Hubble Detects Exoplanet with Glowing Water Atmosphere

This result is exciting because it shows that a common trait of most of the atmospheres in our solar system -- a warm stratosphere -- also can be found in exoplanet atmospheres," said Mark Marley, study co-author based at NASA's Ames Research Center in California's Silicon Valley. "We can now compare processes in exoplanet atmospheres with the same processes that happen under different sets of conditions in our own solar system."

Reporting in the journal Nature, scientists used data from NASA's Hubble Space Telescope to study WASP-121b, a type of exoplanet called a "hot Jupiter." Its mass is 1.2 times that of Jupiter, and its radius is about 1.9 times Jupiter's -- making it puffier. But while Jupiter revolves around our sun once every 12 years, WASP-121b has an orbital period of just 1.3 days. This exoplanet is so close to its star that if it got any closer, the star's gravity would start ripping it apart. It also means that the top of the planet's atmosphere is heated to a blazing 4,600 degrees Fahrenheit (2,500 Celsius), hot enough to boil some metals. The WASP-121 system is estimated to be about 900 light years from Earth – a long way, but close by galactic standards.

This is kind of neat to watch.

Here's what I believe. There is was or will be life around most every star. There are planets and moons surrounding every star so I would assume life happens.

But people expect or hope for intelligent life. That I think is very rare. Human type intelligence might be one in a million. But there are billions of stars so that means other intelligent life exists.

So people ask why haven't they visited. Well why haven't we visited them? So I bet there is more intelligent life out there. They may have mastered the ability to travel to their nearest neighboring star in 10,000 years. They are already on the voyage. Now they have already learned that there's life beyond their planet but they don't know something as smart as us exists. So far all they know of are fish worm and insect type life. They may not be so smart theyve discovered us. We may be way over on the other side of the universe

Humans have been farming for 11,000 years. At the fastest speed we can go we can reach this planet in 80,000 years. I think we need to go to Mars and mine it and the meteor belt and build a planet size ship.

It won't matter how fast the thing goes because it is home. Engineers would constantly and always be replacing parts and sections of the ship.
