    The James Webb telescope reveals a spectacular image of the Cartwheel galaxy

    Nasa published an impressive image on Tuesday from a galaxy located 500 million light years away, the Wagonwheel Galaxy, whose rings are seen with unprecedented clarity by the new James Webb Space Telescope.

    Like our Milky Way, astronomers They believe that the Wagonwheel Galaxy was once a spiral galaxy. But a spectacular event gave it its shape: the collision with another smaller galaxy (not visible in the image).

    From the center of the collision two rings formed, similar to the ripples in concentric circles caused by a pebble dropped into water. This is what gave it its evocative name.

    The first ring, more to the center, is very bright, and the second, on the outside, has been expanding for 440 million years. And, as the ring expands, it collides with surrounding gas, triggering star formation.

    More details

    This galaxy has already been observed by the Hubble Space Telescope, but James Webb's infrared capabilities reveal new details that were previously hidden, allowing him to see through a large number of dust.

    The composite image, derived from observations by two of the telescope's science instruments, also includes two other smaller galaxies, as well ; like many others in the background.

    The Wagon Wheel galaxyit is still in a “transitional” state, according to what NASA has said in its statement. Although the James Webb Telescope “gives us a view of (its) current state, it also gives us an idea of ​​what has happened to it in the past, and how it will evolve in the future.”

    The $10 billion James Webb telescope was launched into space about seven months ago and is 1.5 million kilometers from Earth.< /p>
