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 Ursa Major.

📷 事件仍在螺旋星系 NGC 3310 進行中！約一億年前，NGC 3310 很可能與一個較小的星系相撞，導致這個大型螺旋星系爆發出驚人的恆星形成。碰撞期間改變的重力創造了密度波，壓縮現有的氣體雲，觸發了這場恆星形成的派對。來自雙子星北天文台的精美圖像展示了這個星系的細節，以顏色標示：粉紅色強調氣體，白色和藍色則突出恆星。星系中一些恆星團的年齡相當年輕，顯示出星暴星系可能會在星暴狀態下持續相當長的時間。NGC 3310 的直徑約為 50,000 光年，距離我們約 5,000 萬光年，並且在大熊座中可用小型望遠鏡觀察。
