NASA just shared a new James Webb image showcasing a cosmic fingerprint created by two stars locked in a celestial dance.
captured the image of the cosmic fingerprint while peering at a star system 5,300 light-years away. The duo of stars is known as Wolf-Rayet 140 , and each ring surrounding the system was created when the two stars passed close together. When this happens, their stellar winds meet, compressing the gasses the stars blow into space, turning them into dust.Judy Schmidt discovered the data
in Webb’s treasure trove of observations. As I noted upon that release, the dust rings we see – which make up the phenomenon that makes this pair so brilliant – are an indicator of time itself. The stars pass each other every 7.94 years. The rings in the newest James Webb image add up to 160 years’ worth of dust trails. The resulting cosmic fingerprint, as NASA describes it, is one of the most intriguing phenomena we’ve seen from the telescope’s data – despite the sheer beauty ofWebb’s ability to capture infrared light makes capturing images of these phenomena so effective. If we were looking at this system using visible light, we wouldn’t be able to properly study the dust rings of these wind binary stars.
Thankfully, because of the power behind James Webb’s infrared instruments, scientists will finally have a chance to dig deeper and discover more about these spectacular celestial happenings.
