- That’s equivalent to the total luminosity of our sun, a medium-sized star that emits
這相當於我們太陽的總光度,一顆中等大小的恆星,它發出的是
- a luminosity of around 500 billion yottawatts.
亮度約為5000億yottawatts。

- thus its luminosity.
是以其光度。
- Keep in mind that luminosity is how much light a celestial object gives off, meaning it's

03:32
- First off, with more mass, the sun's luminosity — the amount of energy and brightness it gives off — would increase exponentially.

- As the star evolves, it grows in luminosity and actually eventually make the earth too warm for liquid water and thus life on our planet.
隨著恆星的演化,它的亮度會增加,最終會讓地球變得太熱,無法維持液態水,進而影響我們星球上的生命。

- You can use the principle of parallax toe, learn how far away a star is, or you can look at the stars luminosity to figure out how hot it ISS, and you can learn how to do both of these things and so much more right now in the astronomy course that's offered over at Brilliant, it's never too early or too late in life to learn something new, and what makes brilliant so special is that they help you learn the kinds of things that you were forced to and maybe struggled with when you were a kid.
你可以利用視差趾的原理,瞭解一顆恆星有多遠,或者你可以看恆星的光度來計算它的熱度,你可以學習如何做這兩件事,還有更多,現在在Brilliant提供的天文學課程中,學習新的東西永遠不會太早或太晚,是什麼讓Brilliant如此特別,他們幫助你學習那些你被迫學習的東西,也許在你還是個孩子的時候,你就會感到掙扎。
