Black holes are fascinating regions in space where gravity is so strong that nothing, even light, can escape them. The largest known black holes, called supermassive black holes, contain millions to billions of times the ...
Scientists in China predict that stacking two microscopic layers of boron could set a new record for superconductivity. Superconductors are materials that conduct electricity with zero resistance. Traditional types need temperatures ...
Federal officials said Thursday they will not release cool water this year from one of the Colorado River's major reservoirs, which would have protected a threatened native fish downstream but put more strain on already struggling ...

A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of "leaky" galaxies was responsible for cosmic reionization. The paper outlining this work ...
Groundwater pumped to irrigate cannabis crops in California's Emerald Triangle can cause some streams that normally run year-round to dry up entirely during summer, say researchers from Simon Fraser University, the University ...

Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked ...
Named for the mythical valley where the god Dionysus was raised in secret by nymphs, the asteroid 44 Nysa inhabits the asteroid belt between Mars and Jupiter. Through observations by the Hubble Space Telescope, astronomers ...
