James Webb is waiting for the largest telescope in history. This is the first image of the

review by those in charge. Do not be deceived by these small spots that
is hardly apparent. Because in every bright spot that appears here was it or

a billion stars. But what does this picture or the other benefit us? And what can be

the Big Bang. They predicted that the telescope would be ready for
by the year two thousand and seven. It will cost five hundred million dollars only.
, but the accounts differed greatly. The launch date has been delayed to the year two thousand
and twenty-one. As for the cost, which was estimated at five hundred
a million dollars has ballooned to ten billion dollars. The
preliminary images taken by the telescope were revealed in the presence of the

In addition to studying the geological components of planets outside
the solar system. In your opinion, will the telescope achieve the expected benefits from
