From the heart shaped craters on Mars to the muscle pumping blood in your chest, Weird Science hopes you will accept this thread as a heartfelt Valentine’s Day gift.

There are approximately 75 trillion cells in your body and your heart pumps blood to almost all of them. Almost all, you ask? Yup, transparency is essential to your corneas so they are the only part of your body without blood vessels.

This blue whale exhaling a heart-shaped rainbow wants you to know that they have the largest hearts on Earth.

An octopus has 3 hearts. 2 keep the blood flowing past its gills and 1 keeps the blood pumping to its organs. What’s even weirder is the organ heart stops pumping when the octopus swims, which is why most octopi prefer crawling on the sea floor. Swimming is exhausting.

Frozen nitrogen covers part of Pluto's surface in a heart shape. When it’s day, a thin layer of this nitrogen ice warms and turns to vapor. At night, the vapor condenses and once again forms ice. Each sequence is like a heartbeat, pumping nitrogen winds around the dwarf planet

Even vegetables have hearts.

According to Greek myth, Zeus wanted to “have” the nymph, Cynara. He took her to Olympus but couldn’t control his anger when she wanted to visit her Earth-bound mom. So, he turned her into a spiky vegetable with a tender heart: the artichoke.

Let’s remember the humble sea star, who will remain, forever and always, heartless.

I’m going to leave you with one last thought. Hearts circulate what bodies need. Weird Science over and out.
