A new breakthrough is transforming MXenes--ultra-thin, high-tech materials--into something far more powerful and precise. Researchers have developed a cleaner, more controlled way to build these materials using molten salts and iodine, eliminating .. ...

Dying stars may be wiping out nearby giant planets as they expand into red giants. Astronomers found that these close-in planets become increasingly rare around more evolved stars, suggesting many have already been swallowed. The likely cause is a .. ...

A group of undergraduate students stumbled into a cosmic time capsule--one of the oldest stars ever discovered--while combing through massive astronomy datasets. What began as a class project quickly turned into a breakthrough when they spotted an .. ...

Asteroid impacts may have helped kick-start life on Earth by creating hot, chemical-rich environments ideal for early biology. These impact-generated hydrothermal systems could have lasted thousands of years--long enough for life's building blocks to ...

Saturn's magnetic field isn't the smooth, symmetrical shield scientists see around Earth. Instead, it's noticeably skewed, and researchers now think they understand why. By analyzing years of data from the Cassini spacecraft, scientists found that a ...

A new concept suggests SpaceX's Starship could revolutionize a future mission to Uranus, one of the solar system's most overlooked planets. By refueling in orbit and helping slow the spacecraft on arrival, it could cut travel time nearly in half. ...

A new breakthrough in wireless technology could dramatically boost internet speeds while cutting energy use--by switching from radio waves to light. Researchers have developed a tiny chip packed with dozens of miniature lasers that can transmit ...

Fusion scientists have solved a long-standing mystery inside tokamaks, the donut-shaped machines designed to harness fusion energy. For years, experiments showed that escaping plasma particles hit one side of the exhaust system far more than the ...

A new era of lunar exploration has begun as NASA launches four astronauts on Artemis II--the first crewed mission to fly around the Moon in over 50 years. Riding aboard the powerful SLS rocket, the Orion spacecraft is now on a 10-day journey that ...

Scientists have unveiled a new approach to ultra-secure communication that could make quantum encryption simpler and more efficient than ever before. By harnessing a 19th-century optics phenomenon called the Talbot effect, researchers developed a ...
