Star Birth in the Trifid Nebula: This NASA Hubble
Space Telescope image of the Trifid Nebula reveals a stellar nursery
being torn apart by radiation from a nearby, massive star. The picture
also provides a peek at embryonic stars that are forming within
an ill-fated cloud of dust and gas, which is destined to be eaten
away by the glare from the massive neighbor. This stellar activity
is a beautiful example of how the life cycle of stars like our Sun
is intimately connected with their more powerful siblings. Courtesy:
