In the News: Awesome video of M8 taken with shots from the ACS on Hubble:
Breaking waves in the stellar lagoon (w/ Video)
Quote:
In recent years astronomers probing the secrets of the Lagoon Nebula have found the first unambiguous proof that star formation by accretion of matter from the gas cloud is ongoing in this region.
Young stars that are still surrounded by an accretion disc occasionally shoot out long tendrils of matter from their poles. Several examples of these jets, known as Herbig-Haro objects, have been found in this nebula in the last five years, providing strong support for astronomers' theories about star formation in such hydrogen-rich regions.
…
The wispy tendrils and beach-like features of the nebula are not caused by the ebb and flow of tides, but rather by ultraviolet radiation's ability to erode and disperse the gas and dust into the distinctive shapes that we see.

Very cool images. The boys in the "Deep Space" Forum have done a couple of Lagoon shots lately … for them :

The exposure times through each filter are 1560 s, 1600 s and 400 s respectively. The field of view is about 3.3 by 1.7 arcminutes.
