This new image of a galaxy called NGC 7469, located 220 million light-years away in the constellation of Pegasus.
It is a spiral galaxy like our own Milky Way and is positioned so that it appears directly in front of us.

In addition to these The main galaxy You can also see more distant galaxies in the background, as well as the companion galaxy NGC 5283, which can be seen in the lower left of the image, Digitartlends reported.
Perhaps the most obvious feature in the image is the bright red star shape jutting out from the galactic centre, called an active galactic nucleus, or AGN.
This is a very bright region where dust orbits the supermassive black hole at the center of the galaxy, eventually falling in and releasing heat and light as it goes.
“The standout feature of this image is the striking six-pointed star that aligns perfectly with the heart of NGC 7469,” Webb scientists explain. “Unlike a galaxy, this is not an actual celestial body, but an imaging artifact known as diffraction spike, caused by unresolved bright AGN.
Diffraction spikes are patterns produced when light bends around the sharp edges of a telescope.
Webb’s primary mirror consists of hexagonal segments that each have edges for the light to emit, giving six bright heights.
There are also shorter, lighter screws, created by diffraction from the vertical strut that help support the secondary Webb mirror.”
This region was studied using three of Webb’s instruments, the mid-infrared instrument (MIRI), the near infrared camera (NIRCam), and the near infrared spectrometer (NIRSpec).
This AGN is special because near it it hosts a starburst region, where stars are forming at a rapid rate.
Webb’s research aims to investigate the relationship between this NGN and the nearby starburst region, and the role dust plays between the two.
