Cool Things! (Vol 2.3)

Hello, everyone!

Welcome to the April 2021 issue of Cool Things! Each month, we want to bring you news on scientific discoveries, historical information, and other interesting finds from across the internet. We have a lot to share today, so let's dive in!


NASA's Answer to Mini Museum

Later this week, the Martian rover Perseverance is set to deploy a solar powered helicopter on the red planet's surface. The helicopter, known as Ingenuity, will serve as a scout for the rover and will also be the first powered flight on another planet! To honor this achievement, a small swatch of fabric was attached to the machine; one that was once a part of the 1903 Wright Flyer. Not too different to what we do here at Mini Museum! (though our museums have yet to end up in space)


Billions and Billions of Stars

The night sky is as beautiful as it is vast, and humans have been staring into it since the beginning of our time on Earth. Those of us fascinated by it have always wanted to see more. This map from the Legacy Survey Sky Images should help satisfy that curiosity. Compiled by pictures taken from 3 telescopes over 6 years, the map contains over 1.6 billion objects within it: stars, galaxies, quasars, and more. The map was built in the hopes of creating a 3d rendering of the night sky, but the full thing can be viewed in your browser right now! Check it out!


The First Coppersmiths

Human use of copper dates back a long time, with artifacts in the Middle East going back to 9000 BCE. What you might not know is that on the other side of the world, Native Americans were using copper in just the same way. In fact, according to new research, Native American cultures may actually predate the rest of the world in copper tools by about 500 years!

The coppersmith culture of the Americas lasted between 9500-7000 BCE, possibly making it the oldest in the world. Curiously, tools after this date go back to being made of stone and bone. It's not that the knowledge was lost though; replica testing shows that the bone tools were just as effective as copper and easier to make too. If you're interested in learning more about how copper was used in the ancient world, you can read more on our site!


Visit an Alien Planet!

Looking for a fun vacation spot? Try TIRA 292b, home of the Tentaclastome! This planet is part of a spectuative series by Youtuber Biblaridion called Alien Biospheres. This project explores the evolution of life on a fictional planet. Biblaridion explores the progress on TIRA 292b through a scientific lens, explaining concepts of ecology, climate, evolutionary biology, and more! Plus, he's included some amazing illustrations of the strange creatures that appear on this alien planet! You can check out the full playlist here, but watch out for the elephant spiders!


An Ancient Shark with Wings?

As strange as alien biology is, you don't have to look far on Earth to find some crazy creatures either. A new study in Science examines the Aquilolamna milarcae, a 90 million year old shark with wing-like fins. These fins stretched out almost 2 meters, or 6 and a half feet!  Aquilolamna's strange fins allowed it to glide through the water in the way manta rays do today. What makes this find especially interesting is the preservation of body shape, as most ancient sharks are only known today through their teeth. Learn more about this strange shark here!


When the Land Came to Life

Without plate tectonics, the Earth would look a whole lot different. The shifting of continents is what keeps our planet dynamic and habitable for us, but it wasn't always that way. The origin of tectonics has always been a topic of some debate in the scientific community, but new information sheds light on when this phenomenon may have started.

By extracting and dating tungsten from ancient rocks, scientists have made a probable case for the first shifting of plate tectonics to have occurred around 3.2 billion years ago. It's old, but not as old as Earth itself. In fact, stromatolites from bacteria date back 3.9 billion years, meaning some life was able to survive well before tectonics began. Thanks to continental collisions though, the environment changed to allow life more complex than bacteria to come into being.

You can read the full article on the study here and collect some tectonic rift material of your own on our site!
