James Webb Space Telescope Discovers Twin Stars Behind HH 797

Previously thought to be a single star, the two stars are producing parallel outflows, causing a series of shocks.

The James Webb Space Telescope has revealed that a Herbig-Haro object, known as HH 797, previously thought to be the result of a single baby star, is actually the work of two stars.
These stars are so close together in the sky, they appear as one and each is producing its own dramatic outflow.
The HH 797 is located near the young open star cluster IC 348, just east of the Perseus constellation's dark cloud complex.
Webb's infrared vision has allowed astronomers to detect the infrared light thrown out in the stars' jets, picking up molecules excited by the strong shockwaves, including hydrogen and carbon monoxide.
The high resolution of the JWST image reveals that what was thought to be outflow is actually two parallel jets, each causing its own series of shocks.
