NGC520 Galaxy (NGC520,Arp157)

I recently photographed this colliding galaxy just northeast of the Pisces Triplet. It is 100 million light-years away from Earth.
I was impressed by the thick blue arm stretching out to the southeast and the dust stretching from north to south on the eastern side, so I took this photo.
It's thought-provoking that while new stars are being born as a result of the collision, the galaxy is also coming to an end.

先日撮影した魚座のトリプレットの直ぐ北東にある衝突銀河。地球らの距離は1億光年。
南東に太く伸びる青い腕と東側を北から南に伸びる塵が印象的だったので撮影して見た。
衝突の影響で新しい星が生まれてる反面銀河としては終わりに向かっているというのは考えさせらてしまう。
