For years, the James Webb Space Telescope has been spotting enormous black holes in the early universe that defy all ...

How many electrons are there in the Universe? One bold theory suggests that there could only be one, although this theory has ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

Solar storms are eruptions that release some of the energy stored in the sun's strong magnetic field. These can create intense, localized explosions called solar flares, or much more powerful and ...

In A Nutshell A black hole in the early universe is eating 13 times faster than a classic physics rule says is possible It’s ...

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the ...

Combining observations from several powerful telescopes, astronomers have detected a gargantuan, 'wobbling' black hole ...

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

From planet-scorching stellar outbursts to cataclysms so powerful they shiver the very fabric of spacetime, these are some of the biggest blasts our cosmos has to offer ...

Known as dinosaur stars for both their primeval nature and their immense size, Population III stars existed only when the ...

For forty years, the “Standard Model” assumed dark matter must be cold. If it moved too fast (which would have made it hot), ...

After the Big Bang, the Universe entered a long, dark period before the first stars formed. During this era, hydrogen emitted a faint radio signal that still echoes today. New simulations show this ...
