Exiled Iranian filmmaker Mohammad Rasoulof's definition of home is shiftingNEW YORK (AP) — Shortly before he was to be flogged and imprisoned for eight years, Mohammad Rasoulof fled Iran. His weekslong journey would take him from Tehran, through rural Iranian villages, on foot across a mountainous borderland and ultimately to Hamburg, Germany. As arduous and dangerous as the trip was, Rasoulof’s travels had an added wrinkle: He was trying to finish a movie at the same time. A week after arriving in Germany, Rasoulof would premiere his film, “The Seed of the Sacred Fig” at the Cannes Film Festival in France. As he fled, Rasoulof was preoccupied with the movie’s edit, which was being carried out in Germany. “I remember when I was sitting in the car that was driving me to the border,” Rasoulof says. “I had my laptop and I was taking notes and sending them to my editor. The two friends who were taking me kept saying, ‘Put that thing away for a second.’” In Cannes, “The Seed of the Sacred Fig” won a special jury prize and Rasoulof was celebrated with a 13-minute standing ovation. The movie has since been hailed as one of the best of the year, and arguably its most daring. Rasoulof made “Sacred Fig” clandestinely in Iran, directing scenes from a separate location to avoid raising suspicions. (The opening titles read: “When there is no way, a way must be made.”) Its story — a devastating family drama set during the 2022 protests that engulfed Iran — would surely only add to Rasoulof’s prison sentence. So after all of this, how is he feeling? When he recently met with The Associated Press for an interview, Rasoulof shrugged. “Ordinary,” he says. Rasoulof, 52, has a more gentle, bemused presence than some of his films would suggest. But how could Rasoulof, after what he’s lived through this year, feel anything like ordinary? “I still haven’t grasped the meaning of exile,” he explains. “I think it will take some time. The feeling of that void has not hit me yet, and I think it may never come.” Rasoulof has been busy traveling from film festival to film festival. In September, he and his 24-year-old daughter attended the Telluride festival in Colorado. Many more such stops were to come. Since fleeing Iran, Rasoulof has effectively been immersed in the world he’s long known: cinema. “Maybe I am living in the world of cinema, and maybe that’s why things are so familiar,” he agrees. “Maybe that’s why I don’t feel I’m in exile.” “The Seed of the Sacred Fig,” currently playing in theaters, is the Oscar submission from Rasoulof’s adoptive home, Germany. He’s settled in with his family, grateful for how the country has welcomed him. Speaking through an interpreter, Rasoulof grants that he’ll probably always mentally have a bag packed, ready to return to Iran should the chance ever come. But what “home” constitutes has changed for him. “I might be able to change this concept of home for myself,” he says. “I walk on the streets here and I see people of different colors and forms from all over the place, and they all call this place home. So there’s always the chance that one can build something new.” How oppressive politics can infiltrate the home is central to “The Seed of the Sacred Fig.” It concerns a family of four: Iman (Missagh Zareh), a lawyer newly appointed to the Revolutionary Court in Tehran; his wife, Najmeh (Soheila Golestani) and their two daughters, Rezvan (Mahsa Rostami) and Sana (Setareh Maleki). Iman is proud of his high position, but, when the government crackdown on protesters following the death of Mahsa Amini accelerates, his daughters are increasingly at odds with him. After Iman's gun goes missing, his wife and daughters turn into suspects. “The Seed of the Sacred Fig,” populated with real cellphone videos from the protests, plays out as an excruciating microcosm of Iranian society. “It wasn’t like I put those videos in. They just came in,” says Rasoulof. “The reality is that it was through those videos I realized what happened. When the Woman, Life, Freedom movement occurred, I was in prison.” Rasoulof has spent several spells in Tehran’s Evin Prison. In 2010, he was arrested on set for filming without a permit. In 2022, he was jailed for seven months after pursuing the release of another of Iran’s most prominent filmmakers, Jafar Panahi. Panahi, who secretly made the film “No Bears,” was only released in 2023 after commencing a hunger strike. “My windows at home opened to the hills that have the Evin prison in them,” says Rasoulof. “I knew behind those walls many of my friends were sitting.” Rasoulof, inspired by the courage of the younger generation, resolved to pour the same spirit into “The Seed of the Sacred Fig.” Although it wasn’t until Rasoulof’s appeal of his sentence failed that he resolved to flee, he grants that deciding to make “Sacred Fig” essentially sealed his fate. “Making this film was part of that decision,” he says. “Although I had made up my mind earlier, because it was such a bitter decision, I was denying it and delaying it, waiting for a miracle to allow me to stay.” “I would open the fridge to make sure there was nothing there that would go bad,” he adds. “It was a strange circumstance.” For the film's actors and crew members, signing up for the movie meant also becoming co-conspirators. Everyone knew the risks. And, like Rasoulof, many of them have since left Iran. Rostami and Maleki also now live in Germany. Asked if his collaborators are all currently safe, Rasoulof responds: “No one is safe from the Islamic Republic.” In his