New research with GW230814 upholds Hawking black hole area law
Saturday, 15 November 2025 08:46
Researchers from Purple Mountain Observatory have conducted an observational test of the black hole area law. Using the gravitational-wave event GW230814, which features a high signal-to-noise ratio, the team closely examined the event horizons of merging black holes. The black hole area law, first proposed by Stephen Hawking in 1971, predicts that the total event horizon area after a merger wil Blue Origin planning next New Glenn flight for early next year

A solar prominence hovers over the Sun

The Sun is always mesmerising to watch, but Solar Orbiter captured a special treat on camera: a dark ‘prominence’ sticking out from the side of the Sun.
The dark-looking material is dense plasma (charged gas) trapped by the Sun's complex magnetic field. It looks dark because it is cooler than its surroundings, being around 10 000 °C compared to the surrounding million-degree plasma.
When viewed against the background of space, the hovering plasma is referred to as a prominence. When viewed against the Sun's surface, it is called a filament. (In this image you can see examples of both.)
Solar prominences and filaments extend for tens of thousands of kilometres, several times the diameter of Earth. They can last days or even months. This video

Members of Maryland’s congressional delegation added their voices to concerns about the closure of offices and labs at the Goddard Space Flight Center.
China's Shenzhou-20 astronauts return to Earth after delay
Friday, 14 November 2025 09:57
Three Chinese astronauts returned to Earth on Friday, state TV footage showed, after a delay caused by their spacecraft being struck by debris in orbit.
The Tiangong space station, the crown jewel of China's space programme, is crewed by teams of three astronauts who are exchanged every six months.
The return of the Shenzhou-20 spacecraft and crew were planned for November 5, after the S Blue Origin launches NASA Mars mission and nails booster landing
Friday, 14 November 2025 09:57
Jeff Bezos's Blue Origin successfully launched its New Glenn rocket on Thursday with NASA twin spacecraft destined for Mars aboard, and in a breakthrough nailed the landing of its booster.
The launch was stalled for days over weather both on Earth and in space, but it was worth the wait: in the rocket's second-ever flight, Blue Origin managed to recover the booster for reuse.

Friday, 14 November 2025 09:57
Sierra Space announced completion of a series of critical pre-flight tests for its Dream Chaser spaceplane at NASA's Kennedy Space Center, marking progress toward the vehicle's first uncrewed mission.
Dream Chaser underwent Electromagnetic Interference and Electromagnetic Compatibility testing in NASA's Space Systems Processing Facility to confirm the spacecraft's operation in expected ele Atlas 5 rocket launches U.S. communications satellite
Friday, 14 November 2025 09:57
Following a handful of troubling valve issues that pushed a launch back for a week, an Atlas 5 rocket lifted off from Cape Canaveral Space Force Station in Florida at 10:04 p.m. EST on Thursday night, carrying a communications satellite for Viasat.
The 6-ton Viasat 3 satellite will be deployed from the Atlas rocket about 3 1/2 hours after launch, and eventually reach geostationary orbit Our Solar System Is Moving Faster Than Expected
Friday, 14 November 2025 09:57
How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by astrophysicist Lukas Bohme at Bielefeld University has now found new answers, ones that challenge the established standard model of cosmology. The study's findings have just been published in the journal Europe Strives to Counter Russian and Chinese Satellite Menace
Friday, 14 November 2025 09:57
Europe finds itself in the midst of a new space race, one defined less by exploration and more by the imperative to safeguard critical orbital infrastructure from the mounting threats of Russian and Chinese satellite activities. While the world has watched the rollout of advanced technology and military escalation in space, recent years have shown just how vulnerable the continent remains - and
