Individuals each fashionable and historical have lengthy recognized of the Pleiades, or Seven Sisters, a small assortment of stars within the constellation Taurus.
However this well-known meeting may level the best way to the world’s oldest story, one informed by our ancestors in Africa practically 100,000 years in the past, a speculative new examine has proposed. To make this case, the paper’s authors draw on similarities between Greek and Indigenous Australian myths in regards to the constellation. However one skilled informed Stay Science that similarities in these myths might be pure likelihood, not an indication they emerged from a standard origin.

The Pleiades are a part of what astronomers name an open star cluster, a gaggle of stars all born across the identical time. Telescopes have recognized greater than 800 stars within the area, although most people can spot solely about six on a transparent, darkish night time.
But cultures around the globe have typically referred to this constellation with the quantity seven, calling them the “Seven Sisters,” “Seven Maidens” or “Seven Little Women.” This head scratcher has puzzled many scientists, akin to astrophysicist Ray Norris of Western Sydney College and Commonwealth Scientific and Industrial Analysis Organisation (CSIRO) Astronomy and Area Science in Australia.
Norris has labored with Indigenous Australians and discovered lots of their sky tales, together with these of various teams who establish the Pleiades as seven ladies being chased by the constellation Orion, who’s a hunter in these tales. This storyline is extraordinarily just like the one in historical Greek legends about these constellations.
“I’ve at all times thought, ‘Oh that’s actually bizarre,'” Norris informed Stay Science.
The case is not completely stunning, provided that each Orion and the Pleiades are vibrant and outstanding celestial options, and that Earth‘s rotation makes it look to us like the previous is chasing the latter throughout the night time sky. Some researchers have tried to elucidate the narrative resemblance by means of easy cultural change, stated Norris, provided that Europeans arrived in Australia greater than two centuries in the past. However such a timescale is just not lengthy sufficient for the story to have turn out to be so deeply embedded throughout completely different, far-flung Australian cultures, he added.

Norris famous that one of many Seven Sisters — a star generally known as Pleione — is usually misplaced within the glare of a close-by star referred to as Atlas, making it invisible to most human eyes. However 100,000 years in the past, when people have been first rising from the African continent and spreading over the world, the 2 stars would have been extra separated within the night time sky, maybe accounting for why the Pleiades are named for seven beings in lots of tales. In different phrases — our ancestors who had not but left Africa first got here up with the story, then carried this story in regards to the night time sky with them as they migrated to Europe, throughout Asia, and ultimately to Australia.
“You’ve got obtained these two bits of circumstantial proof,” stated Norris. “Collectively they make an fascinating speculation.” Together with a co-author, he posted a paper Jan. 25 about this chance to the pre-print database arXiv. Their examine has been accepted to, however not but printed in, a peer-reviewed journal.
Whereas noting that it is a “enjoyable and evocative thought,” astronomer and archaeo-historian Bradley Schaefer of Louisiana State College in Baton Rouge, who was not concerned within the work, didn’t assume the reason doubtless.
“People are people,” so they’ll populate the sky with female and male figures. By likelihood alone, about half the time, you’ll count on a given constellation to be related to males, and half the time with girls. Which implies that “about one-quarter of that point, Orion might be masculine and the Pleiades might be feminine,” Schaefer stated.
Given the massive variety of conventional tales, easy coincidences between any given two cultures are more likely to crop up, Schaefer stated. He additionally identified that the Norris paper used outdated stellar positioning data to mannequin the space between Pleione and Atlas 100,000 years in the past. The proper knowledge locations them two instances nearer throughout this epoch, which means there wouldn’t be a lot vital change in how the constellation appeared to our ancestors.
Norris’ paper doesn’t completely hinge on this truth, mentioning that the celebrities within the Pleiades are thought to fluctuate with brightness, and maybe 100,000 years in the past one of many very faint stars was way more seen, although nobody is aware of how a lot these stars fluctuate in brightness over the long-term.
It’s attainable the speculation is right, Schaefer stated, however the accessible proof is not very convincing. It gives a “lesson of what it takes to show one thing like this,” he added.
He gave as a counterexample the Massive Dipper, one other well-known constellation, that cultures throughout Eurasia describe as a bear. On this case, proof suggests a minimum of some tales in regards to the Massive Dipper doubtless did emerge from a standard origin story, he stated.
As an example, in a big variety of these, the “ladle” of the Dipper is given because the physique of the bear, and the three stars of the “deal with” are recognized as its tail (although bears do not have lengthy tails.)
But in lots of the conventional tales of Siberian folks in Jap Russia, the place folks additionally acknowledge the Massive Dipper as a bear, there may be an alteration. The ladle remains to be the bear’s physique, however the three stars of the deal with are branded as three hunters chasing the bear. Mizar, the central star of the deal with, has a small faint companion generally known as Alcor, and within the Siberian tales Alcor is a chicken serving to lead the hunters to the bear, Schaefer stated.
A big variety of Native American tales, informed by peoples unfold throughout the North American continent north of the Rio Grande, have a really related setup for the Massive Dipper — together with the bear, hunters and steering chicken, he added. On condition that an excessive amount of different proof reveals that people migrated over an historical land bridge within the Bering Strait between modern-day Russia and Alaska hundreds of years in the past, Schaefer thought it was more likely that these Massive Dipper tales share a standard origin.
Even this rationalization is just not universally accepted by archeo-historians, he added. However the many shared “traits imply that it’s an evocative, enjoyable, and sure true story,” he stated. It won’t be the titanic 100,000-year prompt timespan of Orion and the Pleiades, however having a story that’s a minimum of 14,000 years outdated remains to be fairly spectacular, Schaefer stated.
“That makes the Nice Bear the oldest mental property of humanity,” he stated.
