Astronomers Identify the Earliest Strands of the Cosmic Web

Using NASA's James Webb Space Telescope, a team of scientists led by University of Arizona astronomers has discovered a threadlike arrangement of 10 galaxies that existed just 830 million years after the Big Bang.

Lined up like pearls on an invisible string, the 3-million-light-year-long structure is anchored by a luminous quasar – a galaxy with an active, supermassive black hole at its core.
