The journal publishes original papers and review articles on cosmic prebiotic chemistry, planetary evolution, the search for planetary systems and habitable zones, origins, evolution and distribution of life, experimental simulation of extraterrestrial environments, life detection in our solar system and beyond, human expansion, ecosystems beyond Earth, intelligent life and societal aspects of astrobiology, .
杂志刊载文章内容涉及宇宙前生命化学，行星演化，行星系统和可居住地的探索，生命起源，进化和分布，地球外环境的实验模拟，太阳系及以外生命探索，人类扩张，地球外生态系统，智能生命和太空生物学的社会方面。
Many astronomers were convinced that they were witnessing the end of cosmic history and that the future held nothing but the relentless expansion of a becalmed and senescent universe.
许多天文学家因此深信他们正目击宇宙历史的终结，宇宙的未来仅存无休止的膨胀，与年华老去后的凋蔽和寂静。
The simplest candidate of dark energy is the cosmological constant, which can explain the present cosmic accelerating expansion but at the same time it also leaves some theoretical problems unresolved.
暗能量最简单的候选者是宇宙常数，它虽然很好的解释了今天的宇宙加速膨胀但同时也存在一些需要解决的理论问题。
More than any other scientific problem the cosmic-expansion conundrum presents scientists with an existential quandary.
宇宙膨胀之谜给科学家们提供了一个比所有其它科学问题更大的存在难题。
These supernovae, called Type1a, serve as cosmic mile markers to measure expansion of the universe because they can be seen at large distances, and they follow a reliable pattern of brightness.
这类名为Ia型的超新星爆发由于可以在很远的距离上被观测到，并且亮度遵循可靠的模式，它们被当成测量宇宙膨胀的里程计。
If the universe is dense enough, gravitation can overcome the expansion and pull it back until it ultimately collapses. Cosmic rays are coming onto the planet so that a change is being broadcasted and a reordering is taking place inside the body.
如宇宙的密度足够大，引力就能够克服膨胀，并把宇宙拉回来，直到它最后发生坍缩。宇宙射线正来到地球上以便传送改变而重组内在身体的发生。
In order to explain the present cosmic accelerating expansion some physicists think that the observed acceleration is a signal of breakdown of our understanding of the laws of gravitation and propose to modify the Einstein's gravity theory.
观测结果验证了我们已经建立了的标准宇宙模型的同时，也给我们提出了新的挑战。1998年物理学家利用超新星来测量宇宙放慢的速率却意外的发现我们的宇宙正在做加速膨胀，此后大量的观测数据验证了这一结果，这一新的发现导致了宇宙学成为近几年物理学中最热门的学科之一。
