Object Information                                            Imaging Details

Simeis147 is a supernova remnant (SNR) in the constellation Taurus. It lies about 3000 light-years distant. It's close to the star Elnath. Also known as the Spaghetti Nebula, the SNR is thought to have a reapidly rotating neutron star in its core.

The red color is from hydrogen that has become excited by absorbing energy resulting in an electron moving into a higher orbital. When the electron drops back down to a lower energy state, a photon of light is emitted. Red is a dominant hydrogen emission color.

This object was imaged from my front yard in light-polluted Las Cruces, NM. The map shows the SNR to scale.
