Here's how to calculate the year the starlight began its journey:<br /><br />* **Current Year:** We need the current year to perform the calculation. Let's assume the current year is 2024.<br />* **Light Years to Years:** A light-year is the distance light travels in one year. So, if a star is 1106 light-years away, the light we see from it left the star 1106 years ago.<br />* **Calculation:** Subtract the light-year distance from the current year: 2024 - 1106 = 918<br /><br />Therefore, the light you saw last night left the star in the year **918 AD**.<br />
