在遙遠的星系中，有一個名叫 NGC 3310 的旋渦星系，正舉辦著一場星星誕生的派對！大約一億年前，這個星系可能和一個小星系發生了碰撞，這次神奇的相遇讓 NGC 3310 照亮了星空，出現了大量的新星星！因為碰撞所產生的引力變化，使得氣體雲變得緊密，於是觸發了星星們的誕生派對。從雙子北望遠鏡拍攝的圖片可以看到，這個星系的美麗顏色中，粉紅色突出了氣體，而白色和藍色則表示了那些新出生的星星。有些星團還很年輕，這告訴我們，像 NGC 3310 這樣的星爆星系可能會持續活躍好一段時間！這個星系的直徑大約是 50,000 光年，距離我們大約 5,000 萬光年，在大熊座的方向，用小型望遠鏡就能看到哦！
原文:
The party is still going on in spiral galaxy NGC 3310. Roughly 100 million years ago, NGC 3310 likely collided with a smaller galaxy causing the large spiral galaxy to light up with a tremendous burst of star formation. The changing gravity during the collision created density waves that compressed existing clouds of gas and triggered the star-forming party. The featured image from the Gemini North Telescope shows the galaxy in great detail, color-coded so that pink highlights gas while white and blue highlight stars. Some of the star clusters in the galaxy are quite young, indicating that starburst galaxies may remain in star-burst mode for quite some time. NGC 3310 spans about 50,000 light years, lies about 50 million light years away, and is visible with a small telescope towards the constellation of Great Bear Ursa Major.
