The sun just fired a bullet of plasma.

Speed: up to 3,000+ km/s
= 6.7 MILLION mph

Fastest ones reach Earth in 14-17 HOURS.

We can't stop it.
But we can see it coming.

That's space weather.

Beauty of the Nights!

NO SHIELD. NO MERCY.

Mars has no magnetic field.

When a solar storm hits, the entire planet glows with aurora.

Add a dust storm:

water lifted 80km high
sunlight splits H2O
solar wind sweeps hydrogen into space
This is how Mars lost its oceans.

Earth has a shield. Mars didn't

Google just put AI in orbit. 🚀

Yesterday, SpaceX launched Google's Suncatcher prototype from California — a refrigerator-sized satellite carrying 4 TPUs in a sun-synchronous orbit with 24/7 sunlight.

For the next year it will test if AI chips can survive 100Gs, cosmic rays etc

WHEN A STAR DIES, IT OUTSHINES AN ENTIRE GALAXY
This is a supernova - the most violent explosion in the universe. 1 real NASA photo and a cinematic photo of the spectacular space phenomena
A single star, many times more massive than our Sun.

Could ONE solar storm shut down the internet? 😳

1859: Telegraphs caught fire.
2026: Everything runs on the grid.

A superstorm today = huge currents through power lines → transformers overheat → lights out.

📷 A Massive "Kelvin Wave" is Heading for the California Coast
Have you heard of a Kelvin wave?
Unlike the crashing waves you see at the beach, this is a slow-moving, planetary-scale surge of warm water spanning thousands of miles across the Pacific Ocean!

LOOKS CALM. IT ISN'T. 🌀

This galaxy's core is spinning THE WRONG WAY.

Meet NGC 4698. 55M light-years away.
Its arms don't touch the center.
Its core rotates 90° to the whole disk.
Scientists think it's a scar from a past merger or outside gas that crashed

This black hole shouldn't exist. Gaia BH3 = 33 Suns packed into pure darkness. 1,900 light-years away. Not feeding. Not glowing. Completely dormant.
Scientists found it because a nearby star was orbiting NOTHING.
No light. No X-rays. Just gravity revealing a sleeping giant. 🕳️

WHY DOES THE SKY GLOW GREEN? 💚 It's not magic. It's a planet-sized neon sign. You are literally watching SUNLIGHT become EARTH LIGHT.

The Harvest Moon
The September 2026 full moon peaked on Saturday, September 26, 2026, at 12:49 p.m

📷 WHY DOES THE SKY GLOW GREEN? Sometimes purple?
It's happening 60 miles above ALL of us right now.
📷 The Sun fires wind at 1 MILLION mph at Earth
📷 Earth's magnetic shield catches it
📷 Oxygen atoms get hit = GREEN glow
📷 Nitrogen atoms get hit = PURPLE glow

Meteor shower coming up

[Spaceweathertracker @SpaceSkiesEarth]

Imagine a magnet so powerful it could wipe the data from every credit card on Earth... from halfway to the Moon.
📷Meet the Magnetar. It's a type of neutron star with a magnetic field a trillion times stronger than Earth's.

📷 TRULY HISTORIC BEHEMOTH IN THE PACIFIC 📷
This is Hurricane Polo — and it just became the 2nd STRONGEST hurricane EVER recorded in the Eastern Pacific.
180 MPH sustained winds. Category 5. And still strengthening.
Scientists are calling the physics obscene.
