No, the Crab Nebula is not part of the arm of Sagittarius. It is located in the constellation Taurus and is the remnant of a supernova explosion observed in 1054 AD. The nebula is situated in the Perseus arm of the Milky Way galaxy, rather than the Sagittarius arm.
It's difficult to be precise because of the great distance from us (~6,500 light years). It either lies on the rim of the Orion arm or the rim of the Perseus rim. [See related link]
The Sagittarius arm.
The Sagittarius Arm is one of the major spiral arms of the Milky Way galaxy, located between the Scutum-Centaurus Arm and the Perseus Arm. It is named after the constellation Sagittarius, where it is prominently situated. This arm contains several star clusters, nebulae, and a significant amount of interstellar gas and dust, playing a crucial role in the formation of new stars. The Sagittarius Arm is important for understanding the structure and dynamics of our galaxy.
Our solar system is located in the Orion Arm, also known as the Orion Spur, which is a minor arm of the Milky Way galaxy. The Orion Arm sits between the larger Perseus Arm and the Sagittarius Arm. It contains several notable stars and structures, including the Orion Nebula and the Pleiades star cluster. This region of the galaxy is rich in star formation and other celestial phenomena.
We are located in the Milky Way galaxy, specifically in a spiral arm called the Orion Arm or Orion Spur. This arm is situated between two larger arms, the Perseus Arm and the Sagittarius Arm. Our solar system is about 27,000 light-years from the galactic center, which is home to a supermassive black hole known as Sagittarius A*. The Milky Way itself is part of the Local Group of galaxies, which is within the larger Laniakea Supercluster.
The Horsehead Nebula is located in the Orion constellation, specifically within the Orion Molecular Cloud Complex. It lies approximately 1,500 light-years away from Earth and is part of the Milky Way galaxy's Orion Arm, which is a minor spiral arm. The nebula is a region of star formation, characterized by its distinctive dark silhouette against the background glow of ionized gas and nearby stars.
The Milky Way galaxy has several major arms, with the five primary ones being the Perseus Arm, the Norma Arm, the Scutum-Centaurus Arm, the Sagittarius Arm, and the Orion Arm. The Orion Arm, where our solar system is located, is a minor arm situated between the larger Perseus and Sagittarius arms. Each arm contains stars, gas, and dust, contributing to the galaxy's structure and dynamics.
The Sun is located in the Orion Arm, also known as the Orion Spur, of the Milky Way galaxy. This arm is situated between the larger Perseus Arm and the Sagittarius Arm. The Sun is about 26,000 light-years from the galactic center, placing it in the outer region of the spiral galaxy.
Oh, my dear friend, thank you for your curiosity! In the magnificent canvas that is our Milky Way galaxy, we have a total of four beautiful arms: the Scutum-Centaurus, the Sagittarius, the Perseus, and the Outer arm. Each one swirls in harmony, adding vibrant colors to our galactic masterpiece. Let's appreciate their unique beauty together, shall we?
It is called the local spur arm. as we are not directly on the arm of a galaxy just between the sagittarius and perseus arms.
It is considered a limb, not an arm. And the loss of a limb does not necessarily mean the hermie crab has died, but is a hermit crab that is very stressed. One needs to double check their tank perimeters to make sure they are correct.
Earth is located in the Milky Way galaxy within the Orion Arm, also known as the Orion Spur. This arm is situated between the larger Perseus Arm and the Sagittarius Arm. Specifically, Earth is about 27,000 light-years from the galactic center, which is in the direction of the constellation Sagittarius. The Milky Way itself is a barred spiral galaxy, with Earth positioned in one of its spiral arms.
