NGC 2146 (also known as the Dusty Hand Galaxy[2]) is a barred spiral galaxy type SB(s)ab pec in the constellation Camelopardalis. The galaxy was discovered in 1876 by Friedrich August Theodor Winnecke.[3]
It has a diameter of 80,000 lyr.[3] The galaxy's most conspicuous feature is the dusty lanes of a spiral arm lying across the core of the galaxy as seen from Earth, the arm having been bent 45 degrees by a close encounter with a smaller galaxy possibly NGC 2146a about 0.8 billion years ago.[3] This close encounter is credited with the relatively high rates of star formation that qualify NGC 2146 as a starburst galaxy.[3]
It has been host to two known supernova events:
SN 2005V, a type Ib/c supernova discovered by LIRIS on 30 January 2005.[4][5]
SN 2018zd, a type II supernova (possibly type IIn[6] and maybe the first electron-capture supernova[7][8][9]), was discovered on 2 March 2018 by Koichi Itagaki.[10]

In 1980, Ken'ichi Nomoto of the University of Tokyo predicted a third type called an electron capture supernova. ... In an electron capture supernova, as the core runs out of fuel, gravity forces electrons in the core into their atomic nuclei, causing the star to collapse in on itself.
