2023 December 19 - NGC 1499: The California Nebula

In today's image, we see the California Nebula also known by the catalog designation of NGC 1499. This is an example of an emission nebula where light from a hot star ionizes the gas nearby and causes it to glow. The red color is associated with hydrogen gas, the most common element in the universe.
