NASA on Thursday announced the discovery of Kepler-452b, the most Earth-like planet ever found. Located 1,400 light-years from our planet, NASA called it "Earth 2.0," because it's the first planet discovered in the habitable zone of a G star similar to our sun. 周四,美国国家航空航天局...

While similarly sized planets have been found before, the latest one, known as Kepler-452b, is circling a star that is very similar but older than the sun at a distance about the same as Earth’s orbit. “It’s great progress in finding a planet like Earth that is similar in size and...
The researchers don't know if the super-Earth is rocky like our own planet, but it orbits the star every 55.7 days and has a temperature of negative 64 degrees Fahrenheit. An atmosphere could cause it to be warmer.科学家尚不清楚这颗“超级地球”是否和地球一样属于岩质行星，但它的公转周期...

But it's not a rocky planet, like Earth, which could make for insightful followup observations about how the atmosphere is composed and its evolution. 研究员认为,其密度表明迷你海王星的大气层很厚,但它并不像地球一样是一颗岩石行星,这可能有助于后续对其大气构成及演化进行深入的观察。 The star ...
NASA has been hot on the trail of Earth-like planets. Previous studies were forced to rely on one-dimensional and vertical models to simulate atmospheric conditions. The new research uses a model that calculates conditions in all three dimensions, allowing scientists to simulate the circulation of...

根据第四段“The planet’s atmosphere would feature something like Earth’s water cycle, but instead with sand cycling between solid and gas states. From the hotter, lower levels of the atmosphere, silicate vapour would rise up, cool and form tiny sands, too small to see. Eventually, these ...
