If you don’t have the opportunity to visit an astronomical observatory, the NASA website has an intersting page named “Astronomy Picture of the Day” (https://apod.nasa.gov/apod/archivepix.html).
Here I selected for you a fantastic view from an island in the Maldives. Sea and sky are glowing, but what glows?
In the sea, the impressive blue glow is bioluminescence, is produced by a single-celled plankton stimulated by the lapping waves. The plankton use their glow to scare and illuminate predators.
In the sky there are the familiar glows of stars and nebulas. The white band rising from the artificially-illuminated green plants is created by billions of stars in the central disk of our Milky Way Galaxy. It is also visible the star cluster Omega Centauri, toward the left, and the Southern Cross in the center. Red-glowing nebulas include the bright Carina Nebula, just right of center, and the expansive Gum Nebula on the upper right.
