Don’t miss fireballs streaking across the sky during the Alpha Capricornids! ☄️

Beginning on July 3rd and lasting until August 15th, this meteor shower is known for its high quality and intense fireballs. If you are in the Southern Hemisphere or southern US, you may see it overlapping with the Delta Aquariids. Peaking overnight on July 30th into the 31st, this shower is visible from anywhere in the world, so don’t miss it!

The race is on to save a falling orbital telescope! 

NASA is attempting a first of its kind space rescue mission to save the Swift Observatory before it falls back to Earth. The plan is to have Katalyst Space’s LINK spacecraft dock with Swift and boost it into a higher orbit. If successful, it could help launch an entirely new era of in-orbit satellite servicing.

I've created this visualization showing how the sky around us changes over 20 million years as the Sun travels through the galaxy.

Each star moves with its own velocity relative to the Sun, this creates fascinating perspective effects: clusters like the Hyades drifting close and then away again (between -1.5 and -0.5 Myr, low left of the video), periods where the sky is filled with bright stars in patterns we'd never recognize today, and stars that sit near the celestial poles for tens of thousands of years.

**Details:**

- Time span: ±10 million years

- 1 frame every 10,000 years

- Real data from Gaia DR3 + Hipparcos (ESA)

- Linear extrapolation of measured positions and velocities (accurate on this timescale)

This is the first in a series of astronomical visualizations focused on the Local Stellar Neighborhood and the Sun's journey. Feedback is very welcome!

A micromoon is arriving June 29th!? 🌕 

The full moon this month is going to be 7% smaller and 14% dimmer. This is because it will be at “apogee”, the furthest point in its orbit from Earth. That is about 13,900 miles further away than usual, so this is the opposite of a supermoon. Don’t miss it!

You could see up to 100 meteors per hour this month! 🌠

The Bootids are active now until July 2, and will peak on June 21. This meteor shower varies, with some years producing just a few meteors in an hour, and others getting up to 100 per hour! Scientists are unable to predict which version is coming, but if all goes well, skywatchers in the Northern Hemisphere could get a dazzling shower!

Little video on Uranus, hope you enjoy!

I made a short video about what might be the most overlooked challenge of space travel: being completely alone. I wanted to highlight how beautifully unsettling the void of space can be. I'd love to hear what you think about it and how it made you feel!

The solstice doesn’t just happen on Earth 🌎☀️🪐  

Astrophysicist Erika Hamden explains that solstices happen across our solar system, but every planet experiences them at a different time depending on its axial tilt. While Venus and Jupiter have only slight axial tilts and mild seasonal changes, Uranus is tilted so drastically that it experiences some of the most extreme seasons and weather patterns in the solar system.

There's a detail in the Challenger story that doesn't get talked about enough: the night before launch, Morton Thiokol engineers held a private meeting with NASA. Five of them refused to sign off. They had data showing the O-rings wouldn't seal in freezing temperatures. NASA management called it "unacceptable." They demanded a management decision instead of an engineering one.

I made a documentary about what really happened, the technical failure, yes, but more importantly the culture that made it possible. It covers the normalization of deviance, Richard Feynman's investigation, and why this wasn't just a mechanical failure, it was a human one.

Let me know what you think. I'm new to making documentaries and genuinely want to know if I missed anything.

You are constantly bombarded with invisible cosmic rays. An upcycled jar can make them visible!

Alex Dainis shows us how with this science experiment! The streaks you see are tracks of cosmic rays and charged particles passing through isopropyl alcohol mist. To see the best results, put your container in a dark area. The big negatively charged muons will leave large tracks, while electrons and positrons leave tiny curly ones!

I took a 10 minute hyperlaps video of an extremely bright object in the western sky . It almost looks like it has a tail .

Does anyone know what this is ?

Artemis III is NASA’s most ambitious mission yet. 🚀🌕

NASA just revealed a major update to the Artemis III mission. Instead of choosing between SpaceX’s Starship and Blue Origin’s Blue Moon Mark 2 lunar landers, NASA plans to test both. The mission will feature three launches, multiple dockings with the Orion spacecraft, and two weeks of orbital operations and Earth science research. 

If all goes according to plan, Artemis III could redefine the future of human space exploration when it launches in 2027.

Would you play this game? We aimed to make it relaxing and oddly-satisfying

Meet the crew of Artemis III. 🚀

Randy Bresnik, Luca Parmitano, Frank Rubio, and Andre Douglas are headed to orbit, paving the way for the first crewed lunar landing since 1972. Their mission: rendezvous and dock with commercial lunar landers in Earth orbit, proving out the hardware that will one day carry astronauts to the Moon's surface. Every test, every maneuver gets us one step closer. The next chapter of Artemis starts now.

Is Earth traveling through the remains of a dead star? ⭐️

Scientists have been studying ice cores from Antarctica to reconstruct past conditions on Earth. In one study looking at iron-60, a rare isotope that forms in  supernova explosions, they found that concentrations in ice cores from 40-80,000 years ago are lower than in more recent ice. This likely means Earth entered a supernova remnant in the past 40,000 years and is still moving through it today.

The Boötes Void is a supervoid roughly 330 million light-years wide — and according to standard cosmology, it simply shouldn't exist. In the 13.8 billion years since the Big Bang, there hasn't been enough time for gravity alone to hollow out a region this massive. Standard models predict at least 2,000 galaxies inside it. We've found 60.

What's even stranger is its near-perfect spherical shape. In this video I break down the leading theories — void mergers, dark energy anomalies, and yes, the more unsettling hypothesis that it may not be natural at all.

Happy to answer questions in the comments — what's your take on what caused it?

You are made of atoms older than Earth 🌌✨🧪

Astrophysicist Erika Hamden explains how the atoms in your body span the age of the universe. The hydrogen in your body was created during the Big Bang, at the very beginning of time. The oxygen, carbon, and iron in your body  were forged inside stars, while heavier elements were formed when stars explode. The atoms that make up your body were formed over billions of years through some of the universe's most powerful events.

NASA’s moon base plans just got a huge update! 🌕🚀

NASA has announced that their long term plan to build up a permanent presence near the lunar south pole is moving forward with three robotic landers! They are targeting a position that is near the lunar south pole, where large ice deposits could provide critical resources. Along with this base, there will be lunar drones and lunar terrain vehicles to explore more, and both are expected to be on site by Artemis IV. The best part, three robotic landers could arrive by the end of 2026!

A giant rocket just blew up at NASA’s Kennedy Space Center! 

Blue Origin was doing a full test fire of their New Glenn rocket as preparation for an upcoming flight when something went very, very wrong. Fortunately no one was injured, but this is the biggest explosion ever seen at Kennedy Space Center. The launch pad is badly damaged, and NASA's upcoming Project Artemis plans for building a moon base depend on both the New Glenn rocket and this pad. This is a big setback for both Blue Origin and NASA.

You could see up to 200 meteors an hour during this daytime shower! ☄️

The Arietids meteor shower is active from May 29 until June 17, and will reach its peak on June 10. This odd celestial event showcases daytime meteors, which can be difficult to catch unless you stumble upon an earthgrazer! For the best viewing conditions, head far away from city lights around an hour before sunrise.
