Huge waves are sculpted in this two-lobed nebula called the Red Spider Nebula, located some 3,000 light-years away in the constellation of Sagittarius. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion kilometers (62.4 billion miles) high. The waves are caused by supersonic shocks, formed when the local gas is compressed and heated in front of the rapidly expanding lobes. The atoms caught in the shock emit the spectacular radiation seen in this image.

NASA : A Hubble Cosmic Couple .- Una pareja cósmica vista por el Telescopio Hubble

Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido información de la Agencia Espacial NASA, sobre: Aquí vemos el espectacular maridaje cósmica de la Gallina estrellas 2-427 - más conocido como WR 124 - y la M1-67 nebulosa que lo rodea. Ambos objetos, capturado aquí por la NASA / ESA Hubble Space Telescope se encuentran en la constelación de Sagitario y se encuentran 15.000 años-luz de distancia.

La gallina estrellas 2-427 brilla en el centro mismo de esta imagen explosiva y alrededor de las matas calientes de gas circundante que están siendo expulsados hacia el espacio a más de 93.210 millas (150.000 km) por hora.

Hen 2-427 es una estrella Wolf-Rayet, llamado así por los astrónomos Charles Wolf y Georges Rayet. Wolf-Rayet son estrellas súper calientes que se caracterizan por una eyección de masa feroz.

El M1-67 nebulosa se estima en no más de 10.000 años de edad - sólo un bebé en términos astronómicos - pero qué hermoso y magnífico espectáculo que hace.

Here we see the spectacular cosmic pairing of the star Hen 2-427 — more commonly known as WR 124 — and the nebula M1-67 which surrounds it. Both objects, captured here by the NASA/ESA Hubble Space Telescope are found in the constellation of Sagittarius and lie 15,000 light-years away.

The star Hen 2-427 shines brightly at the very center of this explosive image and around the hot clumps of surrounding gas that are being ejected into space at over 93,210 miles (150,000 km) per hour.

Hen 2-427 is a Wolf–Rayet star, named after the astronomers Charles Wolf and Georges Rayet. Wolf–Rayet are super-hot stars characterized by a fierce ejection of mass.

The nebula M1-67 is estimated to be no more than 10,000 years old — just a baby in astronomical terms — but what a beautiful and magnificent sight it makes.

Hubble Observes Glowing, Fiery Shells of Gas

It may look like something from "The Lord of the Rings," but this fiery swirl is actually a planetary nebula known as ESO 456-67. Set against a backdrop of bright stars, the rust-colored object lies in the constellation of Sagittarius (The Archer), in the southern sky.

In this image of ESO 456-67, it is possible to see the various layers of material expelled by the central star. Each appears in a different hue - red, orange, yellow, and green-tinted bands of gas are visible, with clear patches of space at the heart of the nebula. It is not fully understood how planetary nebulae form such a wide variety of shapes and structures; some appear to be spherical, some elliptical, others shoot material in waves from their polar regions, some look like hourglasses or figures of eight, and others resemble large, messy stellar explosions - to name but a few.
