Google lauds NATO for exoplanet discovery, tries a Doodle of earth
The Doodle features a telescope looking out towards space from a circle, representing the earth, with the moon by its side
Google has dedicated a Doodle for scientists in NASA discovering seven exoplanets beyond Solar system revolving around a small, cold star- which may point to the possibility of liquid water and life. The announcement was made yesterday by the space organisation and is considered as the biggest announcements made by it yet.
The Doodle features a telescope looking out towards space from a circle, representing the earth, with the moon by its side. Scientists have said that they need to make sure that the atmosphere of the rocky planets offers a hospitable environment for life.
The newly found planet system has been located inside our galaxy less than 40 light-years away in the constellation Aquarius. The scientists found the planets as circling around the cool, dwarf star called Trappist-1, which in size roughly makes to Jupiter and is almost 200 times dimmer than the Sun.
According to NASA, three of those planets found were in a "hospitable" condition and added that the planets were very likely to be supporting life.
They said that the possibility of such planets existing in our galaxy was overwhelming. “There are 200 billion stars in our galaxy. So do an account. You multiply this by 10, and you have the number of Earth-size planets in the galaxy – which is a lot,” The Indian Express quoted Emmanuel Jehin of the University of Liege.
The scientists added that the orbit of the exoplanets around the Trappist-1 was a lot similar to Jupiter and its orbiting moons, that means the exoplanets had been inside our galaxy, all seven planets would be inside the orbit of Mercury.
