- Astronomers have at last identified what’s believed to be the edge of the Milky Way galaxy.
- A team of astronomers from England used that farthest point to determine that the diameter of the Milky Way is 1.9 million light-years, plus or minus 0.4 million light-years.
- It’s a scientific breakthrough that holds the potential to unlock more discoveries and insights about the galaxy that encompasses Earth, such as where and how many galaxies there are that surround the Milky Way.

Astronomers from Durham University in England have made an exciting discovery about the galaxy that includes Earth — specifically, they’ve finally found its far edge.
Using nearby galaxies as a guide, astrophysicist Alis Deason and her colleagues have determined the exact diameter of the Milky Way to be 1.9 million light-years (with a margin of error of 0.4 million light-years). That’s according to a paper from the team, posted at arXiv.org, which is an open-access archive of tens of thousands of articles from academics and scientists. And this work is important, for reasons that include the future additional discoveries it will help astronomers make.
