Using a gravitational lens — a massive cluster of galaxies bending light — the James Webb Space Telescope detected two red dots in a distant galaxy. These are intermediate-mass black holes, located not in the center but on the outskirts. The discovery suggests such invisible objects might be widespr

In a new study presented in the MEOW survey, astronomers used the MIRI infrared camera on the James Webb Space Telescope to search for dust-obscured active galactic nuclei from an era when the Universe was less than a billion years old. Analyzing the emission from hot dust allowed them to identify 1
