Along the Milky Way

You can’t walk along the Milky Way. Still, under a dark sky you can explore it. To the eye the pale luminous trail of light arcing through the sky on a dark, moonless night does appear to be a path through the heavens. The glowing celestial band is the faint, collective light of distant stars cut by swaths of obscuring interstellar dust clouds. It lies along the plane of our home galaxy, so named because it looks like a milky way. Since Galileo’s time, the Milky Way has been revealed to telescopic skygazers to be filled with congeries of innumerable stars and cosmic wonders. via NASA https://ift.tt/3Al9pbQ

Wikipedia article of the day is Ambulocetus. Check it out: Article-Link Summary: Ambulocetus natans is a species of early amphibious archaeocete cetacean from the Kuldana Formation in Pakistan during the early Eocene, 48 or 47Β million years ago. It is among the most completely known Eocene cetaceans, vital to the study of cetacean evolution and the transition from land to sea. Ambulocetus probably had a long, broad, and powerful snout, and eyes near the top of the head. It may have hunted like a crocodile, waiting near the water’s surface and ambushing large mammals, using the jaws to clamp onto and drown or thrash prey. It may have swum like a river otter, alternating beats of the hind limbs while keeping the forelimbs tucked in for most of its propulsive power, simultaneously undulating the torso and tail. It had four functional limbs and may have walked much like a sea lion. It possibly had webbed feet and lacked a tail fluke. It lived in a hot, coastal swamp, probably in a river mouth.
