We summarize the week's scientific breakthroughs every Thursday.
- Cosmology
Milky Way’s loner status is upheld
Galaxy surveys show the Milky Way lives in a vast cosmic void, which could help ease tensions between ways of measuring how fast the universe is expanding.
- Astronomy
Einstein’s light-bending by single far-off star detected
A measurement so precise Einstein thought it couldn't be done has demonstrated his most famous theory on a star outside the solar system for the first time.
- Astronomy
Scalding hot gas giant breaks heat records
KELT 9b’s sun blasts it with so much radiation that the planet’s dayside is hotter than most stars and its atmosphere is being stripped away.
- Physics
LIGO snags another set of gravitational waves
Two black holes stirred up the third set of gravitational waves ever detected.
- Particle Physics
Readers puzzled by proton’s properties
Readers sent feedback on under-ice greenhouses in the Arctic, the Martian atmosphere and more.
- Planetary Science
Why you can hear and see meteors at the same time
People can see and hear meteors simultaneously because of radio waves produced by the descending space rocks.
- Planetary Science
Citizen scientists join the search for Planet 9
Backyard Worlds: Planet 9, a citizen science project, lets space enthusiasts search for undiscovered objects in the sky, including a hypothesized planet at the far reaches of the solar system.
- Astronomy
Magnetism disrupts winds on ‘hot Jupiter’ exoplanet
Simulations of HAT-P 7b’s magnetic field give clues to why the exoplanet’s winds blow both east and west.
- Planetary Science
Juno spacecraft reveals a more complex Jupiter
NASA’s Juno spacecraft has sent back unexpected details about Jupiter, giving scientists their first intimate look at the giant planet.
