​​When two galaxies collided, this is what the aftermath looked like

Have you ever wondered what it would look like if two galaxies collided together? In my opinion, the answer to this question is pretty spectacular! The James Webb space telescope of NASA has captured images of the Cartwheel

There is also a possibility that it may be able to explain how the galaxy's stars were formed and how the black hole at its center came to be. Galaxy and two companion galaxies, providing insight into how the galaxy has evolved over billions of years - yes billions of years - over which it has existed.

As seen by the James Webb space telescope, here is a brand new image of the Cartwheel Galaxy. Webb isn't just a snapshot of the galaxy's current state, but it's also a glimpse into its future,' the telescope's Instagram account said this week.

'We believe this galaxy started as a spiral galaxy before colliding with a smaller galaxy hundreds of millions of years ago. Currently, it is made up of two rings - a bright inner ring and a surrounding, colorful ring. They both ripple outward from the center.'

NIRCam and MIRI data were used to create a 'composite view' of the stunning image, they explained. While NIRCam reveals previously unseen young stars, MIRI shows regions rich in hydrocarbons and chemical compounds, as well as silicate dust, similar to Earth's dust.

Scientists added in a separate press release that the galaxy, located approximately 500 million light-years away in the Sculptor constellation, obtained its appearance 'much like the wheel of a wagon as a result of an 'intense event' – an intense collision between a

A large spiral galaxy and a smaller galaxy are not visible in this image, they explained. 'Galactic collisions are characterized by a cascade of smaller events between the galaxies involved.'

'The collision had the greatest effect on the shape and structure of the galaxy,' the researchers wrote. 'The Cartwheel Galaxy sports two rings — a bright inner ring and a colorful surrounding ring.

These two rings spread outward from the center of the collision, like ripples in a pond after a stone is thrown in. These characteristics make it a 'ring galaxy,' which is less common than spiral galaxies like our own.

They explained that the galaxy has previously been photographed and examined, but the dust surrounding it had obscured the view. The ability of Webb to detect infrared light has revealed new insights into how the Cartwheel works,' they wrote.

As Webb observed, the Cartwheel is in a very transitory stage. Before the collision, it appears to have been a normal spiral galaxy like the Milky Way. Webb not only provides us with an overview of the Cartwheel's current state but also provides insight into what has happened to it in the past and how it will continue to evolve.'
