An unusual depiction of the ancient Egyptian sky goddess Nut may include a representation of the "Dark River" or "Great Rift"—the band along the Milky Way caused by dust clouds.
This is the conclusion of Professor Or Graur of the University of Portsmouth, England, who studies the multicultural mythology of the Milky Way. In a recently published study in the Journal of Astronomical History and Heritage, Graur analyzed over 100 images of Nut from 555 coffins dating back 5,000 years.
In many representations, Nut is imagined as a naked woman, often covered with stars or solar discs, arched over her brother, the Earth god Geb, invoking her association with the sky and protecting the Earth from chaos that lay beyond.
But something is different about how Nut was pictured on the outer coffin of the chantress Nesitaudjatakhet, who had been buried some 3,000 years ago. Cutting between the stars on her body weaves an undulating, black curve that runs from the tips of her toes to the tips of her fingers.

"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," said Graur, who added that the similarity was "stark," in a statement.
The astrophysicist notes that similar undulating curves can be seen in four tombs within the Valley of the Kings, the necropolis on the other side of the Nile from the modern city of Luxor.
"In the tomb of Ramesses VI, for example, the ceiling of the burial chamber is split between the Book of the Day and the Book of the Night," Graur said.
"Both include arched figures of Nut displayed back-to-back and 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."

The present study builds upon Graur's previous work on ancient Egyptian depictions of the Milky Way, which examined assorted sources, including both the Pyramid and Coffin Texts and the Book of Nut, in comparison with simulations of the night sky as it would have appeared in ancient times.
"I did not see a similar undulating curve in any of the other cosmological representations of Nut," said Graur.
"It is my view that the rarity of this curve reinforces the conclusion I reached in a study of ancient texts last year, which is that although there is a connection between Nut and the Milky Way, the two are not one and the same."
Instead, the astrophysicist believes that the Milky Way is a cosmological phenomenon, just like the sun and stars, that can appear along Nut's body in her role as the sky.

Scientists puzzled by giant planet detected orbiting tiny star
By Will Dunham WASHINGTON (Reuters) -Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star. The discovery defies current understanding of how planets form. The star is only about a fifth the mass of the sun. Stars this size should host small planets akin to Earth and Mars under the leading theories on planetary formation. But the one detected in orbit around this star is much larger - in fact, as big as Saturn, the second-largest planet in our solar system. The star, named TOI-6894, is located roughly 240 light-years from Earth in the constellation Leo. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). It is the smallest-known star to host a large planet, about 40% smaller than the two previous record holders. "The question of how such a small star can host such a large planet is one that this discovery raises - and we are yet to answer," said astronomer Edward Bryant of the University of Warwick in England, lead author of the study published on Wednesday in the journal Nature Astronomy. Planets beyond our solar system are called exoplanets. The one orbiting TOI-6894 is a gas giant, like Saturn and Jupiter in our solar system, rather than a rocky planet like Earth. The birth of a planetary system begins with a large cloud of gas and dust - called a molecular cloud - that collapses under its own gravity to form a central star. Leftover material spinning around the star in what is called a protoplanetary disk forms planets. Smaller clouds yield smaller stars, and smaller disks contain less material to form planets. "In small clouds of dust and gas, it's hard to build a giant planet," said exoplanet scientist and study co-author Vincent Van Eylen of University College London's Mullard Space Science Laboratory. "This is because to build a giant planet, you need to quickly build a large planet core and then quickly accrete (accumulate) a lot of gas on top of that core. But there's only so much time to do it before the star starts shining and the disk rapidly disappears. In small stars, we think there's simply not enough mass available to build a giant planet quickly enough before the disk disappears," Van Eylen added. No known planet is larger than its host star, and that is the case here as well, though the two are much closer in size than usual. While the sun's diameter is 10 times larger than our solar system's largest planet Jupiter, TOI-6894's diameter is just 2.5 times greater than its only known planet. The star is a red dwarf, the smallest type of regular star and the most common kind found in the Milky Way galaxy. "Given these stars are very common, there may be many more giant planets in the galaxy than we thought," Bryant said. The star is about 21% the mass of the sun and much dimmer. In fact, the sun is about 250 times more luminous than TOI-6894. "These findings suggest that even the smallest stars in the universe can in some cases form very large planets. That forces us to rethink some of our planet formation models," Van Eylen said. The planet is located about 40 times closer to its star than Earth is to the sun, completing an orbit in approximately three days. Its proximity to the star means the planet's surface is quite hot, though not as hot as gas giants called "hot Jupiters" detected orbiting similarly close to bigger stars. Its diameter is slightly larger than Saturn and a bit smaller than Jupiter, though it is less dense than them. Its mass is 56% that of Saturn and 17% that of Jupiter. The main data used in studying the planet came from NASA's orbiting Transiting Exoplanet Survey Satellite, or TESS, and the European Southern Observatory's Chile-based Very Large Telescope, or VLT. The researchers hope to better understand the planet's composition with observations planned over the next year using the James Webb Space Telescope. "We expect it to have a massive core surrounded by a gaseous envelope made up of predominantly hydrogen and helium gas," Bryant said.

60 years ago, Ed White went out for walk
When you buy through links on our articles, Future and its syndication partners may earn a commission. On this day (June 3) 60 years ago, a NASA astronaut stepped outside his Gemini spacecraft and made history as the first American to perform an extavehicular activity (EVA), or spacewalk. NASA astronaut Edward H. White II left his Gemini 4 capsule and crew mate Jim McDivitt for a 20-minute spacewalk on June 3, 1965. It was only the second extravehicular activity (EVA) ever made (the first was by Soviet-era cosmonaut Alexei Leonov a few months earlier) and the first by an American. White brought with him a camera and a small jet pack; the latter did not work very well. He was connected to his spacecraft by an umbilical. Gemini 4 entered an orbit about Earth between 103 and 180 miles (165 and 289 kilometers) in altitude. During the spacewalk, White was in radio contact with ground controllers in Hawaii and Houston. There are other, better-composed photos of White on the same historic spacewalk, but this one can be used to illustrate one of, if not the most important lesson NASA learned from his EVA: They did not know how yet to spacewalk. White floated well enough, but he had no real control of his movements, even with a prototype handheld jet pack. There were no handrails for him to use on the outside of the Gemini capsule, and he had not trained in neutral buoyancy underwater — the best analog for the conditions in the vacuum of space. Still, even with the troubles he encountered, White called the end of his EVA the "saddest moment" of his life. You can read more about the history and basics of spacewalking and learn more about Ed White's Gemini 4 EVA.
