Astronomers are continuing their  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes for life in the universe with new methods. Recently, they have started to  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes stars that have planets where life may be found. As there are billions of such stars outside our solar system there may be a chance of finding life. Every star has, on average, 1.6 planets  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes them.

Up to now astronomers have located about 400 stars that have the building  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes of life - primarily the  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes of liquid water. Only a handful have already been examined but, up to now, nothing has been found.

One of them, Gliese 581, is currently under  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes by astronomers. It is a red dwarf star, one of the most  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes in the Milky Way, about 20 light years away from Earth. Gliese 581 is about 10 billion years old and has a  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes that is only a third of our sun’s. Of the six planets orbiting around the star, two of them may have Earth-like  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes. One of them is about three or four times as big as our Earth and the right  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes away from its sun to have life.

Australian astronomers have started to take a closer look at Gliese 581 by combining radio signals of several  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes that are far apart from each other. Although the result was negative, the astronomers found out that this method provided an effective way of  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes the universe, one small section at a time. It allows them to observe the area with great  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes.

Patience is  accuracyblockscommondistanceexistencefeaturesmassobservationorbitingpinpointrequiredscanningsearchtelescopes by astronomers because hundreds of thousands of searches of this kind must be done before there may be a positive result.
