Using the Sloan Digital
Sky Survey, the researchers found that the torrent of stars, which is supposed
to symbolize the remains of ancient star clusters, slowly absorbed with you our
own Milky Way galaxy.
A team of astronomers
from Yale University led by Ana Bonaca, masters and lead author of the new
study, had previously noted that the Milky Way has a tendency to absorb dwarf
galaxies,
which leads to its gradual growth. But this time, our galaxy, it
seems, did not have dinner, but only lightly bites: a stream of stars,
designated by scientists as the flow of the Triangle is actually the remains of
a single star cluster, rather than an entire galaxy.
It is believed that
galaxies formed gradually, through the merger of smaller galaxies or individual
star clusters. These processes may be key to the growth of galaxies like our
own Milky Way, scientists say.
The study will appear
in the journal The Astrophysical Journal Letters.
