Ancient Egyptians drew the Milky Way on coffins and tombs, linking them to sky goddess, study finds
Starry paintings found on ancient Egyptian coffins and tombs indicate that the sky goddess Nut was closely associated with the Milky Way galaxy, according to a new study by an astronomer.
While Egyptologists have long believed Nut was connected with the Milky Way, this new study helps support the idea.
Or Graur, an associate professor of astrophysics at the University of Portsmouth in the U.K., examined 125 depictions of the goddess Nut (pronounced "Noot") on coffins and tomb walls that are up to 5,000 years old. A few of these paintings were unusual in their detail, Graur reported in a study published April 30 in the Journal of Astronomical History and Heritage.
In many depictions of Nut, the goddess is shown naked and arched over the sky, sometimes with stars and solar disks over her body. This posture shows her connection with the sky and her protection of Earth below, according to a statement from the University of Portsmouth. But the unusual paintings showed another aspect of her identity.
For instance, on the outermost coffin of a chantress (a person who performs religious prayers) named Nesitaudjatakhet, there is a depiction of Nut lying down. Her body is covered in stars, and there is "a thick, undulating black curve that bisects Nut's star-studded body and recalls the Great Rift that cleaves the Milky Way in two," Graur wrote in the study.
"I think that the undulating curve represents the Milky Way and could be a representation of the Great Rift — the dark band of dust that cuts through the Milky Way's bright band of diffused light," Graur said in the statement.

Graur noted that similar undulating waves appear along with images of Nut in the decorations of four tombs in the Valley of the Kings. For instance, the ceiling of Ramesses VI (who ruled circa 1143 to 1136 B.C.) has two back-to-back images of Nut that are "separated by thick, golden undulating curves that issue from the base of Nut's head and travel above her back all the way to her rear," Graur said.
The fact that some paintings depict Nut with these undulating waves suggests a close association with the Milky Way, Graur said. The ancient Egyptians may have believed that this association helped her protect the Earth, Graur wrote. Geb, an Egyptian god who represents the Earth, is sometimes seen underneath the arched Nut, he wrote in the study.

Nut was also associated with all other aspects of the day and night sky. "We should not think of the Milky Way as a representation of Nut," Graur wrote in the study. "Instead, we should think of the Milky Way as one more astronomical phenomenon that, like the stars and the Sun, are part of the sky and hence a part of Nut."
The finding is not new to Egyptologists, but it's important to have the same interpretation from an astronomer's point of view, said Rogério Sousa, a professor of Egyptology and ancient history at the University of Lisbon in Portugal.
"I can say that I agree with the identification between Nut and the Milky Way proposed by Or, which has always been implied by Egyptologists," Sousa told Live Science in an email. "But Or being an astronomer [gives it an] astronomical input."

