The Intergalactic Wanderer(ヤマネコ座の球状星団)NGC 2419

Too dark for watching by Mobile Phone.

Although it is a globular cluster in Lynx, its distance is said to be 300,000 light-years, and it is located farther than the Large Magellanic Cloud. It is a star cluster far away from our Milky Way galaxy, which is 100,000 light-years in diameter. Therefore, it was named because it was previously thought to be a cluster floating in outer space, but recent research has apparently had a gravitational connection with the Milky Way galaxy, and it has revolved around the Milky Way galaxy over 3 billion years. It is becoming clear.

ヤマネコ座にある球状星団であるが、その距離は30万光年と言われており、大マゼラン星雲より遠くに位置する。直径10万光年の我々の天の川銀河より遥か彼方にある星団である。よって以前は宇宙空間に浮かんでいる星団と思われていたため、この名前がつけられたが、最近の研究ではどうも天の川銀河と重力的結びつきがあり、天の川銀河を30億年かけて公転していることがわかってきている。
