The James Webb space telescope recently captured an image of a nearby dwarf galaxy, showcasing the capabilities it brings to the table.
Space is infinitely bigger than you could possibly imagine. And, while the way that the universe expands is still a mystery to scientists, we continue to observe what we can of the universe to learn more about it. Now, scientists are hopeful that observations of a nearby dwarf galaxy could provide more insight into how galaxies form and evolve over time.
The galaxy in question is known as Wolf-Lundmark-Melotte , and it can be found just 3 million light-years away from Earth. While that might seem far, it’s a pretty short distance when thinking about how big space is. WLM is a dwarf galaxy that has yet to interact with the Milky Way a lot, making it one of the best options around us to study in this capacity.
WLM is also interesting because it is made up of compounds more similar to galaxies of the early universe, something that thecould possibly investigate further. The system is unenriched, NASA says, and is poor in elements that are heavier than helium and hydrogen. That’s because most of those elements are expelled from the galaxy during supernovas.
