Thousands of homes were burnt to the ground but authorities say the damage is far less than first feared. They're now working on producing a re-entry plan within two weeks. 加拿大艾伯塔省的巨大森林火灾发生近一周后，官员们首次进入麦克默里堡视察该地遭受的灾情。尽管几千座房屋被烧毁但政府表示情况没有最初担心的那么糟糕。政府将在两周之内做出让居民重返家园的计划。 NASA has discovered nearly 1300 new planets outside the Solar System. The exoplanets were found with the Kepler space telescope. NASA says the discovery increases the chance of finding at least one other planet like Earth that might support life. 美国国家航空航天局（NASA）在太阳系外又发现了近1300个新行星。这些外部行星是通过开普勒太空望远镜被发现的。NASA说此发现增加了我们在宇宙中找到至少一个像地球一样可能支持生命的宜居星球的机会。 |
