Search for Twin Earth Getting Hotter! --NASA Announces 11 New Planetary Systems Hosting 26 Confirmed Planets
In the past year astronomers have discovered smaller planets are more numerous and diverse than anyone has expected --"Searing hot planets with iron rain, atmospheres with 1,000 mile an hour winds, planetary systems with two suns, a planet that literally skims the surface of its star once every three months," reports Dimitar Sasselov, professor of astronomy at Harvard University.
NASA's Kepler mission's recent discoveries nearly double the number of verified Kepler planets and triple the number of stars known to have more than one planet that transits, or passes in front of, the star. Such systems will help astronomers better understand how planets form.
The planets orbit close to their host stars and range in size from 1.5 times the radius of Earth to larger than Jupiter. Fifteen are between Earth and Neptune in size. Further observations will be required to determine which are rocky like Earth and which have thick gaseous atmospheres like Neptune. The planets orbit their host star once every six to 143 days. All are closer to their host star than Venus is to our sun.
Kepler identifies planet candidates by repeatedly measuring the change in brightness of more than 150,000 stars to detect when a planet passes in front of the star. That passage casts a small shadow toward Earth and the Kepler spacecraft.
"Confirming that the small decrease in the star's brightness is due to a planet requires additional observations and time-consuming analysis," said Eric Ford, associate professor of astronomy at the University of Florida and lead author of the paper confirming Kepler-23 and Kepler-24. "We verified these planets using new techniques that dramatically accelerated their discovery."
Each of the newly confirmed planetary systems contains two to five closely spaced transiting planets. In tightly packed planetary systems, the gravitational pull of the planets on each other causes some planets to accelerate and some to decelerate along their orbits. The acceleration causes the orbital period of each planet to change. Kepler detects this effect by measuring the changes, or so-called Transit Timing Variations.
Planetary systems with Transit Timing Variations can be verified without requiring extensive ground-based observations, accelerating confirmation of planet candidates. This detection technique also increases Kepler's ability to confirm planetary systems around fainter and more distant stars.
"By precisely timing when each planet transits its star, Kepler detected the gravitational tug of the planets on each other, clinching the case for 10 of the newly announced planetary systems," said Dan Fabrycky, Hubble Fellow at the University of California, Santa Cruz, and lead author for a paper confirming Kepler-29, 30, 31 and 32.
Five of the systems (Kepler-25, Kepler-27, Kepler-30, Kepler-31 and Kepler-33) contain a pair of planets where the inner planet orbits the star twice during each orbit of the outer planet. Four of the systems (Kepler-23, Kepler-24, Kepler-28 and Kepler-32) contain a pairing where the outer planet circles the star twice for every three times the inner planet orbits its star.
Kepler-33, a star that is older and more massive than our sun, had the most planets. The system hosts five planets, ranging in size from 1.5 to 5 times that of Earth. All of the planets are located closer to their star than any planet is to our sun.
The properties of a star provide clues for planet detection. The decrease in the star's brightness and duration of a planet transit combined with the properties of its host star present a recognizable signature. When astronomers detect planet candidates that exhibit similar signatures around the same star, the likelihood of any of these planet candidates being a false positive is very low.
"The approach used to verify the Kepler-33 planets shows the overall reliability is quite high," said Jack Lissauer, planetary scientist at NASA Ames Research Center at Moffett Field, Calif., and lead author of the paper on Kepler-33. "This is a validation by multiplicity."
In the image below, all the colored planets have been verified. More vivid colors indicate planets that have been confirmed by their gravitational interactions with each other or the star. Several of these systems contain additional planet candidates (shown in grey) that have not yet been verified.

