面向 NGC 3344
Facing NGC 3344

發表日期:2025-06-08
從銀河系的有利位置,我們可以看到 NGC 3344 的正面。這個美麗的大螺旋星系直徑將近 4 萬光年,距離小獅子座僅 2 千萬光年。這張哈勃太空望遠鏡拍攝的 NGC 3344 多色特寫包含了從近紅外到紫外線波段的顯著細節。畫面延伸了大約 15000 光年,橫跨螺旋星系的中心區域。從核心向外,星系的顏色從中心老恆星的淡黃色光,變為年輕的藍色星團,以及沿著鬆散、支離破碎的旋臂形成的淡紅色恆星區。當然,在 NGC 3344 的前方,還有一些外表呈尖刺狀的明亮恆星,它們就位於我們的銀河系內。 APOD 30 週年慶典安克雷奇免費公開講座, 6 月 11 日星期三晚 7 點
原文:From our vantage point in the Milky Way Galaxy, we see NGC 3344 face-on. Nearly 40,000 light-years across, the big, beautiful spiral galaxy is located just 20 million light-years away in the constellation of Leo Minor. This multi-color Hubble Space Telescope close-up of NGC 3344 includes remarkable details from near infrared to ultraviolet wavelengths. The frame extends some 15,000 light-years across the spiral's central regions. From the core outward, the galaxy's colors change from the yellowish light of old stars in the center to young blue star clusters and reddish star forming regions along the loose, fragmented spiral arms. Of course, the bright stars with a spiky appearance are in front of NGC 3344 and lie well within our own Milky Way. APOD Turns 30!: Free Public Lecture in Anchorage on Wednesday, June 11 at 7 pm
