Another masterstroke for James-Webb with this surprising wheel-shaped galaxy composite image. Sharp views from powerful space telescopes reveal never-before-seen details of these galaxies that collided about 400 million years ago. What do they show us?

image of car wheel galaxy taken by Hubble in 2007 and revisited in 2018 we were all blown away by the beauty and complexity of this ring galaxy distorted by the violent collision. Observations on the look andultraviolet through the famous entertaining space telescope astronomer for the detail of its outer crown, burned by the birth of many peoplebintangthe active center region and the spokes, curved in a spiral, are shock-resistant.
This time, another vision of James Webbthe L’infrared, offers in-depth knowledge of this interactive galaxy located 500 million light years from Earth. We therefore discovered, not without fascination and vertigo, what researchers had never seen before, or only bad: skeletons of dust and gas of ESO 350-40 (its original name), as well as its foam black hole center.
Very active galaxy
In the distant past, this so-called Chariot Wheel galaxy looked like our own galaxy, Milky Waywith a spiral shape like whirlwinduntil interactions with other members of the galaxy cluster cause large-scale collisions. speed with the galaxy, lies here outside the frame. It happened about 400 million years ago, and now we admire and study what happened, its evolution, its changes morphology and the stellar population under the influence of the shockwave in awan from dust. The two concentric rings were like waves created on the surface of the water after throwing a pebble. It unclear the largest form a shimmering crown of young stars whose matrix has been fertilized by the intense compression of the case. The spectacle is even clearer within the inner ring and in the heart of the galaxy, seen in a full boiling state, as shown by James-Webb’s sharp gaze reveal star clusters that were once hidden by a thick veil of dust.
A composite image that combines observations from Miri and Nircam can also see fine detail from nearby galaxies and wash away many other galaxies, spread out over the background billions of light years away. A dazzling spectacle, “and this is just the beginning”.
