Astronomers have just found an absolute monster of a galaxy.
Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That’s 16.3 million light-years long, and constitutes the largest known structure of galactic origin.
The discovery highlights our poor understanding of these colossi, and what drives their incredible growth. But it could provide a pathway to better understanding, not just of giant radio galaxies, but the intergalactic medium that drifts in the yawning voids of space.
Previously, aircraft ✈️ had to fly at 1,500 to 5,000 feet for airborne radars to detect illegal activity in our seas 🌊. With SeaVue Multi-Role, pilots can fly as… See more.
In some parts of the world, the sea is lawless, fraught with piracy, smuggling and illegal fishing.
To help navies and coastal authorities combat illegal activity, Raytheon Intelligence & Space has developed the SeaVue family of airborne radars, which detect small maritime targets such as illegal fishing vessels, go-fast boats and stateless ships—ships not registered to a country or government, on the high seas. RI&S engineers have added a new, upgraded radar to the family called SeaVue Multi-Role.
The radar works with RI&S’ AN/DAS-4 Multi-spectral Targeting System, an electro-optical/infrared sensor, to image the targets, providing operators with enhanced actionable intelligence.
He’s absolutely right about birth rates and its implications for our species. OVER population is a disproven concept as far as our near and near-far future goes.

Fun fact: If you laid the International Space Station out end-to-end on a football field… it would be really tough to play a game. 🙃
The International Space Station is 356 feet (109 meters) long, just about one yard shy of an American football field—including the end zones. Go deep on more space station fun facts this #SBLVI: https://go.nasa.gov/3swABkE
Researchers from Stanford University developed a robotic gripper that uses gecko-inspired adhesives to pick up both delicate and robust objects. An earlier concept was tested aboard the International Space Station in May 2021 to see its potential.
