A star is <b>an astronomical object</b> consisting of a luminous spheroid of plasma held

<b>fusion</b>, radiates to space as both electromagnetic radiation and particle radiation. <b>In astronomy</b>, the main sequence is a continuous and distinctive band of stars 
that appears on ... When <b>nuclear fusion</b> of hydrogen becomes the dominant 
<b>energy production</b> process and the excess <b>energy</b> gained ... Below this threshold 
are sub-stellar <b>objects</b> that can not sustain hydrogen fusion, known as brown 
dwarfs. <b>In astronomy</b>, the Pleiades, or Seven Sisters (Messier <b>object</b> 45), is an open star 
... off or suddenly turning on the <b>production</b> of <b>energy through nuclear fusion</b>. Stellar evolution is the process <b>by</b> which a star changes <b>over</b> the course of time. 
Depending on ... Initially the <b>energy</b> is <b>generated by</b> the <b>fusion</b> of hydrogen atoms 
at the core of the main-sequence star. ... Once a star like the Sun has exhausted 
its <b>nuclear</b> fuel, its core collapses into ... Brown dwarfs and sub-stellar <b>objects</b>[edit
]. A quasar (/ˈkweɪzɑːr/) (also known as a quasi-stellar <b>object</b> abbreviated QSO) 
is an ... But when radio <b>astronomy</b> commenced <b>in</b> the 1950s, <b>astronomers</b>

of hot plasma, <b>with</b> internal convective motion that <b>generates</b> a magnetic field <b>via</b> 
a dynamo process. It is <b>by</b> far the most important source of <b>energy</b> for life on Earth
