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 . ...

Quantum mechanics and Einstein's theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them. A new theoretical framework suggests that some experiments that appear to show gravity behaving quantum ...

Researchers have discovered a way to turn notoriously difficult-to-recycle PVC plastic into a key ingredient used in high-performance lubricants such as engine oil. The technique could give mountains of plastic waste a valuable second life while ...

A major new analysis challenges recent claims that the universe's expansion is slowing, finding that the evidence for cosmic acceleration remains strong. The findings preserve the leading role of dark energy, while leaving scientists with the ...
