Astronomers at Uppsala University have calculated that the Sun contains 55 percent more silver than previous estimates suggested. For years, scientists studying the composition of the solar system faced an enduring puzzle. While the Sun, planets, and primitive meteorites all condensed from the same primordial cloud of gas and dust approximately 4.6 billion years ago, … Read more

New computational modeling reveals that liquid water from Europa’s global subsurface ocean is far less likely to reach the moon’s upper ice layer than previously assumed. Published in Nature Astronomy, the research demonstrates that the icy shell acts as a rigid barrier, complicating future space exploration missions targeting Jupiter’s moon. The search for extraterrestrial life … Read more

Researchers have documented a previously unknown orca feeding and socialization strategy in the Mexican Pacific and Gulf of California, where killer whales were filmed coordinating to ram dead sharp-tail sunfish with such explosive force that the heavy carcasses shattered into thousands of tiny fragments. Cooperative Ramming Caught on Video in Mexican Waters The rare hunting … Read more

The U.S. The July 2026 decision clears the Eärendil-1 prototype for communications testing despite sharp protests from astronomers. A Los Angeles-based startup called Reflect Orbital has cleared a major regulatory hurdle in its quest to commercialize nighttime sunshine. The U.S. Federal Communications Commission approved a license for the company’s experimental Eärendil-1 satellite, authorizing the spacecraft’s … Read more

Anglian Water confirmed that no fines have been issued following the implementation of a hosepipe ban across parts of Norfolk and Suffolk, which began on July 11 during the region’s third summer heatwave. Meanwhile, Uisce Éireann introduced hosepipe bans across Ireland, carrying statutory penalties of up to €5,000 for non-compliance. Norfolk and Suffolk Hosepipe Restrictions … Read more

Orcas in the Gulf of California have been documented engaging in a previously unknown collaborative feeding strategy, teaming up to ram dead sharp-tail sunfish with such intensity that the carcasses explode into small fragments. Researchers detailed the observations in a paper published in the journal arstechnica.com. Orcas Exhibit Novel Ram-to-Fragment Behavior in Gulf of California … Read more

NASA astronaut Chris Williams and two Roscosmos cosmonauts are preparing to return to Earth following a 241-day mission aboard the International Space Station, with undocking scheduled aboard the Soyuz MS-28 spacecraft for Sunday, July 26, after completing thousands of orbits and millions of miles of travel. Mission Timeline and Return Details for Soyuz MS-28 The … Read more

Scottish Power is set to invest £1.5 billion to repower the Whitelee Windfarm in Scotland, replacing 215 existing turbines with 124 larger models. The project, expected to run from 2030 to 2035, will nearly double the site’s capacity to approximately 1 gigawatt, enough to power roughly 650,000 homes. Repowering the UK’s Largest Onshore Wind Farm … Read more

Mission Objectives and Speed The spacecraft would strike its target at speeds exceeding 9 kilometers per second (about 26 times the speed of sound), surpassing NASA’s 2022 Double Asteroid Redirection Test (DART) mission, which impacted a target at 6.1 km/s. The goal is to directly alter the asteroid’s orbit relative to Earth, potentially breaking its … Read more

NASA reports a 48% visible Moon on July 21 As of Tuesday, July 21, NASA’s Daily Moon Guide tracker reports that the Moon is in its First Quarter phase, with 48% of its surface visible. This follows the July 20 commemoration of International Moon Day, an event held annually to celebrate the role the Moon … Read more

Professor Ginestra Bianconi Proposes Gravity from Entropy A new theoretical framework, Gravity from Entropy (GfE), proposes that gravity emerges from informational mismatches in spacetime. Published July 16, 2026, in Physical Review D, the research by Queen Mary University of London mathematician Professor Ginestra Bianconi suggests this model could resolve the long-standing conflict between the second … Read more

Researchers have identified the object that caused the mass extinction 66 million years ago as a rare CO carbonaceous chondrite. Using precise nickel isotope analysis, the team determined the asteroid was an unusual, pristine projectile that likely triggered global catastrophe through fine debris rather than sulfur, as reported in Science Advances. Identifying the Chicxulub Impactor … Read more
