A giant eyeball from a mysterious sea creature was found by a man walking the beach in Pompano Beach on Wednesday. Wildlife officials said it likely came from a swordfish but experts mused that it likely came from a giant squid, whale or large fish. (Source)

Mars in the Loop : This composite of images spaced some 5 to 9 days apart, from late April (bottom right) through November 5 (top left), traces the retrograde motion of ruddy-colored Mars through planet Earth’s night sky. To connect the dots and dates in this 2018 Mars retrograde loop, just slide your cursor over the picture (and check out this animation). But Mars didn’t actually reverse the direction of its orbit. Instead, the apparent backwards motion with respect to the background stars is a reflection of the motion of the Earth itself. Retrograde motion can be seen each time Earth overtakes and laps planets orbiting farther from the Sun, the Earth moving more rapidly through its own relatively close-in orbit. On July 27, Mars was near its favorable 2018 parihelic opposition, when Mars was closest to the Sun in its orbit while also opposite the Sun in Earth’s sky. For that date, the frame used in this composite was taken during the total lunar eclipse. via NASA

Is this the whole thing??? It’s the first time I’ve seen this version.

Ye

Yes, that’s the whole image
