Variable Nebula: Astronomy’s Lost Targets
Over a hundred Years ago a young Edwin Hubble showed the world that NGC2261 (soon to become Hubble’s variable Nebula) was pulsating. Amazing but something even more amazing shoved these amazing objects out of the limelight and into a forgotten branch of astronomy that few have considered again until now. . .
(oh and the even more amazing thing was the discovery of galaxies)
Hubble’s Variable Nebula – Big Amateur Telescope
Although Hubble’s variable nebula isn’t kicking off the way we would hope, we can still see the changes in the ripples of light in this animation which is the BAT’s most recent attempt.
But what we really want to see are the dark shadows passing over the nebula, and when it does, our team at the Big Amateur Telescope will be ready!
This recent GIF was made using a 5 day averaging of the submitted stacks with contributions by @HatMandew @TheCyberBrick @SpaceKadet @SPACEVISION @hnau @poptart @AstroBob @relogge @T3kko @[SF.FS]elSchabei @malden and @MrCrazyPhysicist all from The Big Amateur Telescope on the astrobiscuit discord server! The animation was then expertly processed by @MrCrazyPhysicist.
Hubble Space telescope caught similar ripples coming from a much older Cepheid Variable Star called RS Puppis
Tom Polakis’s bagged a dark shadow passing across Hubble’s variable nebula 5 years ago from Pheonix Arizona.
