Because Google is always in the running events of its day Doodle is dedicated to the seven planets found to be orbiting a dwarf star and announced yesterday by NASA.
According to the space agency of the USA, the star-dwarf it is 40 light-years away from our planet (a cigarette's way). 
The planets discovered by NASA, according to the announcement of the space agency, are similar in size to Earth and have similar temperatures on their surface. This means that it is probably on their surface water in liquid form, which for scientists is considered a very good indication of the presence of life.
According to the scientists who made the announcement, the most suitable living conditions for the seven discovered planets prevail in at least three of them. Scientists are optimistic that three out of seven have the potential to find oceans.
Because this is a very rare discovery (for the time being, and with the technical means of exploring the space we have), Google has dedicated today's Doodle to NASA's NASA revelation, which became the front page of all media.
