Starship Asterisk*

NEW TYPE OF NEBULA DISCOVERED: The Heart of Hydra, ultra deep 360 hours For the first time, amateurs and scientists have succeeded in detecting a fully developed envelope of a so-called "common envelope" system, by which is meant the phase of the common envelope of a binary star system. ....

Wow you worked it out! It must be in the top 10 largest known PN! It must be really difficult to obtain spectra for something so faint. A really good idea is photographing blue stars to see if there is a faint nebula around them. Maybe 10-20 amateurs in the world could combine together for such a p...

This is an amazing and wonderful discovery! I think a few professional astronomers have predicted the existence of really large superfaint planetary nebulae, which are apparently really difficult to discover by professionals. If you know the distance of it, what could the size in light years be? It...

Fascinating! There is a tiny very blue star off-center inside the nebula, to the left. Could that be a PN central star, which is ionizing a planetary nebula? Ann Hi Ann, that' right! This star fulfills all requirements to be the central white dwarf. We could determine the following relevant data: -...
