Every picture you take NASA’s James Webb Telescope It surprises the community of researchers and fans. The most recent one is a “footprint in space,” which is actually two stars. Another beauty in the universe.

According to NASA, there are at least 17 concentric rings of dust that are born from two stars, 5 thousand light-years from Earth. This duo is known as Wolf Wright 140 (WR 140).
“We’re looking at more than a century of dust production from this system,” said Ryan Lau, an astronomer at the National Research Laboratory for Optical Infrared Astronomy (NOIRLab).
The image also shows how sensitive this telescope is. Before that, we could only see two rings of dust using ground-based telescopes. Now we see at least 17 of them.”
“Although Wolf-Rayet stars are rare in our galaxy because they are short-lived relative to the half-lives of stars, they probably produced a lot of dust throughout the history of the galaxy before they exploded and formed black holes,” Patrick said. Morris, an astrophysicist at the California Institute of Technology in Pasadena, California.

Wolf-Rayet 140 is located in the constellation Cygnus, in the center of the triangle formed by Deneb, Cygni and Delta Cygni. In cosmic dust production mode, some stars expel silicon and carbon-enriched debris into the wider universe: These stars are called Wolf-Rayets.
Its outer layers are enriched Oxygen, nitrogen, silicon and carbon.
These stars are born with a mass at least 25 times that of the Sun. As it nears the end of its life, it will likely collapse into a black hole.
Thanks to science instruments on NASA’s James Webb Space Telescope Not only are dust rings detected, but infrared light, made up of a range of wavelengths invisible to the human eye, is also detected.
The telescope’s Medium Infrared Instrument (MIRI) spectrometer also revealed the composition of the dust.
“I think with NASA’s James Webb Telescope,” Morris says. “We will learn a lot about how these stars form interstellar matter and stimulate the formation of new stars in galaxies.”
