Description:

The Iris Nebula, also known as NGC 7023 and Caldwell 4, is a bright reflection nebula located in the constellation Cepheus. It is one of the most photographed objects in the night sky due to its vibrant colors and striking appearance. The nebula measures about six light-years across and is illuminated by a young, hot star at its center.

The light from the star reflects off of the surrounding clouds of interstellar dust and gas, creating the beautiful blue and red hues that are visible to telescopes on Earth. The nebula gets its name from its resemblance to the flower of the same name. In fact, it is often referred to as the "Iris Flower Nebula." The Iris Nebula is located about 1,300 light-years away from Earth and is relatively small compared to other nebulae, making it a relatively young celestial object. Despite its small size, it is an active site of star formation and contains several newly forming stars within its folds.

Distance: 1,300 light-years
