Explanation:
This beautiful telescopic skyscape features spiral galaxy NGC 981. The island universe is about 50,000 light-years across and lies some 60 million light-years away toward the constellation Aries. An artistic presentation, the image shows spiky foreground stars in our own Milky Way Galaxy and convoluted dust clouds that hang above our galactic plane, dimly reflecting starlight. It also captures NGC 981 in a cosmic moment important to astrophysicists on planet Earth. Light from supernova SN2009js, absent in previous images, is indicated by the two lines just below and left of the galaxy's center. The supernova itself is the death explosion of a massive star within the plane of galaxy NGC 981. It was just discovered in October by supernova search teams in Japan and the US.

NGC981的艺术与科学

说明：
这张美丽的望远镜影像突出了旋涡星系NGC981  。这个岛宇宙大约有5万光年宽，位于白羊座内，距离我们约6,000万光年远。上面的影像是一张艺术家的印象画，显示的是我们银河系内针芒似的前景恒星，旋转的尘埃云悬挂在我们银河系盘面上，昏暗地反射出星光。影像在这一宇宙中的瞬间里还捕捉到了NGC981，这对于地球上的天体物理学家来说很重要。从超新星遗迹SN2009js发出的光，没有出现在先前的影像中，该超新星被两条直线标出，就位于星系中央的左下方。超新星是一颗位于NGC981盘面上的大质量恒星死亡爆炸留下的。这是由在日本和美国的超新星搜索小组十月份发现。

确实很漂亮！

学习了，图像相当精美！
