Today NASA announce that the Kepler space mission found a planet a closer to a twin of our own planet. This Planet orbits the star Kepler 452 and is named Kepler 452b. The star is 1.5 billion years older than the sun, about 20%bright than the sun and also 10% brighter. The planet orbits 5% further out than what the Earth orbits the sun, 1.6 times the radius of the Earth and orbits the star in 285 days. This mean it is within the goldilocks zone that is where water is likely to be in the liquid form. Right now we do not even know that there is water on the planet, We now need to find out what is in the atmosphere such as water. But we are getting closer to finding a twin to our own planet and maybe other civilizations.

Every once and while my interest in astronomy wanes and then there is something that sucks me back in like a black hole and today was one of those days. Today was the press conference from the team that sent the New horizons probe to Pluto. The discovered that there are mountains in southern part of the are they called the Tombaugh Regio (The heart shaped region on the Pluto), in this region are mountains 11.,000 ft tall that are made from rock hard ice covered with methane and other organic compounds. Also on Pluto and Charon there does not appear to be any impact craters which means the surface is relatively new covering up older impact craters. Since this means water must have flowed over the impact craters. But where is Pluto getting the energy to heat the water. The heat from the sun is too weak to do it, no tidal heating because you need something larger to tug on Pluto or Charon to create the tidal forces needed to do that. With organic molecules , an unknown energy source and possible liquid water in the interior could Pluto be on the same list of Europa, Titan and few other places in the solar but that is highly speculative.
Also on Charon there is a canyon that is about 4 miles deep. And the moon Hydra is a 28 x 19 miles long and highly reflective which means it mostly water ice.

About 4.5 billion orbits of the third planet around the main source of heat and light, clumps of mostly of ice and rock formed in the system. In this region the pieces of ice and rock collided, some broke into smaller and smaller pieces others formed larger and larger pieces. When some these pieces gained enough mass the force of gravity from one side attracted pieces from the other and these objects started to become spheres. Some of formed planets in the inner system, these were mostly made from rock. The next region of this system formed planets of rocky cores and layers and layers of hydrogen and helium. In between the objects of mostly rocky materials and the ones of mostly gas a belt of loss material formed. Further out another belt of small objects formed. These objects further out were composed of mostly of frozen substances that would be gases closer to the star in the center of the system. Some of these objects once and while would be nudged towards the center of the center of the system and when they got close to the star the ices would be released as gases. Particles of the star would be pushed away from the star and when the particles of the star hit particles of gases from the icy body a tail would form. One object in the outer belt formed into a sphere and a number of objects orbit around it, This object orbited the star once for every 217 the third rock from the star orbited the star once.
After about 4.5 billion orbits of the third rock living beings came about that could think about things around them. Some looked up at the sky at the many lights that would appear when the bigger light would go away. After time they noticed some these objects moved differently then the others. These lights wandered around while the others moved around in a regular way. After a long time they realized that they found more objects wondering around in the space around them and actually predicted where some of these objects should be before they found them. One of these objects a was a small icy sphere at the edge of the system. The beings began to send machines to the planets to get even a better look at them. The even sent a handful of beings to the object that orbited them. They eventually found more and more icy bodies out near icy body. The classification of the object was changed by the beings but the icy body didn’t notice. The beings sent a machine that would fly by the icy body with a little sample of the ashes of the being that found it only 85 years ago. As New Horizons fly by with a little bit Clyde. Pluto would care what is called, it will keep orbiting around the Sun.
