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

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

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

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

Researchers led by the Department of Astronomy at Tsinghua University have identified a galaxy labeled CR3, which shows evidence of containing stars from the earliest phase of the universe. The team used data from the James Webb Space Telescope, the Very Large Telescope, and the Subaru Telescope to examine CR3. It is situated almost 11.5 billion years in the past, at the epoch known as cosmic no

A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping - the act of measurement itself. In a study published 14 Nov in Physical Review Letters, scientists demonstrate that the energy cost of reading a quantum clock far outweighs the cost of running it, with implications for the design of future quantum technologies. Clocks, whether pend

Chandrayaan-3 was developed to demonstrate the capability for a controlled lunar landing, enable rover mobility on the Moon, and facilitate in-situ research. The mission includes a lander module, propulsion module, and rover. The satellite launched aboard LVM3 from SDSC SHAR, Sriharikota, on July 14, 2023. Following its lunar touchdown on August 23, 2023, the propulsion module maintained l

Since comet 3I/ATLAS, the third known interstellar object, was discovered on 1 July 2025, astronomers worldwide have worked to predict its trajectory. ESA has now improved the comet's predicted location by a factor of 10, thanks to the innovative use of observation data from our ExoMars Trace Gas Orbiter (TGO) spacecraft orbiting Mars. By being able to use Mars-based data for an unusual ob
