Astronomers have made a discovery in a distant galaxy that could shed light on one of the universe's biggest mysteries. The finding was made using archived data from the Hubble Space Telescope. The discovery involves a faint stream of stars in a galaxy about 115 million light-years from Earth.

This stream is the remnant of a dense ball of stars being slowly torn apart by the galaxy's gravity. Further details about this discovery are available from the source, including information about the stream's formation and its significance in understanding the universe.
