A gorgeous acrylic poster of the Dwarf Galaxy, it really makes you think how small we are in the bigger picture.

A portion of the dwarf galaxy Wolf–Lundmark–Melotte captured by the James Webb Space Telescope’s Near-Infrared Camera. The image demonstrates Webb’s remarkable ability to resolve faint stars outside the Milky Way. Color translation: 0.9-micron light is shown in blue, 1.5-micron in cyan, 2.5-micron in yellow, and 4.3-micron in red (filters F090W, F150W, F250M, and F430M).

Wolf–Lundmark–Melotte is a dwarf galaxy in our galactic neighborhood. It's fairly close to the Milky Way (only about 3 million light-years from Earth), but it's also relatively isolated. We think Wolf–Lundmark–Melotte hasn’t interacted with other systems, which makes it really nice for testing our theories of galaxy formation and evolution. Many of the other nearby galaxies are intertwined and entangled with the Milky Way, which makes them harder to study.

Another interesting and important thing about Wolf–Lundmark–Melotte is that its gas is similar to the gas that made up galaxies in the early universe. It’s fairly unenriched, chemically speaking. (That is, it’s poor in elements heavier than hydrogen and helium.)

This is because the galaxy has lost many of these elements through something we call galactic winds. Although Wolf–Lundmark–Melotte has been forming stars recently—throughout cosmic time, really—and those stars have been synthesizing new elements, some of the material gets expelled from the galaxy when the massive stars explode. Supernovae can be powerful and energetic enough to push material out of small, low-mass galaxies like Wolf–Lundmark–Melotte.

This makes Wolf–Lundmark–Melotte super interesting in that you can use it to study how stars form and evolve in small galaxies like those in the ancient universe.
