NASA's New Images of Galaxy Interactions

NASA has created a stunning composite image using data from the Hubble and James Webb Space Telescopes (JWST) to showcase the cosmic dance of two galaxies, NGC 2207 and IC 2163. The two galaxies are expected to slowly merge into one giant galaxy. At the center of this merger is a supermassive black hole.

They are approaching each other

Researchers say that NGC 2207 and IC 2163 passed close to each other years ago and are now gravitationally moving towards each other again. This interaction causes the gas clouds inside the galaxies to compress, triggering the birth of new stars.

In ultraviolet light images from the Hubble Telescope, the glow of newborn stars is clearly visible in their blue hue, revealing how interactions between galaxies accelerate star formation.

The Birth and Death of Stars

The interaction of galaxies brings not only the birth of stars but also the explosion of powerful supernovas. These explosions compress the surrounding gas and allow new stars to form. This cycle represents the continuous birth and death of stars in the universe.

The James Webb Space Telescope’s mid-infrared camera is revealing in detail the distribution of dust in galaxies. This dust is another important indicator of star formation in galaxies. The merging process of galaxies provides an important window into the complexity of dynamic structures and stellar life cycles in the universe.