Soon all will take note to the sounds and rumbling of Volcanoes Around Earth that are Waking Up at a Alarming Rate.
Read well and study on your own after you have read this.
This is not a game or joke our Sun gives off a Solar Wind all day year round if you live in the State of Alaska you see it in the sky above what a sight it is going through our Earth’s Magnet Polls of the North and the South, North Poll. It’s called the Northern Lights or the Aurora Borealis.
The day will come when you will be able to see it all over Earth as in the year 1859 Solar Flare, It was the largest in 500 years. Two Astronomer’s Hodgson and Carrington told the World that the Solar Flare made a Geomagnetic Storm reach Earth in hours not days. Back then it gave new meaning to Reach For The Skies from Telegraph Operators. For hours sparks flew from the key board. Even after the Batteries were disconnected. Nov 3 and 4, 2003 had a X40+ Class Solar Flare.
Our Sun’s UV Rays will get stronger as each passing day goes by, read and i will tell you why.
The Great big forest have be stripped from most of the Earth for Greed of Money by the Wicked. The trees are our Main Source of Oxygen on this Plant.
The Forest Trees scrubs the Pollution out of the air and makes Oxygen from the rain and dirt that it grows in.
The Forest Trees do more than just make Oxygen they stop Soil Erosion, just Look at the 1930 Dust Bowl. Greed by our Government taxes led farmers to clear cut all their Forest and farm all the land they were being Tax on. They had to farm it to pay for the Taxes. Why leave the Trees when food crop makes Money. This Did not Help the Depression that effected most all Worldwide. This year 2012 more than 100 million will suffer from Malnutrition lack of food and Dehydration lack of water. Many will not make it and die!
Soon many will run out of Safe Drinking Water from pollution going into the worlds water supply.
In the United States of America alone more than 45 Million Americans Received Food Stamps and that number is going up every day every year for more than 3 years in a row now.
The Pollution and CO2 Carbon Dioxide go into the Tree Bark as a shield from most bugs so they do not eat the tree.
Less Forest less Oxygen this is why the moon. That has no Oxygen is very cold on the side with out Sun Light, And hot as ever on the side with Sun Light. Way too cold and too hot to live there. You would need at least 10 times the Energy we use on Earth to even live there and life on the Moon would be very short.
With no blank of Oxygen to lessen or reduce the Sun’s UV Rays and Solar Wind they are deadly there on our Moon. Every Mt. Climber and Aircraft Pilot knows the higher you go the thinner the Oxygen and colder it gets.
Just spend a night on a Mt. top above 13,000 feet with no Sun Light and you will see or should i say feel the cold stinging any of your exposed skin. If you are new to Mt. Climbing stay below 10,000Ft. The Astronauts and the Cosmonauts and Fighter Pilots that i have been with for years know this very well, and the Radiation Hazards to humans at High Altitudes.
Soon the Sun’s Solar Wind and UV rays will be way to strong for most to go out in the Sun Light for even a short time. The Geomagnetic Storm to come and the Bad Weather Storms well you have not seen nothing yet and the Sea Level is Rising the Oceans. Many Millions have been affected by Floods in China and Pakistan just last year. In 2005 Over a Thousand dead in New Orleans flood, and the list going on. The sounds and rumbling of Volcanoes Around Earth are Waking Up at a Alarming rate.
And there shall be famines, and pestilences, and Earthquakes, in divers places such as was not from the beginning of the Creation.
The last 30 years On Earth we have broke all High Temp Records and the temp it is still going up. All the Worlds Ice Glacier are melting at an Accelerating Rate. The Glaciers and Polar Ice Caps store more water than all the Fresh Water Lakes on Earth. Many of them are drying up or water levels are going down past the lowest point every recorded.
The Bad Weather Storms now are Babies compared to what is to come.
They will get even bigger and worse less Oxygen the more UV Rays to the Earth and more Water molecules will evaporate and go up into the Earth’s Atmosphere. Less Oxygen the colder without sun light and hotter with it.
The Sky full of more water vapor molecules, more snow in the winter and more Flash Floods in the Summer. All earth will see way more fires and the Deserts are growing larger.
If every living person on Earth were to Plant A Tree Today we might have a chance.
The Earth’s Atmosphere Blanket surrounding it protects life on Earth as Our Lord and GOD will all that seek Him.
Then it is written when the tree is full it is harvest time. All the Earth will someday burn away.
This is all Foretold in the Bible Read it
and may our Lord Bless all that do so.
The Lord’s Little Helper

P.S.
2 Peter 3:10
But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the Earth and its works will be burned up.
GOD Bless You and Your Love ones
Give thanks to our Lord Jesus Christ every day.

Earth is at its Limits
MANY OF US IN THE SCIENTIFIC COMMUNITY HAVE BEEN SAYING SOME OF THIS FOR YEARS
The United Nations is now taking a serious look into "Earth's Limits" Earth will very soon be at its Limits of no return for many things including all life on Earth.
If we keep going at this rate we will not have another 20 years to go back to Rio De Janeiro to play. Most all in the Scientific Community said this 20 years ago at the last time Leaders set up this meeting in Rio De Janeiro. Of course on the Tax payers money, and of course they said about the same thing again we need to do something!
There is enough Energy from our Sun to Power all are needs on Earth and more.
Solar Energy
The Fastest growing energy on Earth.
Albert Einstein 100 years ago showed the World it could get
Free Energy, Electric from the SUN. (THE PHOTOVOLTAIC EFFECT).