new life, Rasoulof is experiencing freedoms he never had in Iran. His films, for example, are widely available outside his native country but not in Iran. His prize-winning 2020 drama “There Is No Evil,” about capital punishment in Iran, is banned — though, ironically, Rasoulof’s prison guards enjoyed watching it with him from a flash drive. “I haven’t seen many of my films on a big screen, especially my last film,” he says. “I really want to see ‘There Is No Evil’ on a big screen. A festival in Portugal has promised to take me to see my own film.” The name of Rasoulof’s film comes from his memory of an ancient fig tree he once visited on an island in the south of Iran. It’s a tree that, with apparent metaphorical meaning for the Iranian government, spreads its seeds onto other trees, killing them and growing in their place. Rasoulof pulls out his phone to share a photo of his apartment in Tehran. Outside a large window, you can see the walls of Evin running along a craggy hillside. Inside are many houseplants. “This is my home,” he says. “I have a lot of plants. I really miss my plants. I have a neighbor who takes care of them for me. I actually have a fig tree at home.” Jake Coyle, The Associated Press

Best glimpse ever into icy planetesimals of the early solar system December 19, 2024 University of Central Florida New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the distribution of ices in the early solar system and how TNOs evolve when they travel inward into the region of the giant planets between Jupiter and Saturn, becoming centaurs. TNOs are small bodies, or 'planetesimals,' orbiting the sun beyond Pluto. They never accreted into planets, and serve as pristine time capsules, preserving crucial evidence of the molecular processes and planetary migrations that shaped the solar system billions of years ago. These solar system objects are like icy asteroids and have orbits comparable to or larger than Neptune's orbit. Prior to the new UCF-led study, TNOs were known to be a diverse population based on their orbital properties and surface colors, but the molecular composition of these objects remained poorly understood. For decades, this lack of detailed knowledge hindered interpretation of their color and dynamical diversity. Now, the new results unlock the long-standing question of the interpretation of color diversity by providing compositional information.

For decades, this lack of detailed knowledge hindered interpretation of their color and dynamical diversity. Now, the new results unlock the long-standing question of the interpretation of color diversity by providing compositional information. "With this new research, a more-complete picture of the diversity is presented and the pieces of the puzzle are starting to come together," says Noemí Pinilla-Alonso, the study's lead author. "For the very first time, we have identified the specific molecules responsible for the remarkable diversity of spectra, colors and albedo observed in trans-Neptunian objects," Pinilla-Alonso says. "These molecules -- like water ice, carbon dioxide, methanol and complex organics -- give us a direct connection between the spectral features of TNOs and their chemical compositions." Using the James Webb Space Telescope (JWST), the researchers found that TNOs can be categorized into three distinct compositional groups, shaped by ice retention lines that existed in the era when the solar system formed billions of years ago. These lines are identified as regions where temperatures were cold enough for specific ices to form and survive within the protoplanetary disk. These regions, defined by their distance from the sun, mark key points in the early solar system's temperature gradient and offer a direct link between the formation conditions of planetesimals and their present-day compositions. Rosario Brunetto, the paper's second author and a Centre National de la Recherche Scientifique researcher at the Institute d'Astrophysique Spatiale (Université Paris-Saclay), says the results are the first clear connection between formation of planetesimals in the protoplanetary disk and their later evolution. The work sheds light on how today's observed spectral and dynamical distributions emerged in a planetary system that's shaped by complex dynamical evolution, he says. "The compositional groups of TNOs are not evenly distributed among objects with similar orbits," Brunetto says. "For instance, cold classicals, which formed in the outermost regions of the protoplanetary disk, belong exclusively to a class dominated by methanol and complex organics. In contrast, TNOs on orbits linked to the Oort cloud, which originated closer to the giant planets, are all part of the spectral group characterized by water ice and silicates." Brittany Harvison, a UCF physics doctoral student who worked on the project while studying under Pinilla-Alonso, says the three groups defined by their surface compositions exhibit qualities hinting at the protoplanetary disk's compositional structure. "This supports our understanding of the available material that helped form outer solar system bodies such as the gas giants and their moons or Pluto and the other inhabitants of the trans-Neptunian region," she says. In a complementary study of centaurs published in the same volume of Nature Astronomy , the researchers found unique spectral signatures, different from TNOs, that reveal the presence of dusty regolith mantles on their surfaces. This finding about centaurs, which are TNOs that have shifted their