We summarize the week's scientific breakthroughs every Thursday.
- Space
Jupiter’s icy moon Europa may glow in the dark
Europa’s potential “ice glow” could help scientists map the chemical composition of its surface — and the ocean underneath.
- Space
The Milky Way makes little galaxies bloom, then snuffs them out
When dwarf galaxies cross the Milky Way’s frontier, our galaxy compresses their gas, sparking star birth, but then robs them of their star-making gas.
- Space
Jupiter may host atmospheric ‘sprites’ or ‘elves’ never seen beyond Earth
For the first time, NASA’s Juno spacecraft may have spied the bright, superfast light show on another world.
- Physics
LIGO and Virgo’s gravitational wave tally more than quadrupled in six months
Scientists report 39 sets of spacetime ripples from just half a year of data.
- Planetary Science
Doubts over a ‘possible sign of life’ on Venus show how science works
Detecting phosphine in Venus’ atmosphere made headlines, but reanalyses and new searches call into question the original discovery of the molecule.
- Space
Water exists on sunny parts of the moon, scientists confirm
New observations of the moon, made by a telescope flying onboard a Boeing 747-SP jet, have confirmed the presence of water on sunlit areas of the moon.
- Space
NASA’s OSIRIS-REx survived its risky mission to grab a piece of an asteroid
NASA’s OSIRIS-REx spacecraft just tried to grab a piece of asteroid Bennu. If successful, the spacecraft will return the sample to Earth in 2023.
- Astronomy
Turning space images into music makes astronomy more accessible
Music created from telescope data helps people with blindness and visual impairments experience the wonders of astronomy, and could aid research.
- Space
A spherical star cluster has surprisingly few heavy elements
A globular cluster in the nearby Andromeda galaxy challenges conventional wisdom about how galaxies form.
- Space
The asteroid Bennu’s brittle boulders may make grabbing a sample easier
NASA’s OSIRIS-REx spacecraft is about to collect a bit of asteroid Bennu. Here’s why it’s good that new research suggests its boulders are brittle.
- Space
The first black hole image helped test general relativity in a new way
The Event Horizon Telescope’s iconic image of the black hole at the center of galaxy M87 once again shows Einstein was right.
- Astronomy
The Milky Way’s most massive star cluster may have eaten a smaller cluster
Observations of newfound stars suggest how the gathering of stars at the galaxy’s core grew so big.
