Jupiter Still Has Water from 1994
It is known that the stratosphere in Jupiter is filled with water. This was delivered by a cataclysmic comet crash, on July, 1994, the comet, Shoemaker-Levy 9 crashed into Jupiter in more then 20 broken pieces. This crash gave Jupiter scars that are large enough to be seen by small telescopes on earth. Comets are made up of ice which dropped loads of water on Jupiter and a little on Saturn, Neptune and Uranus. Though the scientists are not sure if those three planets got the water from the comet because there are the other possibilities that there was a steady rain interplanetary (between planets) dust particles. Water vapor was first spotted in Jupiter's higher atmosphere by the European Space Agency's in 1997. Scientists are still thinking about other possibilities about where the water came from they are sure that the water hadn't risen from the inner part of Jupiters atmosphere because there's a vapor-blocking "cold trap" that separates Jupiter's stratosphere from the clouds in its troposphere that is below. Cavalié states in a report written by the ESA, "According to our models, as much as 95 percent of the water in the stratosphere is due to the comet impact," Cavalie also states, "All four giant planets in the outer solar system have water in their atmospheres, but there may be four different scenarios for how they got it."
This relates to what we have been doing in class because we have been talking about the stratosphere and troposphere that are on earth. I chose this article because I thought that it would explain whether or not the layers of the earth are similar, same, or different on different planets. This also relates on what we have been doing in class because we talked about different planets also the atmosphere on earth though this article talked about the atmosphere on Jupiter which was interesting because you get to compare. Overall I enjoyed this article though sometimes it was a bit hard to understand.
