The wealth of information in this Hubble survey, including seeing stars of all sizes in one dense place, provides an extraordinary opportunity to study star formation. Our goal is to calculate the masses and ages...

In this bowl of stars we see the entire star formation history of Orion printed into the features of the nebula: arcs, blobs, pillars, and rings of dust that resemble cigar smoke. Each one tells...

Our goal is to calculate the masses and ages for these young stars, so that we can map their history and get a general scenario of the star formation in that region.
