For example, it's one of the planets that have liquid water. It has oxygen for us to breathe. Also, it has a very thick atmosphere (大气层)that protects us. And it has day and night. . I know that the sea is very big and deep. There are many kinds of fish and other sea ...
which likely prevents life as we know it from existing on the planets surface. " While these researchers found evidence for liquid water clouds on K2-18 b because of its lack of surface,rain wouldn't pour on the planet.Without a real surface,so to speak,landing on the planet would also...
An extrasolar planet (aka. exoplanet) is a planet that orbits a star (i.e. is part of a solar system) other than our own. Our Solar System is only one among billions and many of them most likely have their own system of planets. As early as the sixteenth century, there have been ...
Professor: Well, we have to consider its orbit. Gliese 581 e orbits its host star in a much shorter period of time than the other planets in the system, meaning it's very close to the star, and therefore too hot for water, for an ocean. However, the fact that it's relatively close...
Humanity’s exploration of the solar system has revealed much about the conditions on other planets. While no other planet shares the atmospheric makeup that has made Earth the home to so much life, many of them share aspects of Earth’s meteorology. The
A. There must be life on other planets in NASA says the planets are circling around a small nearby the solar system.star called TRAPPIST-1. The star is not hot like the sun. It's B. Since there's life on the earth, there must be life outside it.cool, meaning liquid water could ...
A rocky planet that could have liquid water at its surface orbits a star 490 light-years away. More resources on exoplanets: Exoplanets: Worlds Beyond Our Solar System Alien Planet Quiz: Are You an Exoplanet Expert? How Habitable Zones for Alien Planets and Stars Work: Infographic ...
This critical orbital range is where a planet can maintain liquid water on its surface – not too hot that it would evaporate away, nor too cold that it would freeze solid. Earth’s position within this zone is crucial for its vast oceans, a key ingredient for life as we know it....
From this and other evidence, scientists can conclude that Mars had liquid water in the distant past, and therefore, it must have had an atmosphere conducive to liquid water. What form this took is still being debated. Some posit that Mars was a cold world with equatorial waters, while oth...
Without an atmosphere, any living thing would die immediately and anything liquid would boil away into space. In other words, no one would last long if the planet didn't have gravity. If gravity were to suddenly double, It would be almost as bad, because everything would be twice as ...
