Our Sun is an incredible fusion machine that has been churning out energy for approximately five billion years. In another five billion years, when the internal temperature of the star begins to change, the balance between the thermal pressure pushing outward and the force of gravity pushing inward will become imbalanced, and the Sun will move on to the next stage of its life. But that is a topic for a future column. Let’s turn back the clock, instead, and look at the early life of our star. Also included in this month’s column is an outline of celestial events during the month of October.
