#binary star system

NASA's James Webb Space Telescope captures the infrared light from bright protostars in young star system FS Tau. FS Tau A, a pair of protostars that creates the largest diffraction pattern slightly to the left of center, is about half the mass of our Sun. FS Tau B, the orange protostar slightly right of center, is thought to be responsible for the red (molecular hydrogen) and orange (soot-like molecules known as polycyclic aromatic hydrocarbons) outflows that we see amid the dusty region. The blue ridges are areas where light has been scattered by dust.

The bright star at the center of NGC 3132, the Southern Ring Nebula, plays a supporting role in sculpting the nebula's rings — a dimmer companion star hidden along one of its diffraction spikes is the true source, having ejected at least eight layers of gas and dust over thousands of years. Webb's near-infrared view also reveals countless background galaxies through the nebula's transparent regions.
