Research has found that planets very similar in physical and chemical composition to our home Earth are though hard to find but not quite rare, rather quite abundant in our universe.
Scientists behind this assumption have also stated that one can also make their very own habitable world that could sustain intelligent beings just by following their chemical recipe.
Courtney Dressing, a Harvard grad student pursuing research in Astronomy stated:” Our Solar System isn’t quite that unique as we had previously anticipated”.
She has made this assertion based on data from the HARPS-North (High-Accuracy Radial velocity Planet Searcher, Northern) instrument on the 3.6-metre Telescopio Nazionale Galileo in the Canary Islands. It is carefully designed to precisely measure the masses of small, Earth-like planets. She further stated that once we have mass and volume, we can get Density and therefore a fair of idea of what that planet is made of and this tells us whether it can be like Earth or not.
Through this data, we can say that a rocky exoplanet has the same basic ingredients as Earth, she further said.
Boffins from Harvard even came up with a recipe to cook up a world with the same Earth like features.
1 cup silicon
2 cups iron
2 cups oxygen
½ teaspoon aluminum
½ teaspoon nickel
½ teaspoon calcium
¼ teaspoon sulfur
