We summarize the week's scientific breakthroughs every Thursday.

EHT data show turbulence makes the glowing ring around M87’s black hole wobble
Event Horizon Telescope data spanning nearly a decade reveal that the appearance of the supermassive black hole inside galaxy M87 changes over time.
- Space
Stellar winds hint at how planetary nebulae get their stunning shapes
Observations of red giant stars reveal that planets or even other stars may influence the shape of a nebula’s cloud of dust and gas.
- Planetary Science
Rosetta data reveal an invisible ultraviolet aurora around comet 67P
Solar wind electrons smash water molecules in the comet’s coma to make the 67P/Churyumov-Gerasimenko’s version of the northern lights.
- Space
Neutrinos could reveal how fast radio bursts are launched
Highly magnetized stellar corpses called magnetars may be the source of two different cosmic enigmas: fast radio bursts and high-energy neutrinos.
- Space
How do you clean up clingy space dust? Zap it with an electron beam
An electron beam is the newest addition to a suite of technologies for cleaning sticky and damaging lunar dust off surfaces.
- Space
Phosphine gas found in Venus’ atmosphere may be ‘a possible sign of life’
Astronomers have detected a stinky, toxic gas in Venus’ clouds that could be a sign of life, or some strange unknown chemistry.
- Space
Dark matter clumps in galaxy clusters bend light surprisingly well
Cosmologists have found one more way to be confused by dark matter.
- Space
A weirdly warped planet-forming disk circles a distant trio of stars
The bizarre geometry of a disk of gas and dust around three stars in the constellation Orion could be formed by “disk tearing” or a newborn planet.
- Physics
Record-breaking gravitational waves reveal that midsize black holes do exist
The biggest merger of two black holes so far raises questions about how the pair of objects came to be.
- Planetary Science
Earth’s building blocks may have had far more water than previously thought
Space rocks and dust from the inner solar system could have delivered enough water to account for all the H2O in the planet’s mantle.
- Astronomy
Check out the first-ever map of the solar corona’s magnetic field
Solar physicists watched waves in the sun’s corona to map the whole corona’s magnetic field. Future observers could use the same technique to predict solar eruptions.
- Astronomy
In a first, astronomers spotted a space rock turning into a comet
Scientists have caught a space rock in the act of shifting from a Kuiper Belt object to a comet. That process won’t be complete until 2063.
