11.   Properties of the quasar light should not only betray the presence of these hydrogen clouds but also reveal clues to star formation and galactic evolution.

12.   The array also will be able to study sun spots on other stars, witness the star formation and observe stars closely orbiting each other.

13.   The collapse in turn triggers reservoirs of gas to burst forth with new star formation.

14.   The first factor in the equation is the rate of star formation in the galaxy.

15.   The gamma rays would carry fingerprints of the gases through which they passed, yielding information about star formation.

16.   The hope is that it will be able to see light created back in the earliest days of star formation.

17.   The material in these disks, collapsing under the force of gravity, leads to star formation.

18.   The major impediment to incorporating this idea into a theory of star formation was the problem of the peculiar geometry of the jets.

19.   The key to star formation is gravity, says Hester.

20.   The smaller clumps of gas like a string of beads issuing from the region of star formation pose a particular puzzle for astronomers.