Gene that differs between humans and Neanderthals could shed light on the species' disappearance, mouse study suggests
When you buy through links on our articles, Future and its syndication partners may earn a commission. A protein that helps synthesize DNA is different in modern humans than it is in Neanderthals and Denisovans — our closest extinct relatives — and new experiments in mice genetically modified to express the modern human version hint that this may have made us behave differently. That discovery, in turn, could shed light on why Neanderthals and Denisovans vanished, researchers propose in a new study. But the significance of the findings for humans is still unclear. "It's too early to translate these findings directly to humans, as the neural circuits of mice are vastly different," study lead author, Xiangchun Ju, a postdoctoral researcher at the Okinawa Institute of Science and Technology in Japan, said in a statement. However, this work hints that the variant seen in modern humans "might have given us some evolutionary advantage in particular tasks relative to ancestral humans," such as competing for scarce resources. Key protein Previous research found that modern humans diverged from their closest evolutionary relatives, Neanderthals and Denisovans, about 600,000 years ago. It's not clear why modern humans survived while our closest relatives died off. To search for potential genetic clues to solve this mystery, the researchers analyzed the enzyme ADSL (adenylosuccinate lyase). This protein helps synthesize purine, one of the fundamental building blocks of DNA and other vital molecules. Related: A braided stream, not a family tree: How new evidence upends our understanding of how humans evolved "There are a small number of enzymes that were affected by evolutionary changes in the ancestors of modern humans. ADSL is one of them," study co-author Svante Pääbo, Nobel laureate, leader of the human evolutionary genomics unit at the Okinawa Institute of Science and Technology in Japan, and director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, said in a statement. ADSL is made up of a chain of 484 amino acids. The version of this enzyme found in virtually all modern humans differs from that seen in both Neanderthals and Denisovans by just one amino acid — the 429th amino acid in ADSL is valine in modern humans but alanine in our extinct relatives. The scientists noted the ADSL mutation is seen in modern humans and not our closest extinct relatives, and so likely appeared after we separated from the lineage that led to Neanderthals and Denisovans. This led the researchers to investigate the possible behavioral effects of this mutation. Previous research on lab-grown cells found that the ADSL variant seen in modern humans resulted in a more unstable version of the enzyme that broke down more quickly compared to the one in Neanderthals and Denisovans. Behavior changes The new study, published Aug. 4 in the journal PNAS, similarly found that, in mice, the modern variant leads to higher levels of the chemicals that ADSL normally acts on to synthesize purine in several organs, especially the brain. This finding supported the idea that the modern human version of ADSL is less active than the variant seen in Neanderthals and Denisovans. In experiments where mice learned they could get a drink of water following specific lights or sounds, female mice genetically modified to possess a version of ADSL similar to the kind seen in modern humans were better at getting water than their littermates without this variant were. This might suggest the human-like variant made female mice better at learning to connect the dots between the water and the lights or sounds, or more motivated to seek out the water in some way. The changes in behavior and ADSL levels seen in female mice with the modern-human variant of the enzyme was not seen in male mice. "It's unclear why only female mice seemed to gain a competitive advantage," study co-author Izumi Fukunaga, a researcher at the Okinawa Institute of Science and Technology, said in a statement. "Behavior is complex." Statistical tests analyzing Neanderthal; Denisovan; and modern African, European and East Asian DNA found that mutations in the ASDL gene appeared in modern human genomes at higher rates than random variations over time would suggest, making it likely that these mutations provided some evolutionary advantage. Perhaps running counter to the new findings, prior work found that genetic disorders leading to ADSL deficiency in modern humans can lead to intellectual disability, speech and language impairment, and other problems. This suggests that during evolution, modern humans had to balance the potential benefits of reducing ADSL activity with the problems that could occur from ADSL deficiency, study co-author Shin-Yu Lee, also of the Okinawa Institute of Science and Technology, said in a statement. Implications unclear Not everyone thinks the study has direct implications for why modern humans thrived or for why Neanderthals or Denisovans disappeared. These results in mice "don't say too much about human evolution at this stage," Mark Collard, a paleoanthropologist at Simon Fraser University in Burnaby, British Columbia who did not take part in this research, told Live Science.

"I expect we'll see a cascade of studies like this one in the next few years." Future research can investigate the specific mechanisms by which changes in ADSL activity influence behavior. Scientists can also explore how changes in ADSL activity are associated with other behaviors and how multiple genetic changes might work in concert, the study authors wrote. Solve the daily Crossword

See a razor-thin crescent moon join Jupiter and Venus in the predawn sky on Aug. 20
When you buy through links on our articles, Future and its syndication partners may earn a commission. Look to the east in the hours preceding sunrise on Aug. 20 to see a thin crescent moon rendezvous with Venus and Jupiter to form a celestial triangle in the predawn sky. TOP TELESCOPE PICK Want to see the planets of the solar system for yourself? The Celestron NexStar 8SE is ideal for beginners wanting quality, reliable and quick views of celestial objects. For a more in-depth look at our Celestron NexStar 8SE review. The 9%-lit waning crescent moon can be found roughly 15 degrees above the eastern horizon an hour and a half before sunrise on Aug. 20, embedded in the twinkling stars of the constellation Gemini. Venus will be visible as a bright 'morning star' shining approximately 5 degrees to the lower right of the lunar disk, while Jupiter will sit less than 10 degrees to the upper right of the moon, forming the highest point of the cosmic triangle. Remember, the width of your fist held at arm's length accounts for roughly 10 degrees of night sky. The bright stars Castor and Pollux will be positioned to the left of the moon in the early morning hours of Aug. 19. Mercury, meanwhile, will be visible close to the horizon, but will swiftly become lost in the glare of the sun, which rises at 6:11 a.m. ET (1011 GMT) for viewers in New York. Viewing the cosmic trio with a 6-inch telescope will reveal the dark oval of the Grimaldi Basin impact site scarring the lunar surface, along with cloud bands on the surface of Jupiter, and the moon-like phases of Venus, under good atmospheric conditions. The coming nights will see the wafer-thin lunar crescent sweep past Venus to join Mercury and the Beehive open star cluster in the constellation Cancer, the crab, ahead of its new moon phase on Aug. 23.

