A fast radio burst’s rapid, steady beat offers a clue to its cosmic origin

Amped-up neutron stars, pairs of magnetically entangled neutron stars or magnetar quakes could explain a three-second-long train of radio blips.

Sand clouds are common in atmospheres of brown dwarfs

Dozens of newly examined brown dwarfs have clouds of silicates, confirming an old theory and revealing how these failed stars live.

Aliens could send quantum messages to Earth, calculations suggest

Scientists are developing quantum communications networks on Earth. Aliens, if they exist, could be going further.

An otherwise quiet galaxy in the early universe is spewing star stuff

Seen as it was 700 million years after the Big Bang, the galaxy churns out a relatively paltry number of stars. And yet it’s heaving gas into space.

Gravitational wave ‘radar’ could help map the invisible universe

Gravity ripples scattering off warped spacetime near massive objects might help astronomers peer inside stars and find globs of dark matter.

Seven newfound dwarf galaxies sit on just one side of a larger galaxy

Seven newly found dwarf galaxy candidates are stick to just one side of the large galaxy M81. Astronomers don’t know why.

Neutrinos hint the sun has more carbon and nitrogen than previously thought

Scientists still don’t know the sun’s exact chemical composition, which is crucial for understanding the entire universe. Neutrinos will help.

A celestial loner might be the first known rogue black hole

The object could be the first isolated stellar-mass black hole identified in the Milky Way — or it might be an unusually heavy neutron star.

New Gaia data paint the most detailed picture yet of the Milky Way

Gaia’s new data can tell us about galaxies the Milky Way has swallowed, the young solar system and asteroids that could hit Earth.

A newfound, oddly slow pulsar shouldn’t emit radio waves — yet it does

The highly magnetic neutron star rotates three times slower than the previous record holder, challenging the theorical understanding of these objects.
