Cobe is designed to see just the biggest structures, but astronomers would like to see much smaller hot spots as well, the seeds of local objects like clusters and superclusters of galaxies.
Astrophysicists working with ground-based detectors at the South Pole and balloon-borne instruments are closing in on such structures, and may report their findings soon.
The story dated back to one night in March, 1993, when mr.and mrs.shoemakers went to an observatory near San Diego, California to observe heavenly bodies till dawn.
Follow-up spectroscopic observations with the planned James Webb Space Telescope later in this decade will be needed to definitively confirm the object's distance.
We will also be able to map the solar system in much greater detail than was previously possible and to study the formation of the Milky Way galaxy through observation at an unprecedented sensitivity.

8. 原理上,我们可以通过观测所谓的标准烛光(一种天体,它的绝对光度是相同的)来追溯宇宙内的历史。
In principle, one can trace that history back in cosmic time by observing a so-called standard candle, a class of astronomical object whose intrinsic luminosity is uniform.

14. 这些照片都是在太阳动力学观测站上拍摄到的,它目前是研究太阳这个天体中,最先进的航天器。
The pictures were taken by the Solar Dynamics Observatory (SDO), which is the most advanced spacecraft ever designed to study the Sun.
Even though asteroids of roughly that size fall to Earth a few times a year, the NEO Program telescopes often miss them because the survey is tuned to search for larger, more distant rocks.
What makes this one -- dubbed SN 1979C -- special is that it has been observed over the years with a series of orbiting x-ray telescopes, most lately the Chandra X-Ray Observatory.
Perhaps a massive unseen object is responsible for Sedna's mystifying orbit, its gravitational influence keeping Sedna fixed in that far-distant portion of space.
"I don't suspect we'll have completed the search for candidate objects until mid-2012, and then we may need up to a year of time to complete telescopic follow-up of those objects," said Kirkpatrick.

For the new study, appearing this week in the journal Nature, astrophysicist Reinabelle Reyes and colleagues looked at data gathered from more than 70, 000 bright, elliptical galaxies.

25. 当牛顿首先试图去了解天体的力学问题时,他已经知道了许多天文的观测及实验结果。
A number of astronomical observations and experimental result were known to Newton when he first tried to understand the dynamics of bodies.
Dr Nabila Aghanim, of the Institut d'Astrophysique Spatiale in Orsay, France, said: 'These observations will be used as bricks to build our understanding of the Universe.'
