A large ancient Egyptian fortress in the northern Sinai Desert had an elaborate landscape of 500 trees leading to its entrance more than 2,000 years ago, new excavations reveal.
Archaeologists made the finding while uncovering more of a fortress that was rebuilt and modified over several centuries. The existence of the fortress has been known for decades. However, new finds by archaeologists from Egypt's Ministry of Tourism and Antiquities shed light on what the fortress was like more than two millennia ago.
Located at the site of Tell Abu Saifi, the fortress was in use during the Ptolemaic period (circa 304 to 30 B.C.), when Ptolemy I — a general of Alexander the Great — and his descendants ruled Egypt, and the Roman period (circa 30 B.C. to A.D. 642), when Egypt was a province in the Roman Empire .
They found that during the Ptolemaic period, there were 500 planting circles surrounded with clay on both sides of a road that led to the entrance of the fortress. These would have contained trees, the ministry said in a translated statement . It's not clear what exactly the climate was like in the Sinai Desert around 2,000 years ago.
They also found that, during Ptolemaic times, the fortress was surrounded by a trench (a moat) that was more than 6.6 feet (2 meters) deep. This trench would have helped soldiers defend the fortress. The Ptolemies faced a number of adversaries at different times, including the Seleucid Empire, the Roman Republic and rebel groups operating in Egypt.

The fortress was in use for centuries and was rebuilt and renovated over time.
The planting circles are an interesting find, Elizabeth Macaulay , a classics professor at the City University of New York Graduate Center who was not involved in the excavation, told Live Science in an email.
"It is certainly possible that clay planting circles could have been used to plant trees," Macaulay said. "500 trees would have been a lot, but we have evidence from papyri and archaeology for the large-scale cultivation of plants — vines, fruits, trees — in Ptolemaic Egypt." She noted that if the excavation team uncovers the remains of roots, it would help confirm that these circles were used for planting. It might also allow for the identification of the tree species.

The archaeologists made several other finds, including living quarters of soldiers and perhaps their families. In addition, they unearthed a stretch of road that was 328 feet (100 m) long, 36 feet (11 m) wide, and paved with limestone slabs. It would have been used for military units traveling to the fortress.
In an unexpected finding, archaeologists unearthed four corners of a structure that may be from an even earlier period. It's possible that this structure is also a fortress, but the team has not been able to date it or verify its purpose.
Live Science contacted the archaeologists who excavated the site but did not hear back by the time of publication.

August Moon: Here's what to look for during all 4 major moon phases
When you buy through links on our articles, Future and its syndication partners may earn a commission. The ever-shifting phases of Earth's moon present a wealth of targets for amateur astronomers to explore, ranging from magnificent craters and lunar seas to strange visual phenomena created as sunlight plays across the ancient surface, forming familiar shapes where none should be. So, grab your telescope and join us on a short, guided "road trip" of August's moon, in which we'll highlight a series of stunning targets to explore during each moon phase. Any backyard telescope will allow you to pick out the targets on our list, though a scope with an aperture of 6 inches or more will help reveal more detail across ancient lunar landscapes. Be sure to check out our roundups of the best telescopes and binoculars for exploring the solar system if you find yourself wanting a closer look at Earth's natural satellite. The first quarter moon (Aug. 1) The nights following each new moon phase will see the line separating night from day on the lunar surface creep inexorably westward. By Aug. 1, this line of demarcation — known as the terminator — will divide the lunar surface in two, heralding the onset of the moon's "first quarter phase." During this phase, the moon will already be high in the sky at sunset, with its right side fully lit and its left hidden under a veil of shadow. The nights leading up to Aug. 1 present a perfect opportunity to search for the historic Apollo 11 landing site on the southwestern shore of Mare Tranquilitatis (Latin for the Sea of Tranquility), from where Neil Armstrong announced "the Eagle has landed" on July 20, 1969. Mare Tranquilitatis is easily visible to the naked eye as a dark basaltic plain close to the equator to the right of the terminator, as indicated on the graphic below. A 6-inch telescope will help you