A | 《日报》全媒体记者 张宝程 地基垒完后，需要晾晒两天。 The prevailing theory among scientists is that around 4.5 billion years ago when the Earth was still forming and was covered in molten lava, it was struck by an object thought to be roughly the size of Mars known as Theia.,It is believed that Theia was destroyed in the process and Earth lost a significant portion of its mass. The gravitational pull of the remains of Earth then held debris from the event in its orbit which quickly, perhaps in less than 100 years, formed into the Moon.,Now, thanks to new research coming from the Swiss Federal Institute of Technology in Zurich, we have more evidence to back that up. Patrizia Will led a group of researchers in studying six lunar meteorites discovered in Antarctica in the early 2000s.,Science & TechBeat the Heat By Traveling to the Moon, Scientists Discover Pits That Stay 63 ℉ All Year27 July, 21:42 GMT,Inside she found small glass beads containing helium and neon that were formed during volcanic eruptions during the Moon’s early life. These gases are called noble gases because of their relatively low volatility. They are believed to have originated from Earth, inherited when the Moon was created in the aforementioned massive impact.,Scientists believe that because of the amount found in moon rocks and lunar meteorites, they must have come from Earth. The theory is that after the great collision, noble gases floated around Earth while superheated to thousands of degrees. The Moon formed at the same time and much of the noble gases settled in and on the Moon.,Had the gases come from elsewhere, like dust traveling on solar winds, scientists would expect there to be far less of it.,Despite their relative abundance, they're still fairly rare, and no study had been able to prove the existence of the gases in lunar meteorites before.,‘Best Physical Models Can’t Fit The Data’: Radio Bursts Detected in Space ‘Defy’ Existing Theories7 August, 14:45 GMT,Will was able to do so by weighing individual molecules to determine the makeup of chemical substances using an advanced mass spectrometer from the Noble Gas Laboratory at ETH Zurich.,Scientists are also trying to figure out how the noble gases got to Earth in the first place. There are two prevailing theories: that they were delivered here by comets and meteorites, or that they were present in a nebula cloud when the Sun was still young, and while Earth was forming, it pulled them in.,The plan is to look for other noble gases like krypton and xenon. If they are found on lunar meteorites and similar instances of the gases are found in other meteorites, then that would suggest that Earth likely got its noble gases from collisions early in its life. If not, that would lend more weight to the nebula theory.,The study’s authors say they found some evidence of krypton and xenon on the lunar meteorites, but more research will be required to confirm that.。
B | 9月13日，62岁的逯长久来到开工的新房处，满怀期待地说：“主体结构即将开始，找来的施工人员干活儿麻利，质量也不错，加上厕所、院墙等附属设施，估计一个多月后，新房就能竣工，心里挺敞亮的。” 施工人员正在砌墙。 逯长久住在建昌县杨树湾子乡蒙古营子村，他家的老房子有4间，灾情发生后受损严重，被定为需要重建的D级危房。
C | 9月8日，将破损的房子扒完之后开始垒地基。“我家共9口人，目前两口人住旁边的小棚子里，其余人住在亲戚家。政府补贴3.8万元，不足的从亲朋好友处筹集一些。
D | 大伙儿共同努力，争取早日住进新房里。” 该乡赵屯村73岁的董凤兰家盖新房的速度比逯长久家快一些，她家也属于需要重建的D级危房。
E | 因为惦记婆婆，她的儿媳妇与亲属一道，于9月3日就开始动工。
F | 截至9月13日，新房的整体架构已经完成，当天施工人员给墙壁抹灰、搭炕，9月15日吊棚。
G | 航拍施工人员正在给外墙抹灰。 “然后通通风，晾晒一下，估计过完中秋节就能入住。虽然前期受些损失，但前景挺乐观，非常感谢党委政府的补贴和帮扶。
H | ”董凤兰说。 据杨树湾子乡党委书记王保良介绍，经过权威统计，该乡共有需要重建的D级危房369户，政府补贴3.8万元，已经全部开工。“施工的方式有两种，一是自己找工程队建房，二是政府统筹与相关施工单位对接，估计10月底能全部入住。” 《日报》全媒体记者 杨兵 摄。
