Astronomers Discover an Ultra-Low Density ‘Marshmallow’ Planet ☁️ TOI-3757b is a gas giant about the same size as Jupiter but far less massive—making it incredibly light and puffy, almost like a marshmallow. This unusual planet orbits a red dwarf star located 580 light-years away in the constellation Auriga, completing an orbit every 3.4 days. Despite the star’s frequent intense flares, which usually strip planets of their atmospheres, TOI-3757b has retained a massive, low-density gaseous envelope. Scientists think its fluffiness could result from a slowly forming rocky core combined with an eccentric, oval-shaped orbit that causes its atmosphere to expand when it gets closer to its star. This discovery is significant because red dwarfs are the most common stars in the Milky Way. Finding such a large, puffy planet around one challenges earlier ideas about planet formation and survival in these systems. With an average density of only 0.27 grams per cubic centimeter, TOI-3757b may be the lightest gas giant ever observed.

HD 140283 or also known as the Methuselah Star, once seemed older than the universe itself. Turns out, it’s just about 12 billion years old, give or take a few hundred million. 🤍🪐🔭 #thespacechick #methuselahstar #spacefacts #stellar #astronomylovers #stars #spaceeducation #starfacts #hd140283 #spacecuriosity

HAT-P-26b is a warm Neptune-like exoplanet located roughly 437 light-years away in the constellation Virgo. It orbits its star in just 4.23 Earth days and features a puffy, low-density atmosphere composed mainly of hydrogen, helium, and detectable water vapor. Its low metallicity suggests a formation history that might have involved migrating from a colder, more distant region of its solar system. Additionally, the planet likely experiences extreme winds that could reach speeds of several thousand kilometers per hour, contributing to its dynamic and turbulent environment. #universe #space #ai #aiart #aiartcommunity #planet #planets #solarsystem #fyp #astronomy #austronaut #life #fyp

apchem edit before gta6? does this count as studying?? this was gonna be longer but then i realized i actually DO have to study so. i hope this flops this is so dumb 😭 #moles #stoichiometry #chemistry #chemistryedit #apchem

⁨ ⁨ این بحث که "اشکت دم مشکت بود" رو بذارید کنار. علم بیوشیمی ثابت کرده که گریه کردن در اوج فشار عصبی، نه یک واکنش احساسی ساده، بلکه یک مکانیسم پیچیده بقاست. 🧬 بیاید این پدیده رو ببریم زیر آنالیز دقیق آزمایشگاهی: 🔬 آنالیز بیوشیمیایی: اگر ساختار مولکولی اشک ناشی از پیاز (رفلکی) رو با اشک ناشی از غم و فشار (روانی) در محیط آزمایشگاه مقایسه کنید، با دو ترکیب شیمیایی کاملا مجزا روبرو میشید. 💉 تزریق مسکن طبیعی: اشک‌های احساسی حاوی غلظت بالایی از «لوسین انکفالین» (Leucine Enkephalin) هستند. این ماده در واقع یک نوع مسکن طبیعیه که عملکردی دقیقاً مشابه مورفین داره! مغز برای اینکه زیر فشار روانی منفجر نشه، دستور ترشح این ماده رو صادر می‌کنه. 🧠 سم‌زدایی از مغز: تحقیقات نشون داده این اشک‌ها حاوی هورمون‌های استرس مثل ACTH هستند. گریه کردن یعنی بدن داره به صورت فیزیکی سموم استرس رو از جریان خون خارج می‌کنه تا سیستم عصبی ریست بشه. 📉 💊 حس سبکی: اون حس آرامش بعد از گریه توهم نیست؛ اثر جذب شدن این مسکن‌های طبیعیه. حرف آخر: وقتی وسط بحث اشکش در میاد، اون ضعیف نیست؛ سیستم بدنش هوشمندتر از اونیه که اجازه بده سکته کنه. به بیولوژی احترام بذارید و برچسب "فیلم بازی کردن" نزنید. ⛔️ 💬 این پست رو بفرست برای کسی که فکر می‌کنه گریه نشونه ضعفه تا با حقیقت علمی روبرو بشه. ✈️ منابع: Frey, W.

