Twenty years ago, in 1995, the first extrasolar planet orbiting a main sequence solar-type star, 51 Pegasi, was detected (Mayor and Queloz1995). Nowadays, several thousand of exoplanets and exoplanet candidates are announced, dozens of them being located in the so called habitable zone: a zon...
Besides terrestrial planets in the conventional habitable zone roughly 0.7-1.5 AU from a Sun-like star, we realize that a moon of a Jovian planet in the habitable zone may be habitable, as well as a moon like Europa that is tidally heated. Habitable planets may exist in eccentric orbits ...
Unfortunately, scientists are still plagued by the fact that what we consider to be a "habitable zone" is subject to a lot of assumptions. Addressing this, an international team of researchersrecently published a paperin which they indicated how future exoplanet surveys could look beyond Earth-an...
in which he would find a well.“Ask the well what is1, ” he was advised, “and the well reveal (告诉,揭露)it to you.” Having found the well, the seeker asked that most basic and important2.And from the depths came the answer: “Go to the village crossroad, and there you shall...
Worden told The Associated Press: “I would certainly expect in the next four or five years we’d have an Earth-sized planet in the habitable (可居住的) zone.” 1. What is very important in determining if we are alone in the universe?
根据文章第二段Earth is the only known planet that stays in a perfect position from our Sun to support water in a liquid state.Astronomers call this perfect distance from a star the "habitable (宜居的)" or "Goldilocks zone".(地球是已知的唯一一颗距离太阳很近的行星,...
The age at which kids first fall victim to bullying (欺侮)could influence how strongly they are affected,suggests a new study. And,surprisingly,it is not the youngest kids who are hurt the most in the long term. Bullying can have long-lasting effects,but particularly when it begins in adol...
(模拟) time. That showed whether the planets would stay in orbit over timescales that might develop conditions to start life. They also checked to see if the planets stayed in a habitable zone. That’s the region around a star where an orbiting planet’s temperatures are never extremely hot...
