fun fact: if a persons body odor smells good to you that means they have an immune system basically opposite of yours! this happens so the chances of finding a mate with the opposite immune system is greater and the chances that any offspring you produce together will have a stronger immune system is greater.

this is fascinating

A ‘Ring of Fire’ solar eclipse is a rare phenomenon that occurs when the moon’s orbit is at its apogee: the part of its orbit farthest away from the Earth. Because the moon is so far away, it seems smaller than normal to the human eye. The result is that the moon doesn’t entirely block out our view of the sun, but leaves an “annulus,” or ring of sunlight glowing around it. Hence the term  “annular” eclipse rather than a “total” eclipse.
