網頁2024年9月6日 · We measure the brightness of these stars using the magnitude scale. The magnitude scale seems a little backwards. The lower the number, the brighter the object is; and the higher the number, the dimmer it is. This scale is logarithmic and set so that every 5 steps up equals a 100 times decrease in brightness. 網頁2 天前 · Somewhere in a remote stretch of forest near Maine’s border with Canada, rocks from space crashed to Earth and may be scattered across the ground — just waiting to be picked up.

網頁2024年4月23日 · Space and Astronomy. The apparent brightness of a star is proportional to 1 divided by its distance squared. That is, if you took a star and moved it twice as far away, it would appear 1/4 as bright; if you moved it four times the distance, it would appear 1/16 as bright. The reason this happens is simple. int1016 spssris01網頁If the Earth is flat, then the vanishing point should intersect the horizon line. But they are clearly above the horizon line.
