The Icy Blue Wings of Hen 2-437

A wintery bipolar planetary nebula

In this cosmic snapshot, the spectacularly symmetrical wings of Hen 2-437 show up in a magnificent icy blue hue. Hen 2-437 is a planetary nebula, one of around 3000 such objects known to reside within the Milky Way. Located within the faint northern constellation of Vulpecula (The Fox), Hen 2-437 was first identified in 1946 by Rudolph Minkowski, who later also discovered the famous and equally beautiful M2-9 (otherwise known as the Twin Jet Nebula). Hen 2-437 was added to a catalogue of planetary nebula over two decades later by astronomer and NASA astronaut Karl Gordon Henize. Planetary nebulae such as Hen 2-437 form when an aging low-mass star — such as the Sun — reaches the final stages of life. The star swells to become a red giant, before casting off its gaseous outer layers into space. The star itself then slowly shrinks to form a white dwarf, while the expelled gas is slowly compressed and pushed outwards by stellar winds. As shown by its remarkably beautiful appearance, Hen 2-437 is a bipolar nebula — the material ejected by the dying star has streamed out into space to create the two icy blue lobes pictured here.

Space news (March 09, 2016) – deep within the faint northern constellation Vulpecula (The Fox) –

Just one of over 3,000 spectacular planetary nebula astronomers have detected hidden within the Milky Way, the stunningly symmetrical icy blue wings of Hen 2-437 float upon the stars of Vulpecula in the Hubble image above. 

Just an icy blue cosmic moth adrift upon a sea of stars, Hen 2-437 is a bipolar nebula similar to hourglass shaped PN Hb 12 (Hubble 12) and the stunning M2-9 (The Twin Jet Nebula).

An example of a sun-like star in the final stages of its life cycle, material ejected by the dying star streamed outward into space to create the two icy blue wings of Hen 2-427 seen here. 

Sol will one day, billions of years in the future, swell to become a red giant and then expel its gaseous outer layers into space. Shrinking down to form a white dwarf, while ejected material is slowly compressed and pushed outward by stellar winds. The cast off gas streams outward into space to form the two icy blue lobes of Hen 2-437.
