The remarkably thin galaxy IC 2233 is featured in this image from the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab. IC 2233’s needle-thin profile is due to both its structure and its orientation towards Earth. The galaxy’s orientation — known to astronomers as inclination — is almost exactly side-on, making this one of the flattest galaxies known. The exposure of this particular image is deep and the entire field littered with galaxies of various types of inclinations. As well as lying flat from our point of view, IC 2233 also lacks the prominent bulge that fattens the profile of spiral galaxies such as Andromeda and the Milky Way. The wafer-thin profile of this celestial needle has been fascinating observers for nearly 150 years — IC 2233 was first discovered in 1874 by the Welsh amateur astronomer Isaac Roberts, one of the pioneers of astrophotography.

This image shows the planetary nebula Sh2-42 in the constellation Sagittarius, and was captured by using the SMARTS 0.9-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF’s NOIRLab. Despite the name, planetary nebulae have nothing to do with planets — they are spectacular funeral pyres formed by red giant stars at the end of their lives. As these giant stars expand and throw their outer gaseous layers into space, the hot exposed core of the star ionizes the surrounding material, causing it to glow in a range of vivid colours. As it reaches the end of its life, our own Sun is expected to form a planetary nebula — but not for another 5 billion years!

Discovered in the year 1836 by John Herschel, NGC 6902 is a beautiful spiral galaxy located more than 130 million light-years away in the constellation of Sagittarius, the Archer. This image was taken with MUSE, the Multi Unit Spectroscopic Explorer instrument attached to one of the four 8.2-metre telescopes that make up the VLT, and shows the galaxy from a unique perspective. A zoom in towards the galaxy’s centre, the image shows a nuclear ring where the orange glow of intense star formation is visible. Inside this ring lies a faint and small bar of stars. Researchers found that stars within it are distributed differently depending on their age, with younger stars aligned along the bar and older stars more dispersed. These locations of the young and old stars within the central bar of NGC 6902 confirm predictions made years earlier from simulations and models. This is the first time these predictions of galactic structure were confirmed with observations thanks to the incredible spatial resolution of the MUSE instrument.
