NASA and SpaceX have delayed Crew-13 after finding an oxidizer leak in the Dragon spacecraft's propulsion system during prelaunch preparations. Engineers are investigating the problem before the four-person crew can begin its journey to the ...

Scientists have uncovered hidden complexity inside two ultrathin superconductors that seemed much simpler than they really are. Niobium diselenide and tantalum disulfide appeared to have a single superconducting state, but highly sensitive ...

Physicists have demonstrated a new way to entangle distant quantum bits without the constant measurements and active control normally required. The team created a "quantum bath," a shared environment filled with correlated microwave photons that ...

NASA's Roman Space Telescope has launched on a million mile journey to L2, where it will scan huge portions of the cosmos for clues about dark matter, dark energy, and distant worlds. With survey speeds roughly 1,000 times faster than Hubble and a .. ...

Rocky planets may have been able to start forming just 100 million years after the Big Bang, thanks to enormous early supernovae that scattered planet-building elements across space. Simulations found enough solid material and water around a young .. ...

Diamond was thought to be incapable of producing electricity through mechanical deformation, but ultrathin flexible diamond membranes have now shown a strong and repeatable piezoelectric effect. The unexpected discovery could open the door to diamond ...

Physicists have mathematically captured a bizarre "spacetime crystal" that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many ...

IBM and University of Chicago researchers have completed a quantum computation that leading classical methods could not practically reproduce. The system used 70 error-corrected logical qubits and finished the task in roughly 15 minutes while also .. ...

Mars has a hidden temperature divide, with its southern interior potentially hundreds of degrees hotter than the north and partially molten. The discovery could help explain several long-standing Martian mysteries, including unusual magnetism, ...

Scientists have cracked a long-standing chemistry problem, creating nanocrystals from tough metal nitrides that were previously extremely difficult to produce at this scale. The breakthrough could turn familiar materials used in LEDs, implants, and . ...
