This was a crucial time known as the Epoch of Reionization. Ryan Endsley of the University of Texas at Austin led an investigation into galaxies that existed 500 to 850 million years after the big bang. "With JADES, we want to answer a lot of questions, like: How did the earliest galaxies assemble themselves? How fast did they form stars? Why do some galaxies stop forming stars?" said Marcia Rieke of the University of Arizona in Tucson, co-lead of the JADES program. The team also has identified galaxies sparkling with a multitude of young, hot stars. While the data is still coming in, JADES already has discovered hundreds of galaxies that existed when the universe was less than 600 million years old. ![]() ![]() One of the largest programs in Webb's first year of science is the JWST Advanced Deep Extragalactic Survey, or JADES, which will devote about 32 days of telescope time to uncover and characterize faint, distant galaxies. Webb Telescope reveals early universe crackled with bursts of star formationĪmong the most fundamental questions in astronomy is: How did the first stars and galaxies form? NASA's James Webb Space Telescope is already providing new insights into this question. ![]()
