NASA's James Webb Space Telescope, Hubble Space Telescope reveal dance of galaxies

tech.hindustantimes.com:

In an extraordinary cosmic collaboration, NASA's James Webb Space Telescope and the Hubble Space Telescope have partnered to explore the vastness of a distant galaxy cluster and they have unveiled a mesmerising and vibrant panorama of the universe. This groundbreaking venture, capturing the galaxy cluster known as MACS0416, employs a fusion of visible and infrared light, producing one of the most extensive snapshots of the universe to date.

Situated a staggering 4.3 billion light-years away from Earth, MACS0416 comprises two colliding galaxy clusters destined to merge into an even grander cosmic entity. The composite image not only showcases a multitude of galaxies beyond the cluster but also unveils dynamic sources, likely influenced by gravitational lensing- a phenomenon altering and intensifying light from distant celestial sources.

This celestial cluster marks the inaugural subject of a revolutionary Hubble initiative, the Frontier Fields program, initiated in 2014, aiming to deliver unprecedented, super-deep insights into the universe.

Hubble Telescope, a pioneer in detecting faint and youthful galaxies, sees its capabilities expanded by the James Webb Space Telescope's infrared perspective, delving deeper into the cosmic dawn. The research team, incorporating three observation epochs from both telescopes, alongside a fourth from the CANUCS research team, identified 14 transients—objects exhibiting varying brightness over time.

Twelve of these phenomena were pinpointed in highly magnified galaxies due to gravitational lensing, likely representing momentarily intensified individual stars or multi-star systems. The remaining two transients, residing in moderately magnified background
