21.   One of the best things about the new planet discoveries is that an amateur astronomer had something to do with them.

22.   So far astronomers have had little time to assess the mountain of data their instruments are collecting.

23.   Such a scenario could also explain why astronomers have yet to find more than one planet around a single star.

24.   The aspiring astronomer had little time to prepare for the state bee because he was also getting ready for the Alamo Area Regional Science and Engineering Fair.

25.   The defining difference, he said, is presumably how they formed, and astronomers have no way yet to establish how the enormous mystery object originated.

26.   Unable to pierce this black veil, astronomers have had to content themselves with constructing, from physical principles, their own scenario for how a star takes shape.

27.   With bigger, more sensitive telescopes, astronomers may have to get used to new mysteries like this one.

28.   With them, astronomers had the means to look for primordial galaxies under the assumption that these galaxies might look pretty much like those near our Milky Way.

29.   But astronomers have to search mightily for supernovae, making the discovery of a supernova a dramatic event.

30.   If the power trouble worsened, astronomers would have to use only one scientific instrument at a time.
