New Hubble telescope image of the hybrid galaxy UGC 12591

UGC 12591 - This giant hybrid galaxy is located 400 million light-years from Earth and is one of the largest known galaxies in the universe.

Galaxy hybrid UGC 12591.

UGC 12591 is a hybrid galaxy, combining the characteristics of both pea-shaped galaxies and spiral galaxies. This galaxy is four times bigger than the Milky Way galaxy. The spiral of this galaxy rotates at a very fast speed, exceeding 1 million miles per hour.

Located about 400 million light-years from Earth, UGC 12591 is part of the Perseus-Pisces galaxy cluster , one of the largest structures known to man in the universe - hundreds of millions of light-years across.

Cosmologists are studying UGC 12591 to determine how it is made and developed. The researchers wanted to know if it was self-developed or the result of a giant collision between galaxies.
