Back in 2002 I was working at Mammoth Mountain, and Adam Sandler came up to me and asked if I could get him change for $1

He was incredibly nice. No entourage. No attitude. Just a genuinely kind, low-key guy.

Sometimes the smallest interactions tell you the most about a person. 🇺🇸

The Hertzsprung-Russell Diagram is one of the most important maps in astronomy.

It doesn’t show where stars are in space. It shows where they are in life.

By plotting a star’s temperature against its brightness, astronomers can determine its size, age, and stage of evolution. From tiny white dwarfs to enormous red supergiants, nearly every star in the universe follows predictable paths across this diagram.

Our own Sun sits quietly on the Main Sequence, about halfway through its estimated 10-billion-year lifetime.

@amazing_physics We are not alone, there is 8.3 billion humanoids traveling on this planet at about 67,000 miles per hour (107,000 km/h) as it orbits the Sun.

More than 1.3 million Americans have given their lives in military service since our nation’s founding.

They came from every state, every generation, and every walk of life.

They shared one thing in common:

They gave their future so America could have one.

250 years later, we remember. 🇺🇸

Before dinosaurs, one tree changed the world.

Archaeopteris created Earth’s first forests, helping reshape the atmosphere, climate, and landscape nearly 385 million years ago. Every forest today traces its roots back to this ancient pioneer.

The first dinosaur fossil scientifically described was the lower thighbone of a Megalosaurus, discovered in an Oxfordshire, England shale mine in 1676. Originally mistaken for a giant human bone, it was officially classified as an extinct giant reptile by Oxford geologist William Buckland in 1824

The European Space Agency’s Euclid Space Telescope has unveiled the most detailed map of the Milky Way ever created, revealing over 60 million stars and 50 exoplanet systems.

@interstellargw @NASA Much better then when I was there in 2014 and tee-shirt sales took center stage.

@elonmusk Some days you run the simulation. Some days the simulation runs you.

Before Dracula…

The earliest vampire stories weren’t about capes, castles, or immortality.

They grew from folklore, fear, and the belief that the dead could still influence the living.

Every monster has an origin story.

A 2,000-year-old Greek machine could predict eclipses, track planets, and model the cosmos…

…nearly 2,000 years before the first mechanical computers.

George Washington died never knowing dinosaurs existed.

One of the most fascinating objects in the Solar System is Daphnis.

Although it’s only about 8 km (5 miles) across, Daphnis orbits inside the narrow Keeler Gap. As it travels, its gravity pulls on the countless ice particles that make up the ring.

The result is extraordinary: Daphnis creates towering waves along the edges of the gap. Some of these vertical ripples rise more than a kilometer (over half a mile) above and below the otherwise paper-thin ring plane, despite being caused by a moon smaller than many cities on Earth.

It’s a striking demonstration that even a tiny object’s gravity can sculpt enormous structures when acting on billions of particles over time. Thanks to the observations of the Cassini–Huygens, scientists were able to watch these waves evolve as Daphnis completed its orbit, turning Saturn’s rings into a natural laboratory for gravity and orbital dynamics.
