The true color of the Sun from space.

For a few seconds, the sky looked like a meteor shower.

But these were not meteors.

On March 25, 2021, a SpaceX Falcon 9 second stage reentered Earth’s atmosphere over the Pacific Northwest and began breaking apart.

As the rocket stage disintegrated, pieces of the spacecraft became intensely bright while heating during atmospheric reentry, creating dozens of glowing trails across the night sky.

People across the region watched what looked like a spectacular shower of shooting stars moving across the sky.

The strange part?

It was not a natural cosmic event.

It was human made space hardware coming back to Earth.

The rocket stage came from a Falcon 9 launched on March 4, 2021, carrying Starlink satellites into orbit. Its planned deorbit did not occur as expected, leaving the upper stage to eventually reenter the atmosphere.

For a few unforgettable seconds, a piece of a SpaceX rocket made the night sky look like another world.

Pulsars are among the fastest spinning objects in the universe.

These three neutron stars show just how extreme their rotation can become.

First, the Crab Pulsar, PSR B0531+21.

It spins about 30 times every second and sits at the heart of the Crab Nebula, roughly 6,500 light years away. It was born in the supernova observed on Earth in 1054 and remains one of the youngest and most energetic pulsars known.

Then there is PSR J1012+5307.

This millisecond pulsar rotates about 190 times per second, completing one rotation in only about 5.3 milliseconds. It is part of a binary system with a very low mass white dwarf companion, and its extraordinarily precise timing has made the system useful for testing theories of gravity.

And then comes PSR J1748−2446ad.

This neutron star spins about 716 times every second, completing a full rotation in just 1.396 milliseconds. It is located in Terzan 5, a dense stellar system in the direction of Sagittarius, roughly 18,000 light years away. It remains the fastest known pulsar.

That means this tiny collapsed star is rotating hundreds of times every second while containing more mass than the Sun inside an object only a few tens of kilometers across.

Pulsars are not just fast.

They are some of the most extreme natural laboratories in the universe.

“Those aren’t mountains. They’re waves.”

At first, the horizon of Miller’s Planet looks like a mountain range.

Then you realize something is terribly wrong.

Those towering structures are oceans, rising nearly 4,000 feet into the sky. That is around 1.2 kilometers of water towering above the planet’s surface.

The reason is Gargantua, the supermassive black hole at the center of this terrifying world.

Miller’s Planet orbits incredibly close to Gargantua, placing it in an environment where the black hole’s immense gravity produces extreme tidal forces.

Those forces distort the planet and make it rock back and forth. As the planet moves, its oceans are driven into enormous waves, creating the towering walls of water seen in Interstellar.

And that is what makes this scene so unsettling.

You are not looking at mountains in the distance.

You are looking at an ocean coming toward you.

Interstellar brought one of the most extreme consequences of gravitational tides to the screen, turning an invisible force of nature into something you can actually see.

That’s what the extreme gravity of a black hole can do.
