NASA-the organization that found the new planet-is always looking for planets with similar conditions to the earth’s. Space scientists Thomas Barclay says that we should think of Kepler-186f as an “Earth Twin”. Like our planet, it is made of rock. It is also likely to have water on...
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 ...
Pluto’s mean distance from theSun, about 5.9 billion km (3.7 billion miles or 39.5astronomical units), gives it an orbit larger than that of the outermostplanet,Neptune. (One astronomical unit [AU] is the average distance fromEarthto the Sun—about 150 million km [93 million miles].) It...
Slated to land on Mars this month, the Perseverance rover will search for signs of past life and test new technologies for supporting future human missions.
IT’S the planet we’ve all been waiting for. Earlier this month, rumours swirled that astronomers had discovered an Earth-like planet orbiting the closest star to our own, the aptly named Proxima Centauri. Well, the planet’s real, but don’t pack your interstellar bags yet...
NASA/JPL-Caltech A giant planet is orbiting the remnants of an exploded star – called a white dwarf – 1200 light years away from Earth. The discovery is the first time an entire planet has been found orbiting a white dwarf. Thefirst hint that there may be planets orbiting...
Earth 2.0 discovered, may be capable of supporting lifeAstronomers say the planet may hold water on its surface and is the best candidate yet of a habitable planet in the ongoing search for an Earth twin (Picture: AP/NASA) Dr Quintana is the lead author of a scientific paper detailing the...
(NASA的卫星发现了行星LP 890-9b,它比地球大30%左右,在2.7天内围绕它的太阳LP 890-9运行。)”和最后一句“That’s when the scientists discovered another planet, LP 890-9c, which is 40% larger than Earth and takes 8.5 days to orbit its sun.(就在那时,科学家们发现了另一颗行星LP 890-9c,它...
There is also a planet called Gliese-581g,discovered in September 2010, which is thought to be even more like Earth than Kepler-22b in terms of its suitability for plants and animals. It’s only 20 light-years from Earth – a lot closer than the newly discovered planets, though there ha...
