It’s not every day we get to see a visual of the entire Sculptor Galaxy, located approximately 10-11 million light-years from Earth, in all its kaleidoscopic splendour. Astronomers have created a magnificent visual map of the spiral galaxy, also known as NGC 253, using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) located in Chile. In a new study published in Astronomy and Astrophysics, researchers used the Multi Unit Spectroscopic Explorer (MUSE) instrument on the telescope to valiantly observe the Sculptor Galaxy for 50 hours, merging 100 images into one dazzling map.
The Sculptor Galaxy map contains thousands of colors, a spectrum of which, the researchers explain, can help astronomers understand the system’s components (known as planetary nebulae) like specific regions of dust and gas and how they all move within the galaxy. With such detailed imagery, researchers can get up really close, even to observe individual stars. “We can zoom in to study individual regions where stars form at nearly the scale of individual stars, but we can also zoom out to study the galaxy as a whole,” said Kreckel in a statement.
Why is it important to identify these unique components? “Finding the planetary nebulae allows us to verify the distance to the galaxy — a critical piece of information on which the rest of the studies of the galaxy depend,” said Leroy in a statement.
