James Webb Space Telescope Uncovers Massive “Cosmic Vine” in Early Universe

Published on November 21, 2023
Current Context: The "Cosmic Vine" in a study published Nov. 8 to the preprint database arXiv — swoops through space in a bow shape, estimated to stretch more than 13 million light-years long and about 650,000 light-years wide. (For comparison, our Milky Way galaxy is about 100,000 light-years wide.)
James Webb Space Telescope Uncovers Massive “Cosmic Vine” in Early Universe
  • Pandora’s Cluster (Abell 2744): The JWST uncovered new details in a region of space known as Pandora’s Cluster. This cluster is a conglomeration of already massive clusters of galaxies coming together to form a mega cluster.
  • Massive Galaxies in Early Universe: The JWST spotted six massive galaxies that emerged not long after the Big Bang. These galaxies formed at a speed that contradicts our current understanding of the universe. One of these galaxies is believed to have around 100 billion stars, making it around the size of the Milky Way.
  • Active Galactic Nuclei (AGN): A survey using the JWST revealed that AGN—supermassive black holes that are rapidly increasing in size—are rarer than many astronomers had assumed previously.
  • These discoveries are helping astronomers gain a deeper understanding of the universe and its evolution.

Question:

Q.1 What is Pandora’s Cluster?
a. A single galaxy
b. A conglomeration of galaxy clusters
c. A black hole
d. A nebula
