Star Burst Galaxy NGC2903 and NGC2905 (スターバースト銀河)

It is a galaxy that crosses the meridian before the LEO's neck, which is a pioneer of the spring galaxy season.
It is a galaxy that is bright enough even from Pattaya in the season of PM2.5 and high-rise thin clouds, so it is a wasteful size and brightness that Messier overlooked.The characteristic of this galaxy is that NGC2903 points to the entire galaxy, and NGC2905 points to the bright white nebula in the upper left of NGC2903.
It is said that it is extremely bright because a large number of stars have been born in this NGC2905.

春の銀河シーズンの先駆け的存在の獅子の鎌首より先に子午線を越えてくる銀河である。
このPM2.5と高層の薄雲の季節のPattayaからでも十分明るい銀河なのでMessierが見落としたにしてはもったいない大きさと明るさである。
この銀河の特徴はNGC2903が銀河全体を指していて、NGC2905はNGC2903の左上にある白く明るい星雲を指している。
このNGC2905の中では大量の星が生まれてきているため明るいのだそうだ。
