PGC 6240 [SEP] constellation
PGC 6240
PGC 6240, also known as AM 0139-655 or the White Rose Galaxy, is a very large and old galaxy in the southern constellation of Hydrus, about 345 million light years away from Earth.
Appearing like a white rose in the sky, the galaxy has foggy shells of stars that rotate around a luminous center with few shells lying close to it while others at a distance. Those distant from the center appear disconnected from the white rose.
The age of globular clusters in this galaxy is
. It was very likely to have been a faint comet. PGC 6240, known as the White Rose Galaxy, is a giant spiral galaxy surrounded by shells resembling rose petals, located around 345 million light years from the Solar System. Unusually, it has cohorts of globular clusters of three distinct ages suggesting bouts of post-starburst formation following a merger with another galaxy. The constellation also contains a spiral galaxy, NGC 1511, which lies edge on to observers on Earth and is readily viewed in amateur telescopes.
