The IC 1623 A and B are located 270 million light-years away and are merging. As the two galaxies crash together, they are intersecting and feeding high levels of star formation.

James used three of his instruments to capture the picture. The different features of the merging galaxy were seen by the different instruments. The interacting galaxy system is bright at the wavelength of the sun, which makes it a perfect proving ground for the study of glowing galaxies.

This image from the NASA/ESA/CSA James Webb Space Telescope depicts IC 1623, an entwined pair of interacting galaxies which lies around 270 million light-years from Earth in the constellation Cetus. The two galaxies in IC 1623 are plunging headlong into one another in a process known as a galaxy merger. Their collision has ignited a frenzied spate of star formation known as a starburst, creating new stars at a rate more than twenty times that of the Milky Way galaxy.

The birth of new stars is caused by the tug of clouds of dust and gas caused by the gravity of the two galaxies. The merging of the two galaxies may create a new black hole.

This image from the NASA/ESA Hubble Space Telescope depicts IC 1623. It combines data from Hubble’s ACS and WFC3 instruments, gives a familiar visible-light view of these colliding galaxies, where the centres of the individual galaxies are more obscured by dark dust.

The Hubble Space Telescope's Advanced Camera for and Wide Field Camera 3 were used to image the merging pair of galaxies. The image shows the same amount of light as the human eye would see. Parts of the image are obscured by dust in the center of the universe. By comparing the image to the one above, you can see how the instruments can peer through the dust to see what is underneath.