zero in on the landing zone — known as Tranquility Base — by looking to the lower right of the prominent Ritter and Sabine craters, which can be found on the western edge of the lunar mare. Two nights later, on Aug. 4, the moon's terminator will fall slightly to the west of the Sinus Iridum impact basin, causing a brilliant "Golden Handle' to appear in the northwest region of the lunar surface. This striking effect occurs when the sun's rays pick out the peaks of the Montes Jura mountain range on the northern edge of Mare Imbrium. The full "Sturgeon Moon" (Aug. 9) By Aug. 9, the relentless westward march of the terminator will have swept across the entirety of the lunar surface, setting the stage for the full "Sturgeon Moon" to slip above the horizon at sunset, local time. The Sturgeon Moon is named for the time of year when the titular fish are most readily caught; it presents a good opportunity to observe the mighty form of Tycho crater extending its influence over the lunar disk. Tycho is easily visible to the naked eye, thanks in part to the vast streaks (or rays) of reflective material cast outward across the lunar surface in the wake of the brutal asteroid impact that created the 53-mile-wide (85-kilometer) crater. Every one of the moon's larger impact sites would have once played host to a bright ray system like Tycho, though exposure to the harsh space environment has since caused many to fade. After all, Tycho formed a mere 108 million years ago, while other lunar craters have been estimated to be 3.9 billion years of age. The August full moon also presents a great time to learn the locations of the many lunar mare (Latin for "seas") that can be spotted with the naked eye as the surface of Earth's natural satellite darkens. Each of the mare visible today were created billions of years ago, when lava flows filled the network of lunar craters carved out by powerful asteroid strikes. The lava lakes swiftly hardened to "repave" the moon, forming enormous basaltic plains that can be explored without the need for a telescope or binoculars. Mare Crisium can be spotted as a dark oval to the northeast of the lunar surface, while Mare Tranquillitatis (the Sea of Tranquility) — which plays host to the Apollo 11 landing site — is located to its left, bordered to the north by Mare Serenitatis (the Sea of Serenity). The equatorial region to the westward side of the lunar disk is dominated by Oceanus Procellarum (the Ocean of Storms), with Mare Imbrium (the Sea of Showers) to the north and Mare Nubium (the Sea of Clouds) to the south. The third quarter moon (Aug. 16) The passing of the full moon will see the terminator return to sweep over the eastern limb of the lunar surface until, finally, on Aug. 16, the third quarter moon will rise, with its right half bathed in shadow and its left illuminated by direct sunlight. Aug. 16 is a great opportunity to observe a dramatic display of light and shadow play across the terminator and to hunt down a pair of massive craters named to honor two legendary ancient Greek philosophers, inventors and astronomers: Plato and Archimedes. Look for the 62-mile-wide (10 km) Plato Crater just below the narrow form of Mare Frigoris soon after the moon rises around midnight on Aug. 16. Then, follow the terminator south to find the similarly sized Archimedes impact site above the pronounced sweep of the Montes Apenninus mountain range. The following night (Aug. 17) is a wonderful time to see the Copernicus and Kepler craters brightening Oceanus Procellarum. Both impact sites are surrounded by bright ejecta rays, albeit less pronounced than those exhibited by Tycho further to the south. The Copernicus Crater looks particularly impressive around this time, with its westward rim and central peak cast into relief by the oblique angle of the sun. Copernicus had been proposed as a candidate landing site for the Apollo 18 crewed lunar mission, though the program was cancelled long before its scheduled launch date due to budget constraints. New moon (August 23) During the new moon phase, the lunar disk lurks unseen in the daytime sky, leaving the night unblemished by the glare of reflected sunlight. Head away from city lights around this time to hunt the glowing band of the Milky Way's core, which can be spotted during the summer months streaming towards the eastern horizon as dusk gives way to night in dark sky locations. The moon will appear as a slim waning or waxing crescent on a handful of nights before and after the new moon phase, during which you may see the shadow-veiled expanse of the lunar surface infused with a soft glow. This phenomenon, known as "Earthshine," or the "Da Vinci Glow," occurs when the moon is positioned roughly between our planet and the sun, at which point sunlight reflected off Earth's surface bathes the unlit lunar disk in a subtle glow.

