New Discovery! NASA Telescope Reveals Largest Batch of Earth-Size Planets Around Single Star

The first known system of seven earth size planets around the single star has been revealed by the NASA’s Spitzer space telescope. The area around the parent star where a rocky planet is most likely to have liquid water is one of the three planets firmly located in the habitat zone.

The discovery of the Greatest number of habitable zone planets found around a single star outside our solar system sets a new record. Liquid water could be able to found on all of these seven planets – key to life and that to under the right atmospheric conditions but the chances of life are pretty highest with the three in the habitable zone.

The system of planets is relatively close to us at about 40 light years (235 trillion miles) located in the constellation Aquarius. These planets are scientifically known as exoplanets because they are located outside of our solar system.

TRAPPIST-1 is the term stated for this exo-planet. The full form of TRAPPIST-1 is stated as Transiting planets and Planetesimals Small Telescope (TRAPPIST) in Chile. TRAPPIST researchers announced that they have discovered three planets in the system. European southern Observatory’s very large Telescope along with the assistance of several group based telescopes, Spitzer discovered the 5 additional planets with the existence of 2 planets, which increases the number of known planets in the system of seven.

The team precisely measured the sizes of the seven planets using Spitzer data and developed the masses of the six of them, which gives the average density to be estimated.

TRAPPIST-1 planets are likely to be rocky as based on their densities. The calculated observations will not only determine whether they are rich in water but also reveal the presence of liquid water on the surface. The mass of farthest exoplanet which is the seventh planet has not been estimated yet.

TRAPPIST -1 was observed by spitzer for nearly about 500 hours in the end of 2016. Spitzer is positioned uniquely in its orbit to observe transits of the planets which simplifies the complex architecture of the system.

Sean Carey, the manager of NASA’s Spitzer science center in Pasanda as Caltech/IPAC said that ‘this is the most exciting thing that he had ever seen in 14 years of spitzer operations and more secrets are surely to be revealed by the observations’.
