The following articles contain lists of nebulae: List of dark nebulae; List of diffuse nebulae; List of largest nebulae; List of planetary nebulae; List of protoplanetary nebulae; List of supernova remnants
Diffuse nebulae can be divided into emission nebulae, reflection nebulae and dark nebulae. Visible light nebulae may be divided into emission nebulae, which emit spectral line radiation from excited or ionized gas (mostly ionized hydrogen ); [ 25 ] they are often called H II regions , H II referring to ionized hydrogen), and reflection nebulae ...
feature: which geographic objects should be displayed (corresponds in the map data to the name of the field under the objects field). The default is value countries. ids of geographic entities: The actual parameter names depend on the base map and the selected feature. For example, for the above mentioned world map the ids are ISO country codes.
There are several astronomical catalogues referred to as Nebulae and Star Clusters. A Nebula is a cloud of dust and gas inside a galaxy. Nebulae become visible if the gas glows, or if the cloud reflects starlight or obscures light from more distant objects.
This template is designed for maps of the world or east hemisphere, showing historical borders and detailed geography. The dates refer to the year depicted in the maps, not when they were made. Note: Please only include maps based on the Topographic_map#Global_1-kilometer_map , and only maps showing historical information about countries ...
NGC 604, one of largest nebulae (H II region) is located in the Triangulum Galaxy (viewed by the Hubble Space Telescope). Below is a list of the largest known nebulae so far discovered, ordered by actual diameter.
A celestial map by the Dutch cartographer Frederik de Wit, 1670. A star chart is a celestial map of the night sky with astronomical objects laid out on a grid system. They are used to identify and locate constellations, stars, nebulae, galaxies, and planets. [1] They have been used for human navigation since time immemorial. [2]
