The most exciting news for astronomy fans in Taiwan this year, might be the lunar eclipse on Oct.8, and it's the first chance for people in Taiwan to observe the lunar full eclipse since Dec.10, 2011. People can see the eclipse with naked eyes, or take photos with common photography equipment.

The reason why lunar eclipse happens, is because the moon is passing through the Earth umbra (本影). At the very beginning, the shadow will start to darken the moon gradually. And then, when the time comes, the shadow started to "cover" parts of the moon, and turn its colour to dark-red. Some might wonder why the moon doesn't vanish anyway? Since the "lunar full eclipse" means that "it's covered by Earth umbra", it doesn't means that there's no light for the moon to reflect, therefore we can still observe the moon itself.

And why is the colour "dark-red"? Actually, according to astronomers, since the moon can't reflect the sunlight directly during the lunar eclipse, the earth atmosphere will scatter the long wavelength
 light, such as blue light away, and refract the short wavelength light, such as red lights onto the moon. In addition, if the earth atmosphere is clean and clear, the colour will appeared to be brighter red; on the contrary, it will appear to be dark red, if the earth atmosphere contains more ashes and dust.

The next lunar full eclipse will be at 2015.4.4, but if people in Taiwan wish to see it without traveling far away from home, will have to wait until 2018.1.31 to see its next visit to Taiwan!
