1.   Although astronomers expected the so-called Gunn-Peterson effect to be easily detectable, it did not show up in decades of searching until now.

2.   Astronomers expected to see the nearer supernovas expanding more slowly than the earlier, more distant ones.

3.   Astronomers expect no such stability on Neptune.

4.   Astronomers expect the findings to help refine models of galaxy formation and evolution through time.

5.   Some astronomers were expecting a big storm over Asia two years ago, but it turned out to be a minor display.

6.   The investigation, using the Earth-orbiting Hubble Space Telescope, was keyed to look for sodium, a readily detectable element that astronomers expected to be present.

7.   With this dazzling array of powerful new instruments, astronomers are expecting a wealth of data and discoveries unlike anything the field has seen before.

8.   Astronomers expect to release the full set of data over the next five years.

9.   Astronomers had expected the signal to brighten as a shock generated by the burst moved through a cloud of dense gas.

10.   Crisp said initial calculations from spectroanalysis of the clouds -- which involves identifying elements from the light they reflect -- suggested there was less water than astronomers had expected.
