A masterpiece: The clearest galaxy image ever has emerged.

Astronomers have come up with a galactic masterpiece... The most detailed image of the Sculptor Galaxy has emerged to date.

The Sculptor Galaxy resembles our Milky Way in many ways. However, since we are inside the galaxy, it is not possible to see it all from Earth. On the other hand, the Sculptor Galaxy is in an ideal position for astronomers to make a good observation. Now, astronomers have created an ultra-detailed image of the Sculptor Galaxy, covering an area of ​​approximately 65,000 light-years wide.

Astronomers have obtained an ultra-detailed image that reveals the never-before-seen features of the Sculptor Galaxy. Using the European Southern Observatory's (ESO) Very Large Telescope (VLT) in Chile, this nearby galaxy was observed simultaneously in thousands of different colors. According to the statement, a huge amount of data was collected to create an image on the scale of the entire galaxy, covering the lives of the stars within the galaxy.

“Galaxies are incredibly complex systems, and we’re still trying to fully understand them,” says ESO researcher Enrico Congiu. “The Sculptor Galaxy is in an ideal position: close enough to decipher its internal structure, but also large enough to see it in its entirety.”

The building blocks of a galaxy — stars, gas and dust — emit light in different colours, ESO says. So the more shades of colour you can find in an image of a galaxy, the more information you can learn about its inner workings. While traditional images show just a few colours, the new map contains thousands, giving scientists detailed information about the age, composition and motion of the stars, gas and dust.

To create this map of the Sculptor Galaxy, also known as NGC 253, researchers used the Multi-Unit Spectroscopic Observatory (MUSE) to scan the galaxy for more than 50 hours. More than 100 exposures were combined to cover an area of ​​about 65,000 light-years.

Co-author Kathryn Kreckel from the University of Heidelberg in Germany explains the power of this map: “We can zoom in on regions where stars are forming, almost on the scale of individual stars, but we can also analyze the entire galaxy as a whole.”

In their initial analysis of the data, the team identified about 500 planetary nebulae – regions of gas and dust emanating from stars that have reached the end of their life – in the galaxy. “Finding planetary nebulae allows us to confirm the distance to the galaxy, which is the basis for all studies of the galaxy,” says Professor Adam Leroy from Ohio State University.

Future projects will use this map to investigate how gas flows, how its composition changes, and how stars form across the galaxy.
