The strange cosmic ripples have prompted alien origin theories.
"The six-pointed blue structure is an artifact due to optical diffraction from the bright star WR140 in this #JWST MIRI image," McCaughrean continued. "But red curvy-yet-boxy stuff is real, a series of shells around WR140. Actually, in space. Around a star." He added that he doesn't understand "why there are discrete, separated shells rather than a spiral structure," but scientists are now working to explain the intricacies of the observations.
In fact, Ryan Lau, an astronomer at NOIRLab and principal investigator of the project that acquired the observations, replied to McCaughrean's Twitter thread. He said, "our paper on this has been submitted, so please stay tuned for the full story."The new observation is another indicator of the immense power of the $10 billion James Webb space observatory, only two short months into the telescope's science operations.
