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.

Anyone who has had to share a room—or worse, a bed—with a loud snorer knows the effect unchecked snoring can have on sleep, sanity and emotional stability. An entire industry of products, technologies and treatments claims to cure or prevent loud snoring, with varying degrees of success.

Close to a phase transition, very different materials can follow the same mathematical rules. The concept of universality, which groups seemingly distinct systems based on their common properties, was developed to describe this phenomenon.

Superconductors are materials in which electrical current flows with a resistance of zero, typically below specific temperatures. In conventional superconductors, this state of matter emerges when two electrons bind together at low temperatures, forming so-called Cooper pairs.

So far, most of the minerals found on Mars tell a story of lava poured out by ancient volcanoes, followed by long stretches in which water trickled through and slowly reshaped the rock. However, some rocks scattered across the Martian surface seem to hint at a different geological history—carrying the same material that forms rubies and sapphires.

Readers of a certain age will remember a golden era of asteroid films, capped by two with very different endings. “Deep Impact” drove home the devastating consequences of letting a large piece of rock hit our planet, whereas “Armageddon,” though arguably the kitschier of the two films, was an uplifting story about technical ingenuity and sacrifice.

Quantum sensors, devices that collect measurements by exploiting quantum-mechanical phenomena, could potentially detect extremely weak magnetic, gravitational and electromagnetic signals with greater sensitivity than classical sensors. Some quantum sensors leverage entanglement, a phenomenon that prompts distant particles to become so strongly linked that the physical state of one particle dictates the state of the others.

Our home galaxy, the Milky Way, grew to its current size in part by consuming smaller galaxies. Now, new data from NASA’s Hubble Space Telescope show definitive evidence of a dwarf galaxy merging with the young Milky Way in the earliest phases of its evolution. This finding extends our knowledge of our galaxy’s history 1.8 billion years farther back in time than before. The results are published in the journal Nature Astronomy.

From helping doctors detect cancer to guiding self-driving cars through traffic, many modern imaging systems rely on near-infrared light, producing a crisp picture when visible light would scatter and yield a blurry picture. But near-infrared systems struggle when light passes through materials like deep tissue or dense fog, succumbing to the same scattering effect in which photons deviate from their path. Existing near-infrared imaging systems also rely on specialized detectors made from expensive materials, limiting their affordability and widespread use.

What is heat, and what is useful work if a machine consists only of an atom and light particles? In modern quantum technologies, this kind of question connects thermodynamics with quantum physics. Researchers at the University of Basel, Switzerland, have developed a theoretical approach that can reconcile both theories.
