FEMALE STUDENT: ...so more solid substances are available to clump into protoplanets, right?MALE PROFESSOR: Precisely! So the solid cores of the gas giants could conceivably have formed by accretion. And once their mass reaches a certain point, around about 5 to 10 Earths, what would happen...
A new study focuses on K2-18b, an exoplanet(系外行星) discovered in 2018, which orbits a red dwarf star close enough to receive about the same amount of radiation from its star as Earth does from our sun. Recently, scientists have discovered gas giants that have water in their atmospheres...
great.Hence, the Jovian planets are often called giants.Also, because of their relative locations, the four Jovian planets are known as the outer planets, while the terrestrial planets are known as the inner planets.There appears to be a correlation between the positions of these planets and ...
While three planets have been detected in the Kepler-431 system, little is known about the shapes of their orbits. On the left are a large number of superimposed orbits for each planet that are consistent with observations. An international team of astrophysicists led by Princeton's Daniel Tama...
. Alcohols are actually a large group of chemicals, including methanol and pentanol, but it is ethanol that is used to create the alcohol found in beers and wines and other beverages. The other elements from glucose also join together to form carbon dioxide, which is given off as a gas....
. absolutely nothing. The fact that they are nearly identical in size is scientifically interesting; which one is a few kilometers bigger than the other matters not one bit.” Brown also added, “But, still, I will admit to having a bit of an emotional attachment to Eris, so, deep ...
If there’s liquid water deep under the surface of Mars there are a fewextremophilesthatmaybe able to survive there. Given the extreme cold, or pressure, or toxic gases of all of the gas giants, it’s very unlikely that anything could survive on/in them. Jupiter, Satur...

MALE PROFESSOR: Last week we discussed the formation of Earth and the other rocky planets—the planets in the inner solar system.Uh, s-so, what about the gas giants?Jupiter, Saturn, Uranus, and Neptune. Well, there's two theories.But first, let's recap.We believe our solar system began...
