Why is Jupiter a gas planet? Why don't Kuiper belt objects show tails? How did the Comet Hale-Bopp get its name? What is the purpose of the Oort cloud? Why are there no planets in the asteroid belt? Why is Jupiter an outer planet?
Why is Jupiter the fastest spinning planet? What is unusual about the rotation of Venus? Why did Ptolemy believe in the geocentric model? Which of the following most likely explains why Venus does not have a strong magnetic field? A. it is too close to the sun. B...
Is it to see if there's life on them? 是要看看它们上面有没有生命吗? Cuz it seem to me like the only exoplanets we ever hear about are gas giants like Jupiter and Saturn that couldn't possibly support carbon-based life. 因为我好像唯一听过的外行星就是像木星土星那样的气体行星,这些星球不...
The word planet (in English) stretches back to antiquity, deriving from the Greek word "planetes," which means "wandering star." The five classical planets —Mercury,Venus, Mars, Jupiter andSaturn— are visible to the naked eye and can be seen shifting in strange pathways across the sky com...
Nevertheless, Europa is not a promising site to search for life because conditions may not have remainedstablefor the billions of years needed for life to evolve beyond the microscopic stage. If Jupiter’s moons interact gravitationally and modify their orbits, Europa may have been frozen solid at...
From the moon to Mars, scientists have been looking for water — the key to life — in the solar system for many years. Recently, they have turned to Jupiter(木星)! Jupiter is a gas giant(巨星). It doesn’t have an Earth-like surface. We can see strips(条纹) around it. They are...
Astronomers’ answer is:“If Earth can support life why can’t other planets do the same too? Astronomers have already discovered a Jupiter(木星)- like planet orbiting a Sun-like star so why not an Earth-like planet orbiting a Sun-like star?To achieve this goal though many other problems...
The dividing line between brown dwarfs and gas giant planets is generally considered somewhere between 10 and 14 times the mass of the solar system's most massive planet, Jupiter. That means we shouldn't find a planet with more than around 13 times the mass of Jupiter. Related: Bizarre 'fa...
Jupiter has different rotation periods per latitude, so devising a calendar system for the gas giant would pose a whole new set of challenges compared to terrestrial planets like Mars. ©NASA, ESA, STScI, A. Simon (Goddard Space Flight Center), M.H. Wong (University of California, Berkele...
FEMALE STUDENT: So, uh—exactly why are we interested in these exoplanets, anyway?Is it to see if there's life on them? 'Cause it seems to me like the only exoplanets we ever hear about are gas giants, like Jupiter and Saturn, that couldn’t possibly support carbon-based life…. ...
