Africa’s Oldest Cremation

Earlier this year, archaeologists were perplexed when they unearthed the world’s earliest intentional cremation of an adult human. The discovery in Malawi raised questions about early funeral rituals. At the base of a granite hill that is several hundred feet is the Hora 1 archaeological site, which has been known for decades.

This is where scientists unearthed prehistoric ash about the size of a queen bed that contained remains of a woman just under 5 feet tall. This find had been sheltered from rain and such for thousands of years, which allowed for good preservation of bones.

The ash had been cemented together, not by rain, but by soil moisture. It was hard to excavate, but helped protect the bones.

Before now, the oldest known deliberate cremations were dated to roughly 3,300 years ago. This cremation at Hora 1 was a meticulously planned event performed 9,500 years ago by hunter-gatherers.

From this time period, there haven’t been very many burned bodies discovered. And why this person? How was she significant? Nobody knows yet.

Studying prehistoric funeral rituals offers insights into how people treated each other in life.

The small adult female’s remains bear marks of manipulation, so her body was cremated prior to decomposition. This indicates that these ancient hunter-gatherers undertook elaborate mortuary practices. These complex mortuary and ritual activities predate food production activities, which challenge assumptions about community cooperation and memory-making in such societies.

Although burned human remains have been found dating to about 40,000 years ago in Australia. Intentionally built pyres of fuel don’t appear in archaeological records until 10,000 years ago.

Cremation is more common among food-producing societies. The practice is very rare among hunter-gatherers, both ancient and modern. Pyres require a huge amount of labor, time, and fuel.

The pyre at Hora 1 would have required gathering at least 30 kg of deadwood and grass, a significant commitment. The blaze likely reached temperatures greater than 500C.

The finding sparks a re-think about hunter-gatherer communities. It also questions the change in mortuary practices in Malawi 9,500 years ago. These people had typically buried the dead.

Researchers found that the society revisited the location and built more large fires, indicating they had a longer tradition based on their shared memory of the woman’s cremation. That other deaths at the site were buried and not cremated indicate that this death was special.

Found: A Rogue Planet

Scientists have spotted a ‘rogue planet’. Just what is a rogue planet, you might ask? It’s a planet that is floating on its own through space. It doesn’t orbit a star, nor is it part of a stellar system. It’s just bopping along through space without any companions of any kind. It would be nice if it had a moon or two keeping it company, but I didn’t find any mention of that possibility.

Also known as free-floating planets, rogue planets are mysterious because they are much less bright than other planets—the kind that do belong to a stellar system. A key way to detect planets is to spot them when they move in front of their star. But without a star, planets are much harder to see.

Scientists spotted this rogue using a micro-lensing event, which is when the gravity from an object magnifies the light from a star located behind it. That effect was seen from both ground- and space-based telescopes. Astronomers compared the different positions in order to work out the mass of the planet. It is roughly 22% the mass of Jupiter and it is located around 3,000 parsecs from the Milky Way’s center. (A parsec is about 3.26 light-years of distance.)

The planet’s mass indicates it probably formed in a planetary system, but it has since broken free. It is thought that lower mass rogue planets may be thrown out into space by big gravitational changes in their system, which might happen by interactions with nearby planets or unstable stars.

There have only been a small number of rogue planets found so far. The number is expected to increase, particularly through the launch of Nasa’s Nancy Grace Roman Space Telescope.

I wonder if any of these rogue planets ever find a new home in a new stellar system?
