the η carina nebula is also called Callina nebula, keyhole nebula, carina nebula, or NGC3372. It is a huge nebula in the arm of the Milky Way Sagittarius, which is 9 light years away from us. It is located in the carina and contains several O-stars. The carina nebula is a huge bright nebula surrounded by η star, one of the largest and brightest stars in the Milky Way. Although it is far away from us, the central region of the nebula is still bright enough for the naked eye to see (although it is better to observe at the equator and the southern hemisphere).
deep space object NGC3372 carina has a big nebula NGC? 3372 (also known as "Carina Nebula"), whose appearance has been changing for a long time, is home to many massive stars. The most active celestial body in the nebula is "Haishan Erxing", that is, Carina η star, which briefly became one of the brightest stars in the whole day in the 193s, and then immediately dimmed. In NGC? The keyhole nebula can be found in the middle and lower part of 3372. There are several very massive stars in it, which makes its appearance change all the time. NGC3372 is about 7 light-years away and about 3 light-years in size.
Henize3_41 is about 1, light years away from us, and it is the narrowest known planetary nebula. For a spherical star, it is strange to produce a nebula of this shape, and some scientists think it is strange. Its long and narrow shape may be the clue to solve the mystery of the outer material ejection mechanism in the late stage of the star. After thousands of years, the nebula will dissipate, leaving only a white dwarf.
NGC2516NGC2516 or Diamond Cluster is an open cluster discovered by Nicola Louis Llakaj in 1751-52 in the southern constellation Carina. Because these stars have high definition, they are called diamond clusters. The cluster itself can be seen with the naked eye in the dark night sky, but the effect will be better with binoculars. The diamond cluster contains two beautiful fifth-order red giant stars and three pairs of binary stars, but at least a small telescope is needed to distinguish these binary stars. NGC2516 and Mamajek2, a cluster recently discovered near Ophiuchus, have similar age and metal content. Recently, E.Jilinksi and his collaborators presented dynamic evidence that both star groups were formed through the same star generation process 135 million years ago.
ic262c262, also known as Pleiades or Theta cluster in Carina, is an open cluster located in Carina. It was first discovered by French astronomer Llakaj in 1751. This cluster is about 479 light years away from the earth and can be seen by the naked eye.
