上面的星系可能更上镜，但下面的星系更不寻常。上面的星系是NGC 3660，一个类似于我们银河系的螺旋星系，因为它有几个明亮的蓝色旋臂和一个由恒星、尘埃和气体组成的中央棒状星系。令人惊讶的是，在这张具有特色的深彩色图像中偶然捕捉到的是SN 2026cff，它是一颗超新星，就在中央条纹的右侧。更远的地方是底部的星系，非正式地称为burin星系，但正式的编目是LEDA 1000714。这个星系的中心看起来是一个古老的椭圆星系，但奇怪的是，它被两个而不是一个恒星环包围着。是什么创造了burin星系是一个谜，仍然是一个持续研究的主题，但它可能涉及一个或多个较小星系的吸积。

The upper galaxy might be more photogenic, but the lower galaxy is more unusual. The galaxy up top is NGC 3660, a spiral galaxy similar to our own Milky Way galaxy in that it has several bright blue spiral arms and a central bar of stars, dust, and gas. Captured by chance in the featured deep and colorful image, surprisingly, is SN 2026cff, a supernova found just to the right of the central bar. Farther in the distance is the bottom galaxy, known informally as Burçin’s galaxy, but formally cataloged as LEDA 1000714. The center of this galaxy appears to be an old elliptical galaxy, but it is strangely surrounded by not one but two rings of stars. What created Burçin's galaxy is a mystery and remains a continuing topic of research, but it likely involves the accretion of one or more smaller galaxies.
