Open-source clock framework aims to synchronize deep space missions
Saturday, 15 November 2025 08:46
Vartis Space Corp. has introduced the Vartis Space Clock, an open-source framework that enables independent synchronization of zero-time reference points for space operations without relying on Earth-based signals.
The company describes the clock framework as a step toward establishing a temporal infrastructure that supports satellites, lunar operations, and missions throughout the Solar S Haystack scientists study recent geospace storms and light shows

The northern lights, or aurora borealis, one of nature's most spectacular visual shows, can be elusive. Conventional wisdom says that to see them, we need to travel to northern Canada or Alaska. However, in the past two years, New Englanders have been seeing these colorful atmospheric displays on a few occasions - including this week - from the comfort of their backyards, as auroras have been vi Chang'e-6 lunar mission finds impact-created hematite and maghemite in SPA Basin samples
Saturday, 15 November 2025 08:46
Researchers from the Institute of Geochemistry, Chinese Academy of Sciences (IGCAS), and Shandong University have identified, for the first time, crystalline hematite and maghemite produced by a major impact event in lunar soil returned from the South Pole-Aitken (SPA) Basin by China's Chang'e-6 mission. These findings, published in Science Advances, offer direct evidence from lunar samples indi 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

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.
