Weekly Science Update

An infrared image of the star-forming cloud L1448. Astronomers have shown that self-gravity plays a key role in this source across large scales. The contours show the intensity of carbon monoxide emission. Other notation: numbered dots -- the locations of dense cores likely to produce future stars; asterisks -- the current young stars; circles -- regions where stars are almost but not yet born.
