Ploonets hell yeah Runaway moons get a charmingly goofy name

first_img 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.

Hey Circuit City Where are all the Bargains

first_imgFebruary 6, 2009 We checked out a closeout sale in Norwalk, Connecticut earlier this week and found once we got past the signs screaming “30 percent off” there weren’t a whole lot of bargains to be had. We did find some good deals, but far fewer than we had hoped.As you’ve no doubt heard, Circuit City, the nation’s second largest retailer, has gone belly up.We were hoping to find loads of great deals. While some of Circuit City’s stock such as cables and wiring and DVD movies at the store we visited were marked down 30 to 20 percent, big tag items were only cut by 10 percent. Still, in this economic climate even a 10 percent off sale is welcome.To find out just how good the deals were at Circuit City we compared prices with four other big retailers – Best Buy, Amazon.com, Fry’s Electronics, and J&R Electronics.Circuit City Sale Reality CheckThe verdict? Our inner-bargain hunter was crushed when many sale items sold at Circuit City were no bargain at all. We found cameras, HDTVs, printers and GPS systems priced 10 to 20 percent higher than the other major retailers. Let’s take a look.Circuit City has Canon’s HV30 Camcorder going for $809.99, while we found the same model on sale at BestBuy.com for $791.99. A Canon Powershot G10 was being liquidated for $449.99, but it was almost 10 percent less on Amazon.com.Cameras not your thing? Okay, how about a nice Sony 1080p 52″ LCD TV? You can get it at Circuit City for $1979.99, but Best Buy can beat that by 30 bucks and Amazon blows them both out of the water by 20 percent at $1599.GPS systems weren’t doing much better with a Garmin Nüvi 850 portable GPS going for $629.99, but Amazon’s got it beat by almost half with $399.99.So, Were There Any Deals?Yes. Some printers and iPods were worth braving the crowds for. You could get a Samsung clp 315 color laser printer for $179.10, beating out Best Buy, Amazon, Fry’s and J&R who could only manage $189 between them.But the best deals to be had were the iPods. An 8 GB iPod Touch was going for $206.99 at Circuit City, while Amazon had it at $214.95. The 32GB iPod Touch was a steal at $359.99, beating out both Fry’s and J&R who could only get down around $369.Shop Smart, Consider Returns, Service, Etc.So if you’re looking for smaller items, Circuit City might be the place for you. However, going out of business sales and liquidations are notorious for being promotions to draw people into a store-remember CompUSA? This seemed to be the case with the Circuit City store we visited.If you do buy some digital gear at Circuit City this weekend check the price before you buy and make sure whatever it is you pick up works before you take it to the register. Sales staff reminded us that all sales were final and any problems with products purchased at the store would have to be addressed by the product manufacturer.Not a big deal if you’re buying an iPod, but if you’ve got your eyes on an HDTV you might want to be extra careful-postage for those things can really dent your wallet!(Additional reporting by Tom Spring) How Success Happens Hear from Polar Explorers, ultra marathoners, authors, artists and a range of other unique personalities to better understand the traits that make excellence possible.
