“This is a real monster.”
Ice Galaxy
NASA’s James Webb Space Telescope has encountered a mysterious but familiar “ghost”.
The dusty and faint galaxy was previously undetectable by the Hubble Space Telescope, but has been revealed by observations from other ground-based telescopes.
So the reappearance of AzTECC71, a very distant star-forming galaxy that dates back nearly 1 billion years after the Big Bang, has scientists excited. astronomers, giving them a fascinating glimpse into the ancient structures of the universe.
The information suggests that many birth defects may be more common – three to ten times, to be exact – as previously thought.
If that is true, scientists may have to rethink how we understand the beginning of the universe, making it a much “dustier” place than expected.
“This is a real monster,” said University of Texas postdoctoral researcher Jed McKinney, author of a recent paper published The Astrophysical Journalin what new media. “Although it looks like a small bubble, it actually creates hundreds of new stars every year.”
“And the fact that even such an object can barely be seen in the most sensitive images from our new telescope really excites me,” he added. “It may tell us that there is a whole population of galaxies that is hidden from us.”

The research is part of JWST’s COSMOS-Web project, which is looking to map up to 1 million galaxies to gain a better understanding of first period of the universe.
While analyzing the data, astronomers tried to hunt down AzTECC71, which was too faint to be seen by NASA’s Hubble telescope, but it did. revealed as a plume of dust by the James Clerk Maxwell Telescope in Hawaii.
Thanks to James Webb’s more sensitive infrared instruments, however, they found a regular, but faint, galaxy in its place.
“Until now, the only way we’ve been able to see galaxies in the early universe is from a special perspective with Hubble,” McKinney said in a statement. “This means that our understanding of the history of galaxy evolution is biased because we are looking at galaxies that are less illuminated, less dusty.”
The James Webb could “pierce the thick veil of dust,” according to McKinney, which could change the way we understand the beginning of the universe — and perhaps unlock countless more. galaxy like AzTECC71.
