indicated thatstars in the night sky have planetary systems similar to our ownsolar system.___11___However,we have developed the technology to prove their existence only in thelast few decades.In 2015NASA’s Kepler space telescope found its first Earth-sized planet in a “habitable” zone. ...
故选E。【小题2】根据下文“However, in 2015 NASA’s Kepler space telescope found its first Earth-sized planet in a “habitable” zone. ”(然而,2015年美国航天总局的开普勒太空望远镜在一个“宜居”区域发现了第一颗地球大小的行星)可推知,大多数系外行星和太阳系的行星不同。B. Most exoplanets are ...
Habitable, But Not Much Like Home For the first time, astronomers have found an Earth-like planet that could be habitable. The rocky world orbits a puny red dwarf star just over 20 light-years away in the constellation Libra. ( Read more .)...
Such galaxies could also host 1 million times more gas giants, which can, in turn, host potentially habitable moons, the researchers added. "The most important implication of our analysis is that our cosmos is actually full of life," Mazumdar said. However, don't expect astronauts to visit ...
But the good reason to focus on these wavelengths is that’s where an Earthlike planet in the habitable zone around a sun-like star is going to shine brightest.” To the naked eye, Alpha Centauri as a single bright star, but the system is actually made up of a pair of binary stars,...
(68)___ However,in 2015NASA's Kepler space telescope found its first Earth-sized planet in a"habitable"zone.This is the distance form a star where surface temperatures of a planet wouldn't be too hot or too cold for liquid water.So far,only a small slice of our galaxy,the Milky Way...
4、[解析] 关键词是orbiting in the Sun's habitable zone。依据此关键词,可在文中第三段后两句找到相关叙述:“The planet also would have to orbit in a star's habitable zone. That's where the surface temperature would allow any water to exist as a liquid.”(这个星球应当是绕着可居住区域旋转...
Levy recently reported that the number of stars in the Milky Way galaxy that can have habitable planets circling them is much greater than previously believed. This could mean that life similar to that on earth might be much more probable among nearby stars.Anonymous...
"It could be that planets close to the edge of the habitable zone get way too much tidal heating, and they'd be too hot," Jackson toldSPACE.com. It also could be that planets just beyond the outer edge, which according to previous models would be too cold, might undergo enough heating...
Habitable planets refer to planets that have the potential to support life, specifically those that orbit at a distance from their host star that allows for the presence of liquid water on their surface. The presence of liquid water is considered crucial for the development and sustenance of life...
