Planetary nebula
Minkowski 2-42 , abbreviated M2-42 , is a planetary nebula that was discovered by Rudolph Minkowski in 1947.[ 2] light-years away from Earth in the Galactic bulge .[ 1] bipolar planetary nebula containing two jets of material emerging from both sides of its central star .[ 3] Fast Low-Ionization Emission Region (FLIER). [ 3]
The central star of M2-42 is classified as weak emission-line star ,[ 4] [ 5] Wolf-Rayet central stars of planetary nebula ([WN]).[ 3] [ 6]
