Astronomers still aren't sure about the source of fast radio bursts, but they appear to come from newly formed neutron stars, with powerful magnetic fields that interact with their surroundings. Researchers were surprised to find a burst that came from the last place you'd expect to see a young neutron star: an ancient elliptical galaxy, which ran out of most of its star-forming gas and dust long ago. So, maybe fast radio bursts have something to do with older stars?

Astronomers have analyzed the atmosphere of WASP-127b and discovered that its windspeeds reach 33,000 km/h. This is the fastest jetstream that's ever been measured on a planet—over 10 times faster than Neptune's winds, which are the fastest in the Solar System. The winds go 6 times faster than the planet itself is rotating. One clue is the extremely low density of WASP-127b; it's bigger than Jupiter, but a fraction of its mass. It's also tidally locked to its star.
