in the carbon dioxide that has been increasing in our atmosphere since the start of industrial times.Carbon dioxide on Venus has created a runaway greenhouse effect, but here on Earth — so far — the planet's living organisms have been struggling to maintain a balanced atmosphere that continues to support life. Scientists studying this phenomenon are worried that things are getting out of ...
지난 1992년 10월 8일 목요일은 지구를 위해 가장 열심히 일하고 충성스럽게 금성의 궤도를 순회하던 파이어니어 12호라는 종이 사라진 날이었다. 이 인 ... of what happens to our planet's surface. On Venus, We can detect what the surface is and was like, and how the strange Venusian atmosphere affects it.(C) 1992, Los Angeles Times ...
have atmospheres that are largely nitrogen. The giant planets have atmospheres that are mostly hydrogen. Mars and Venus have atmospheres that are mostly carbon dioxide.Next question : Where did the nitrogen come from? One possible answer arises from the internal structure of Titan. The central portions of Titan are rocky in nature, but around that rock is a thick layer of ice--diamond-hard ...
마젤란의 활동이 두드러지면서 '사랑의 여신'(Venus)인 금성이 점차 신비의 모습을 드러내고 있다.사진은 마젤란이 최근에 송신한 데이터를 기초로 해 미국항공우주국(NASA)에서 작성한 금성표면의 모습이다. 표면은 50℃가 넘는 고온에 기복이 매우 심한 모습을 하고 있는 것으로 드러났다.마젤란은 198 ...
천체일뿐만 아니라, 그 색깔이 푸르고 아름다워서 서양에서는 '사랑의 여신'인 비너스(Venus)라 불리고 있다.금성을 육안으로 보면 다른 별들과 같이 하나의 둥근 점으로 보이지만, 망원경으로 관측하면 달과 같이 위상(位相)을 가지고 있다. 이러한 사실은 1610년 갈릴레이가 망원경으로 금성을 처음 ...
miss. It was brighter than any object in the sky, other than the sun or moon. It wa two or three times brighter than Venus, the glorious evening star. It was so bright that it was visible in the daytime for 23 days, and at night for nearly two years before it faded away and disappeared - - at its brightest it actually cast a shadow.Yet no one in Europe saw it; or at least no European report ...
시스템을 연구, 구축하고 있으며, 일본에서는 과학기술청의 Mu 기계번역시스템과 NEC의 VENUS 기계번역시스템이 연구되고 있다. 인간이 컴퓨터를 도와준다(?)많은 사람들은 기계번역 연구가 수행되면 번역가들은 직업을 잃을 것이라고 걱정을 한다. 그러나 컴퓨터가 사람과 같이 유창하게 번역을 하는 ...
stable, but the asteroid is a tiny thing in comparison and it is subject to the pull of Earth and moon and Mars and Venus as it moves so that its orbit is constantly shifting a little.Its orbit may shift so as to carry it farther from Earth, or possibly closer. To be sure, there is much more room away from Earth than closer, so the chance of its moving into a collision course is very small, ...
relative to the stars, and the ancient Babylonians found that five bright stars(the planets we now call Mercury, Venus, Mars, Jupiter and Saturn) did likewise. Since the sun and moon exerted an important influence on Earth, shouldn't these other stars do so, too? the ancients therefore invented planetary influences, based on various fanciful and mythological beliefs, and this was astrology.It ...
again and it will become a "white dwarf." About this small remnant, the outer planets will still circle, but Mercury, Venus, the moon, and Earth will be gone forever.But remember, this won't happen for billions years, so there's plenty of time for humanity and its descendants to prepare, assuming they avoid other kinds of disaster. Surely, by then, humanity will have practical interstellar ...
