Ancient Bronze Age city reemerges from Iraq river after extreme drought

When an extreme drought caused a 3,400-year-old city to reemerge from a reservoir on the Tigris River in northern Iraq, archaeologists raced to excavate it before the water returned.

The Bronze Age city, at an archaeological site called Kemune, is a relic of the Mittani Empire (also spelled Mitanni Empire), an ancient kingdom that ruled parts of northern Mesopotamia from around 1500 B.C. to 1350 B.C. Researchers have long known of the remains of the city, but they can only investigate them during droughts.

Archaeologists partly excavated Kemune in 2018 and discovered a lost palace with 22-foot-high (7 meters) walls and chambers decorated in painted murals, Live Science previously reported. This time, researchers mapped most of the city, including an industrial complex and a multistory storage facility that likely held goods from all over the region, according to a statement released by the University of Tübingen in Germany.

Hubble fortuitously discovers a new galaxy in the cosmic neighborhood

Astronomers using the NASA/ESA Hubble Space Telescope to study some of the oldest and faintest stars in the globular cluster NGC 6752 have made an unexpected finding. They discovered a dwarf galaxy in our cosmic backyard, only 30 million light-years away. The finding is reported in the journal Monthly Notices of the Royal Astronomical Society: Letters.

An international team of astronomers recently used the NASA/ESA Hubble Space Telescope to study white dwarf stars within the globular cluster NGC 6752. The aim of their observations was to use these stars to measure the age of the globular cluster, but in the process they made an unexpected discovery.

Newly discovered Amazon rock art show the rainforest's earliest inhabitants living with giant Ice Age animals

Amazonian rock art newly discovered by researchers provides further proof the rainforest’s earliest inhabitants lived alongside now-extinct giant Ice Age animals.

The thousands of pictures are among the oldest depictions of people interacting with the huge creatures, including mastodons. Usually the only clues about their appearance are skeletal remains.

This is one of the largest collections of rock art found in South America. The recorded drawings, likely first made around 12,600 and 11,800 years ago, are on three rock shelters on hills in the Colombian Amazon. The paintings, identified during landscape surveys, also depict geometric shapes, human figures, and handprints, as well as hunting scenes and people interacting with plants, trees and savannah animals. The vibrant red pictures were produced over a period of hundreds, or possibly thousands, of years.

NASA’s Webb Space Telescope Reveals Astounding, Unprecedented Views of the Universe

New type of star system? Mysterious radio signal puzzles astronomers

After observing a part of the sky near the Southern Constellation of Ara for about two months using MeerKAT, a radio telescope based in the Karoo desert in South Africa, our team of scientists noticed something strange. The radio emission of an object brightened by a factor of three over roughly three weeks.

Intrigued, we continued watching the object and followed this up with observations from other telescopes. We discovered that the unusual flare came from a binary star system – two stars orbiting each other – in our own galaxy. The finding, published in the Monthly Notices of the Royal Astronomical Society, has, however, turned out to be very difficult to explain.

Here’s one good thing to come out of 2020:

Paleontologists completed a life-sized replica of Sue, the most complete T. Rex ever found.

And she is freaking GORGEOUS!

As I read more about this beauty, I found out some new details regarding things I thought I previously knew about the beast that was Tyrannosaurus Rex, and I’m going to share them with you.

First, and most obvious, her size:

This is nothing new, we all figured T. Rex was big, but I for one never stopped to consider exactly how big it was. Nobody ever really knows what to imagine when they read about something the size of a whale that walked around and ate everything it could kill. 

Speaking of eating things, I just want to remind you all that T. Rex had–by miles–the strongest bite of any terrestrial animal living or dead, somewhere around six and a half tons of force. That’s over six times greater than the current estimate of what Allosaurus was capable of, and three times what was delivered by the highest measured reading of the living title holder–the estuarine crocodile. It didn’t have to waste time swinging its head open-mouthed like Saurophaganax for a little extra oomph, or grow fancy serrated teeth like Carcharodontosaurus to cut pieces out of its prey. It opted for the simplest approach: get its mouth around something and crush it to death; imagine the full weight of an elephant on whatever was between this thing’s jaws.

“How did it find something to eat?” I hear you asking. “It can’t see something if it doesn’t move, right?”

Listen, I love Jurassic Park too, but that’s a big crock of shit.

Notice how both her eyes face forward. That gives her binocular vision (the ability to focus both eyes on one target, like you and I). More importantly it means she has impeccable depth perception due to overlapping fields of vision from each, large, eyeball. Researchers agree that T. Rex not only had incredible vision, but that it was probably better than most modern animals–including eagles, hawks, and owls–and that she could likely spot something three and a half miles away. If something that big can see that well, it doesn’t matter if you move or not, she’d be able to tell if it was an animal trying to hide or a piece of vegetation. So pray she isn’t hungry if she lays eyes on you. And even if by some miracle she didn’t see you, she’d still smell you. 

If she decided you looked tasty, you probably wouldn’t hear her coming as much as you’d feel her. Modern science indicates that T. Rex didn’t roar like in Jurassic Park, but rather bellowed or maybe even hissed like crocodilians. If she were on to you, you’d most likely feel this sense of unease creep up your spine as a low-pitched rumble in the air permeated through you. You wouldn’t know what it was or where it was coming from until you hear her footfalls. By then it’s too late–you could try to run but she’d probably catch you. There’s plenty on YouTube that reconstructs what T. Rex may have sounded like, and it’s legitimately haunting.  

To wrap all of this up, the one bit of good that came out of the cursed year that is 2020 is that this wonderful child of science and art came into the world, and reaffirmed my respect and admiration for the eight ton slab of muscle and teeth that is this magnificent creature.

…and it is nothing if not magnificent.

TRAILER: “TIME MASTERS (LES MAÎTRES DU TEMPS)” (1982)

This animated science fiction feature film was directed by René Laloux and Tibor Hernádi but most notably - designed by the artist Mœbius. It is based on Stefan Wul’s 1958 science fiction novel L'Orphelin de Perdide (The Orphan of Perdide).

It’s about a boy, Piel, who is stranded on the desert planet Perdide, where giant killer hornets live. He awaits rescue by the space pilot Jaffar, the exiled prince Matton, his sister Belle and Jaffar’s old friend Silbad - who are all trying to reach Perdide and save Piel before it is too late.

If you’ve seen this film,  you’ve probably seen the English language dubs by the BBC in 1987 or 1991 called Time Masters.

This is a super rare film that you can find on DVD, but usually used, and pretty expensive.