Haven't heard this song in a while 🥲 - Follow @jankydankymemez for more! 🔥 Here’s another fascinating fact: Honey never spoils. Archaeologists have discovered pots of honey in ancient Egyptian tombs that are over 3,000 years old and still perfectly edible. The reason honey has such a long shelf life lies in its unique chemical composition. Honey is primarily made up of sugars, which are hygroscopic, meaning they attract moisture. When bees make honey, they process nectar by evaporating much of its water content, resulting in a thick, concentrated syrup. This low moisture content, combined with the high acidity of honey, creates an environment that is inhospitable for bacteria and microorganisms. Additionally, bees add an enzyme called glucose oxidase to the nectar, which breaks down into hydrogen peroxide when honey is stored. This further contributes to honey's antibacterial properties. Because of these factors, honey can last indefinitely when stored properly in a sealed container, away from moisture and light. This remarkable ability to resist spoilage is one of the reasons honey has been used as a food source and preservative for thousands of years. It's not just a sweet treat; it's a testament to the incredible processes of nature! #reels #memes #wholesome #dancing #fyp

Soap was heavily diluted to demonstrate the coatings beading properties. A ceramic-coated car is hydrophobic due to the molecular structure of the ceramic coating, which forms a strong bond with the paint and creates a smooth, non-porous surface. This surface repels water, causing it to bead up and roll off rather than soaking into the paint. The coating’s chemical composition reduces surface tension, making it harder for water, dirt, and contaminants to adhere. As a result, water slides off easily, which helps keeps the car cleaner, and makes washing easier.

My new hyperfixation is UV glass and the chemical composition of other glassware. ☺️💜❤️💜 My Dad had to go to the hospital for heart problems. It was scary and I do not feel like talking about it. He's out now, but he has to see a cardiologist. 😕 Monotropism is the tendency to focus on a small number of interests at a time, and to neglect or not notice others. It shows up frequently in #autism, and can be found in #ADHD folks as well. People with monotropism may find it difficult to shift their attention from one thing to another. When a special interest becomes all consuming, it can produce great things, but it can also become a problem. It can also exacerbate #ARFID, (avoidant restrictive food intake disorer) making it more difficult to remember to eat. Do you experience monotropism?❤️💜❤️

In a world that glorifies data, analysis, and spreadsheets, we've been trained to mistrust the quiet, gut-level voice inside us. We call it "unscientific" or "emotional." But what if that instinct is not the opposite of intellect, but a more ancient, sophisticated form of intelligence? Your instinct is the accumulated wisdom of every one of your ancestors, encoded in your DNA. It’s the supercomputer that runs in the background, processing millions of data points (micro-expressions, environmental cues, subtle patterns) that your conscious mind is too slow to register. Intellect is the map. Instinct is the compass. Your intellect gathers all the available information and draws a careful, logical map. It shows the roads, the distances, the potential obstacles. It's incredibly valuable. But your instinct is the compass. When the map is incomplete, when a road is washed out, or when a hidden, more beautiful path isn't on the map at all, the compass points true north. It knows the direction you must go, even when you can't see the path. When to Let Instinct Take the Lead: Your Gut is Smarter Than You Think 1. In High-Stakes, Time-Sensitive Decisions. · A firefighter doesn't have time to analyze the chemical composition of smoke. He feels a "wrongness" and orders his team out seconds before the floor collapses. His instinct, born of experience and primal awareness, processed the heat, the sound, the smell faster than his logic could. · Motivation: Your body often knows danger—and opportunity—before your brain has finished its PowerPoint presentation. Trust that feeling. 2. When Choosing Your Path (Career, Relationships, Life). · Your intellect can list the pros and cons of a job: the salary, the benefits, the prestige. But your instinct knows if the environment will drain your soul. It knows if a person is trustworthy, not by their resume, but by the feeling you get when you're with them. · Motivation: Don't just make a "smart" choice. Make a right choice. The one that feels aligned, that gives you energy, that whispers "yes" even when the logic is scary. A life built only on intellect can be successful but empty. #fun