Earth, Mars, Venus — and a long-lost planet — may have once 'waltzed' in perfect harmony around the sun
When you buy through links on our articles, Future and its syndication partners may earn a commission. Four of the solar system's terrestrial planets, including Earth and a long-lost world, likely started life waltzing around the sun to a fixed rhythm, according to a new study. The findings also suggest that those planets formed earlier than previously thought. Astronomers have been increasingly interested in how planetary systems change their internal architecture on cosmic timescales, motivated by several recent exoplanet family discoveries, like the seven-planet cohort orbiting the tiny star TRAPPIST-1. Past research has found that one early stage in a planetary family's metamorphosis involves pairs, triplets or entire systems moving in a rhythmic beat — called resonance — around their parent star. Planets in resonance have orbital periods that form a whole-number ratio. In the TRAPPIST-1 system, for instance, the innermost planet, TRAPPIST-1 b, completes eight orbits for five of its nearest neighbor's. Resonance arises among planets born within a protoplanetary disk — the disk of debris surrounding an infant star — that still contains gas. Such planets plow through the gas, exchanging their rotational motion with it, which often causes them to move toward the star. Many of these planets may come close enough to each other for their orbital periods to "resonate," or become whole-number multiples. Today, the solar system's planets aren't in resonance (although Venus and Mars come close, with an orbital-period ratio of 3.05:1). But in 2005, astronomers showed that Jupiter and Saturn waltzed in a resonant beat soon after their birth. This dance halted abruptly 4.4 billion years ago, however, when the protoplanetary gas disk started evaporating, pushing Saturn, Uranus and Neptune outward in an event called the giant planetary instability. Related: What's the maximum number of planets that could orbit the sun? Until now, though, nobody had examined whether the terrestrial planets have ever been in resonance, Chris Ormel, an associate professor at Tsinghua University in China and co-author of the new study, told Live Science by email. This was because "an alternative theory — that the planets formed by a series of giant impacts — was thought to be adequate" to explain how they currently behave, he said. But research from 2013 analyzing Martian isotopes suggested that terrestrial planets could have formed when the protoplanetary disk was still rich in gas, about 10 million years after the solar system's birth. This meant the terrestrial planets may have once been in resonance. To examine the hypothesis, the new study's authors created computer models of the infant solar system. Each model included two giant planets — Jupiter and Saturn — along with four rocky worlds: Mars, Theia (a hypothetical Mars-size object whose collision with early Earth formed our moon), early Earth (prior to Theia's collision) and Venus. Mercury is widely believed to have been created by giant impacts, so the researchers excluded it from the simulations. In all of the models, the team placed Saturn closer to Jupiter than it is today and had the rocky worlds grow by accumulating either pebbles or larger, trillion-ton rock blocks. In most simulations, Venus, Earth, Theia and Mars formed a 2:3:4:6 resonant chain within a million years of simulated time. The researchers then performed 13,200 simulations of the planets' potential movements over a 100-million-year interval, considering the gravitational tugs each planet exerted on the others. At the 10 million-year mark, however, the researchers made Saturn move outward "to simulate the giant planet instability," Shuo Huang, a doctoral student at Tsinghua University and the study's first author, told Live Science by email. The researchers found that, based on the selected parameters, up to half of the simulations re-created the terrestrial planets' current configuration. This included aspects like the occurrence of a single Theia-Earth collision and the 3.05:1 orbital-period ratio of Venus and Mars — a relic of their past resonance. Additionally, the findings suggest the planets formed in the gas-filled protoplanetary disk, within the first 10 million years of the solar system's creation, which is at least 20 million years older than current models predict.

Could that change its prospects for life? One planet that could confirm how old the rocky inner worlds are is Venus. Because it (unlike Earth and Mars) hasn't suffered any giant impacts, the authors think its mantle will reflect its ancient origin. And future missions could collect such mantle samples, Huang said. The findings also indicate that outer giant planets can destabilize their inner companions tremendously. The authors said this may explain why resonant systems like TRAPPIST-1 don't have giant outer planets. The new study was published July 18 in The Astrophysical Journal.

Netflix just added a gripping sci-fi thriller series with 100% on Rotten Tomatoes — and it's already cracked the top 10
