For years, the fate of the powerful space telescope was uncertain.
It went way over budget, and for 25 years, troubling conversations accompanied its ongoing development. Several times, it seemed like it would be canceled, and in 2011, Congress came close to ending the program. So when it was finally launched on Dec. 25, 2021, there was a collective sigh of relief in the astronomy community.
As observations began, astronomers, cosmologists, exoplanet scientists and astrophysicists around the world anticipated the telescope's findings. The telescope didn't disappoint. JWST found surprisingly bright, well-developed galaxies only several hundred million years after the Big Bang, clashing with our scientific understanding at the time.
Since its initial observations, JWST has continued to stun us with its early universe findings. One of JWST's first and most important surveys was JADES, the JWST Advanced Deep Extragalactic Survey. JADES is responsible for many of the telescope's surprising observations of the young universe.
The shock at JWST's findings has subsided somewhat, and now astronomers are examining these findings more deeply to see what they can learn. In new research in The Astrophysical Journal based on JADES, researchers found a "galaxy overdensity candidate" that could help explain the universe's reionization. Reionization is when the first stars and galaxies formed and illuminated their surroundings, reionizing hydrogen atoms in the primordial universe.
Prior to this, the universe was opaque and dark. After this, photons were free to travel and the cosmos lit up. The research is titled "JADES: A Prominent Galaxy Overdensity Candidate within the First 500 Myr," and the lead author is Zihao Wu.
