The death of a binary star can be a spectacularly violent thing.
This picture shows the binary system R Aquarii, a red giant throwing off its outer envelope, which is being greedily cannibalised by its companion, a much smaller, denser white dwarf.
The dramatic moment you’re looking at unfolded just 650 light-years from Earth – practically right next door in astronomical terms, which is why astronomers have a keen interest in the event.

An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships.
It’s a goal that sounds so fantastic, you’d be forgiven for dismissing it as science fiction. But it’s no joke, and the project’s chief engineer says millions of dollars’ worth of work is moving along without any major snags.
Starshot’s founders and collaborators include the late Stephen Hawking, Harvard University astronomer Avi Loeb, and Russian-American billionaire Yuri Milner. The concept is based on more than 80 scientific studies about interstellar travel.

Space agencies are working hard to get humans back to the surface of the Moon. But it’s not exactly the most inviting place.
Astronauts during the Apollo 11 mission in 1969 may not have had any health incidents while they were gleefully bouncing around on the lunar surface, as a NASA mission report from the time points out. But they knew that lunar dust wasn’t their friend — it could irritate their lungs, cause their Moon buggies to overheat — it even started degrading their spacesuits.
