The jug-like structure is a rare and short-lived double-lobed planetary nebula.
HR3126, which at just 50 million years old, is considerably younger than the 4.6-billion-year-old sun. HR3126 reached its red giant phase considerably more rapidly than the sun because the fact it is 5 times the mass of our star, which means it burned through its hydrogen much more rapidly than the sun does. The dying red dwarf star continues to expel gas and causes the material that surrounds it, which can take a variety of shapes, to glow brightly.
Beyond its aesthetic value, this double-lobed planetary nebula is of great value to scientists studying stellar evolution. That is because this particular end-of-life phase of red giant stars is brief, and thethat form around them are short-lived, lasting just around 20,000 years, and are thus rarely sighted.
The somewhat rare double-lobed or bipolar structures like that of the planetary nebula illuminated by HR3126 are believed to be the result of interactions between a red giant star and a stellar companion. Previous observations of IC 2220 have failed to turn up a companion star by HR3126, however. This absence suggests to astronomers that the companion star that once helped shape the hourglass-like form of IC 2220 has now been shredded, with its material now dispersed in the nebula.
