Unravelling the web of a cosmic creeply-crawly
This new Hubble image is the best-ever
view of a cosmic creepy-crawly known as the Tarantula Nebula, a region
full of star clusters, glowing gas, and dark dust. Astronomers are
exploring and mapping this nebula as part of the Hubble Tarantula
Treasury Project, in a bid to try to understand its starry anatomy.
The Tarantula Nebula is located in one of our closest galactic
neighbours, the Large Magellanic Cloud. Hubble has released images of
this celestial spider several times before: in 2004 (heic0416), 2010 (heic1008), 2011 (heic1105) and 2012 (heic1206).
While these images show striking panoramic views of this turbulent
region, this new image gives us the deepest and most detailed view yet.Created using observations taken as part of the Hubble Tarantula Treasury Project (HTTP), this image is composed of near-infrared observations from both Hubble's Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). Due to the combination of infrared filters in this image a purple haze fills the frame, with deep red wisps of dust and bright stars scattered throughout.
This region is an example of an HII region — a large cloud of partially ionised hydrogen within which new stars are being born. Visible to the left of centre is a sparkling star cluster known as R136. It was initially identified as a star, but astronomers puzzled over how one single monstrous star could ionise a giant HII region. However, astronomers later realised it was actually a cluster of stars: a super star cluster.
R136 will eventually become a globular cluster: a spherical ball of old stars that orbits around the centre of its host galaxy. R136 is so massive that it contributes greatly to the Tarantula's brightness, emitting most of the energy that makes the nebula so visible.
The Hubble Tarantula Treasury Project (HTTP) is scanning and imaging many of the stars within the Tarantula, mapping out the locations and properties of the nebula's stellar inhabitants. These observations will help astronomers to view the nebula and piece together an understanding of the nebula's structure [1].
This new image is being released today, 9 January 2014, at the 223rd meeting of the American Astronomical Society in Washington, DC, USA.
Notes
[1] This image of 30 Doradus is also the focal point of an iBook on stellar evolution aimed at children with visual imparments. The book, called "Reach for the Stars: Touch, Look, Listen, Learn" is produced by Elena Sabbi — the lead researcher on this Hubble image — and her collaborators.
Hubble optical view of the Tarantula Nebula
This new Hubble image shows a cosmic creepy-crawly known as the Tarantula Nebula in visible, infrared and ultraviolet light. This region is full of star clusters, glowing gas, and thick dark dust.
Created using observations taken as part of the Hubble Tarantula Treasury Project (HTTP), this image was snapped using Hubble's Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). The Hubble Tarantula Treasury Project (HTTP) is scanning and imaging many of the many millions of stars within the Tarantula, mapping out the locations and properties of the nebula's stellar inhabitants. These observations will help astronomers to piece together an understanding of the nebula's skeleton, viewing its starry structure.

Wide-field view of the Tarantula Nebula and its surroundings (ground-based image)
This ground-based view of the Tarantula Nebula shows the nebula in
its entirety. It is the brightest region of star formation in the local
Universe. Hubble’s field of view covers just a tiny spot in the
upper-right quadrant of this image, though it reveals detail invisible
here, including a supernova remnant.
