This intense radiation may destroy molecules that had previously been ejected by the star and that are bound up in the clumps or rings of material seen in the periphery of planetary nebulas.
About where the pinion feathers would attach you'll find NGC 6826, the Blinking Planetary Nebula. The Blinking Planetary is even smaller than the Cat's Eye, so you'll need some magnification here, but I include it because it's one of the best interactive objects in the night sky.
But, in the case of planetary nebula HuBi 1, the scientists observed some major changes.
A team of international astronomers, including Professor Albert Zijlstra from the School of Physics & Astronomy, predicts it will turn into a massive ring of luminous, interstellar gas and dust, known as a planetary nebula.
Well out of the fiery danger zone, situated between the pillars that hold the burning altar pot, is the planetary nebula NGC 6326 about 2.5 degrees south of alpha Arae.
Another brilliant planetary nebula is NGC 7662 in Andromeda, aka the Blue Snowball.
Planetary nebula like Mz 3 are formed when low- to middleweight stars, like our sun, turn into white dwarves near the end of their lives.
The Boomerang is a pre-planetary nebula, representing the stage in a star's life immediately preceding the planetary nebula phase, when the central star is not yet hot enough to emit sufficient ultraviolet radiation to produce the characteristic glow.
The small but bright planetary nebula NGC 7662 (Caldwell 22) is located roughly 14[degrees] east of the Andromeda Galaxy.
It's a classic planetary nebula, showing distinct red- and teal-colored regions corresponding to hydrogen-alpha and oxygen-III emissions, respectively.
Due to the hot core, the ejected ring shines brightly for almost ten thousand years, making the planetary nebula visible.
