Webb Telescope Reveals Cartwheel Galaxy 500 Million Light Years Away

TEMPO.CO, JakartaTelescope Webb reveals the Cartwheel Galaxy, which is 500 million light years from Earth. The observatory’s $10 billion infrared gaze provides a rare view of the Cartwheel and its two smaller companion galaxies against the backdrop of many other galaxies.

Scientists say the display will provide new details about star formation and central black holes galaxy that. Its appearance, like a wagon wheel, is the result of an intense, high-speed collision between a large spiral galaxy and a small galaxy.

Other telescopes, including the Hubble Space Telescope, have previously examined Cartwheel, which is in the Sculptor constellation. But the dramatic galaxy has been shrouded in mystery, given the amount of dust that obscures the view.

James Webb’s images and related NASA videos also provide a fresh look at how the Cartwheel Galaxy has changed over billions of years. “This image of Cartwheel and its companion galaxy is a composite of the Webb Near Infrared Camera (NIRCam) and the Central Infrared Instrument (MIRI), which reveal details that are difficult to see in individual images alone,” NASA said.

“Webb’s observations captured the Cartwheel in a very transient stage. The shape the Cartwheel Galaxy will eventually take, given these two competing forces, remains a mystery. However, this snapshot provides perspective on what happened to the galaxy in the past and what it will do. in the future,” said NASA

Collisions of galactic proportions cause different cascades, Cartwheel is no exception. The collision mainly affects the shape and structure of the galaxy.

The Cartwheel Galaxy features two rings — a bright inner ring and a colorful ring around it. These rings expand outward from the center of the impact, like ripples in a pond after a rock is thrown into it.

Because of this characteristic, astronomers call it a ‘ring galaxy’, a structure that is less common than spiral galaxies like our Milky Way. The bright core contains large amounts of hot dust with the brightest areas being home to giant young star clusters.

On the other hand, the outer ring, which has been expanding for about 440 million years, is dominated by star formation and supernovae. As this ring expands, it plows into the surrounding gas and triggers star formation.

Studying the finer details of the dust that inhabits galaxies, however, requires Webb’s Central Infrared Instrument (MIRI).

The MIRI data is colored red in this composite image, revealing regions within the Cartwheel Galaxy that are rich in hydrocarbons and other chemical compounds, as well as silicate dust, like most of the dust on Earth.

These regions form a series of spiral radii that essentially form the galaxy’s skeleton. The radii were clearly visible in previous Hubble observations released in 2018, but they become much more prominent in this Webb image.

While Webb gives us an idea of ​​the current state of the Cartwheel, it also provides insight into what happened to this galaxy in the past and how it will develop in the future.

Last month, dazzling and unprecedented telescope images of ‘star nurseries’, dying stars shrouded in dust and a ‘cosmic dance’ between clusters of galaxies were revealed to the world for the first time.

This ends months of waiting and rushed anticipation as people around the world are treated to the first batch of treasure troves of images that will culminate in the earliest appearances of the universe.

Webb’s infrared capabilities mean that he can ‘look back in time’ in just 100-200 million years from the Big Bang, which allowed him to take pictures of the first star to shine in the universe more than 13.5 billion years ago.

The first images of a nebula, an exoplanet and galaxy cluster sparked great celebrations in the scientific world, and were hailed as a ‘big day for mankind’. Researchers will soon begin to learn more about the mass, age, history, and composition of galaxies, as Webb seeks to explore the universe’s earliest galaxies.
