Bubble-blowing galaxies could help solve a cosmic mystery
Three galaxies ionizing hydrogen 680 million years after the Big Bang show a potential step in the ionization of nearly all hydrogen in the cosmos.

The home galaxy of a second repeating fast radio burst is a puzzle
The second galaxy known to host brief, brilliant flashes of radio waves known as a recurrent fast radio burst looks nothing like the first.

LIGO detects its second neutron star collision, but gains few clues
Gravitational waves have once again heralded a smashup between neutron stars, but this time with no flash of light to help guide understanding.
- Space
The first glimpses of a pulsar’s surface hint at complex magnetism
Maps of a rapidly spinning neutron star could eventually help researchers figure out how matter behaves at extraordinarily high densities.
- Space
A new map reveals radio waves from tens of thousands of galaxies
Radio waves from about 17,000 galaxies show that the peak of star formation, about 10 billion years ago, might have been more productive than predicted.

How 2019’s space missions explored distant worlds
Planets and asteroids and Arrokoth, oh my. Space probes had a busy year.

50 years ago, scientists didn’t know where heavy elements came from
Five decades ago, scientists suspected ordinary supernovas created heavy elements. Now we know they don’t, but merging neutron stars do.
- Space
A new mission to investigate exoplanets has rocketed into space
The European Space Agency’s CHEOPS satellite has launched on a mission to gather intel on previously discovered planets outside of the solar system.

These science claims from 2019 could be big deals — if true
Some of this year’s most tantalizing scientific finds aren’t yet ready for a “best of” list.

2019 brought us the first image of a black hole. A movie may be next
The Event Horizon Telescope team is gearing up for more black hole discoveries.

China stuck its moon landing this year. Others weren’t as lucky
Fifty years after Apollo 11 landed on the moon, Earth’s sidekick is getting renewed attention from space agencies around the world.

NASA’s OSIRIS-REx must avoid ‘Mount Doom’ to return a sample of the asteroid Bennu
The OSIRIS-REx spacecraft finally has a target spot for sample collection, called Nightingale, on the asteroid Bennu.
