Hunt for first ‘exomoon’ zeroes in on top prospect of surprising size Exomoons could have ‘moon-moons,’ and they might support alien life Hey peeps!😃I was inspired by the Ploonet news yesterday to go back to making infographics! So here is a summary of Ploonet formation!🌑Hope you enjoy 💖🙏Also just like the other ones it is free to use and modify!#ploonets #scicomm #sciart #astronomyfact #sciencetwitter pic.twitter.com/ZLxXwURDXX— Dr. Héloïse Stevance 💖💥 (@Sydonahi) July 10, 2019 Sci-Tech 27 Photos Cosmic dead ringers: 27 super strange-looking space objects Space The last paper submitted to the ArXiv by our team shows that regular exomoons orbiting close-in giant planets are tidally unstable, and prone to be unavoidably expelled from the planet’s orbit to circumstellar locations. https://t.co/1uLL2qctre (Follow the thread) pic.twitter.com/g1hVqgYtGo— Mario Sucerquia (@MarioSucerquia) July 1, 2019 Share your voice NASA released this illustration of what an exomoon might look. NASA/ESA/L. Hustak Dear Diary, I dream of one day running away from my home in orbit around my gas giant planet, which is now migrating ever closer to our solar system’s star. Thanks for the push, gravitational forces! Soon I will be free from my planetary orbit and I will no longer be just another moon. I will break away and become … a ploonet!If you’re getting “moonmoon” vibes from this whole ploonet thing, you’re not alone. The term combines the words “planet” and “moon” to describe a hypothetical moon that breaks away from its host and became its own kind of small planet.Ploonets are now a thing thanks to a paper submitted for review to the Monthly Notices of the Royal Astronomical Society journal. It’s called Ploonets: formation, evolution, and detectability of tidally detached exomoons.Astrophysicist Mario Sucerquia, the lead author, said he and co-author Jorge Zuluaga created the nickname “because we pretended to capture in a single word the entire biography of these objects: planets with a moonish origin.” He said he finds the term “captivating.” The scientists considered going with “moonets,” but wanted to reinforce how they end up as planets. As Stevance points out, ploonets are likely to live fast and die young. If you’d like to immerse yourself in all the juicy astrophysics details of ploonets, be sure to check out Sucerquia’s own Twitter thread on the matter. He discusses how we might able to spot ploonets, some of which could end up looking like giant comets or just regular exoplanets. Post a comment The researchers ran simulations of a large exomoon (a moon located around a planet in another solar system) orbiting a gas giant (think of a hot Jupiter) that’s moving ever closer to its star. The simulations didn’t end well for a lot of these hypothetical moons, which faced demises including crashing into their own planets or burning up in the star. But some survived in the simulations to achieve their own orbits around the star. Voila, ploonets!Astrophysicist Heloise Stevance, who was not involved in the paper, created and tweeted a helpful infographic to explain how this all works. 0 But here’s the kicker: “The Earth’s tidal strength is gradually pushing the Moon away from us at a rate of about three centimeters per year,” he tweeted. “Therefore, the moon is indeed a potential ploonet!” Fine then, I’ll see you on the dark side of the ploonet.

