The most interesting things that happened in the last 12 hours, on Earth and off it.
Meanwhile, near Sagittarius A*…
Water and dust are forming and surviving within a few light-years of the four-million-solar-mass black hole at the center of the Milky Way. JWST found the evolved star IRS 3 still seeding its surroundings with fresh material despite radiation that should strip such chemistry apart. The region astronomers assumed was sterile turns out to be quietly manufacturing the ingredients of planets.
Meanwhile, in Earth's atmosphere…
Perfect data and a perfect model would still only get you 129 days of weather forecast. Beyond that, the atmosphere's own chaos erases any trace of today's conditions, setting a hard ceiling no computer can climb. It is a rare case of science measuring precisely how much of the future is permanently off-limits.
Someone built a page that lets you scroll through every possible state of a Rubik's Cube — all 43,252,003,274,489,856,000 of them. You will never reach the end, and that is the point: the interface turns an abstract number into a physical sensation of scrolling forever.
Meanwhile, over Hainan Island…
A Long March 7A carrying the ChinaSat 4B communications satellite exploded shortly after clearing the pad at Wenchang. The rocket is one of China's workhorses for geostationary payloads, and failures of this class are rare enough that each one reshapes a national launch schedule.
The upper stage of a Falcon 9 slammed into the Moon in an uncontrolled collision — nobody aimed it, and nobody could stop it. With spent hardware still drifting through cislunar space, the arithmetic of building a permanent lunar base now has to include the odds of being hit by our own leftovers.
Mars may have kept liquid water on its surface long after the three-billion-year freeze date astronomers have used for decades. Pushing that deadline forward widens the window in which the planet could have been habitable — and changes where a rover should be digging.
Meanwhile, at Sardis in western Turkey…
A monumental marble statue of a young man was found buried facedown at Sardis — not hidden, not toppled in anger, but laid flat to be used as paving. Roughly 2,500 years of artistry ended up as something to walk on, which says a great deal about how quickly one civilization's masterpiece becomes another's building material.
Meanwhile, in the La Brea Tar Pits…
Saber-toothed cat vertebrae pulled from the La Brea Tar Pits carry an unusual load of deformities, including signs of spinal nerve tumors. The pattern points to inbreeding in a shrinking population — a portrait of the last generations of a predator on its way out, written in bone.
Meanwhile, on the Finnish-Swedish border…
Trains are running between Finland and Sweden again for the first time in decades, and the reconnection quietly completes a rail chain from Portugal all the way to Lapland. It is believed to be the longest continuous train journey available in Europe.
An executive order limits several childhood vaccinations and calls for the combined measles, mumps and rubella shot to be split into separate injections. The American Academy of Pediatrics called the MMR recommendation dangerous, noting that separating the doses means more needles and longer gaps in protection.
