According to a relatively new theory,disk instability, clumps of dust and gas are bound together early in the life of the solar system. Over time, these clumps slowly compact into a giant planet. These planets can form faster than their core accretion rivals, sometimes in as little as a th...
Why did rocky planets form closer to the sun and the gas giants farther away? One theory involves the solar wind, the steady flow of plasma that emanates from a star. When the sun first came into being, this wind was far stronger than it is today -- strong enough to blast lighter el...
Stresses the importance of understanding how the Earth formed about 4,500 million years ago to other fields of astronomic investigations. Earth's similarity with the other inner planets; Central problem in the formation of stars; Meteoric impacts on the lunar surface as evidence of enforced ...

The other, newer theory suggests that planets form by gathering millimeter-sized "pebbles" from the outer solar system drifting towards the Sun through a process known as accretion, condensing it all together through gravity to form these planetary embryos that would form the planet. ...
According to a newer theory, disk instability, clumps of dust and gas bind together early in the solar system's existence. Over time, these clumps can slowly compact into a giant planet. These planets can form faster than those that form within the core accretion explanation, sometimes in as...
How far away are they? Are they all the same? Are there otherplanetsaround them? In this article, we will look at the fascinating world of stars. We will examine the nature of stars, types of stars, how stars form and how stars die. If you have readHow the Sun Works, you already...
6.Listen again to part of the lecture. Then answer the question. (MALE PROFESSOR) instead of asking, “How did the rings form?” We should be asking… [looking for a response] uh, anyone? Beth? (FEMALE STUDENT) [tentative, upspeak] How do the rings form? (MALE PROFESSOR) How do th...
解析 move 【详解】 句意:你知道有多少行星绕着太阳转吗?分析题干可知,空格处是宾语从句的谓语动词,从句叙述的是客观真理,应使用一般现在时,不受主句时态的限制,从句的主语planets表示复数,所以空格处应填动词move“移动”的原形。故填move。反馈 收藏
the other parts, matter at the perimeter was pulled toward the center. whereas matter in the center, because it was pulled equally from each side, did not move at all, and thus the nebula contracted with the greatest concentration of matter occurring in a central region called the protosun....
