Our Milky Way galaxy isn't alone in this corner of space -- it's orbited by a few smaller dwarf galaxies, including the Large Magellanic Cloud. Inside that cloud is 30 Doradus (or the Tarantula Nebula), a "starburst" where stars are formed at a much higher rate than the surrounding area. And 30 Doradus has too many massive stars.

Sure, the restaurants are great, and you've probably got a decent sports team to barrack for. But the bright lights of a big city mean that at night you can rarely see more than a few stars in the sky, and these stunning timelapses of the galaxy overhead will make you realise the spectacular show you're missing every evening.
Oops! Andromeda, our closest galactic neighbour, sits a measly 2.5 million light years away from Earth. Like the Milky Way, it's a spiral galaxy packed with stars. Some of those stars orbit one another. That's all good - but scientists have come to the realisation that a particular light source, one assumed to be binary star system in Andromeda, may actually be something far stranger. Like a pair of orbiting supermassive black holes a thousand times further away.
The Earth, the Sun, Andromeda galaxy, they have all been around for as long as you can remember and as long as humanity has been around. So when a new light suddenly shows up in the distance, it's a weird occurrence. But a newly-detected explosion could be one of the weirdest - and it isn't the only one.
There are few downsides to new observations, but confusion might be one of them. New stellar images bring mysteries that will take more time and effort to understand. That's offset by how freaking detailed scientists can start producing these pictures, and of course, scientists like hearing that there's more work to do.
Overachievers, this mob.
Australian Scientists have had a busy week - but that hasn't stopped them from helping to solve the mystery of what causes exploding stars - used to measure the accelerating expansion of the Universe.
It's easy to feel small and insignificant in the grandiose scope of the universe, because we are. At the same time, as Carl Sagan once reminded us, we're made of the same "star stuff" as the cosmos. All too often, we forget how random, ridiculous, and resplendent it is to part of the stellar sorority of the universe. That's why art, specifically movies like Eliza McNitt's Fistful of Stars, is important -- it reacquaints us with humanity's small and stupid and somehow very special place in the cosmos.
The Sun and Proxima Centauri and most of the stars you've heard of orbit the centre of the Milky Way galaxy like children peacefully riding a carousel (with some weirdness caused by dark matter that we don't need to get into). Now, imagine if a few toddlers were sprinting and shrieking across the peaceful scene. Who sent these nightmares? In the case of stars, scientists think they could have come from another galaxy.
On Thursday, May 4, Hubble dropped a "cute" press release comparing a new image of a galaxy cluster to the Marvel movie Guardians of the Galaxy: Vol. 2. It was a timely yet mega-dad corny way to make the image of the galaxy cluster Abell 370 seem relevant. While there's literally no connection between the James Gunn movie and the galaxy cluster, located roughly four billion light years away, that didn't stop literally everyone from trying to make this A Thing.
It doesn't take much to amp up a room's ambiance -- at least not when you have the power of the cosmos at your disposal. Small but mighty, this Star Projector can bring the brilliance of a thousand stars straight to your living space (and it's on sale, too).
When it comes to cool space pictures, supernovae get all the credit. After all, who doesn't love a good star death? But new images from the Atacama Large Millimetre/submillimeter Array (ALMA) in Chile reveal a stunning star birth that gives those supernova snaps a run for their money. It looks just like a firework, and now I have that godforsaken song stuck in my head, because the internet has rotted my brain.
The marital feuds of strangers have long intrigued our degenerate species. It's a timeless topic that keeps several magazines afloat, even if literally none of the details are true. But what most don't know is that celebrities (and commoners) aren't the only ones who get divorced -- sometimes, actual stars do, too.
Don't get me wrong, black holes are cool, but they're also giant voids of terror: These gravitational abysses have been known to snack on stars in occurrences called Tidal Disruption Events (TDEs). It's always the same horror story -- an unsuspecting star wanders too close to a black hole, only to get ripped apart by the black hole's gravity. Isn't space pleasant?
