Our Milky Way is home to at least 17 billion planets that are similar in size to Earth, a new estimate suggests. That’s more than two Earth-size planets for every person on the globe. It’s the first reliable tally of the number of worlds outside the solar system that are the size of Earth, but the hunt for our twin is far from over. The Planet Venus is also a twin but its characteristics are unlike that of our Earth. One might say these are Dr.Jeckyll and Mr.Hyde in our galaxy. This evil twin is quite something else. What the scientists presently were looking planets that could host us in some far distant time.
Despite the explosion of exoplanet discoveries in recent years, one find remains elusive: A planet that’s not only the right size but also in the so-called Goldilocks zone where it’s not too hot or too cold for water to be in liquid form on the surface.
These are all evolved out of the Big Bang where energy borrowed has created planets to settle and hold their orbits. Chance happenings within our Cosmos have ways of becoming certainties; and death and birth of stars also cause stars to form elsewhere in space. So we might consider them all in context of Space Time Frame. Upon this millions of spacetime frames could be drawn.
This leads us to the question: where lies really our true centre? We are star children since elements that make up our body is by courtesy of death rattle of stars we call supernovae. Recent discovery of Higgs Boson or God’s Particle also points to the mass. It owes to this particle. Thus we have a cosmic origin, but millennia of living has erased our ancestry. By way of compensation we acquired fluency for live on the Earth. The Earth is our cradle to which we have fallen from the stars, so to speak. In Christian theology this is our fallen state.
Scientists have calculated 17 percent of distant stars have planets that are the same size as Earth or slightly larger.
The findings were presented at the American Astronomical Society in Long Beach, Calif.
Meanwhile, the Kepler spacecraft continues to spot planets as they pass between Earth and the star they orbit. It found 461 new candidate planets, bringing the total to 2,740 potential planets, said mission scientist Christopher Burke at the SETI Institute.
