Celestial Fireworks | NASA

Westerlund 2 Hubble image

The brilliant tapestry of young stars flaring to life resemble a glittering fireworks display in the 25th anniversary NASA Hubble Space Telescope image, released to commemorate a quarter century of exploring the solar system and beyond since its launch on April 24, 1990.
To capture this image, Hubble’s near-infrared Wide Field Camera 3 pierced through the dusty veil shrouding the stellar nursery, giving astronomers a clear view of the nebula and the dense concentration of stars in the central cluster. The cluster measures between 6 and 13 light-years across.
The giant star cluster is about 2 million years old and contains some of our galaxy’s hottest, brightest and most massive stars. Some of its heftiest stars unleash torrents of ultraviolet light and hurricane-force winds of charged particles etching into the enveloping hydrogen gas cloud.
The nebula reveals a fantasy landscape of pillars, ridges and valleys. The pillars, composed of dense gas and thought to be incubators for new stars, are a few light-years tall and point to the central star cluster. Other dense regions surround the pillars, including reddish-brown filaments of gas and dust.
The brilliant stars sculpt the gaseous terrain of the nebula and help create a successive generation of baby stars. When the stellar winds hit dense walls of gas, the shockwaves may spark a new torrent of star birth along the wall of the cavity. The red dots scattered throughout the landscape are a rich population of newly-forming stars still wrapped in their gas-and-dust cocoons. These tiny, faint stars are between 1 million and 2 million years old -- relatively young stars -- that have not yet ignited the hydrogen in their cores. The brilliant blue stars seen throughout the image are mostly foreground stars.
Because the cluster is very young -- in astronomical terms -- it has not had time to disperse its stars deep into interstellar space, providing astronomers with an opportunity to gather information on how the cluster formed by studying it within its star-birthing environment.
The image’s central region, which contains the star cluster, blends visible-light data taken by Hubble’s Advanced Camera for Surveys with near-infrared exposures taken by the Wide Field Camera 3. The surrounding region is composed of visible-light observations taken by the Advanced Camera for Surveys. Shades of red represent hydrogen and bluish-green hues are predominantly oxygen.
The Hubble Space Telescope is a project of international cooperation between NASA and ESA (European Space Agency). NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington.

Westerlund 2 Hubble image

el dispensador dice:
de los fuegos provienes,
de los fuegos has sido creado,
nacer es transitar un karma,
que se viene replicando...

de los fuegos eternos,
nace todo en el espacio,
expresándose diferente,
según la gracia que se haya dado...

debes tener en claro,
que el universo que no contemplas,
existe a pesar de lo dicho,
por cualquier ser humano,
y lo hace desde siempre,
porque las geometrías universales... no guardan ángulos...
ya que los triángulos,
son pobres perspectivas,
de los propios seres humanos,
que se asumen como propios mesías, 
profetas efímeros de tiempos escasos...

ve más allá...
hay más de un destino,
esperando.
AGOSTO 07, 2015.-
