☆ Scientists used a galaxy cluster that warps space-time as a giant magnifying glass to find 2 distant galaxies

A team of astronomers used a cluster of galaxies like a magnifying glass to discover two never-before-seen distant galaxies. Pandora's Cluster warps the fabric of space-time, creating a visual effect that magnifies light behind it. The two newly uncovered galaxies are two of the most distant galaxies ever detected. AdvertisementScientists used a galaxy cluster that warps the fabric of space-time like a magnifying glass, helping them discover two of the most distant galaxies ever observed. These two distant galaxies are also special because of their unique shape.

☆ Scientists updated the human genome to make it more inclusive

CNN —Scientists have pieced together a new draft of the human genome that better captures humanity’s genetic diversity. The scientists involved say it will improve our ability to diagnose disease, discover new drugs and understand the genetic variants that lead to ill health or a particular physical trait. The pangenome, a digital amalgamation of sequences that can be used to compare, construct and study other human genome sequences, is still a draft. The first draft of the human genome was released in 2001 and was only fully completed in 2022. The new pangenome reference is an amalgamation of different genomes from 47 people with ancestry from around the world.
☆ Galaxies spotted by Webb telescope rewrite understanding of early universe

These galaxies, one of which appears to have a mass rivaling our Milky Way but 30 times more densely packed, seem to differ in fundamental ways from those populating the universe today. "The leading theory is that an ocean of dark matter filled the early universe after the Big Bang," Labbe said. "This dark matter - we don't know what it is actually is - started out really smooth, with only the tiniest of ripples. These ripples grew over time due to gravity and eventually the dark matter started to collect in concentrated clumps, dragging hydrogen gas along for the ride. "Their explosion set off the chain of events that formed subsequent generations of stars," Labbe said.
