Largest batch of Earth-sized Planet Found

NASA is always the first to reveal the box of surprise when it comes to research and discoveries related to space. The most prized possession of NASA is its Spitzer Space Telescope which keeps an eye on every amazing thing happening in the universe.

Recently, it has found the largest batch of planets belonging to habitable zone category. These planets have the same size as that of earth and are seven in number. The reports suggest that there is a possibility that all of these could have water, which is the major key to the origin of life. Under right atmospheric conditions it could give birth to living organisms, but amongst all the seven planets, three are sure shot findings.

The associate administrator of Science Mission Directorate has told that this could be one of the greatest achievements of NASA. The burning matter of present day is to find out whether our earth is alone or it has the soul sisters also.

The priority is to find out habitable planets resembling Earth which has a similar atmosphere and living conditions. About 40 light years away, there exists a system of the world belonging to the constellation named Aquarius. Although these planets are relatively close to earth but scientifically known as exoplanets because these are located outside our solar system.

This exoplanet system is known as TRAPPIST-1 i.e. The Transiting Planets and Planetesimals Small Telescope in Chile. The researchers had already revealed that they had found three Earth-like planets with the help of the ground based telescope. However, Spitzer could confirm the existence of only two of those planets, along with the discovery of five additional ones. Hence, the total number of planets that will be considered for research work is confirmed to seven now.

Using the Spitzer data, the scientists tried to measure the relative mass of all these planets. After this, they estimated the density of these planets with the help of the data available to them. Based on their densities, the reports are made which suggests that the surface is covered with rocky areas majorly.

The reports were presented on Wednesday in the journal named Nature, and the briefing was given which addressed NASA Headquarters in Washington. It is said that this is the first time scientists have found the habitable planets in the large batch, and this can further help them to carry out other research work.
