Life in space is speculative. Although it is likely to exist there is no evidence to confirm this speculation.
While traveling through the Solar System, you will discover nine planets. Four small terrestrial rocky planets and four large gaseous jovian planets. The outer most planet is the smallest. Other bodies in the night sky are comets, asteroids, meteoroids and meteors, plus of course, stars and galaxies.
Without the aid of the telescope and probes astronomers would be at a loss as to the marvelous phenomena that takes place in our universe.
A star begins as a collapsing cloud of gas in interstellar space, nuclear fusion starts up in the interior which causes a fusion process transforming hydrogen into helium and a star is born..
Stars can be compared with humans in the sense that they are born, they mature, they grow old, and they die.