Don't miss Mercury, the moon and the Beehive Cluster align in a special August morning sky show
When you buy through links on our articles, Future and its syndication partners may earn a commission. Isaac Asimov (1920-1992), a legendary writer of science and science fiction, once noted in "The Solar System and Back," that the planet Mercury is rarely visible when it is truly dark. "I suspect, in fact," he observed, "that many people today (when the horizon is generally much dirtier and the sky much hazier with the glare of artificial light than it was in centuries past) have never seen Mercury." In pre-Christian times, Mercury had two names, as it was not realized that it could alternately appear on one side of the sun and then the other. When visible in the evening sky, it was called Mercury and when appearing as a morning star, it was known as Apollo. It was Pythagoras, around the 5th century B.C., who first recognized that Mercury and Apollo were the same celestial body. A fine viewing window is now open Mercury is indeed clever at escaping detection. It is said that the astronomer Copernicus never saw the planet. Yet you can find it, if you know where to look. As the innermost planet, Mercury is usually masked by the sun's glare, so we must look for Mercury either soon after sunset, or in the case we are discussing here, just before sunrise. On the morning of Tuesday morning (Aug. 19), Mercury reaches its greatest western elongation, meaning it's at its maximum apparent distance from the sun. To catch a glimpse, set your alarm for 45 minutes before sunrise and look low toward the east-northeast horizon. First, you'll spot brilliant Venus. About one and a half fist‑widths (approximately 15°) lower left of Venus, look for a bright, yellowish point of light, Mercury. Skinny moon points the way on Thursday On Thursday morning (Aug. 21), besides Venus, there will be another celestial object to guide you to Mercury. That will be our moon. The moon will appear as a very slender sliver of light, only 4% illuminated and less than two days before the new phase. It will be positioned 5 degrees (half a fist) above Mercury. Binoculars will make things a bit easier to make a sighting, though sighting this very thin waning lunar crescent should be evident with the unaided eye. This morning Mercury will shine at magnitude -0.3. Among the stars, only Sirius and Canopus shine brighter, so once you locate the moon, sighting Mercury should be a relatively easy task. And although it swings back toward the sun after Aug. 18, it will continue to be visible until virtually the end of the month as it continues to brighten. By Aug. 28, it will have more than doubled in brightness, reaching a brilliant magnitude of -1. Beehive buzzes nearby TOP TELESCOPE PICK Want to view the night sky up close? The Celestron NexStar 8SE is ideal for beginners wanting quality, reliable and quick views of celestial objects. For a more in-depth look, check out our Celestron NexStar 8SE review. Besides viewing the moon and Mercury with binoculars on Aug. 21, there will be another celestial sight to look for that morning. Try looking for it when the twilight sky is not so bright, roughly an hour or more before sunrise. Located about 2 degrees below the hairline-thin moon will be M44, one of the sky's finest open clusters. Popularly known as the Beehive, it's also one of the nearest open clusters at a distance of 500 light-years. Binoculars are ideal for examining this wide, interesting star field. Its central group of stars is arranged into rough rows that form a generally triangular shape, suggesting an old-fashioned beehive. For centuries, M44 has also been known as Praesepe, Latin for "Manger." Pressing close to it are the two stars that supposedly represented the Northern and Southern Donkeys: Asellus Borealis and Australis.
