1.   X-ray telescopes can now detect virtually every type of astronomical object.

2.   And this was merely the precursor to several brutal encounters that are due to take place between spacecraft and astronomical objects over the next few years.

3.   It is also the first time a burst has been linked to a known astronomical object, like a galaxy.

4.   Scientists suspect that it could be a dim, failed star, or a type of astronomical object that has never been observed before.

5.   Scientists suspect that it could be a dim failed star or a type of astronomical object that has never been observed before.

6.   Several comprehensive sky surveys under way or just beginning are expected to discover many rare or even previously unknown types of astronomical objects and forces.

7.   Some astronomers suspect that the unusually huge planet may well be a type of astronomical object that has never been observed before.

8.   They can also shed light on types of astronomical objects only discovered in modern times.

9.   That wavelength is well-suited to seeing the most distant astronomical objects, as well as newborn stars and other things that tend to be hidden in dusty clouds.
