Is it true theyve just discovered a planet that is mostly water?

Answer 1

You've got a bit of a problem here because there were two announcements fairly close to each other (within a week or so), the first was about the discovery of water in the atmosphere of a Jupiter-sized planet HD209458b, see Mukund's detailed coverage above.

Everyone else has assumed you're talking about Gliese 581c which is estimated to be about 5 times the mass of Earth and orbits at about the right distance from its dim red dwarf star that the temperature should be between 0 and 40 degrees Celsius (say 30 to 100 F). There is as yet no evidence for water on this planet

Answer 2

An odd planet the size of Neptune, made mostly of hot, solid water, has been discovered not far from Earth and offers evidence that other planets may be covered with oceans, European astronomers reported on Wednesday.
Called GJ 436b, the planet orbits quickly around a cool, red star just 30 light-years away, the team at the Geneva Observatory said.

Answer 3

No, NASA has not found any living creature at all on any planet. They discovered tiny flakes of frost on the moon. Not water. Frost. Mixed with dirt. Just a wee amount. Not enough for a glass of water even if you melted and purified all of it. @-sativamama ... What a genius you must be (rolls eyes). The first astronauts did not "all resign", they retired. That's what people do when they hit age 65. If they did not then there would be no positions open for new astronauts. And Armstrong's comments about 'the protective layer of truth' referred to the massive challenges involved in space exploration, not a conspiracy to keep them quiet about alien space stations on the moon or some such nonsense. Wake up.

Answer 4

We discovered a planet that is exactly the right distance from its particular sun, that if the chemical compound exists on the planet, then it will be in liquid water form. As in, not vapor, not ice, but water.

We don't know that the planet contains water. We also don't know if the planet can harbour life. What we know is, out of all of the planets that we have ever found, this one has the highest probability of harbouring life.

Answer 5

nope. they did find a planet that is about the same distance from a star as we are our star and could possibly be inhabitable and have liquid H2O, (POSSIBLY). however, it's bigger than the earth so we would weigh a lot more on that planet and its a gazillion miles away.

Answer 6

yes, almost exactly like earth

Answer 7

Not at all;
