CTOnews.com, Dec. 5 (Xinhua)-- NASA astronomers combined with COSMOS-Web, using the James Webb Space Telescope (JWST), re-photographed the AzTECC71 galaxy, which has become a faint but very strange galaxy.

Astronomers first spotted the AzTECC71 galaxy, a glowing spot, through ground-based telescopes; then the galaxy "disappeared" into the field of view of the Hubble Space Telescope, and now JWST has re-photographed the galaxy, and the current light is very faint. The AzTECC71 galaxy was formed by dusty stars, presumably born nearly 1 billion years after the Big Bang.

The artist's vision of AzTECC71 is that this ghostly object has two eyes and a wide open mouth, as if it were screaming into the abyss. Jed McKinney, a postdoctoral researcher at the University of Texas at Austin, said:

The AzTECC71 galaxy is really a monster. Although it looks like a small spot, it actually forms hundreds of new stars every year.

And even the most sensitive images from the James Webb Space Telescope are hard to see.

CTOnews.com Note: the COSMOS-Web project, co-led by Catelyn Caitlin Casey, an associate professor at the University of Texas at Austin, is the largest initial JWST research project that aims to map more than 1 million galaxies from a sky the size of three full moons.

The AzTECC71 galaxy, originally detected by a camera on the James Clark Maxwell Telescope in Hawaii, is a vague mass of dust emission.

The team estimates that the galaxy has a redshift of about 6, which means it formed about 900 million years after the Big Bang.
