A new image from the NASA/ESA Hubble Space Telescope shows a jet emerging from the cocoon of the multistar system FS Tau.

FS Tau It is located about 450 light years away in the constellation Taurus.
The system is part of the Taurus-Auriga region, a collection of dark molecular clouds that is home to many newly formed young stars.
FS Tau, also known as HH 157 or TIC 58437437, is only about 2.8 million years old, making it an extremely young star system.
FS Tau is a multi-star system consisting of FS Tau A, a bright star-like object near the center of the image, and FS Tau B, a bright object on the far right hidden by a dark vertical dust lane. ''' said the Hubble astronomer.
“The young object is surrounded by gently illuminated gas and dust in this stellar nursery.”
“FS Tau B is a protostar surrounded by a protoplanetary disk. A protoplanetary disk is a pancake-like collection of dust and gas left over from star formation that eventually coalesces to form a planet. It will be.”
“A thick lane of dust seen almost head-on separates what is believed to be the illuminated surface of the flared disk.”
“FS Tau B is probably T TauriAlthough nuclear fusion has not yet begun, it is a type of young variable star that is beginning to evolve into a hydrogen-fueled star similar to the Sun. ”
“Protostars glow because of the thermal energy released when the gas clouds from which they formed collapse, and from the accretion of material from nearby gas and dust.”
“Variable stars are a type of star whose brightness changes significantly over time.”
“FS Tau A itself is a Tauri T binary system, consisting of two stars orbiting each other,” the researchers added.
“Protostars are known to emit fast-moving columns of energetic material called jets, and FS Tau B provides a striking example of this phenomenon.”
“Protostars are the source of the unusual, asymmetric, double-sided jets that appear blue here.”
“Their asymmetric structure may be due to differences in the rate at which mass is ejected from the object.”
“FS Tau B is Herbig halo object,” they said.
“Herbig halo objects form when jets of ionized gas emitted by young stars collide at high speed with nearby clouds of gas and dust, forming bright nebular patches.”
