Local Group Trend 2026

In the vast cosmic expanse, our Milky Way resides within a gravitationally bound collection of over 80 galaxies known as the Local Group. This galactic cluster, spanning roughly 10 million light-years, includes the Andromeda Galaxy and the Triangulum Galaxy. Astronomers study this region to understand galaxy evolution and dark matter, while science educators use it to illustrate large-scale universal structures. Ultimately, anyone observing the night sky benefits from defining our immediate cosmic neighborhood.
