NASA and India’s space agency ISRO are collaborating on a suite of science investigations aboard Axiom Mission 4, a private astronaut mission to the International Space Station set to launch no earlier than June 10 aboard a SpaceX Dragon spacecraft. The mission will carry experiments probing human biology, plant growth, and technology use in microgravity. […]

Sharks have long been regarded as silent predators, but a new study shows that small rig sharks (Mustelus lenticulatus) can make clicking sounds when handled. Evolutionary biologist Carolin Nieder discovered the noise by accident during shark hearing tests. In lab trials, juvenile rigs emitted rapid “click…click” noises when restrained. The results, published in Royal Society […]

Nuclear physicists have detected the radioactive disintegration of a rare isotope of astatine for the first time. This shows that the heaviest element found in nature may be modified a lot, maybe even destroyed, in a way that scientists didn’t predict. That oddball radioactive decay with 85 protons and 103 neutrons is almost (but not […]

Hubble’s latest view reveals a jewel-like cloudscape of gas and dust in the Large Magellanic Cloud (LMC), a dwarf galaxy about 160,000 light-years from Earth. This Milky Way companion is our galaxy’s largest satellite, and its active stellar nurseries glow in intricate pastel filaments. The wispy tendrils in the image have been likened to brightly […]

Astronomers have found a way to see through the turbulent atmosphere of a distant planet that experienced heat and gale-force winds — conditions that are thought to be similar to those on an early version of Earth that was also cold and blanketed by clouds. They accomplished it with the help of the NASA James Webb Space […]

On June 4, SpaceX sent another batch of Starlink satellites to orbit from Vandenberg Space Force Base in California. This is one piece of SpaceX’s strategy to continue getting satellites into orbit fast in 2025. Starlink 11-22 lifted off at 7:40 p.m. EDT (4:40 p.m. PDT) when the Falcon 9 rocket roared into space on the way […]

Astronomers have seen the most energetic cosmic explosions yet, a new class of eruptions termed “extreme nuclear transients” (ENTs). These rare events occur when stars at least three times more massive than our Sun are shredded by supermassive black holes. While such cataclysmic events have been known for years, recent flares detected in galactic centres revealed a […]

NASA’s Interstellar Mapping and Acceleration Probe (IMAP) has started to get ready for the launch. It was removed from its shipping container on Thursday, May 29, after being transferred from the airlock into the high bay at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida. Its objective is to study […]

Rocket Lab successfully launched a Gen-3 Earth-observing satellite for Virginia-based BlackSky on June 2, marking another step in private-sector space imaging. The mission, named Full Stream Ahead, lifted off aboard an Electron rocket from the company’s New Zealand launch complex at 7:57 p.m. EDT (11:57 a.m. NZST on June 3). The satellite is headed for […]

NASA’s RASSOR (Regolith Advanced Surface Systems Operations Robot) was recently tested on simulated lunar soil at Kennedy Space Center’s Granular Mechanics and Regolith Operations LabThe excavator is built to dig and haul Moon-like regolith, preparing technology for sustained lunar missions. On May 27, NASA mechanical engineer Ben Burdess observed RASSOR’s counterrotating bucket drums churn through […]

Life in the solar system may not entirely end when the sun begins its dramatic transformation into a red giant star. Instead, a brief window of potential habitability may open on Europa, Jupiter’s icy moon, according to new research. Scientists now suggest that as the sun expands and its habitable zone shifts outward, Europa could […]

In September 2023, an unusual seismic signal reverberated around the globe every 90 seconds for nine consecutive days and was then repeated a month later. Scientists were initially unable to identify the source. Almost a year later, two scientific studies proposed that the cause of these seismic anomalies were two mega tsunamis which were triggered […]

Mars used to be a wetter world. Scientists have long pointed to evidence like dried-up riverbeds and ancient lake basins. For that much water to exist, Mars would have needed a thicker atmosphere — one that could hold in heat and pressure. But today, Mars is cold, dry, and barely has any air. For the […]
