Facing NGC 3344

Explanation: 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.

正向星系NGC 3344
影像提供: ESA/Hubble & NASA
说明: 从我们所在的银河系看出去，NGC 3344以正面对着我们。这个宽度将近40,000光年的庞大美丽螺旋星系，位在小熊座方向，与我们的距离只有2千万光年。这幅哈勃太空望远镜的多波段NGC 3344特写影像，拍摄的波段包括近红外光到紫外光，而视野则涵盖这个螺旋星系中心约15,000光年宽的区域。从星系核心往外，这个星系的色彩渐次从核心区年老恒星的晕黄，转换成散布于松散、支离破碎螺旋臂上的泛蓝年轻星团和泛红恒星形成区。想当然耳，位于NGC 3344前方的带芒亮星，是近在我们银河内的恒星。
