National Geographic: "Blue Blobs" in Space Are Odd Stars (http://news.nationalgeographic.com/news/2008/01/080108-weird-stars.html)

Mysterious "blue blobs" about 12 million light-years away are actually clusters of orphan stars that formed in an unlikely part of the universe, new images released today reveal.

An analysis of archived high-resolution images from the Hubble Space Telescope then revealed that the blobs were clusters of mostly young stars.

Scientists were surprised by the find, because the clusters of bright, massive stars sit along a wispy bridge of gases connecting M82 to two other galaxies it collided with 200 million years ago.

This means that the stars are "in the middle of nowhere," lead study author Duilia de Mello of Catholic University told reporters today at the annual meeting of the American Astronomical Society in Austin, Texas.

A lot more information here on the hubble site (http://hubblesite.org/newscenter/archive/releases/2008/02/) (with tabs for pictures, facts, etc)

I thought it sounded somewhat familiar to this one on the MW Ancestor (http://www.bautforum.com/astronomy/68890-ancestors-galaxies-like-milky-way.html).
Something that I never realized, is that these studies are done long after the observations and data are collected from a general set of observations that are not specifically looking for anything, or from anyone in particular.
