Hubble captures ancient star cluster that might be an interstellar hitchhiker

The Hubble Space Telescope has captured a stunning image of Messier 30 (M30), a globular cluster located about 27,500 light-years away in the constellation Capricornus. This dense, spherical collection of tens of thousands of stars acts as a cosmic time capsule, with some stars nearly as old as the 13.8-billion-year-old universe itself.

The ancient stars in M30 preserve chemical signatures from their formation era, offering astronomers clues about the Milky Way's early history. Intriguingly, M30's orbit moves opposite to our galaxy's rotation, suggesting it may not have originated here but was instead captured by the Milky Way long ago, making it a potential stellar interloper with a mysterious past.
