你能在夜空中看到的最有趣的天体是什么？如果你住在北半球，带着一副好的双筒望远镜或小型望远镜，你可以在梅西耶星表中寻找非常受欢迎的天体。它们中的大多数，但不是全部，从地球的南半部也可以看到。这张特色图片显示了目录中所有110个天体的统一比例——相同的放大倍率。查尔斯·梅西耶在18世纪创建了这个目录。他对彗星很感兴趣，他的目录是在观察或寻找彗星时，在天空中已知的类似彗星的“要避免的物体”的列表。星表中的深空天体包括超新星遗迹（蟹状星云，M1）、其他星系（如仙女座星云，M31）、星云（如猎户座星云，M42，一个恒星形成区）和星团（如昴宿星团，M45，一个明亮的年轻疏散星团）。

What are some of the most interesting astronomical objects you can see in the night sky? Armed with a good pair of binoculars or a small telescope, if you live in the Northern Hemisphere, you can look for the very popular objects in the Messier Catalog. Most of them, but not all, are also visible from the southern half of the Earth. The featured image shows all 110 objects in the catalog at uniform scale -- the same magnification. Charles Messier created the catalog in the 18th century. He was interested in comets, and his catalog was a list of known comet-like "objects to avoid" in the sky when observing or hunting for comets. The deep sky objects in the catalog include a supernova remnant (the Crab Nebula, M1), other galaxies (such as Andromeda, M31), nebulae (e.g. the Orion Nebula, M42, a star-forming region) and stellar clusters (such as the Pleiades, M45, a bright young open cluster).
