JWST finds ancient galaxy may actually be two galaxies merging

The James Webb Space Telescope has cast its eye on one of the oldest known galaxies, formed just 400 million years after the big bang, and it might be two galaxies merging

Researchers at SLAC National Accelerator Laboratory are nearly done with the LSST Camera, the world's largest digital camera ever built for astronomy. Roughly the size of a small car and weighing in at three tons, the camera features a five-foot wide front lens and a 3,200 megapixel sensor that will be cooled to -100??C to reduce noise. Once complete and in place atop the Vera C. Rubin Observatory's Simonyi Survey Telescope in Chile, the camera will survey the southern night sky for a decade, creating a trove of data that scientists will pore over to better understand some of the universe's biggest mysteries, including the nature of dark energy and dark matter.

Human hibernation is a real possibility - this is how it might work

Mounting evidence suggests that humans may have the biological hardware to benefit from some aspects of hibernation. Switching on these mechanisms could treat cardiac arrest, boost longevity and help people travel further into space
