从我们在银河系的有利位置，我们正面看到了NGC 3344。这个巨大而美丽的螺旋星系直径近4万光年，距离我们只有2000万光年，位于小狮子座。这张由哈勃太空望远镜拍摄的多色NGC 3344特写照片包含了从近红外到紫外波长的惊人细节。这个框架在螺旋的中心区域延伸了大约15000光年。从核心向外看，星系的颜色从中心老恒星发出的黄光变为年轻的蓝色星团和沿着松散、碎片化的旋臂形成的红色恒星区域。当然，这颗明亮的尖状恒星位于NGC 3344的前方，位于我们银河系的内部。APOD满30岁了！： 6月11日（星期三）晚上7点在安克雷奇举行免费公开讲座

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
