A team of scientists has discovered a massive galaxy with little to no dark matter, challenging our current understanding of how the universe works. The galaxy, called NGC 1277, is located about 240 million light-years from Earth in the constellation Perseus. It is several times more massive than the Milky Way, but it contains only a fraction of the dark matter that is thought to be present in other galaxies of its size.

Dark matter is a mysterious substance that makes up about 85% of the matter in the universe. It cannot be seen directly, but its presence is inferred from its gravitational effects on visible matter. The discovery of a massive galaxy with little to no dark matter suggests that our understanding of dark matter may be incomplete.

"This is a very puzzling galaxy," said Sébastien Comerón, a researcher at the Instituto de Astrofísica de Canarias in Spain who led the study. "It doesn't fit in with our current models of how galaxies form and evolve."

One possible explanation for the lack of dark matter in NGC 1277 is that it was formed in a different way than other galaxies. The galaxy is located in a cluster of galaxies, and it is possible that it was stripped of its dark matter by the gravitational forces of its neighbors. Another possibility is that NGC 1277 is simply a very rare galaxy that does not contain any dark matter.

The discovery of NGC 1277 is a reminder that we still have much to learn about the universe. The galaxy challenges our current understanding of dark matter, and it will be interesting to see what new insights scientists can gain from further study.
