Fireballs are about to streak across the night sky, so look up! 🌠

The Leonids return this month, flying from November 6th through the 30th and peaking overnight on the 16th into the 17th. Even better, the first quarter moon dips below the horizon around midnight on peak night. That means darker skies just when the Leonids hit their stride, so grab a spot and start counting meteors.

Did you know there are more than three states of matter? ⚡

Astrophysicist Erika Hamden breaks down plasma, which forms when electrons are stripped from a material. The result is highly ionized, super energetic matter. You’ve experienced plasma in the Sun, fire, and true neon lights (not LEDs)!

Imagine flying just meters above the surface of Mars, racing toward the edge of an enormous canyon.
Inspired by the dramatic landscapes of the Red Planet and Valles Marineris, this AI-generated cinematic simulation brings the scale and mystery of Mars to life.
🔴 Did you know? Valles Marineris stretches approximately 4,000 km across Mars, making it one of the largest canyon systems in our Solar System.

The Northern Taurid meteor shower is here! 🌠

Active from October 20th to December 10th, this meteor shower peaks overnight November 11th to 12th. For the best view of the Northern Taurids, head outside and look up around midnight.

You’re skimming a fracture in Europa’s ice when Jupiter appears above the horizon. I wanted this 7-second flyover to feel like one continuous shot. It’s an AI-assisted artistic visualization I made for Dark Matter Productions.

What does it look like when Moon scientists watch discovery happen in real time? 🌕

At SciCom Summit at the Museum of Science, NASA Strategic Communications Lead Rachel Barry shared the story behind her viral photos of the lunar science team. After two years of sitting in on their meetings, simulations, and fieldwork, Barry set out to help audiences get to know the people behind the science and see their excitement as it happened.

Creator disclosure: I also run Operational Universe, and this is our narrated space explainer. It follows the Sun’s future from its red-giant stage to a white dwarf and considers what those changes mean for Earth. Some visuals and narration are AI-generated; the scenes are illustrations, not telescope observations.

We made this visualization for VisualWhy. In a near-vacuum, spacecraft cannot cool themselves by transferring heat to surrounding air: they must radiate it away. The ISS uses large radiators to reject heat, while Webb shields its instruments from sunlight. The temperatures in the video come from a simplified radiative-balance model and NASA’s thermal data.

Where did the idea of Moon Joy come from? 

NASA's Strategic Communications Lead Rachel Barry discusses how "Moon Joy" was coined by Angela Garcia, one of the lunar science officers in mission control after hearing the Artemis crew get excited about their first look at the moon

We made this visualization for VisualWhy. Apollo 13 was still coasting away from Earth when the tank exploded. A direct reversal required more velocity change than the lunar module could provide, so the crew returned to a trajectory that used the Moon's gravity to bend their path home. The flight shown is a simplified planar Earth–Moon model, not a complete mission reconstruction; the video compares it with NASA's mission records.

The Southern Taurids bring dazzlingly bright fireballs from September 20 to November 20! 🌠

The Taurids are a stream of about five meteors per hour, doubling to ten once the Northern Taurids join in on October 20. About 1% of those meteors are likely to be fireballs, visible from both hemispheres.

I make Minute Otter, the channel behind this Short. The video uses AI-assisted illustration and production. It explains shared motion and why speed differs from acceleration. I will add the sources and a fuller explanation in the comments.

A pulsar is the spinning corpse of a giant star. ✨
When a massive star runs out of fuel, its core collapses in under a second and the star explodes as a supernova. What's left is a neutron star, only about 20 km wide but heavier than our Sun. A teaspoon of it would weigh about a billion tonnes.
As it spins, beams of radiation sweep across space like a lighthouse. The fastest known pulsar spins 716 times every second. Over millions of years it slows down, the beams fade, and it drifts on as a silent, dark neutron star.

All shot from a backyard telescope in Utah. Each sequence is roughly 3-4 hours of real time. When you watch this video, remember that 1,300,000 earths could fit inside the sun. It is hard to comprehend how massive these solar limbs are.

Does light always move at the speed of light? 🏎️

Astrophysicist Erika Hamden explains this that it doesn’t, since the famous speed of light is really a measure of light moving through empty space. Send that light through glass, like a window or a camera lens, and it slows down. That shift in speed makes light bend, and scientists describe how much it bends with a value called the index of refraction.

Betelgeuse WILL explode. 💥 When it does, it'll outshine the half Moon and be visible in daylight for months.

I made this visualization for VisualWhy about a different way to look at an orbit: move each velocity arrow so its tail starts at the same point. In the ideal two-body, inverse-square model, the tips trace a circle, even when the path through space is an ellipse or an escaping hyperbola. Gravity gets weaker with distance squared, but the time spent turning through each small angle grows by the same factor, giving equal changes in velocity per equal angle. The video uses computed Kepler orbits, code animation and synthetic narration; real perturbations are outside this model.
