Hey guys, science is cool.
But let’s unpack some of that scenery. Diplodocus, Apatosaurus, Allosaurus, Stegosaurus and their neighbors roamed western North America about 150 million years ago. This slice of time falls in the latter portion of the Jurassic. The traditional representatives of the latest Cretaceous scene—Tyrannosaurus and Triceratops—did not evolve until about 67 million years ago. By themselves, these dates are just labels, but think of them falling along evolution’s timeline. About 83 million years separated Apatosaurus from Tyrannosaurus and Allosaurus from Triceratops. The so-called Age of Mammals—which began when the non-avian dinosaurs were wiped out—has been going on for about 66 million years. Less time separates us from Tyrannosaurus rex than separated T. rex from Stegosaurus.
The film visualizes what’s said to be the most accurate model for measuring the expansion of the universe. The model, produced at the International Centre for Radio Astronomy Research (ICRAR), in Australia, is based off of the Hubble constant and a massive trove of data on galaxies called the 6dF Galaxy Survey.
I truly enjoy outer space. It’s absolutely amazing that we now have the ability to send instruments out into the void of the universe to observe all sorts of interesting things. Asteroids! Moons! Planets! Dark matter! This is the perfect opportunity for a Carl Sagan quote:
“Somewhere, something incredible is waiting to be known.”
The footage in this little film was captured by the hardworking men and women at NASA with the Cassini Imaging Science System.
This subtle and thoughtful video uses Carl Sagan’s The Pale Blue Dot (some of the best writing ever), and is perfect.
I can’t figure what I’m more fascinated with about the above picture; that it’s the closest and most detailed picture of a sunspot ever taken; or the fact that it looks exactly like Sauron from Lord of the Rings. As J.R.R. Tolkien was essentially my girlfriend from 6th grade until I finished high school, I’m leaning towards the latter. Midget bro love has never been written better. They weren’t gay. They were hobbits.