When you buy through links on our articles, Future and its syndication partners may earn a commission. I've always loved movies and shows that incorporate time travel. As a dedicated thriller fan, I find the narrative hook ripe for shocking twists and highly memorable moments. And 'The Lazarus Project' is more proof that when used well, the narrative device creates practically unmissable TV. This British series originally aired on Sky Max in the summer of 2022 (and TNT in the U.S.), but now has found a new streaming home on Netflix. Subscribers hooked by the elevator pitch of a secret organization altering time to save the world will be pleased to know the streaming service hasn't just added a single season of the show either. Both seasons of "The Lazarus Project" have now landed on the big red streamer. At 16 episodes total, 'The Lazarus Project' is the perfect binge-watch this week. It's one of those rare shows that will have your finger hovering over the 'play next episode' button before the credits have even started rolling. With each new twist and turn, you'll be drawn further into its world of time loops, tricky moral questions and compelling characters. The show is already proving quite a hit on Netflix. Less than 48 hours after its arrival on the platform, and it's found its way into the Netflix top 10 most-watched shows list. It currently ranks No. 5 behind original series like "The Hunting Wives" and "Untamed," but as more subscribers get hooked by its many twists, it could even rise to No. 1. So, if you're on the hunt for your next Netflix binge, 'The Lazarus Project' makes a very compelling case for itself. Here's everything you need to know about this gripping sci-fi thriller series, and why critics were so impressed it managed to pull a rare 100% score on Rotten Tomatoes. What is 'The Lazarus Project' about? George (Paapa Essiedu) might be losing his grip on reality. Waking up on July 1, he lives out an eventful three months that include professional success; marrying his girlfriend, Sarah (Charly Clive); preparing for their first child; and facing a global pandemic. But then he awakens on the morning of July 1, with time having reset back to three months earlier. Stuck in a time loop, reliving the same events over and over again, nobody but George seems to be aware that time is resetting. But he's not going insane. Instead, he's one of a select group of people who can uniquely perceive the flow of time and remember the events of each timeline reset. Invited to join the Lazarus Project, he becomes part of an underground organization that works from the shadows to save the world from universe-ending threats, but the ability to rewrite the past and change the future comes with serious temptations. And George is soon forced to choose between the Lazarus Project's strict rules and saving a loved one. 'The Lazarus Project' reviews — here's why critics rate it 100% On review site Rotten Tomatoes, 'The Lazarus Project' season 1 holds a rare perfect 100% rating. This score comes from a relatively low sample size of 14 reviews, but it still speaks to the sci-fi thriller's quality and the way it managed to grip viewers across its run. 'It's all as fun to watch as it is compelling to consider,' said Judy Berman of TIME Magazine. While Cristina Escobar of praised the series for its 'thoughtful exploration of moral questions' and for packing 'plenty of suspense.' Metro's Sophie Laughton felt the show was 'a watch that's worth the ride,' and Brad Newsome of the Sydney Morning Herald said, 'This intelligent, imaginative sci-fi thriller series sets itself apart with complex, believable characters and dashes of incidental low-key humor.' "Affirming [creator] Joe Barton's status as one of the best screenwriters in the game, The Lazarus Project is exactly the kind of head-spinning, heart-pounding TV that you'll be left wanting to revisit time and again," said Jordan King of Empire Magazine in a four-star review. Dan Einav of the Financial Times was a little more mixed than some critics. 'The opening episode can feel off-puttingly clunky and déjà vu-inducing,' explained Einav. However, he noted that 'In subsequent episodes, thankfully, the eight-parter becomes more intriguing.' The show's second season, which originally debuted in November 2023, doesn't have enough reviews on Rotten Tomatoes for a rating, but the critical takes listed are universally positive. 'This twisty time-loop thriller gets even more dramatic in its second outing. Paapa Essiedu's George is a jittery joy in a smart, sharply scripted show that's lots of fun to watch,' said Leila Latif of the Guardian about 'The Lazarus Project's' second season. Should you stream 'The Lazarus Project' on Netflix? If you're looking for a compelling sci-fi series with intriguing twists and plenty of time-travel shenanigans, then 'The Lazarus Project' isn't just worthy of your watchlist — it should be right at the very top of your streaming pile. It's a compelling thriller that'll hook you instantly. Paapa Essiedu's performance is one of my favorite parts of the show, creating a character in George who is plenty likable, and with some conflicting emotions at play. Yes, he wants to save the world from global catastrophe, but he's got understandable personal desires as well, and these two goals conflict in a way that leads to seriously high-stakes drama. While much of 'The Lazarus Project' is dedicated to intense drama and universe-ending threats, there's just the right amount of humor in the mix. Like when Lazarus Project member Archie (Anjli Mohindra) explains George's abilities to him by describing him as a 'mutant,' but making a point of noting he's "not like Wolverine.' Of course, as a show about time loops and changing the past to alter the future, there is a degree of time travel jargon in 'The Lazarus Project,' and the timeline can get a bit knotty as the show progresses. But these are minor quibbles, and for the most part, 'The Lazarus Project' does a good job of keeping things flowing without the plot spinning out of control. However, before you commit to watching based on all the praise written above, there is one frustrating element I need to warn you about. Sadly, 'The Lazarus Project' was canceled after two seasons, and the season 2 finale ended on a massive cliffhanger — one that looks set to go forever unresolved. So be prepared to be left with lingering questions. This blemish aside, 'The Lazarus Project' is a must-watch series for sci-fi thriller fans, and I'm hoping it's enjoyed a deserved resurgence now that it's arrived on Netflix. In fact, maybe if it manages to make such a large splash on the world's biggest streaming service, then it could be revived for a third season. Or maybe that's just wishful thinking on my part. 'The Lazarus Project' is among the final few major additions to Netflix this month, but the streaming service has already confirmed its slate of new content for August.
