Because h Google is always in the current events of today Doodle is dedicated to the seven planets found to orbit one αστέρι-nano and were announced yesterday by NASA.
According to the US Space Agency, the star-dwarf is at a distance of 40 light years away from our planet (a road cigarette). 
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.winee.g. This means that there is probably water in liquid form on their surface, 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.
So since this is a very rare discovery (for now and with the technical means of space exploration at our disposal), Google dedicated today's Doodle to yesterday's NASA revelation that made headlines all over Media.
