It's charging right through a nearby nebula. Plus Voyager 1's thrusters come back to life, water ice outside the Solar System, and the Universe will die sooner than we thought.
Why does this galaxy look this way? Plus new measurements of Jupiter, the coldest exoplanet ever found, and jets and eruptions from supermassive black holes.
A fantastic old image I'd never seen before, but is it real? Plus auroral electrojets and accreting black holes.
A high res composite from Solar Orbiter. Plus worrying ocean warming, a planet in a polar orbit, and our weird galactic neighbour.
No, it is not. Plus storms on Jupiter, a nearby supernova (eventually), and the discovery of a whole lot of hydrogen.
A mission which has revolutionised our understanding of the Milky Way.
JWST has delivered the goods yet again.
It's more likely than it sounds, plus auroras on Neptune, direct images of exoplanets, and a near miss with the Milky Way.
Supermassive back holes do more than pull things in, plus new research on meteorites, supernovae, and dark energy.
Where this newsletter's name comes from, plus a multitude of moons, droves of white dwarfs, and merging black holes.
Voyager instrument shutdowns, black hole discoveries, and water everywhere.
