Arcturus, the red star of Boötes, and Spica, the blue star of Virgo.

Both are famous stars that make up the Spring Triangle, Spring Diamond.

Arcturus, a red giant that runs out of hydrogen and shines red with helium, and Spica, which shines blue near the vernal equinox, are also called couple stars in Japan.

Arcturus is doing a proper motion toward Spica because he misses Spica, and it seems that he will be close to each other in tens of thousands of years.

I would like to take a picture of red and blue 1st magnitude stars nestling next to each other in 1 frame, but it's a shame because no human being has such a long life.

牛飼い座のα星の赤い星のArcturusと乙女座のα星の青い星のSpica。

共に春の大三角形、春のダイヤモンド及び春の大曲線を構成をする有名な恒星である。

水素を使い果たしヘリウムで赤く輝く赤色巨星のArcturusと秋分点の近くで青く輝くSpicaは日本では夫婦星とも呼ばれている。

ArcturusはSpicaが恋しいのかSpicaに向かって固有運動をしており数万年後には隣同士に寄り添うそうだ。

赤と青の1等星が隣同士で寄り添う姿を1 Frameで撮影したいが、そんな寿命が長い人類はいないので残念だな〜。
