The Day Mars Died – 60th Anniversary of Mariner 4 – YouTube Watch On On Episode 169 of This Week In Space, Rod Pyle and Tariq Malik are joined by Rob Manning, JPL’s Chief Engineer Emeritus, to look back at the Mariner 4 Mars mission 60 years later. Six decades ago this week, the Mariner 4 probe sped past Mars, …

In a recent study, divers near Kumejima Island in Japan discovered an unusual sea creature with a distinctive panda-like appearance. These creatures, part of the Clavelina genus, were first thought to be part of an aquarium display, only to surprise researchers by being a completely new species. The discovery has drawn attention from marine biologists and citizen scientists alike, as …

Astronomers have spotted the earliest known signs of rocky planet formation around a young, sun-like star for the first time. The discovery offers an unprecedented glimpse into what may have happened at the dawn of our own solar system. What did the researchers see? Using NASA’s James Webb Space Telescope and the European Southern Observatory’s ALMA array in Chile, researchers …

The world of Bousso’s new theorem still departs from our universe in notable ways. For mathematical convenience, he assumed that there’s an unlimited variety of particles—an unrealistic assumption that makes some physicists wonder whether this third layer matches reality (with its 17 or so known particles) any better than the second layer does. “We don’t have an infinite number of …

IN A NUTSHELL 🌞 Solar storms are causing SpaceX’s Starlink satellites to reenter Earth’s atmosphere sooner than planned. 🚀 The increased atmospheric drag from geomagnetic storms shortens the satellites’ lifespan by 10 to 12 days. ⚠️ A higher risk of satellite collisions emerges due to unpredictable drifts caused by solar activity. 🛰️ Managing a crowded orbit is crucial as more …

A team of scientists has developed a powerful new way to detect subtle magnetic signals in common metals like copper, gold, and aluminum—using nothing more than light and a clever technique. Their research, recently published in the prestigious journal Nature Communications, could pave the way for advances in everything from smartphones to quantum computing. The Longstanding Puzzle: Why Can’t We …

New clues from ancient seas are reshaping what we know about mass extinction and the future of our oceans. In a recent breakthrough, scientists have confirmed for the first time that a sudden, sharp drop in ocean pH—driven by a massive release of carbon dioxide—played a central role in wiping out entire ecosystems over 200 million years ago. A team …

Scientists have made an exciting discovery that could transform your daily breakfast meal. According to Phys.org, for the first time ever, researchers from McGill University have altered oat DNA with great success. By editing oat DNA, scientists have the potential to produce oats that are not only richer in fiber but also more resilient to rising global temperatures.  Published in …
