Explanation: How did a star create the Helix nebula? The shapes of planetary nebula like the Helix are important because they likely hold clues to how stars like the Sun end their lives. Observations by the orbiting Hubble Space Telescope and the 4-meter Blanco Telescope in Chile, however, have shown the Helix is not really a simple helix. Rather, it incorporates two nearly perpendicular disks as well as arcs, shocks, and even features not well understood. Even so, many strikingly geometric symmetries remain. How a single Sun-like star created such beautiful yet geometric complexity is a topic of research. The Helix Nebula is the nearest planetary nebula to Earth, lies only about 700 light years away toward the constellation of Aquarius, and spans about 3 light-years.

Looks to me like the Giant Eyeball In Space Lookin' Right At Me nebula.

Not enough pretty stuff in space that they have to post a rerun?
Yeah, it's an unusually beautiful rerun, but that's why everybody
remembers seeing it the first time.
Didn't someone say that it looks like the "Eye of God?"
Anyway, no fault of yours that they're running out of pretty
pictures from space, and it really is worth seeing again.
And spanning "only" three light years, it's also a cute little thing.
</just kidding you sweetie>

Helix? I am holding out for the Rush Nebula.

My recent image of the Helix, not exactly Hubble quality of course but it's a start.
Yeah, I don't know why they feel the need to do reruns, there's no shortage of new images from Hubble, some quite beautiful. I don't have the time to process them at the pace of one a day, but I do try to document a handful from the past month.
