Space is big, as Douglas Adams so succinctly put it. But how big? And what does the Universe look like when you see it at those scales. The structure of the large-scale cosmos is amazing — beyond galaxies, beyond clusters of galaxies, we're talking super-mega-ludicrous clusters. Clusters of clusters. Madness. In the last 20 years two advances have given us a glimpse of the Universe at these largest scales: surveys of galaxies that map out the cosmos in fine detail, and stupendously complex simulations on powerful supercomputers. At the heart of it all, responsible for the intriguing filaments and walls and voids — the cosmic sponge itself — we find an old, mysterious, dark friend.

Astronomers have spotted a void, a cavity, a big hole in the intergalactic stuff in a cluster of galaxies far away. And this thing is big. Very big — fifteen Milky Way Galaxies across. The void was created by a stupendously energetic jet erupting from a Super Massive Black Hole in the centre of one of the galaxies, and when they did the maths, the researchers realised they were looking at the aftermath of the biggest explosion since ... well, since the Big Bang itself!

Super Snow Moon. Super Worm Moon. Super Pink Moon. Super Flower Moon. We're tripping over the Super Moons this year, there's so many lying around all over the place. Why so many? And what is a Super Moon anyway? Does it matter? What even is a month? Does that matter either? And — most importantly — is the moon bigger near the horizon? Emily's here with all the answers.

SpaceX do amazing work on the spaceflight and technology stuff, but they could use a bit of work on their consultation and collaboration skills. Starlink, their satellite constellation program designed to bring broadband to the globe via tens of thousands of tiny communications satellites, will increase the number of shiny objects orbiting the Earth by a factor of ten. That's a big issue for astornomers, and they're pretty upset about it. But it's bigger than that. This is about who owns the sky, whether our view of the universe deserves protecting, and gets to have a voice in decisions like this. 

Typically, black holes are portrayed as monstrous, pitch-black space beasts gobbling up stars and planets — but Emily is here to salvage their reputation. See, some supermassive black holes are special: called quasars, they emit stupendous jets of energy that stretch across intergalactic space, sending shockwaves into neighbouring galaxies that can kickstart new star formation.
