| Description |
Through the combined power of NASA’s James Webb Space Telescope and gravity creating "natural telescopes" in space, astronomers hope to answer two science questions that are fundamental to understanding the origins and evolution of the universe: - How did the first galaxies in the universe form, and did they make the universe transparent to light? - How did later galaxies produce and disperse into the universe the heavier elements that are the building blocks of stars, planets, and even humans? These questions will be addressed in some of the first observations made by the Webb telescope, slated to launch in March 2021. These observations will be part of the Director's Discretionary-Early Release Science program, which provides time to selected projects early in the telescope's mission. This program allows the astronomical community to quickly learn how best to use Webb's capabilities, while also yielding robust science.

The cluster is so massive that its powerful gravity bends the light from galaxies far behind it, making the background objects appear larger and brighter in a phenomenon called gravitational lensing. Shown in this Hubble image, the mammoth Abell 2744 cluster is located about 3.5 billion light-years away. Credits: NASA Subscribe to our YouTube channel Follow us on Instagram |
