By analyzing the data from various astronomical surveys, astronomers have investigated an old globular cluster known as NGC 288. As a result, they detected multiple extended tidal tails associated with this cluster. The finding was reported in a paper published September 25 on the pre-print server a...
A tidal tail is a thin, elongated region of stars and interstellar gas that extends into space from a galaxy. Tidal tails occur as a result of galactic tide forces between interacting galaxies. [...] Tidal forces can eject a significant amount of a galaxy's gas into the tail; within the Antennae Galaxies, for example, nearly half of the observed gaseous matter is found within the tail structures.
