Space junk is out of control, scientists say

by Sean McLachlan on

It’s a dilemma faced by every adventure traveler: to find the perfect remote spot untouched by modernity, free from cell phones, television, and trash. Of course there is no such place, not even in space. In fact, the orbital detritus of modern life can be downright dangerous, scientists warn.

A new report from the National Research Council says there are so many bits of trash in orbit, ranging from defunct satellites to fragments like nuts and bolts, that they’re bumping into each other, breaking apart, and making more trash. Around 22,000 large pieces of space junk are tracked from the ground, occasionally prompting the International Space Station to maneuver out of the way, and there are hundreds of thousands of more pieces too small to be detected. It amounts to a cloud of trash surrounding the earth, as this NASA image shows.

This puts current astronauts and future space tourists in peril. With the high velocities objects achieve in orbit, it’s like having hundreds of thousands of bullets flying around the Earth.

And it’s getting worse. The BBC reports two satellites crashed in 2009 and broke apart. Also, the Chinese tested a satellite killer in 2007 that successfully smashed up its target into more than 150,000 pieces larger than a centimeter. The U.S. and Soviet Union tested similar weapons back in the 1960s and 1970s, creating their own clouds of debris.

Several manned spacecraft have been hit by space debris. Two Shuttle missions have had radiator panels in the cargo bay punctured by debris. The International Space Station and Mir have both suffered numerous impacts. Sometimes the damage is caused by natural micrometeorites.

One certain impact by space debris was in 1983 when a fleck of paint smacked into the space shuttle Challenger’s front window and left a crater, as you can see in this NASA image.

If a fleck of paint can do this to the Space Shuttle, imagine what an old rocket booster could do.

Ancient palace discovered in Sudan

by Sean McLachlan on


Archaeologists digging in the ancient city of Meroë in the Sudan have discovered what they believe is a palace dating to 900 BC.

The team discovered the building under the remains of a later palace. It’s believed to be the oldest building yet discovered at the site, which was once the capital of the Kingdom of Kush. Kush had several great cities and exported iron all the way to China. From 747-656 BC, the Kushites ruled Egypt as the twenty-fifth dynasty. The empire lasted from about 1000 BC to 350 AD before being conquered by the Empire of Axum in Ethiopia.

Meroë is one of the greatest archaeological sites in Africa. It has more than 200 pyramids, although they’re smaller than the largest Egyptian pyramids.

For a long time Meroë and Kush were understudied in favor of the more famous Egyptian civilization. Now scholars are beginning to realize that this Sudanese civilization contributed a lot to Egyptian culture.

Meroë is two-and-a-half hours north of Khartoum and it’s feasable to do in a long day trip. If you’re not going to the Sudan, the British Museum in London has a whole room dedicated to this civilization and its art.

Roman bath discovered in York

by Sean McLachlan on


The remains of a Roman bath have been discovered in York in northern England.

Archaeologists made the find while excavating ahead of construction of the new City of York Council Headquarters. York (then called Eboracum) was an important trading center in Roman times. So important, in fact, that it had more than one bath. The image above is from the basement of the Roman Bath pub, where a small museum shows off the remains of another bath.

Based on coins and pottery found at the site, the newly discovered bath dates from the late second and early third centuries AD. The site will be open to the public for free this weekend.

Unlike many Roman cities, York continued to be important mercantile and religious center in the later Anglo-Saxon and Viking periods. The Yorkshire Museum exhibits a huge collection of Viking artifacts from an earlier excavation.

Public bathhouses were very popular in Roman culture. They included cold, warm, and hot pools and places for relaxation and socializing. The best preserved example is at the appropriately named city of Bath, an easy day trip from London.

New discoveries reveal life and times of the Roman Emperor Hadrian

by Sean McLachlan on

The Emperor Hadrian is one of Rome’s most famous emperors, ruling at the height of the Empire from 117-138 AD. His villa just north of Rome is a popular tourist attraction, yet some Italian researchers have discovered what countless visitors never noticed: the buildings are aligned with astronomical events.

On the summer solstice (June 21 this year) light passes through an opening above a doorway and shines on a niche in the opposite wall. The niche probably contained the statue of some deity. This sort of light effect has been found in other ancient sites. Another building is aligned both to the summer and winter (December 21 this year) solstices, during which the light shines through a row of doors.

The effects may have been part of the worship of Isis. Originally an Egyptian goddess, a popular mystery religion grew up around her in the Roman Empire.

