Physicists observationally confirm Hawking’s black hole theorem for the first time
Study offers evidence, based on gravitational waves, to show that the total area of a black hole’s event horizon can never decrease.
There are certain...
A white dwarf living on the edge
Astronomers have found a stellar corpse often called a white dwarf that’s roughly the scale of Earth’s moon. White dwarfs are the collapsed remnants...
Research sheds light on origins, age of massive impact crater
New research suggests that the Hiawatha impact crater beneath ice could have been formed during the Pleistocene geological epoch. The 31-kilometer-wide crater first came to the world's attention in 2018 when...
Physicists ‘squeeze’ light to cool microscopic drum below quantum limit
NIST researchers applied a special form of microwave light to cool a microscopic aluminum drum to an energy level below the generally accepted limit,...

Universe’s first life might have been born on carbon planets
In this artist's conception, a carbon planet orbits a sunlike star in the early universe. Young planetary systems lacking heavy chemical elements but relatively...
‘Wasteful’ galaxies launch heavy elements into surrounding halos and deep space
Spiral galaxies like the Milky Way are shown in the center, surrounded by the circumgalactic medium, which appears as black to our eyes. However,...
The universe is expanding even faster than expected
This illustration shows the three steps astronomers used to measure the universe's expansion rate to an unprecedented accuracy, reducing the total uncertainty to 2.4...

An international team of scientists has pushed the limits of radio astronomy to detect a faint signal emitted...
Hubble finds clues to the birth of supermassive black holes
This artist's impression shows a possible seed for the formation of a supermassive black hole. Two of these possible seeds were discovered by an...
