How Cold War Scientists Designed a Starship That Could Reach Another Sun
Scientists and engineers have long dreamed of using fusion-powered spacecraft to reach other star systems within a human lifetime. Concepts first explored during the Space Age and Cold War era proposed that fusion drives could generate enough thrust to make interstellar travel feasible. Many of those original ideas remain under consideration today, waiting for technological breakthroughs to finally bring them to life.
Curiosity Rover Stumbles Upon a Breathtaking Sea of Honeycomb Patterns on Mars
NASA’s Curiosity rover has photographed unusual honeycomb-like patterns on the surface of Mars. The geometric shapes, known as polygonal fractures, measure between 1.5 and 3 inches wide. Scientists have been studying the formations to better understand their size and structure, offering new insights into the geological history of the dry, desert planet.
The Galaxy’s Most Common Planet Is One Our Solar System Somehow Never Made
A Universe Full of Worlds We’ve Never Seen Up Close Thirty years ago, we knew of not a single confirmed planet orbiting another star. Not one. Today, that tally has surpassed 6,000 — and it keeps climbing week by week. That alone would be a…
A Giant Iceberg Cracked Open Antarctica and Revealed a Secret Fish City
A Window Into the Unknown In a secluded section of Antarctica’s western Weddell Sea, researchers have made an extraordinary discovery in an area once concealed beneath 200 meters of solid ice — vast, organized fields of fish nests, carefully maintained and arranged in striking patterns….
On Mars, Spring at Your Feet and Winter at Your Head at the Same Moment
Mars’s extremely thin atmosphere creates dramatic temperature differences across incredibly short distances. Near the equator around midday, sunlit ground can reach 24 degrees Celsius while the air just a few feet higher stays below freezing. This means a person standing on the surface could simultaneously experience spring-like warmth at their feet and bitter cold at their head, a phenomenon impossible on Earth.
The Perseid Meteor Shower Peaks August 12 With Rare Perfect Conditions
The Perseid meteor shower is set to peak on August 12 and 13, offering one of the best stargazing events of the summer. The Perseids are widely considered one of the most spectacular annual meteor showers, known for producing bright, fast-moving meteors. Clear skies and minimal light pollution will offer the best viewing conditions for sky watchers.
Jupiter’s Gravity Is Keeping an Alien Ocean Liquid — And It’s Bigger Than All of Earth’s Seas
A Hidden Ocean Hiding in Plain Sight There is a world in our solar system that holds more liquid water than every ocean on Earth combined. It isn’t a planet. It isn’t even particularly large. Europa is about 3,100 kilometers across — roughly 90 percent…
A Dead SpaceX Rocket Is About to Strike the Moon at 5,400 Miles Per Hour
A Year of Drifting, Then Impact A spent SpaceX Falcon 9 upper stage will crash into the Moon on Wednesday, August 5, hitting near Einstein Crater at 5,400 mph. It’s not a mission, and nobody planned it. It’s a leftover chunk of rocket that has…
The Silent War Above Us — How Satellites Became the New Battleground
The First Shot Was Already Fired At 3:00 a.m. on February 24, 2022, thousands of satellite modems across Ukraine and Central Europe went offline. A few hours later, Russia’s invasion of Ukraine began. Most people remember that day as the start of a ground war….
How Rats on Tropical Islands Are Quietly Dismantling Coral Reef Ecosystems
A Chain Reaction Spanning Land and Sea It sounds like an unlikely connection: rats living on a remote tropical island dictating which fish thrive on a nearby coral reef. But a striking new study has revealed exactly that kind of long-distance ecological domino effect, tracing…
