The Champagne Cluster is a rare and beautiful example of two galaxy clusters smashing together. Its festive name comes from both its New Year’s Eve discovery and its bubbly appearance in space. Images reveal superheated gas and galaxies spread across a massive collision zone. Astronomers believe this system could help explain how dark matter responds when giant structures collide.

Scientists have uncovered why big predators like sharks spend so much time in the ocean’s twilight zone. The answer lies with mid-sized fish such as the bigscale pomfret, which live deep during the day and rise at night to feed, linking deep and surface food webs. Using satellite tags, researchers tracked these hard-to-study fish for the first time. Their movements shift with water clarity, potentially altering entire ocean food chains.

Researchers found that U.S. metal mines already contain large amounts of critical minerals that are mostly going unused. Recovering even a small fraction of these byproducts could sharply reduce dependence on imports for materials essential to clean energy and advanced technology. In many cases, the value of these recovered minerals could exceed the value of the mines’ primary products. The findings point to a surprisingly simple way to boost domestic supply without opening new mines.

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster—and fluctuate over the Martian year. These microsecond shifts could play a big role in future Mars navigation, communications, and even a solar-system-wide internet. It’s a small time gap with big consequences for space exploration.

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed using the James Webb Space Telescope, which was able to isolate the blast from its faint host galaxy. Surprisingly, the explosion closely resembles supernovae linked to gamma-ray bursts in the modern universe.
