This is a picture of FS Tau, a young star in the constellation Taurus, and its surroundings. FS Taurus, located in a star-forming region about 450 light-years from Earth, is a young star that is thought to be only about 2.8 million years old.

According to the National Aeronautics and Space Administration (NASA), FS Taurus consists of a binary star “FS Tau A” that shines brightly near the center of the image, and a jet (slender jet) to the left and right in the upper right of the binary star “FS Tau A”. It is a multi-star system consisting of the star FS Tau B (FS Tau B), which emits a constricted, high-speed flow of gas.
The two stars that make up Star A are both classified as young variable stars called “T Tauri stars.” Hydrogen fusion reactions have not yet begun in the centers of T Tauri stars, which will later evolve into main-sequence stars, and the energy released when the star contracts under its own gravity and surrounding matter accumulates. It is said to shine.
On the other hand, the even younger B star is thought to be a protostar in the process of transitioning to a T Tauri star, and the star itself is still surrounded by a protoplanetary disk of dust and gas. Because the Earth is positioned to view the disk from the side, the image shows what appears to be the dark edge of the disk and the bright sides of the disk from which jets flow.
B stars are also classified as “Herbig-Haro objects.” A Herbig halo object is a bright nebula-like object that can be seen around a young star. Gas flowing out from the young star as a stellar wind or jet collides with surrounding gas and dust clouds, and the excited material is released. It is believed that light is emitted. The light blue colored jet has an asymmetric structure, which is thought to be due to the fact that matter is ejected at various speeds.
The image at the beginning was created based on data acquired by the Hubble Space Telescope (HST)’s High-Performance Camera for Sky Surveys (ACS). ) published on March 25, 2024.
