Cluster of 'otherworldly' objects appear in the middle of a galaxy containing Earth

ESA's Gaia Space Telescope and Canada-France-Hawaii Telescope have both recorded a strange line of stars, clearly not belonging to our galaxy.

Dubbed C-19, the newly discovered line of stars is the remnant of an ancient globular cluster , containing stars with extremely low metallicity, with heavy element concentrations up to 2,500 times lower than the Sun.

According to Sci-News, if visible to the naked eye, we will see C-19 spread across the night sky with the length of 30 full moons side by side. Its orbit is 20,000 light-years from the center of the galaxy containing the Earth, the Milky Way, and 90,000 light-years at the farthest.

Dr. Jonay González from the Institute of Astrophysics of Canarias (Spain), a member of the research team, said that based on the properties that are different from other stars in the Milky Way, the C-19 star line must have a source. from another galaxy.

After identifying C-19 through the data of the two aforementioned telescopes, scientists further investigated with the Gemini North Telescope and its GRACES instrument, helping to realize that C-19 is a remnant. of a globular cluster. The globular cluster originates from very early generations of stars, so C-19 is one of the living "fossils" from the dawn of the universe.

It was introduced into the Earth-containing galaxy in a violent collision, which resulted in its host galaxy being swallowed up by our massive Milky Way "monster".
