finally been cracked. Saturn's aurora was creating a self-powered cycle of heat, wind, and electricity that made the planet appear to spin at different speeds.
NASA's Roman Telescope Could Discover 100,000 Exoplanets and Rewrite Planetary Science
A powerful new NASA telescope is preparing to search deep into the Milky Way, hunting for planets in ways no mission has tried before. The results could change everything we think we know about how worlds are born.
NASA Is Building a Computer Chip That Could Let Spacecraft Think on Their Own
NASA's powerful new space processor is 500 times faster than current spacecraft chips — and it could help robots and spacecraft make decisions millions of miles from Earth.
Why Astronauts on the ISS Are Aging Slightly Slower Than You Right Now
The International Space Station travels so fast that time genuinely slows down aboard it — and the proof shows up in GPS satellites and a famous experiment involving twin astronauts.
From Absolute Nothing to Everything: How the Big Bang Created the Universe
The Big Bang was not an explosion in space — it was the birth of space itself. Here's what scientists actually know about the moment the universe began 13.8 billion years ago.
Scientists Found Stars That May Be the Remains of a Galaxy the Milky Way Absorbed Billions of Years Ago
A team of astronomers identified 20 unusually old stars near the center of our galaxy that may be the leftovers of an ancient dwarf galaxy nicknamed Loki — swallowed by the Milky Way over 10 billion years ago.
