Description

Sh2-240, SNR G180.0-01.7 or Simeis 147, is a supernova remnant (SNR), between the constellations Auriga and Taurus. Sh2 240 is large with a diameter of approximately 3 degrees, (6)full moons, with an almost spherical shell and filamentary structure of very low brightness.

At the core of the super nove is a rapidly spinning neutron star known as pulsar PSR J0538+2817. The Super Nova Remnant is approximately 3000 light-years distant with an age of about 40,000 years.

The large nebula on the left is Du 77. The Du catalogue is an obscure collection of 81 emission nebulae published in 1976 .

The small nebula below the SNR is Sh2-242
