If you are checking a cell for a zero value and the cell is blank, the test evaluates to true. For example, if you have the following formula in cell A1 =IF(B1=0,"zero","blank") and B1 is blank, the formula returns "zero" and not "blank" as expected.
If the range might contain a blank cell, you should use the ISBLANK function to test for a zero value, as in the following example: =IF(ISBLANK(B2),"blank",IF(B2=0,"zero","other")) Note that the above formula returns "zero" if there is a zero value in the cell, "blank" if the cell is blank, and "other" if anything else is in the cell.
You must always use the ISBLANK formula first before you test for a zero value. Otherwise you will always return a "true" for the zero value, and never get to the test for the ISBLANK formula.
Part 1: The eclipse observed was a lunar eclipse. The sun is usually not visible during these eclipses. The moon is new during a solar, but full during a lunar. It is red during a lunar eclipse due to a reflection of the Suns light behind earth. It happens more often because Earths shadow is larger than the moons. The umbra is larger as well, so it lasts longer than a solar eclipse.
Part 2: The moon is in the full moon phase. The Earth is in between the Moon and the Sun. The umbra of Earths shadow is cast directly on the moon, casting out the suns light. A tint of the reddish color shines around earth from the Sun making the dark moon appear red. The moons axis is slightly tilted , so the umbra does not hit the moon every month. But when it does? It creates a lunar eclipse.
