An exoplanet is a planet outside of our solar system. 系外行星是太阳系之外的行星。 Most exoplanets orbit different stars in the galaxy. 大多数系外行星围绕星系中的不同恒星运行。 However, astronomers have observed some planets that are independent of any star system. 但是,天文学家已经观测到一些...
To weed out these binary stars and harvest the true planets, it is necessary to conduct follow-up observations with spectroscopy. To do so, the team used observations from NEID and two other spectrographs: the Habitable-zone Planet Finder (HPF) on the 10-meter Hobby Eberly Telescope at McDo...

Pluto so that the two planets remain in orbits that cross, Pluto has not cleared its own orbit and was therefore demoted from planet status to that of a newly created category,dwarf planet.Like a planet, a dwarf planet orbits the sun, is large enough to assume a nearly round shape, and...
【解析】 28.C .细节理解题 ;由第三段"One of the key factors for a planet to be habitable is that it remains about the right distance from its main star to be neither too cold nor too ho t."可知,宜居的一个关键因素是与他的主要恒星 保持适当的距离,这样就不会太冷或太热,故选 C、 29...
Since 2009, the Kepler mission has tallied 989 confirmed exoplanets in the Milky Way; once the James Webb telescope launches in 2018, that number should rise. But do any of these have conditions as cushy as ours-what astronomers call "superhabitable"? To make a ballpark assessment, a team ...
It is now believed that planets are more common than stars, that some 40% of sunlike stars have planetary systems, and that roughly one quarter of all stars have potentially habitable planets. The CoRoT (launched 2006) and Kepler (launched 2009) space telescopes, especially the latter, ...
根据划线单词所在句To be considered habitable, planets must orbit a stable star that keeps a temperature suitable for liquid water.可知,要想被认为适合居住,行星必须围绕一颗稳定的恒星运行,并保持适宜液态水的温度。结合常识我们知道,行星一般是围绕着恒星转动的,由此可知,此处划线单词“orbit”的意思是“围绕...
