Amaterasu Particle That Broke Physics Has Finally Been Explained
A mysterious, extremely energetic particle, known as the Amaterasu particle, was detected coming from a distant region of space, and scientists have proposed explanations for its origin, potentially tracing it back to a starburst galaxy like Messier 82 ##
## Questions to inspire discussion.
Understanding Ultra-High Energy Cosmic Rays.
🔬 Q: What makes the Amaterasu particle exceptionally powerful? A: The Amaterasu particle detected in Utah in 2021 carries energy 40 million times higher than anything produced on Earth, equivalent to a baseball traveling at 100 km/h compressed into a single subatomic particle, making it one of the most energetic particles ever detected.
Solving the Origin Mystery.
🎯 Q: Where did scientists determine the Amaterasu particle actually originated? A: A 2026 study by Max Planck Institute scientists using approximate Bayesian computation and 3D magnetic field simulations traced the particle’s origin to a starburst galaxy like Messier 82, located 12 million light-years away, rather than the initially suspected local void with only six known galaxies.
Humans Age Faster at 2 Sharp Peaks, Study Finds
Getting older might seem like a slow, gradual process – but research suggests that this is not always the case.
In fact, if you wake up one morning, look in the mirror, and wonder if your aging somehow accelerated, you might not be imagining things.
According to a 2024 study into the molecular changes associated with aging, humans experience two abrupt lurches forward, one at the average age of 44 and the other at around age 60.

Elon Musk reveals his most ambitious (and detailed) plan for Mars: 1,000 spacecraft, 20 years of launches, and a self-sustaining city of one million inhabitants on Mars by 2050
At the entrance to Starbase in south Texas, a glowing sign now welcomes visitors with the words “Gateway to Mars.” The display sits in front of SpaceX facilities where giant Starship rockets are being assembled with one bold purpose in mind: Elon Musk wants to build a self-sustaining city on Mars.
In recent years he has begun to put numbers on that dream. Musk has repeatedly said that building the first sustainable city on Mars would require around 1,000 Starship rockets and roughly 20 years of launch campaigns, moving up to 100,000 people per favorable Earth-Mars alignment and eventually reaching about one million settlers plus millions of tons of cargo.
It sounds like science fiction with a project plan. Yet the language he uses, “sustainable city,” is very familiar to climate and energy experts here on Earth. So what does sustainability really mean on a frozen, air-thin world and how does that huge effort interact with the environmental crisis on our own planet?
