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 ...

Scientists studying Bennu samples have discovered that its chemistry is far from uniform. Organic compounds and minerals cluster into three distinct types of regions, each shaped differently by past water activity. This uneven pattern shows that ...

Scientists have transformed a groundbreaking 2D nanomaterial called MXene into an even more powerful 1D form--tiny scroll-like tubes that are incredibly thin yet highly conductive. By rolling flat sheets into hollow nanoscrolls, they've created ...

DNA robots are emerging as tiny programmable machines that could one day deliver drugs, hunt viruses, and build molecular-scale devices. By borrowing ideas from traditional robotics and combining them with DNA folding techniques, scientists are ...