Hadrian’s other famous monument, Hadrian’s Wall, is also the site of a recent discovery. At the fort of Vindolanda, dozens of circular huts have been discovered that don’t look like anything the Romans built. In fact, they look like the huts of the tribes living north of the wall in Scotland, outside the direct influence of the Roman Empire. These may have been homes for refugees from friendly tribes fleeing common enemies, perhaps during the invasion of Scotland by Emperor Septimius Severus (ruled 193-211 AD) or the homes of temporary workers who lived along the wall and served the Romans.

Five places to see shrunken heads

by Sean McLachlan on


Call me sick, but I’ve always been fascinated with shrunken heads.

“OK, you’re sick!”

Fine, but you’re still reading this, aren’t you?

Throughout history many cultures took heads as trophies, including the ancestors of many Gadling readers–the Celts. Celtic warriors used to cut the heads off of enemies and attach them to their chariots to look extra intimidating in battle. Japanese samurai, Maori warriors, and angry peasants in the French Revolution all took enemy heads as trophies.

Yet only one culture, the Jivaro of South America, actually shrank heads. Living in the Amazon rainforest of Ecuador and Peru, the Jivaro people developed the strange custom of cutting off an enemy’s head and shrinking it down to the size of a man’s fist. Called tsantsa, these shrunken heads served not only as proof of a warrior’s valor but also as a way to destroy the victim’s spirit, which might otherwise take revenge.

The process was gruesome but simple. Different sources give different recipes. This one comes from the well-researched site Head Hunter. Once you get a head, cut open the back so the skin and hair can be peeled from the skull. Throw the skull into a river as an offering to the anaconda. Sew the eyes shut, and close the mouth with wooden spikes or thorns. Boil the head for no more than two hours, then turn the skin inside out to clean off any nasty residue. Turn the skin right side out and sew up the slit you cut in the back.

%Gallery-126587%To shrink further, drop hot stones through the neck hole. Roll them around to ensure even heating and prevent any unsightly burn marks. The head will continue to shrink until the neck hole is too small to allow stones to enter. Now use hot sand to shrink the head even more. Press hot stones against the face to singe off any excess hair and shape the face to look nice, and use a hot machete to dry the lips, which will not have shrunk as much as the rest of the head.

Now put three chonta, or palm thorns, through the lips and tie them together with long, decorative string. Hang it over a fire to harden. You may also want to blacken the skin with charcoal to avoid the man’s spirit from seeing out. Pierce a hole through the top of the head so you can put a string through and wear your trophy around your neck.

The whole process takes about a week but with a bit of patience and practice, you’ll have a keepsake of your favorite battle and a surefire icebreaker at parties.

Shrunken heads fascinated early European explorers. They became a hot commodity and warfare increased in order to meet the demand. Often tribesmen found it easier and safer to make a fake head by using an animal head or making one out of leather. Some researchers estimate that up to 80% of all heads on display in museums are actually fake. This week a study was released of a DNA analysis of a shrunken head in an Israeli museum that turned out to be genuine. Researchers are hoping to test more heads to determine if they’re legit.

Some fake heads are actually real, in a sense. When a warrior killed an enemy but couldn’t get the head for whatever reason, or killed an enemy who was a blood relative and therefore wasn’t allowed to take the head, he could make a head from that of a sloth as a stand-in. Magically this was considered a real tsantsa.

Controversy over displaying human remains and the demands by some tribes to have them back has meant that many museums have removed their displays of shrunken heads. So where can you still see these little darlings?

Ripley’s Believe it or Not Museum, Williamsburg, Virginia. This branch of Ripley’s fun chain of museums has several shrunken heads on display.

Ye Olde Curiosity Shop, Seattle, Washington. Forget the Space Needle, this is the coolest attraction in Seattle. Once you’ve seen the real shrunken heads, head over the the gift shop to buy a cruelty-free replica.

Lightner Museum, Saint Augustine, Florida. This huge collection of nineteenth century bric-a-brac housed in an old mansion is an odd place to find a shrunken head collection, but people collected all sorts of things back then.

Pitt-Rivers Museum, Oxford, England. Britain’s favorite museum has artifacts from all the world’s cultures, including a display case full of shrunken heads and trophy heads.

Madrid, Spain. Get a double dose of headhunting here at the Museo de América and the Museo Nacional de Antropología.
