Hi-diddly-ho, neighborino! 👋⁣ ⁣ Our neighbor in space, the immense Andromeda galaxy, is captured in this image taken by the Wide-field Infrared Survey Explorer (WISE). Located about 2.5 million light-years from our Sun, Andromeda is the closest large galaxy to our Milky Way galaxy.⁣ ⁣ This galactic mosaic is a four-color composite using all of WISE’s infrared detectors, where blue represents far-ultraviolet light, green represents mid-way ultraviolet light, and red is near-ultraviolet light. The galaxy's backbone of mature stars is visible in blue, while the yellow and red rings show dust heated by newborn, massive stars.⁣ ⁣ Both the Milky Way and Andromeda galaxies belong to our so-called Local Group, a collection of more than 50 galaxies, which is like our “galactic neighborhood”; however, most of the other galaxies are tiny dwarf systems.⁣ ⁣ Credit: NASA/JPL-Caltech/UCLA⁣ ⁣ #NASA #Space #Galaxies #Galaxy #Stars #Astrophotography #Andromeda #MilkyWay #Astronomy
