In Short: A new paper suggests the first starbursts in the universe might have been larger than previously thought, challenging current understanding.

A new study, pre-printed on arXiv by Tae Bong Jeon from the Cosmic Frontier Center at the University of Texas at Austin, explores the potential size of the universe's first starbursts and whether they could be detected by the James Webb Space Telescope.

Some galaxies near the end of the Epoch of Reionization exhibit features that seem to indicate these starbursts occurred, but much later than expected, prompting questions about their true nature and timing.
