Age of ancient galaxy discovered by Webb confirmed by ALMA | Digital Trends

Since the James Webb Space Telescope launched in December 2021, astronomers and the public have been excited to see how powerful this new tool is, and how it has been able to see some of the most distant galaxies ever observed. However, as cutting-edge science, some of these early results have been contentious as astronomers work to figure out how accurate the data is, due to issues like calibration of the instruments.

A group of researchers from Nagoya University and the National Astronomical Observatory of Japan looked at a galaxy named GHZ2 or GLASS-z12, which was first identified in the James Webb GLASS survey. To see if the galaxy really was as old as it appeared to be, the researchers used ALMA to perform a technique called spectroscopy, in which light coming from the target is broken down into different wavelengths.

“The first images of the James Webb Space Telescope revealed so many early galaxies, that we felt we had to test its results using the best observatory on Earth,” said lead author Tom Bakx of Nagoya University in a statement. “It was a very exciting time to be an observational astronomer, and we could track the status of the observations that will test the JWST results in real time.”
