7,000 Galaxy Clusters, Hiding in Plain Sight

A five year survey by the South Pole Telescope has produced a catalogue of more than seven thousand galaxy clusters, some dating back nearly eight billion years, giving astronomers their most detailed map yet of the universe's largest structures. Hidden inside the data is something even the researchers did not expect, a discovery that is quietly reshaping how we think star formation unfolded across the history of the universe. from Universe Today https://ift.tt/FZnJScW via IFTTT

Detecting Atomic Weapons in Space

The Outer Space Treaty from 1967 prohibits weapons in space. But a satellite launched by Russia has generated suspicion. Despite claims that it's a normal satellite, some things about it suggest otherwise. New research proposes a way to detect atomic weapons in space, helping enforce the treaty. from Universe Today https://ift.tt/KRUw0oB via IFTTT

The JWST and the Mystery of Massive Quenched Galaxies in the Early Universe

With its ability to observe the red-shifted light from early galaxies, the JWST has revealed some surprises. Many massive galaxies in the early Universe had ceased star formation and were already quenched hundreds of millions of years sooner than thought. By examining their morphology, new research shows that mergers that were previously hidden from view are responsible. from Universe Today https://ift.tt/bDsKjR5 via IFTTT

Another Success for Hayabusa 2 as it Completes a Flyby of Asteroid Torifune

JAXA's Hayabusa 2 has completed its flyby of asteroid Torifune. The spacecraft came within about 800 meters of the asteroid's surface. Though the spacecraft is travelling very rapidly, making navigation challenging, it was still able to capture clear images of the asteroid's boulder-strewn surface. Based on ground-based observations, scientists suspected that Torifune was a contact binary asteroid, and these images confirm it. from Universe Today https://ift.tt/s0BT8GJ via IFTTT

The Euclid Space Telescope Has Found 31 New Ancient Quasars, Including the Most Ancient One Ever Found

Euclid is only 1.5 years into its Euclid Wide Survey and has found 31 new quasars from the Universe's first 800 million years. Though the Survey isn't specifically aimed at finding ancient quasars, it's proving to be remarkably effective at it. This large sample of quasars will help with the study of ancient galaxies and supermassive black holes. from Universe Today https://ift.tt/V5UBM0K via IFTTT
