Now, an international team led by Ignazio Ciufolini at the Chinese Academy of Sciences has carried out the most precise measurement yet of one of the theory's most subtle predictions: the dragging of spacetime caused by Earth's rotation. https://phys.org/news/2026-07-validate-einstein.html Astronomy Tue, 14 Jul 2026 07:30:01 EDT news703154341 China successfully recaptured the first stage of a rocket after a launch on Friday in a breakthrough for the country's space program, state media said. https://phys.org/news/2026-07-china-page-spacex-recaptures-stage.html Space Exploration Fri, 10 Jul 2026 13:30:01 EDT news702908159 Cities are often described as "heat islands," with media reports warning that some neighborhoods can be 20° F (7° C) hotter than others. But those temperatures are often based on satellite data rather than the conditions people actually experience, due to the dearth of near-surface urban observations. This data gap hinders understanding public health risks during heat waves, planning for energy demand, infrastructure resilience, and climate adaptation. https://phys.org/news/2026-07-block-ai-uncover-real-urban.html Environment Wed, 08 Jul 2026 17:10:01 EDT news702746045 Building material samples from the University of Delaware spent six months mounted outside the International Space Station, where the harsh conditions of low Earth orbit tested their limits. https://phys.org/news/2026-07-lab-moon-lunar-cement-alternative.html Space Exploration Wed, 08 Jul 2026 13:00:03 EDT news702724623 When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something else: low-frequency sound waves that traveled hundreds of miles and were captured by a dense network of earthquake and volcano-monitoring sensors on the ground. https://phys.org/news/2026-06-reconstruct-alaska-fireball-path-cameras.html Planetary Sciences Tue, 30 Jun 2026 16:00:10 EDT news702041402 An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration with Université Côte d'Azur/Observatoire de la Côte d'Azur and the University of Birmingham—has been published in Monthly Notices of the Royal Astronomical Society. https://phys.org/news/2026-06-super-puff-planets-lighter-candy.html Astronomy Wed, 24 Jun 2026 21:10:02 EDT news701508781 Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts of mass, including carbon, nitrogen and oxygen—the building blocks of life. In fact, the star may have produced elements on the periodic table all the way up to iron. As it exploded, it spewed these elements into deep space. Only a burnt-out core remained. https://phys.org/news/2026-06-alpha-magnetic-spectrometer-reveals-cosmic.html Astronomy Thu, 18 Jun 2026 16:00:05 EDT news701011442 Could Earth have seeded Jupiter's moon Europa with bacterial life, where it could have taken hold in Europa's ocean and perhaps evolved into something more? That's the hypothesis of a new paper in the International Journal of Astrobiology by Zaza Osmanov of the Free University of Tbilisi in Georgia. https://phys.org/news/2026-06-earth-life-jupiter-moon-europa.html Astrobiology Tue, 16 Jun 2026 09:20:07 EDT news700742290 Researchers combining two methods to reconstruct the rupture evolution of the July 2025 magnitude 8.8 Kamchatka earthquake found the rupture from the megathrust event extended about 500 kilometers (311 miles) from its epicenter. https://phys.org/news/2026-06-massive-kamchatka-earthquake-rupture-overlaps.html Earth Sciences Thu, 11 Jun 2026 11:20:09 EDT news700392001 Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego.

A new study led by the University of Zurich shows that loneliness isn't the only challenge posed by extreme environments. Constant physical proximity can also amplify conflict, mistrust and social withdrawal. The findings are published in the journal Proceedings of the National Academy of Sciences. https://phys.org/news/2026-05-months-antarctic-isolation-reveal-missions.html Social Sciences Mon, 25 May 2026 15:00:01 EDT news698921199 When a singer belts out a tune while a guitar player strums along, sound waves travel through the air, driving collective oscillations of the molecules within. Meanwhile, at the quantum level, something similar is going on. Atoms inside materials, everything from our bodies to metals and more, naturally jiggle around, creating tiny vibrational waves that ripple across the material. These vibrations are known as phonons: the quantum version of sound waves. https://phys.org/news/2026-05-tuning-quantum-acoustic-devices-sensors.html Optics & Photonics Mon, 25 May 2026 11:40:02 EDT news698925147 On May 21, ground controllers powered down NASA's AWE (Atmospheric Waves Experiment) instrument, bringing the data collection phase of the mission to a successful and scheduled end, surpassing its planned two-year mission. https://phys.org/news/2026-05-nasa-awe-instrument-mission-earth.html Planetary Sciences Thu, 21 May 2026 19:20:04 EDT news698599201 After the success of Artemis II, longer space journeys are expected, raising new health and nutritional challenges for astronauts.

This line is produced when a K-shell electron of an iron ion in the photosphere—the gas on the stellar surface—is ejected by an external process, and has been detected in X-ray spectra of solar and stellar flares. Yet the dominant mechanism behind this ionization process has remained an open question for many years. https://phys.org/news/2026-04-tandem-superflare-reveal-stellar-fe.html Astronomy Mon, 27 Apr 2026 05:00:01 EDT news696256870 It takes a moment for the eyes to adjust.
