NGC 17 NGC 17（NGC 34）是鲸鱼座的一个漩涡星系。NGC 17赤经为11分6.6秒，赤纬为-12°6'28″。在1886年首次被发现。
NGC 3918是一个在天球上位于半人马座的行星状星云，距离地球约4900光年。该星云昵称蓝行星状星云（Blue Planetary）或南方人（The Southerner）。发现历史 NGC 3918是位于南天球高纬度区域最明亮的行星状星云，可使用小型望远镜观测。该星云由英国天文学家约翰·赫歇尔发现于1834年3月。该星云在望远镜中所见到其接近...
NGC 2440就像只蝴蝶一样， 一颗白矮星也是“破茧而出”，开始另一段生命之旅。在这种比喻中，我们的太阳也像一只毛毛虫，而被抛出的气壳(茧壳)就是最美丽的蝴蝶了。这张照片里的“茧”是名为NGC 2440的行星状星云，它的内部有所知最炽热的白矮星之一。这张照片中心附近的白点， 就是这颗白矮星。我们的太阳...
