New Evidence Supports Theory That the Moon was Once Part of Earth_我的网站

一 |     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.。    6·3 지방선거 투표용지 부족 사태 등을 수사하는 이태한 선거관리위원회 특별검사가 지난 24일 서울 서초구 특검 임시 사무실로 출근하며 취재진의 질문에 답하고 있다. / 사진=연합뉴스6·3 지방선거 투표용지 부족 사태 등을 수사하는 이태한 선거관리위원회 특별검사가 특별검사보 후보자 10명 선정을 끝내고 이재명 대통령에게 임명을 요청할 예정입니다.이 특검은 오늘(26일) 언론 공지를 통해 "어제 특검이 가지고 있던 명단과 대한변호사협회(변협)로부터 전달받은 명단을 종합해 후보군 10명을 선정했다"며 이같이 설명했습니다.이 특검은 "다만 특검보 후보들의 결격사유 등에 대한 확인 작업을 하는데 1∼2일 정도가 소요돼 그 이후 대통령실로 명단을 송부할 예정"이라고 했습니다.그러면서 "특검보 후보는 오직 실무능력 위주로 선정했고 준비기간 중이라도 특검보가 임명되면 곧바로 기록 검토 후 기초수사에 착수할 수 있도록 만전을 기하고 있다"고 덧붙였습니다.앞서 이 특검은 특검보 인선 기준에 대해 포렌식 능력과 수사 능력을 최우선으로 고려하고, 부수적으로 정치적 중립성과 객관성, 인품, 사회적 평가 등을 종합적으로 판단하겠다고 밝힌 바 있습니다.특검보는 특검의 지휘·감독에 따라 사건 수사와 공소 유지, 특별수사관 및 파견공무원에 대한 지휘·감독과 언론 공보 등을 담당하며 검사장급 대우를 받습니다.특검법에 따르면 대통령은 특검보 임명 요청일로부터 5일 안에 5명의 특검보를 임명해야 합니다.특검보 5명이 정해지면 다음 달 초부터 본격적인 수사에 착수할 것으로 전망됩니다.이 특검은 이번 주 중 검찰과 경찰로부터 파견 인력도 우선으로 받을 계획입니다. 전날 서울지방변호사회를 찾아 특별수사관 모집도 요청했습니다.검경 합동수사본부도 특검에 수사 기록을 이첩할 준비를 마무리한 것으로 전해졌습니다.이 특검은 서울 서초구 서초동 더베이스서초빌딩에 마련된 임시 사무실로 출근해 파견직원 인선 등 출범 준비 작업을 하고 있습니다.국회 국정조사특별위원회가 올림픽공원 개표소 현장검증에 특검의 참관을 요청한 상태라 관련 절차와 법률적 근거도 검토 중입니다.。
