The Dutch shipbuilder Royal Huisman used an engineering process developed by the European Space Agency (ESA) for space missions in the design of the superyacht Sea Eagle II — expected to become the largest aluminum sailing yacht in the world upon delivery to its owner this Spring.
Engineering design used by the European Space Agency was used to create the largest aluminum superyacht.
Astronomers have spotted a cosmic blast that dwarfs all others.
A gargantuan explosion tore through the heart of a distant galaxy cluster, releasing about five times more energy than the previous record holder, a new study reports.
“In some ways, this blast is similar to how the eruption of Mt. St. Helens in 1980 ripped off the top of the mountain,” study lead author Simona Giacintucci, of the Naval Research Laboratory in Washington, D.C., said in a statement. “A key difference is that you could fit 15 Milky Way galaxies in a row into the crater this eruption punched into the cluster’s hot gas.”
Freeman Dyson, renowned scientist and scholar, has died at 96, according to his daughter Mia.
The British-born scientist and professor emeritus spent much of his career as a physics professor at the Institute for Advanced Study in Princeton, according to his biography on the institute’s website. He was among 29 scientists who supported the Obama administration’s 2015 nuclear deal with Iran. In 1967, he also acted as a military adviser regarding the use of tactical nuclear weapons in the Vietnam War, and in 1984 he wrote a book on the dangers of nuclear warfare.
A futurist and space-enthusiast, Dyson had several scientific concepts named after him, including the “Dyson Tree,” a genetically engineered plant that would be able to survive in a comet and grow in space. One of his ideas, the Dyson Sphere, was featured in an episode of the sci-fi series Star Trek.

Earth has acquired a second “mini-moon” about the size of a car, according to astronomers who spotted the object circling our planet.
The mass—roughly 1.9−3.5 meters (6−11 feet) in diameter—was observed by researchers Kacper Wierzchos and Teddy Pruyne at the NASA-funded Catalina Sky Survey in Arizona on the night of February 15.
“BIG NEWS. Earth has a new temporarily captured object/Possible mini-moon called 2020 CD3,” likely to be a C-type asteroid, Wierzchos tweeted on Wednesday.
In 2019, NASA’s James Webb Space Telescope celebrated the full mechanical and electronic assembly of the world’s largest, most powerful space science observatory ever built. Meaning that Webb’s two halves have been physically put together and its wiring harnesses and electronic interfaces have been fully connected.
Following assembly, the Webb team moved on to successfully send deployment and tensioning commands to all five layers of its sunshield, which is designed to unfold in space, and protect the observatory’s mirrors and scientific instruments from light and heat, primarily from the Sun.
“This has been an amazing journey to get here. The James Webb Space Telescope is now one complete assembly, and known to be the most powerful space telescope ever created by humankind,” said Mark Voyton, Webb Observatory Integration and Testing, and OTIS Manager at NASA’s Goddard Space Flight Center, Greenbelt, Maryland.
It’s been with us for three years, astronomers say. Sadly, it’ll probably be gone by spring.
Astronomers discovered a ‘minimoon’ that’s been orbiting Earth for about three years, and may soon leave our planet’s orbit.
CAPE CANAVERAL, Fla. (AP) — A communication satellite almost out of fuel has gotten a new life after the first space docking of its kind.
Why is there something rather than nothing? We’re finally making enough antimatter to extract an answer – and it might reveal the dark side of the universe too.
Planetary imaging is a fun and rewarding hobby that allows beginners and advanced amateur astronomers to delve into astronomical imaging without much of the expense and complexity of deep space astrophotography. There are also quite a few opportunities for planetary imagers to contribute to some significant scientific research. However, it is important to first understand what equipment is needed to successfully capture images of the solar system. In addition, some basic understanding of our atmosphere and optics are required, which will be addressed in this write-up.

Astronomers have announced that Earth has a new mini-moon, a small asteroid apparently captured into Earth orbit 3 years ago. It’s been designated 2020 CD3.
