ALMA and James Webb Observe the Most Distant Galaxy Protocluster

An international collaboration led by Assistant Professor Takuya Hashimoto (University of Tsukuba, Japan) and Researcher Javier Álvarez-Márquez (Spanish Center for Astrobiology) has used the James Webb Space Telescope (JWST) and the Atacama Large Millimeter/submillimeter Array (ALMA) to observe the most distant galaxy protocluster to date, 13.14 billion light-years away. This profound observation has revealed this protocluster's dense 'metropolitan' core, indicating accelerated galaxy growth. Simulations suggest this region will merge into a singular, massive galaxy in the forthcoming tens of millions of years, offering insights into early galactic birth and evolution.

What is ALMA Astronomy News?

The Atacama Large Millimeter/submillimeter Array (ALMA) -the largest astronomical project in existence- is a single telescope of revolutionary design, composed of 66 high precision antennas located in northern Chile. ALMA is an international partnership of ESO (Europe), NSF (U.S) and NINS (Japan) together with NRC (Canada), MOST and ASIAA (Taiwan), and KASI (Republic of Korea), in cooperation with the Republic of Chile We love the Cosmos!
