Some stars create a ‘fingerprint’ in the image taken by the James Webb Space Telescope

Two intertwined stars create what appears to be a “fingerprint” in space. Nasa post a photo Marry duo caught by James Webb Space Telescopewhich shows at least 17 rings of dust around the stars.

Two stars, known as Wolf-Rayet 140, create rings of dust in space that look like fingerprints in an image captured by NASA’s James Webb Space Telescope.


The images were taken using the telescope’s mid-infrared instrument, created by NASA and the European Space Agency.

The stars, collectively known as Wolf-Rayet 140, are located 5,000 light-years from Earth, NASA said in a press release. NASA explained that each dust ring forms when the two stars come close to each other during their orbit, causing the two to emit gas to compress and form the rings.

“Changing gas into dust is a bit like turning flour into bread: it requires specific conditions and ingredients,” NASA said of the dust rings.

It takes about eight years for each ring to form.

“We’re looking at over a century of dust production from this system,” astronomer Ryan Lau said.

NASA has revealed that the pair are nearing the end of their life, which will lead to their collapse and the formation of a black hole. Stars classified as Wolf-Rayet have a mass at least 25 times the mass of the Sun and pump large amounts of gas.

According to NASA, the pair may have lost more than half of their original mass over time.

Astronomers also believe the winds from the stars swept the area around any debris that could warp the rings, which is why they can be seen clearly through telescope.

“There will likely be more episodes that become so faint and scattered that even Webb can’t see them in the data,” NASA said.

Matter derived from Wolf-Rayet stars can accumulate and form new stars. NASA has revealed that there is evidence showing that the Sun may have formed this way as well.

Only 600 Wolf-Rayet stars have been found by astronomers in the sky, but they say there must be at least a few thousand.
