A tiny pulsar with hardly any power is somehow blasting out gamma rays just as strong as the big ones, which totally breaks our physics models.
Nature Is Weird arxiv | Mar 17
We used to think long cosmic explosions only came from dying stars, but some are actually from black holes smashing together.
Paradigm Challenge arxiv | Mar 17
Those mysterious, insanely bright radio flashes from deep space? They might just be normal signals that got a massive boost from a star’s gravity.

The dark matter surrounding galaxies might be the exact 'glue' needed to prop open a wormhole you could actually travel through.
Cosmic Scale arxiv | Mar 16
We used to think giant galaxy car crashes killed off star-making, but it turns out that’s not what’s actually pulling the plug.
Paradigm Challenge arxiv | Mar 16
Black holes have this weird 'fuzz' that lets them remember everything that’s ever fallen in, long after the object is gone.
Nature Is Weird arxiv | Mar 16
Exploding stars aren't the reason galaxies stop making new stars—it's actually just because the whole galaxy is spinning too fast.
Paradigm Challenge arxiv | Mar 16
We finally found a 'dead' pair of stars that explains why thousands of star couples we expected to see in the sky are just missing.
Nature Is Weird arxiv | Mar 16
There’s a star that blew up 125 years ago that’s still glowing because the gas is basically taking its sweet time 'forgetting' the explosion.
Nature Is Weird arxiv | Mar 16
A new map of baby solar systems shows that almost every single one of them is warped or 'broken' instead of being a nice, flat disk.
Paradigm Challenge arxiv | Mar 16
Our solar system isn't flying through space like a comet; it's actually wrapped in a bubble shaped like a giant, split croissant.
Cosmic Scale arxiv | Mar 16
We found four alien worlds where it literally rains microscopic sand from high-altitude clouds.
Nature Is Weird arxiv | Mar 16
The math behind the Big Bang only really works if you assume some particles actually weigh less than zero.
Paradigm Challenge arxiv | Mar 16
A new AI can take a blurry photo from a basic telescope and figure out exactly what it would look like if a billion-dollar space telescope took it.
Practical Magic arxiv | Mar 13
We found a way to spot aliens without needing to know what they look like or what they’re made of—we just look for signs of complexity.
First Ever arxiv | Mar 13
Those weird "blueberries" all over Mars are all the exact same size because they literally can't grow any bigger than the dust in the air.
Nature Is Weird arxiv | Mar 13
A tiny neighbor galaxy is actually bending the Milky Way and leaving behind "ghost" trails of stars that we used to think were ancient relics.
Cosmic Scale arxiv | Mar 13
There’s a "zombie star" left over from an explosion in the year 1181 that’s still hauling ass through space at 10,000 miles per second.
Nature Is Weird arxiv | Mar 13
That bright star in the Southern Cross? It’s not one star. It’s actually a crazy family of seven stars all huddling together.
Nature Is Weird arxiv | Mar 13
The universe might not actually be speeding up—gravity might just be messing with our perspective and making it look that way.
Paradigm Challenge arxiv | Mar 13
Massive galaxy clusters are acting like giant magnifying glasses, making things from the early universe look 8 times bigger than they actually are.
Cosmic Scale arxiv | Mar 13
When a black hole’s jets turn off, they collapse like bubbles and basically camouflage the black hole so we can't find it.
Nature Is Weird arxiv | Mar 13
We just caught the "cosmic web" literally hand-feeding gas to tiny galaxies to spark massive star-making parties.
First Ever arxiv | Mar 13
If Mars was orbiting our neighbor star, its entire atmosphere would be gone in just 10 million years—poof.
Cosmic Scale arxiv | Mar 13
The Webb telescope found a massive "ring" galaxy from 12 billion years ago that likely formed after a brutal head-on cosmic car crash.
Cosmic Scale arxiv | Mar 13
