JWST Cycle 4 focuses on earliest galaxies and stars

The Space Telescope Science Institute has announced the science objectives for the fourth cycle of the James Webb Space Telescope (JWST). This cycle includes 274 programs focusing on the earliest galaxies and stars, utilizing JWST's advanced infrared capabilities. New programs aim to study high-redshift galaxies, Population III stars, and the role of dark matter in galaxy formation. These observations will provide insights into the "Cosmic Dawn" and the "Epoch of Reionization," expanding our understanding of the early Universe. JWST's Cycle 4 will utilize 8,500 hours of observing time, significantly enhancing previous efforts to explore cosmic structures formed shortly after the Big Bang. This marks a major advancement in astronomical research.
