| Herbig-Haro objects, Bok globules--Ay Carina! | Sep 10, 2011 2:44 AM PDT | url |

Added 1 new A* page:Yesterday I posted a really big picture of the awesome Carina Nebula. That was about as much bandwidth as I thought I should leech from you for one day, but there's plenty more to be seen of the nebula! So today let's zoom in on some pretty spots with the help of Hubblesite's gallery:
A closer (and I *think* true color; the false color version is here) view of the intricate peaks of gas in the star forming region visible in the lower right of the big image above; the gas is being sculpted both by jets from the new stars within, and by the intense radiation coming from super star system HD 93129 and its nearby cluster of bright stars, which are a ways up "above" the peaks (and not visible in this image):

^ The white dashes and arcs coming sideways off the "top" of the peaks in the upper left are caused by jets of material shooting out of the poles of newborn stars at the tips of those peaks as they pull in the material around them (and as that material is driven into them by radiation pressure from the surrounding big stars)--they are "Herbig-Haro" objects, like the ones I showed animations of a week or so ago.
Another neat star-forming region, with gas jetting out from the baby stars forming inside:

Zoomed way in (that's part of the Keyhole Nebula on the left) on a couple of the tiny, really dense gas clouds visible here and there in the main image; they're called by the unflattering name of Bok globules:

Here we have a pillar of gas and dust sculpted out of and cut off from its main cloud by the intense radiation pressure of the nebula's stars, and, finally getting its due, on the right, hypergiant + supergiant (superhypergiant? hypersupergiant?) binary star HD 93129, with a particularly tiny and eerie Bok globule next to it:

That's one bandwidth-heavy nebula! ;)
