The clearest visible difference between manatees and their closing living relative, dugongs, is the presence of a paddle-shaped tail. A dugong’s tail flukes — similar in shape to that of a whale.

Manatees (family Trichechidae, genus Trichechus) can grow to weigh up to ~1,200 lb and be over 9 feet long! These marine mammals are mostly herbivorous and they are known to eat over 60 different freshwater and saltwater plants. 🥬🦭 #ManateeAppreciationDay https://t.co/m9NRqvyyLR

This is the skull of a common starling (Sturnus vulgaris) & it’s being viewed under a scanning electron micrograph (SEM) with animated coloring. 🐦🔬

The tissue found in the interior of this bird bone is characterized by a honeycomb arrangement of trabeculae.

This is a composite long exposure image from the International Space Station. NASA astronaut Don Pettit combined multiple 30-second exposures from a mounted camera on the space station into one image. ✨

The axis of the Earth is now increasing its tilt relative to the Sun, warming the hemisphere significantly. This causes new plant growth to “spring forth,” giving the season its name.

When galaxies collide, they can create tremendous starbursts. 

As gas follows that collision, shockwaves are formed, and a new generation of stars are born into the galaxy. 💫
