Hubble brings you a spooky cosmic face

This ghostly face, captured by the Hubble Space Telescope on June 19, is actually a collision of 2 galaxies of about equal size, 704 million light-years from Earth. Source: https://earthsky.org/todays-image/hubble-spooky-cosmic-face-image…

Putting the ‘bang’ in Big Bang

Physicists have pondered how the cold, uniform matter of the inflationary early universe became the ultrahot, complex mixture of matter, space and time that led to the universe we know. New work simulates a bridge between cosmic inflation and … everything else. Source: https://earthsky.org/space/big-bang-simulation-inflation-reheating-period…

Physicists Simulate Critical ‘Reheating’ Period That Kickstarted the Big Bang

An anonymous reader quotes a report from Phys.Org: Just before the Big Bang launched the universe onto its ever-expanding course, physicists believe, there was another, more explosive phase of the early universe at play: cosmic inflation, which lasted less than a trillionth of a second. During this period, matter — a cold, homogeneous goop — inflated exponentially quickly before processes of…

Cosmic Yeti from the dawn of the universe found lurking in dust

Astronomers accidentally discovered the footprints of a monster galaxy in the early universe that has never been seen before. Like a cosmic Yeti, the scientific community generally regarded these galaxies as folklore, given the lack of evidence of their existence, but astronomers in the United States and Australia managed to snap a picture of the beast for the first time.

Going against the flow around a supermassive black hole

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to study this cloud in more detail, they made an unexpected discovery that could explain why supermassive black holes grew so rapidly in the early Universe.

Cosmic web fuels stars and supermassive black holes

Astronomers probed the cosmic web, a large-scale structure composed of massive filaments of galaxies separated by giant voids. They found the filaments also contained significant amounts of gas, believed to help fuel the galaxies’ growth. Source: https://earthsky.org/space/cosmic-web-gas-reservoir-fuel-galaxies-growth…

Massive filaments fuel the growth of galaxies and supermassive black holes

An international group of scientists led by the RIKEN Cluster for Pioneering Research has used observations from the Multi Unit Spectroscopic Explorer (MUSE) at the ESO Very Large Telescope (VLT) in Chile and the Suprime-Cam at the Subaru telescope to make detailed observations of the filaments of gas connecting galaxies in a large, distant proto-cluster in the early universe.
