If you happen to find yourself in the Southern Hemisphere with binoculars<\/a> and a good view of the night sky on a dark and clear summer night, you might just be able to spot the Sculptor galaxy<\/a>. And if your eyes were prisms that could separate light into the thousands of colors making it up, then congratulations: After hours of staring, you could have recreated the newest image<\/a> of one of the nearest neighbors to our Milky Way galaxy.<\/a><\/p>\n

This is not just another stunningly gorgeous picture of a nearby galaxy. Because it reveals the type of light coming from each location in the galaxy, this image of the Sculptor galaxy is a treasure trove of information that astronomers around the world cannot wait to pick apart.<\/p>\n

As an astronomy Ph.D. student<\/a> at Ohio State University, I (Rebecca) am one of the lucky people who gets to stare at this image for hours every day, alongside my adviser (Adam)<\/a>, discovering meaning behind the beauty everyone can appreciate.<\/p>\n

Creating the image<\/p>\n

The Sculptor galaxy lies 11 million light-years<\/a> from the Milky Way. This may sound unfathomably far, but it actually makes Sculptor one of the closest galaxies to Earth.<\/a><\/p>\n

For this reason, Sculptor has been the primary target for many observations. In 2022, an international team of scientists observed Sculptor with the Multi-Unit Spectroscopic Explorer<\/a>, MUSE, on the European Southern Observatory\u2019s Very Large Telescope<\/a> in Chile, and publicly released<\/a> the data this June.<\/p>\n

Most astronomical observations obtain<\/a> either an image of a single color of light \u2013 for example, red or blue \u2013 or a spectrum<\/a>, which splits the light coming from the whole galaxy into many different colors.<\/p>\n

MUSE, conveniently, does both, producing a spectrum<\/a> at every location it observes. One observation creates thousands of images in thousands of colors, each tracing the critical components that make up the galaxy: stars, dust and gas.<\/p>\n

It may look like only one picture, but this image of Sculptor is actually over 100 individual observations and 8 million individual spectra, painstakingly stitched together to reveal millions of stars all in one cohesive galaxy.<\/p>\n

The light associated with the stars in Sculptor is colored white, and gas made up of charged particles is colored red. The largest concentration of both is found in the spiral arms. At the very center of the galaxy is a nuclear starburst: a region of extreme star formation that is blowing material out of the galaxy<\/a>.<\/p>\n

There is even information in the absence of light. Dust obscures light emitted from behind it, creating a shadow effect called dust lanes<\/a>. Tracing these dust lanes reveals the cold, dense material that exists between stars<\/a>. Scientists believe this dark material is the fuel that will form the next generation of stars.<\/p>\n

There is a lot to look at in this image, but the subject of my work and what I find most interesting is the gas illuminated in red. In these star-forming regions<\/a>, young and massive stars excite the gas around them, which then glows with a specific color to reveal the chemical makeup and physical conditions of the gas.<\/p>\n

This image represents one of the first times that astronomers have obtained images of thousands of star-forming regions at this impressive level of detail. A component of our team\u2019s research uses the data from MUSE to understand how these regions are structured and how they interact with the surrounding galaxy.<\/p>\n

By meticulously piecing all of this information together, astronomers can use this image to learn more about the formation and evolution of stars across the universe.<\/p>\n
