Interesting things hiding in plain sight. Technology, science, business, history & everything in between.

🌌 Scientists may have just discovered an entirely new kind of cosmic object.

A BLACK HOLE STAR.

Not a black hole.

Not a star.

A gigantic cocoon of gas wrapped around a rapidly feeding black hole — shining like a star and dating back to just 660 million years after the Big Bang.

JWST keeps finding things that apparently weren’t on the menu. 🔭

🕳️ Astronomers may have just discovered a completely new kind of object.

A “black hole star.”

It’s a supermassive black hole buried inside an enormous cocoon of gas — so dense that the whole thing can shine almost like a star.

And it already existed just 660 million years after the Big Bang.

Apparently black holes weren’t weird enough.

🐬 Dolphins have apparently invented takeaway containers.

Researchers have filmed bottlenose dolphins chasing fish into empty sea shells, carrying the shells to the surface, draining the water…

…and tipping the fish straight into their mouths.

Even better, a calf was seen learning the trick from its mother.

Dolphins are getting worryingly good at this.

🐁 Britain has a venomous mammal.

It’s not a snake.
It’s not some exotic import.
It’s the water shrew.

This tiny native predator uses venomous saliva to subdue insects, amphibians and small fish.

Yes. Britain has venomous shrews.

And they’re ridiculously cute.

🌍 Something deep inside Earth changed direction — and scientists still don't know why.

2,200 km beneath us, molten iron flows around Earth's core, helping generate our magnetic field.

But around 2010, a huge region beneath the Pacific suddenly reversed direction.

Scientists have now tracked the change from space.

What caused it?

Still a mystery.

🌳 This was hidden beneath the Amazon rainforest.

Using LiDAR to see through the dense canopy, researchers have uncovered hundreds of previously unknown ancient earthworks — roads, settlements and huge geometric structures.

And that may only be the beginning.

Researchers estimate 24,000–30,000 could still be hidden beneath the forest. 👀

🏺 Nobody had touched what was at the bottom of this well for more than 2,000 years.

Archaeologists excavating the ancient Etruscan city of Kainua in Italy have uncovered a sacred well containing bronze objects deliberately left as offerings.

They appear to have been placed there as part of rituals connected to the goddess Uni — and remained undisturbed since antiquity.

Then archaeologists reached the bottom.

🧊 Ötzi died more than 5,300 years ago.

Scientists found something remarkable living alongside the famous Iceman.

Cold-loving yeasts associated with his body survived — and researchers were able to grow living colonies from samples.

After 5,300 years.

☀️ This is the sharpest visible-light image of the Sun ever taken.

Those flower-like structures are solar plasma — and the smallest details visible are roughly the size of a city.

Scientists have even spotted swirling instabilities in them that had long been predicted, but never seen this clearly.

🚀 Humans just added another crater to the Moon.

On Wednesday, a discarded Falcon 9 upper stage was expected to slam into the lunar surface after spending around 18 months travelling through the Earth–Moon system.

Scientists tracked it closely enough to predict the impact point near the Einstein and Bell craters.

NASA planned to watch the collision with telescopes and spacecraft — turning a piece of space junk into an unexpected scientific experiment.

Sometimes even the rubbish is useful. 🌕
