NASA has released a stunning picture of planetary nebula ESO 455-10 by NASA / ESA Hubble Space Telescope.
The Planetary Nebula is a type of emission nebula consisting of expanding shells of gases that exit stars late in their lives.
These objects are usually no larger than the diameter of a light year, and form at the end of the life of a star of intermediate mass between 1 and 8 times that of the Sun.
They have a relatively rounded compact appearance rather than the chaotic sharp shapes of other nebulae – hence their name, which was given due to the similarity of planetary disks when viewed with instruments from the late 1700s, when the nebula was first discovered Was.
Planetary nebulae are considered important in galactic enrichment because they distribute their elements, especially heavy metal elements originating inside a star, into the sensory medium that forms the next generation of stars.
Our Milky Way Galaxy has about 20,000 planet nebulae. Most of them are oriented towards the disk plane of the Milky Way, but some are present in the halo and bulge.
ESO 455-10, also known as IRAS 17277-3058, is one such planetary nebula, located in the constellation of Scorpius.
The Hubble astronomers stated, “The oblique spheres of ESO 455-10, already held tightly together as layers of their central star, give not only this planetary nebula its unique appearance, but also about the nebula. Give information, ”said Hubble astronomers.
“Seen in a region of stars, the distinct asymmetrical arc of material on the north side of the nebula is a clear indication of the interaction between ESO 455-10 and the interstellar medium.”
“The interstellar medium is the material – consisting of matter and radiation – between star systems and galaxies,” he explained.
“The center of ESO 455-10 allows Tara Hubble to see the gas and dust of the nebula, the surrounding interstellar medium, and light from the star.”
