Archaeologists discover intact Roman chariot near the ancient Roman city of Pompeii.

We know what Roman chariots looked like from the many painting and drawings that exist from the Roman era. But last month, archaeologists discovered a new intact Roman chariot buried in the ground near the ancient city of Pompeii. Pompeii was a large, wealthy city near Naples, Italy that was unexpectedly buried under a layer of thick volcanic ash and pumice from the eruption of Mount Vesuvius in AD 79. The eruption caught many of the city's inhabitants off-guard. Those that were trapped in the city were buried under about 15 feet of ash which preserved many of the buildings - and bodies of those who died there. When archaeologists began digging in the area during the 1960's, they found a city that was virtually frozen

Wow! Check out NASA’s high-res video of Perseverance parachute/rocket landing on Mars.

Perseverance's landing sequence was anything but easy. The landing involved several steps, each of which had to be executed perfectly for a safe landing - and the geeks at NASA nailed it! Here is a video breakdown of the landing. Here are the steps it took to land Perseverance on Mars.

How many black holes does it take to fill a galaxy? Apparently a lot more than we thought.

See the "stars" in the picture above. Well, those aren't stars. They're supermassive black holes. Black holes don't generate much radiation and thus, are difficult for astronomers to spot. However, as they devour everything around it, materials spiral into the black hole like water spinning around a drain. This action generates radio waves which scientist can use to detect the presence of a black hole. The detailed map of black holes was created by astronomers using the low radio frequency signatures detected by the LOw Frequency ARray (LOFAR) in Europe. The LOFAR array consists of about 20,000 radio antennas distributed across 52 different locations in Europe. Scientists wrote a special program that uses the LOFAR radio telescope data to map out the black holes we see in the

What are all those tiny little elf-doors scattered throughout the U.S. Capitol?

When you visit the U.S. Capitol building in Washington, D.C. try not to get too caught up in the splendor and instead, look down. Chances are you'll see a tiny little elf-door somewhere along the wall. In fact, they are scattered throughout the U.S. Capitol building but most visitors never notice them. The tiny doors serve as more than just a conversation piece or humorous Reeko's Mad Scientist Lab article. At one time, they served an important function. But we have to look way back in time to understand how those tiny little doors kept the Capitol building safe. The Christmas Eve Capitol fire On Christmas Eve in 1851, a guard (John Jones) was making his rounds through the Capitol building when he noticed a flicker of light

4-year-old girl walking on beach discovers UK’s most perfectly preserved dinosaur footprint.

"Daddy, what's this?" 4-year-old Lily Wilder from Barry, South Wales, UK took her first step as a scientist this week when she spotted a perfectly preserved dinosaur footprint while walking on the beach. The print measures about 10cm. Scientists believe it was made by a dinosaur about 75cm tall and is about 220 millions years old. The dinosaur species is unknown. Cindy Howells, the Paleontology Curator at Amgueddfa Cymru-National Museum said: "This fossilized dinosaur footprint from 220 million years ago is one of the best-preserved examples from anywhere in the UK and will really aid paleontologists to get a better idea about how these early dinosaurs walked. Its acquisition by the museum is mainly thanks to Lily and her family who first spotted it."

Meet the newly-discovered “nano-chameleon”, the world’s smallest lizard is no bigger than a fly.

A new species of chameleon has been discovered on the island of Madagascar. Known as Brookesia nana, or nano-chemeleon, the tiny male lizard measures only 9mm or 19mm if you include the tail. For comparison, a normal housefly measures about 7mm. The female of the species is larger at 29mm (including the tail). Researchers confirmed the specimens were not juveniles - the female had two eggs inside of her. It is believed the species may be so small due to the "island effect". Animals trapped on small isolated islands tend to evolve smaller bodies.

Yes! Scientists finally discover how Wombats poop square cubes.

It's a question that's kept Reeko up at night A mystic scientific anomaly with no rational explanation. Those cute little Wombats, the short-legged marsupials that are native to Australia, poop the most curious scat (i.e. feces or, ahem, turds). Despite having a normal round anus, Wombats poop square cubes! And Wombats don't waste their unique talent either. They poop between 80 and 100 one-inch pieces of square feces a day, about 4-8 pieces with each bowel movement. And since they only poop at night, scientist rarely witness the magnificent event. Thus, we have never quite understood how the physics of Wombat poop works. To solve the mystery, scientists dissected a dead wombat that had been hit by a car. [Editor's note: Hit by a car? Really? Are

Geologist breaks open Agate rock to find – Cookie Monster!

The inside of an Agate stone found in the Rio Grande do Sul region of Brazil, surprised its finder because of its eerie resemblance to popular Cookie Monster character. Its owner, gemologist Lucas Fassari estimates the unusual gem is worth about $10,000. "This is probably the most perfect Cookie Monster out there." The Agate stone contains brilliant blue quartz crystals with the wide eyes and big smile of the beloved Cookie Monster character from Sesame Street. Agate is an often-colorful, banded volcanic rock formation consisting of chalcedony and quartz as its primary components. Agate minerals tend to from within pre-existing hollow rock. The cavity inside the hollow rock are caused by gases trapped inside the liquid volcanic material before the rock hardens. These cavities are then filled with

Baby tyrannosaur fossil finally confirms what scientists thought all along – baby T. rex was about the size of a dog.

A team of scientists recently unearthed the fossilized remains of a tiny jaw bone and claw in the United States. 3D scans of the fragments revealed they belonged to tyrannosaurs - the cousins of T. rex. Based on the size of the fossils, it is believed a baby tyrannosaurs would measure about 3-feet long when they hatched - about the size of a Border Collie dog. The findings suggest a tyrannosaurs eggs would measure around 17 inches long. No tyrannosaur dinosaur eggs have ever been found. Tyrannosaurs lived more than 70-million years ago. There are many types of tyrannosaurs including the popular Tyrannosaurus rex. They had large skulls, foreword facing eyes, and humorously short arms.

Astronomers spot six-star system in Milky Way – meet TIC 168789840.

A three-star system Astronomers at NASA have discovered a unique six-star system located about 2,000 light-years from Earth. The system, TIC 168789840, has 3-pairs of stars whirling about each other. The stars in TIC 168789840 are too far from Earth to be seen clearly through a telescope so scientists used a bit of astronomy-magic to spot them. The stars orbit on a plane that lines up perfectly with Earth. Due to the convenient alignment, every time one of the stars passes another, an eclipse is created which causes a ebb and flow of light when viewed from Earth. Scientists could then use years of observational data to look for cycles of dimming and lighting and then determine the dimming was caused by a pair of stars rotating
