NASA’s LRO images Falcon 9 crater on moon, learns new details

Between Aug. 11–12, NASA’s Lunar Reconnaissance Orbiter (LRO) captured a series of images of a new crater on the moon. The crater formed Aug. 5, when a SpaceX Falcon 9 upper stage impacted the surface following its Jan. 2025 launch of the Firefly Blue Ghost 1 mission.

A single asteroid impact may explain the appearance of Mars’ moon Deimos

Deimos, the smaller and outermost of Mars’ two moons, is roughly oval in shape and has a deep depression at its south pole. Unlike its heavily scarred sister moon, Phobos, Deimos is covered by a loose layer of dust and rubble—a so-called regolith layer—which gives it a smoother, dustier appearance. Although numerous space probes have provided increasingly detailed images of its surface over the past decades, the origins of the debris layer and the depression at the south pole remain unclear.

New photonic crystal method improves single-photon sources for quantum networks

Quantum communication promises many advantages over today’s standard technologies, including absolutely secure transmission of large amounts of data. However, it requires single photons—and generating them is very difficult. Researchers at the Technical University of Munich (TUM) and the Munich Center for Quantum Science and Technology (MCQST) have developed a new method that overcomes the problems of previous approaches.

Curved surfaces reshape active materials, localizing vibrations near defects

Many materials, both living and engineered, are powered from within. Scientists have thoroughly investigated how such ‘active’ materials operate, but so far, mostly in circumstances where the curvature of the environment does not play a role. In research published in Physical Review Letters this week, a team of physicists proposes a framework to describe how active materials operate in the presence of curvature. The framework explains striking biological observations and may lead to geometry as a design parameter for new materials.

‘Hidden stars’ suggest that distant galaxies are much more massive than they appear

Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more massive than initial measurements suggested. This discovery challenges current understanding about how the first galaxies formed. The results are published today in Nature Astronomy.

Sound-based traps reveal how fragile biomolecular droplets move, merge and change stiffness

Being able to measure something plays a vital role in our ability to understand many phenomena. But measuring can often affect what we are trying to measure. This is particularly the case when measuring substances that are very small, soft or fragile. In a recent study published in PRX Life, a research team led by the University of Osaka successfully used acoustic tweezers as a contactless method to investigate an important type of fragile material called biopolymer condensates.

Physicists entangle quantum memories across a record-breaking 420 km

Optical fibers are already the backbone of global communication systems. Recently, however, physicists have started to explore how their functionality could be boosted further by conveying information via entangled quantum particles—potentially enabling instantaneous exchanges of information across vast distances. Such a system could eventually be the basis of a future ‘quantum internet,’ offering a level of security and computing power beyond anything possible today.

NASA’s SkyFall Mars helicopters will feature a revolutionary antenna design

From 2021 to 2024, NASA’s Ingenuity helicopter became the first vehicle of its kind to explore the Martian atmosphere and surface. With that proof of concept complete, NASA is preparing to send a trio of helicopters to search for the most precious resource for future astronaut missions: water. Known as the SkyFall trio, these helicopters will detect frozen water within the top few meters of Martian regolith. To find possible water sources, each helicopter will use ground-penetrating radar with a flexible, fabric-based antenna extended beneath the spacecraft.
