NASA : Hubble Watches the Icy Blue Wings of Hen 2-437 .- Telescopio Hubble, atrapa alas heladas azules de la Gallina 2-437

Hola amigos: A VUELO DE UN QUINDE EL BLOG., En esta foto cósmica, las alas simétricas de forma espectacular Hen 2-437 se muestran en una magnífica tonalidad azul helado. Hen 2-437 es una nebulosa planetaria, uno de alrededor de 3.000 objetos tan conocidos para residir dentro de la Vía Láctea.

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 catalog 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.
