A surprisingly mature spiral galaxy named Alaknanda has been spotted just 1.5 billion years after the Big Bang--far earlier than astronomers believed such well-structured galaxies could form. With sweeping spiral arms, rapid star formation, and an .. ...

For thirty years, SOHO has watched the Sun from a stable perch in space, revealing the inner workings of our star and surviving crises that nearly ended the mission. Its long-term observations uncovered a single global plasma conveyor belt inside the ...

Earth's orbit is getting crowded with broken satellites and leftover rocket parts. Researchers say the solution is to build spacecraft that can be repaired, reused, or recycled instead of abandoned. They also want new tools to collect old debris and ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and change their orbital behavior. This leads the stars to ...

A UC Irvine team uncovered a never-before-seen quantum phase formed when electrons and holes pair up and spin in unison, creating a glowing, liquid-like state of matter. By blasting a custom-made material with enormous magnetic fields, the ...

Engineers have unlocked a new class of supercapacitor material that could rival traditional batteries in energy while charging dramatically faster. By redesigning carbon structures into highly curved, accessible graphene networks, the team achieved . ...

Researchers unveiled a new technique that validates quantum computer results--especially those from GBS devices--in minutes instead of millennia. Their findings expose unexpected errors in a landmark experiment, offering a crucial step toward truly . ...

Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from different quantum dots--one of the biggest challenges in building a quantum internet. By creating nearly identical ...

The discovery of strange, ultra-red objects--especially the extreme case known as The Cliff--has pushed astronomers to propose an entirely new type of cosmic structure: black hole stars. These exotic hybrids could explain rapid black hole growth in . ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing new data from NASA's Fermi Gamma-ray Space ...
