In space, ‘Interstellar Matter‘,
‘Cosmic Dust‘, and ‘Cosmic Gas‘ which are
made of hydrogen and helium, dispersed
widely throughout space over a long period
of time by various Factors, such as
‘Supernova Explosions‘ and the resulting
‘Black Holes‘ and ‘Neutron Stars‘, etc.
A Supernova Explosions is a phenomenon
in which a star explodes at the end of its life.
At this time, Heavy Elements such as Oxygen
and Carbon, etc. that made up stars and planets
are also dispersed widely throughout space,
becoming Materials for the formation of
New Stars.
Then, after a long time, these Elements
are exposed to collisions, condensation,
heating, cooling, high pressure, and other
conditions, and it is believed that
a New Star will be formed finally.
The table below shows a newly born
“Protostar” photographed by the Hubble
Space Telescope.
After a further period of time, the Protostar
will begin “Nuclear Fusion” that convert
Hydrogen into Helium, and will grow into
a full-fledged star like the Sun.
