Horsehead, Egg and Eskimo: in the new game from NASA you have to guess the nebula by its shape

In November, NASA traditionally celebrates #NebulaNovember —the month of November is dedicated to nebulae. This year the game appeared

 Name That Nebula (“Name the nebula”). The user is asked to guess the name of the nebula by its appearance.

In general, almost all known nebulae haveat least two names - one official, the other simpler, often chosen based on external similarity. For example, the Horsehead Nebula is officially called IC 434, but it does look like a horse's head. It is approximately 3.5 light years in diameter and lies south of the star Alnitak (Zeta Orionis), the eastern star of Orion's Belt.

The game Name That Nebula is exactly this - the participant must guess what the scientists reminded of the nebula when they called it. There are three levels of difficulty.

The game is available here.

Nebulae are real “favorites”public, some of the most famous space attractions. This is a section of the interstellar medium that stands out due to its radiation or absorption of radiation against the general background of the sky.

Previously, astronomers called this any celestialobjects that are motionless relative to the stars, having, in contrast to them, a diffuse, blurry appearance, like a small cloud (the Latin term nebula used in astronomy for “nebula” means “cloud”). Over time, it became clear that some of them, for example, the Orion nebula, consist of interstellar gas and dust and belong to our Galaxy. Other, “white” nebulae, like those in Andromeda and Triangulum, turned out to be giant star systems. Today, there are 1,500 known planetary nebulae in our Galaxy, which consists of 200 billion stars.