Cartoons taking aim at Rohingya Muslims are spreading rapidly across social media in mainly Buddhist Myanmar, where public opinion on the crisis stands in stark contrast to the outcry overseas.Fanned by Myanmar’s civilian and military leaders, an information war has taken hold and is being embraced with gusto by a legion of satirists, meme-makers and internet trolls.Local cartoonists, many of whom earned their revered status for skewering the former junta, have taken aim at the Rohingya.One widely-shared sketch called ‘crocodile tears’ shows a group of reptiles swimming away from a bank of mutilated animals towards an eager Western cameraman.“I had to flee my motherland,” a crying crocodile says into the microphone, a swipe at the testimonies of Rohingya refugees who have arrived in Bangladesh with accounts of atrocities by Myanmar’s army.“There is something untrue about what they (the Rohingya) are saying,” Win Naing, one of Myanmar’s most famous cartoonists, told AFP.The 58-year-old, whose pen name is Aw Pi Kyeh, said he just wanted to provoke thought in a highly charged situation.“We draw cartoons with a spirit that loves the country.”For decades the paranoid former junta sequestered its people from technology, global opinion and debate.But since the country creaked open a few years ago Myanmar’s public has dived head first into Facebook and Twitter.Now, anti-Rohingya diatribes are being ‘liked’, shared and retweeted—reinforcing long-held religious hatreds against the minority.Since late August, around 430,000 Rohingya Muslims have fled to Bangladesh, escaping an army crackdown in Rakhine state which the UN has called ‘ethnic cleansing’.The global condemnation has triggered a defensive instinct in Myanmar where the Rohingya are not citizens and are broadly reviled.Keyboard warriors -Armed with crass humour, internet fame and riding a wave of public opinion, cartoonists have delivered sharp counter-punches.When Malala Yousafzai condemned fellow Nobel laureate Aung San Suu Kyi for failing to speak up for the Rohingya, one cartoonist hit back with a rendering of the Pakistani activist with human excrement instead of brains—a grim reference to her surgery after being shot in the head by the Taliban.A sketch by cartoonist Okka Kyi Winn, liked nearly 10,000 times on his Facebook page, showed a UN insignia wrapped in a Middle-Eastern keffiyeh, suggesting the body is in cahoots with the Arab world.While the intention may be pure satire, such images are contributing to a siege mentality in Myanmar, where keyboard warriors are trading blows with vocal pro-Rohingya groups scattered across the Muslim world.The prevailing view among the Buddhist majority is that foreign media and international NGOs have embellished the plight of the Rohingya and unfairly bashed Myanmar’s leader Aung San Suu Kyi.‘The Lady’ has refused to weigh in on the squall of claims and counterclaims, saying only that there is a ‘huge iceberg of misinformation’.Many outside Myanmar are baffled by the seeming lack of empathy, and the often violent rhetoric from a Buddhist people.But toxic Islamophobia has been brewing in the country for years, fed in part by official rhetoric that the Muslim Rohingya are foreign invaders intent on taking a Buddhist land.As his troops blanket Rakhine, Myanmar’s commander-in-chief Min Aung Hlaing has continued with Facebook posts branding the Rohingya as ‘terrorist extremists’ of ‘Bengali’ origin—a state-stamped slur that condemns them to the status of illegal migrants. ‘Better angels’ -Newspapers, TV debates and social media have followed suit, jeering at the Rohingya as they flee, says Sein Win of the Myanmar Journalism Institute.Some of the loudest noises are coming from people who fought repression under the junta, he told AFP, in a remarkable reshaping of the young democracy’s political landscape.“I am disturbed by the actions of the media, civil society and even former political activists. You need to care about humans across the board, not just when it suits you,” he said.On Friday US Deputy Assistant Secretary of State Patrick Murphy condemned the hate speech on social media and urged the “better angels” of the Myanmar people to find empathy for the Rohingya.But cartoonists such as Maung Maung Fountain (pen name) argue their sketches “don’t insult any religion or any people”.In one, he draws a camel—a code for Rohingya Muslims—that has edged its way into a tent made from the Myanmar flag then bellows ‘Human Rights’ at the startled Burmese man he has just evicted.“I meant say that some people want more and more rights and opportunities.”
Nigeria’s Boko Haram extremists are strengthening ties with the Islamic State group, as shown by reports that Nigerian militants are fighting in Libya, recent arrests in Lebanon and India and the blocking of thousands of suspected extremists from leaving Nigeria.Boko Haram pledged allegiance to IS in March and in June was declared its West African province. More than 1,000 people have been killed in the insurgency since President Muhammad Buhari was elected in March and pledged to halt the 6-year-old Islamic uprising blamed for the deaths of some 20,000.

They said he planned to fly to Nigeria on a forged Palestinian passport with a Nigerian visa.
Kolkata: The screening of “The Accidental Prime Minister” was on Friday cancelled at a Kolkata theatre due to security reasons amid protest demonstrations by youth Congress activists, police said. The film, directed by Vijay Ratnakar Gutte, released on Friday. It is based on a book with the same title written by Sanjaya Baru, who was media advisor to Manmohan Singh when he was Prime Minister. Baru’s book was published on April 20, 2014. Also Read – 3 injured, flight, train services hit as rains lash BengalActor Anupam Kher portrays the role of Singh while Akshaye Khanna stars as Baru. According to the viewers at the Hind Cinema near central Kolkata’s Chandni Chowk area, the show was cancelled after screening for just 10 minutes on its opening day. “The afternoon screening of ‘The Accidental Prime Minister’ has been cancelled due to security reasons. There was an agitation by a certain group outside the hall,” a senior officer of Kolkata Police said told IANS.

State youth Congress leadership claimed the content and the title of the film is derogatory towards Singh and other senior leaders of Congress and demanded that the film be banned. “The tile of the film itself is derogatory. What did the filmmaker want to imply by calling Manmohan Singh an accidental prime minister? Close to 100 activists of youth Congress in Kolkata protested in front of the theatre. It is good the screening has been stopped,” Bengal Youth Congress President Shadab Khan told IANS. Asked whether forcing to cancel the screening of a film can be termed as violation of freedom of speech, the leader said sentiments of the party workers have been hurt by the film. “The agitation was held as the sentiments of our activists were hurt. However, we are not planning any other agitations here as of now,” he added.
