“The only secret to being in control is to have it in the beginning. Retaining control is still hard, but obtaining control is virtually impossible.” – Thomas Bangalter
Glimpse the past.
"The Torment of Saint Anthony" is a fascinating painting, often attributed to Michelangelo. If it is by Michelangelo, it is his earliest surviving work, having been produced in c. 1487–88 when he was a mere 12-13 years old.

After 9 years… and 3 BILLION miles… this is what we found 😳
For decades, Pluto was just a blurry dot in the sky.
But everything changed when NASA’s spacecraft finally arrived…
🚀 After an incredible journey across the Solar System,
we got our first close-up look at Pluto’s frozen world ❄️
🏔️ Massive ice mountains
🌌 Vast frozen plains
🌫️ A thin, mysterious atmosphere
This isn’t just a rock…
it’s a complex, active world at the edge of our Solar System.
✨ And the craziest part?
This data was sent back from billions of miles away…
taking hours just to reach Earth.
From a tiny dot… to a breathtaking world.
That’s the power of space exploration 🚀

Nicknamed "The Ghost Head Nebula," NGC 2080 is a star-forming region in a nearby galaxy, the Large Magellanic Cloud. The nebula's two bright "eyes" are blobs of hydrogen and oxygen that glow with the energy from new-born stars

A mysterious “superbubble” has hollowed out part of the N44 nebula
The cavity stretches about 250 light-years, and scientists still aren’t sure what caused it

One of the rarest event on Earth that we still can't explain, recorded over France.
For over a century, pilots swore they saw red light leap above storms. Scientists called it imagination — until 1989, when a camera caught one by accident.
They bloom 50 miles up, last a few milliseconds, and have been firing above thunderstorms for all of human history.
We just never looked high enough.

A Black Hole Can Be Dragged Through Spacetime
A Black Hole does not have to sit still.
Einstein’s equations allow a stranger possibility... a Black Hole that accelerates.
This is the C-metric, an exact solution of General Relativity describing an accelerating Black Hole.
The Black Hole accelerates because the geometry of Spacetime says it must.
The C-metric is one of those exact solutions that reminds us how wild General Relativity really is. Gravity is not just attraction, and Spacetime is not just a stage.
Sometimes the stage itself contains the force.

The 4 km-long stretch of river in the city of Yanagawa, Japan is ideal for a relaxing time on a donko boat.
And sometimes the boatmen can show off their skills in a somewhat theatrical way.
