Is this the longest year in the UNIVERSE? Bizarre planet takes 80,000 Earth YEARS to orbit its sun


A gas giant planet has been found in a large orbit around a distant star
Called GU Psc b it takes the planet 80,000 years to complete an orbit
It is 2,000 times further from its star than Earth is from the sun
This distance, a record among exoplanets, has allowed it to be imaged
And it could lead to the discovery of smaller planets in tighter orbits

We can't be the only life forms in the universe. I'm still waiting for an ET to land in my backyard.
Live life to the fullest while you can... The ET's may not be friendly when they arrive!!!!

Astronomers Confounded By Massive Rocky World


Astronomers have discovered a rocky planet that weighs 17 times as much as Earth and is more than twice as large in size. This discovery has planet formation theorists challenged to explain how such a world could have formed.

"Just when you think you've got it all figured out, nature gives you a huge surprise – in this case, literally," said Natalie Batalha, Kepler mission scientist at NASA's Ames Research Center in Moffett Field, California. "Isn't science marvelous?"


It appears many shouldn't be explaining the "facts" of the universe.

You look to be totally clueless of Science and tech.

Are you being just dismissively religious? "It ain't in the 2000-year-old-unchanging-bible and so it can't be true?"

Or just some bored grumpy old troll?


Keep searchin', you might find something...

Repeating yourself again Batter Up?

Just because you can't understand things doesn't mean that others can't.

Stick to politics where you are at least slightly enlightened.

Cheers.

Now here's a brilliant way to connect Science Fiction and Science Fact and the public:


Boffins publish SciFi story to announce exoplanet find

Brit author Alastair Reynolds explains habitable zone planets around Kapteyn's star

Boffins from the Queen Mary University of London have chosen an unusual way to announce a new exoplanet find, commissioning a short story describing the recently-revealed worlds...

The question is always the same?

Potentially habitable Super-Earth Gliese 832 c appears in an artist's conception against a background of a stellar nebula.

A newfound alien world might be able to support life — and it's just a stone's throw from Earth in the cosmic scheme of things.

The planet, called Gliese 581G

Study debunks a ‘Goldilocks’ planet thought to potentially support alien life


The discovery four years ago of a rocky, not-too-distant planet was a thrilling development in the search for alien life — proof, it seemed, that our planet might not be the only one with just the right mix of life-sustaining conditions.

Looking for these planets is all well and good but in 4 billion years we are going to be a part of a tremendous train wreck when we slam head on into Andromeda and our planetary system could be torn apart or slung out of the galaxy. A billion years after that the sun dies. We cant just go to another star system let alone another galaxy. And going to another galaxy is what we are going to be forced to survive we have to.

You are an optimist.

During the next four billion years, the luminosity of the Sun will steadily increase, resulting in a rise in the solar radiation reaching the Earth. This will cause a higher rate of weathering of silicate minerals, which will cause a decrease in the level of carbon dioxide in the atmosphere. In about 600 million years, the level of CO2 will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees. Some plants use the C4 carbon fixation method, allowing them to persist at CO2 concentrations as low as 10 parts per million. However, the long-term trend is for plant life to die off altogether. The extinction of plants will be the demise of almost all animal life, since plants are the base of the food chain on Earth.

In about 1.1 billion years, the solar luminosity will be 10% higher than at present. This will cause the atmosphere to become a "moist greenhouse", resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics will come to an end. Following this event, the planet's magnetic dynamo may come to an end, causing the magnetosphere to decay and leading to an accelerated loss of volatiles from the outer atmosphere.

Exoplanet with the longest year discovered: Kepler-421b orbits its star every 704 days - and this changes what we know about gas giants

Kepler-421b was discovered using data from the Nasa Kepler spacecraft
It takes almost two Earth years to circle its star 1,000 light years away
This is the first example of a potentially 'non-migrating gas giant in a transiting system that we've found,' said lead author David Kipping
Scientists initially thought gas giants migrate inward in their early history

Hubble Finds Three Surprisingly Dry Exoplanets

Astronomers using NASA's Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the sun -- and have come up nearly dry.

The three planets, known as HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away from Earth and were thought to be ideal candidates for detecting water vapor in their atmospheres because of their high temperatures where water turns into a measurable vapor.

If they are small planets the water vapor would have escaped off into space as it did on Mars long ago.

Then why does Titan have an atmosphere. There are other factors that can be involved.
