"James Webb Space Telescope Uncovers Elusive Monster Galaxy Hidden in Dust"

The James Webb Space Telescope has rediscovered a mysterious dusty galaxy, known as AzTECC71, that had vanished from view after its initial detection by ground telescopes and the Hubble Space Telescope. These "Hubble dark galaxies" are difficult to observe at normal optical wavelengths due to the absorption of light by surrounding dust, making infrared detection crucial. The recent detection suggests that these dusty star-forming galaxies may be more common than previously thought and could provide insights into the early universe. The COSMOS-Web project, in which Webb is participating, aims to map one million galaxies and study the optical and infrared properties of heavily dust-obscured galaxies.
