2021年4月21日 · Messier 46 and Messier 47 are two young open clusters in the constellation Puppis. The twist? A small but bright planetary nebula can be seen "hiding" within M46! We drove to a Bortle 4 zone to image this pair of clusters and did our best while processing it to reveal the nebula as best as possible. How did it turn out? find out below!

2021年5月13日 · m46使用m26的炮塔，外形比较方正，并非“圆圆脑袋”。 M47使用T42坦克的炮塔，设计思路源于T37轻型坦克炮塔，优化了防弹外形，正面看比较尖瘦，炮塔两侧有光学测距仪镜头伸出，同样也并非“圆圆脑袋”。

東側（左）がm46(ngc2437)，西側（右）がm47(ngc2422)です。 M46はつぶのそろった微光星がぎっしり詰まった感じですが，M47の方は明るいまばらな星の集まりといった印象で，両者の見え方は対照的です。

m46和m47不知道，都长的像潘大头。 m48的首上装甲是铸造的有一点弧度，而且主炮是90mm的有制退器。 m60首上装甲是焊接的非常平整，可以加爆反，主炮是著名的l7 105线膛炮，有那个标志性的抽烟器。

2024年9月3日 · This NASA Hubble Space Telescope image showcases the planetary nebula NGC 2438, which is located in front of the open star cluster M46 (also known as NGC 2437). Most of the stars in this image are part of M46 and are roughly 5,400 light-years away, 2,400 light years behind the nebula.

2022年2月18日 · Right of center M47 is only 1,600 light-years away and NGC 2423 (top) is about 2500 light-years distant. Around 300 million years young M46 contains a few hundred stars in a region about 30 light-years across. Sharp eyes can spot a planetary nebula, NGC 2438, at about 11 o’clock against the M46 cluster stars.

m46とm47は、「とも座の二重星団」です。 冬の淡い天の川の中に肉眼でもぼんやり見える散開星団でそれぞれの距離 M46(NGC2438)、M47、冬の二重星団 －天の川のほとりで星空散歩－

This picture showcases a mesmerizing array of astronomical objects in a relatively small field, in the constellation of Puppis. The open clusters M46 and M47 are the main subjects, complementing the s...

2017年10月1日 · 该系列坦克的生产型车主要武器都采用1门M41式90mm坦克炮，俯仰范围为-9°～＋19°，炮管前端有一圆筒形抽气装置，炮口有导流反射式制退器，炮闩为立楔式，有电击式击发机构，炮管寿命为700发。

2012年4月3日 · Galactic or open star clusters are relatively young swarms of bright stars born together near the plane of our Milky Way Galaxy. Separated by about a degree on the sky, two nice examples are M46 (upper left) 5,400 light-years in the distance and M47 (lower right) only 1,600 light-years away toward the nautical constellation Puppis.
