Two planets discovered last year are in the right orbit and might be good candidates for life, Quintana says, but they are a bit bigger than Earth. "For the first time, we can actually say we now have a planet that is both Earth-sized and orbits in its star's habitable zone," sh...
根据第一段“With the fast development of astronomy, astronomers are eager to find a hint of the familiar: planets that resemble Earth. By pushing technology to the limits, astronomers ar idly approaching the day when they can find another Earth.(随着天文学的快速发展,天文学家们渴望找到一个熟悉...

We have been discovering planets orbiting around other stars. Still, most of those have been Gas Giants whose lives could not exist because there was no water, land, or atmosphere to survive. Whilst in our solar system, the rocky planets are closest to the Sun, and the gas giants are ...
A. It's the first time humans have found Scientists said three of the newly discovered planets are in seven planets like the earth.the so-called habitable zone(适居带). This is the are a around the B. It's the largest habitable zone humans parent star where a rocky planet is most ...
Professor: OK. We've been discussing the planets in our solar system and how some of the ones farthest from the sun were discovered. 教授:好,我们一直在讨论我们太阳系中的行星,以及距离太阳最远的一些行星是如何被发现的 Well, today I'd like to turn to what are called exoplanets and how rese...
As we’ve seen, it’s only a rough guideline. You probably want to check out the place first and make sure it’s truly liveable before you commit to a timeshare condo around Gliese 581. Do you think habitable planets are common in the Milky Way? Tell us what your perfect planet envi...
As seen on Earth, orbiting in the habitable zone means a planet is far enough away from the sun to allow for liquid water oceans, a characteristic that’s critical for life. The definition of a ‘habitable zone’ relies on several different factors, including thermal equilibrium and the prese...
What are some interesting things we have learned about Omega Centauri? It's pretty likely that Omega Centauri is the largest globular cluster in the Milky Way. At 10 million stars, it's much bigger than most, which have more like a million stars. Also, it has multiple populations in it...
from the rate of star formation,the fraction(小部分) of stars that have planets,the number of habitable planets circling each star,the fraction of planets that remain habitable long enough for life to evolve all the way up to the number of civilizations that are capable of...