orbits into the region of the giant planets after a close gravitational encounter with Neptune, helps illuminate how TNOs become centaurs as they warm up when getting closer to the sun and sometimes develop comet-like tails. Their work revealed that all observed centaur surfaces showed special characteristics when compared with the surfaces of TNOs, suggesting modifications occurred as a consequence of their journey into the inner solar system. Among the three classes of TNO surface types, two -- Bowl and Cliff -- were observed in the centaur population, both of which are poor in volatile ices, Pinilla-Alonso says. However, in centaurs, these surfaces show a distinguishing feature: they are covered by a layer of dusty regolith intermixed with the ice, she says. "Intriguingly, we identify a new surface class, nonexistent among TNOs, resembling ice poor surfaces in the inner solar system, cometary nuclei and active asteroids," she says. Javier Licandro, senior researcher at the Instituto de Astrofisica de Canarias (IAC, Tenerife, Spain) and lead author of the centaur's work says the spectral diversity observed in centaurs is broader than expected, suggesting that existing models of their thermal and chemical evolution may need refinement. For instance, the variety of organic signatures and the degree of irradiation effects observed were not fully anticipated, Licandro says. "The diversity detected in the centaurs populations in terms of water, dust, and complex organics suggests varied origins in the TNO population and different evolutionary stages, highlighting that centaurs are not a homogenous group but rather dynamic and transitional objects" Licandro says. "The effects of thermal evolution observed in the surface composition of centaurs are key to establishing the relationship between TNOs and other small bodies populations, such as the irregular satellites of the giant planets and their Trojan asteroids." Study co-author Charles Schambeau, a planetary scientist with UCF's Florida Space Institute (FSI) who specializes in studying centaurs and comets, emphasized the importance of the observations and that some centaurs can be classified into the same categories as the DiSCo-observed TNOs. "This is pretty profound because when a TNO transitions into a centaur, it experiences a warmer environment where surface ices and materials are changed," Schambeau says. "Apparently, though, in some cases the surface changes are minimal, allowing individual centaurs to be linked to their parent TNO population. The TNO versus centaur spectral types are different, but similar enough to be linked." How the Research Was Performed The studies are part of the Discovering the Surface Composition of the trans-Neptunian Objects, (DiSCo) project, led by Pinilla-Alonso, to uncover the molecular composition of TNOs. Pinilla-Alonso is now a distinguished professor with the Institute of Space Science and Technology in Asturias at the Universidad de Oviedo and performed the work as a planetary scientist with FSI. For the studies, the researchers used the JWST, launched almost three years ago, that provided unprecedented views of the molecular diversity of the surfaces of the TNOs and centaurs through near-infrared observations, overcoming the limitations of terrestrial observations and other available instruments. For the TNOs study, the researchers measured the spectra of 54 TNOs using the JWST, capturing detailed light patterns of these objects. By analyzing these high-sensitivity spectra, the researchers could identify specific molecules on their surface. Using clustering techniques, the TNOs were categorized into three distinct groups based on their surface compositions. The groups were nicknamed "Bowl," "Double-dip" and "Cliff" due to the shapes of their light absorption patterns. They found that: For the centaurs study, the researchers observed and analyzed the reflectance spectra of five centaurs (52872 Okyrhoe, 3253226 Thereus, 136204, 250112 and 310071). This allowed them to identify the surface compositions of the centaurs, revealing considerable diversity among the observed sample. They found that Thereus and 2003 WL7 belong to the Bowl-type, while 2002 KY14 belongs to the Cliff-type. The remaining two centaurs, Okyrhoe and 2010 KR59, did not fit into any existing spectral classes and were categorized as "Shallow-type" due to their unique spectra. This newly defined group is characterized by a high concentration of primitive, comet-like dust and little to no volatile ices. Previous Research and Next Steps Pinilla-Alonso says that previous DiSCo research revealed the presence of carbon oxides widespread on the surfaces of TNOs, which was a significant discovery. "Now, we build on that finding by offering a more comprehensive understanding of TNO surfaces" she says. "One of the big realizations is that water ice, previously thought to be the most abundant surface ice, is not as prevalent as we once assumed. Instead, carbon dioxide (CO 2 ) -- a gas at Earth's temperature -- and other carbon oxides, such as the super volatile carbon monoxide (CO), are found in a larger number of bodies." The new study's findings are only the beginning, Harvison says. "Now that we have general information about the identified compositional groups, we have much more to explore and discover," she says. "As a community, we can start exploring the specifics of what produced the groups as we see them today." The research was supported by NASA through a grant from the Space Telescope Science Institute.
