The beautiful chaos of two merging galaxies shines in the latest image captured by the James Webb Space Telescope.

Vice President Kamala Harris and French President Emmanuel Macron saw Webb’s new image, along with a new composition of the Pillars of Creation captured by the space observatory, during a visit to NASA headquarters in Washington on Wednesday.

The Webb telescope, designed to observe faint and distant galaxies i other worldsis an international mission between NASA and its partners, the European Space Agency and the Canadian Space Agency.

The pair of galaxies, known as II ZW 96, is located about 500 million light-years from Earth in the constellation Delphinus. The points of light in the background of the image represent other distant galaxies.

The spinning shape of the two galaxies was created when they began to merge, disrupting their individual shapes. Galactic mergers occur when two or more galaxies collide in space.

Bright regions where stars are born shine in the center of the image, while the spiral arms of the lower galaxy are twisted by the gravitational pull of the merger.

Stars form when clouds of gas and dust collapse inside galaxies. When galaxies merge, more star formation is triggered, and astronomers want to know why.

Bright areas of star birth are of interest to astronomers using Webb because they appear even brighter when viewed in infrared light.

Although infrared is invisible to the human eye, Webb’s capabilities allow it to spy on previously unseen aspects of the universe.

Webb’s Near Infrared Camera and Mid-Infrared Instrument were used to capture the new image.

Astronomers are using the observatory to study how galaxies evolve and, among other topics, why bright infrared galaxies like II ZW 96 glow with infrared light, reaching a luminosity of more than 100 billion times that of our sun.

Researchers have turned Webb’s instruments on merging galaxies, including II ZW 96, to pick out fine details and compare the images with those previously taken by ground-based telescopes and the Hubble Space Telescope. Together, the observations may reveal a more complete picture of how galaxies change over time.
