MWP1 (PK080-10.1) - Methuselah Nebula
MWP1 (named after its discoverers C. Motch, K. Werner and M. Pakull) is a 150,000 years old, faint bipolar planetary nebula of about 15 light-years across, located some 4,500 light-years away in the northern constellation of Cygnus (the Swan). It is expanding with a velocity of approximately 20 kilometres per second.
MWP1 is one of the oldest planetary nebulae known, and is therefore sometimes nicknamed the Methuselah Nebula. It is also one of the largest planetary nebulae known, and its progenitor star is one of the hottest stars known, so hot it is producing large amounts of X-rays.
ALV1 (Alves 1) is that smaller spherical PN below MWP1. It was discovered by Portuguese amateur astronomer Filipe Alves in 2009.
