Astronomers capture the most exquisite galaxy images to date, showing the wonders of the universe in the thousands of colors – Passionategeekz

Passionategeekz On June 22, dozens of international scientists have drawn a panoramic image of the Jade Matsushi Galaxy (also known as NGC 253) in more than a thousand colors for the first time through the new MUSE spectrometer of the European Southern Observatory of Chile (ESO).

The relevant results were published in “Astronomy and Astrophysics” on June 18, revealing the fine structure of galaxies that have not been seen before.

The research team used a MUSE spectrometer to 50 hours to complete the epic image through 100 independent exposures, covering the core area of ​​the galaxy’s 90,000 light-year diameter.

“The galaxy of Jade is located at the golden observation location – close enough for us to analyze its internal structure and grand enough for us to see the entire galaxy,” said Enrico Congiu, the head of the ESO project and astronomer at the University of Chile.

During the analysis of the image, the team also accidentally discovered 500 brand new planetary nebula (gas dust ejected after the star dies). Fabian Scheuermann, a researcher at the University of Heidelberg in Germany, pointed out: “Outside the neighborhoods of the Milky Way, a single galaxy usually detects less than 100 cases.”

Passionategeekz reminds: Although these nebula are called “planetary shapes”, they have nothing to do with planets. Because of its nature, humans regard it as the key yardstick for measuring the scale of the universe. “They can pinpoint galaxy distances, which is the basis for all subsequent research,” said Adam Leroy, a researcher at Ohio State University in the United States.

After obtaining the first batch of results, scientists started new research on this basis: including exploring how high-temperature gases pass through the NGC 253 galaxy, changing the composition of matter and giving birth to new stars. “How these tiny processes affect galaxy systems thousands of times larger than them is still an unsolved mystery,” Kangjiwu concluded.
