'We’re looking at over a century of dust production from this system.'
That's not an optical illusion caused by Webb's cameras; the new image captures a duo of stars, known as Wolf-Rayet 140, some 5,000 light-years from Earth, and the ghostly ripple rings created by their interacting solar winds.
James Webb's Mid-Infrared Instrument is well suited to studying the dust rings around Wolf-Rayet 140 because it detects the longest infrared wavelengths, meaning it can see cooler objects like the dust rings.The Wolf-Rayet 140 system contains a type of star called a Wolf-Rayet star. This is an O-type star, which is born with roughly 25 times more mass than our Sun and is nearing the end of its life. These stars typically form a black hole when they die.
