Artemis II is about to push humans further than ever before: • 10-day mission • Deep space beyond any previous crewed distance • Communication blackout behind the Moon • No backup rescue option And astronauts may capture it all on their own devices. #Artemis #SpaceTravel #SpaceNews

@latestincosmos Fun fact: Bananas make antimatter! One positron every 75 minutes per banana 🍌. Need 1 gram? Cool, just wait ~10,000,000x the universe's age. Or until the heat death of everything

🚨: Forget gold or diamonds — the true king of value is antimatter, the rarest and most powerful material ever created by humans. Estimated at $62.5 trillion per gram, it’s not mined but manufactured atom by atom inside massive particle accelerators like CERN’s Large Hadron Collider. Antimatter is the mirror opposite of regular matter. When the two meet, they annihilate each other completely — releasing 100% of their mass as energy, according to Einstein’s famous equation, E = mc². That’s far beyond the efficiency of nuclear power, making antimatter the ultimate energy source — at least in theory. Right now, scientists can produce only a few nanograms per year, and storing it is nearly impossible. A single mistake or contact with normal matter causes instant disappearance. Still, researchers at NASA and CERN believe antimatter could one day power deep-space missions or even revolutionize medical imaging. It’s a glimpse into a future where energy itself becomes priceless — and humanity learns to hold the universe’s most explosive secret in its hands. Reference : CERN & NASA. (2024).

@LeyvaCFM_ Fun fact about the air we’re breathing. It is basically 78% nitrogen + 21% oxygen, with a sprinkle of 0.93% argon and ~0.043% CO₂ (~432 ppm). Tiny traces of everything else... plus whatever water vapor is floating around today! 🌍💨 #AtmosphereFacts

Y si el oxígeno en realidad es veneno que tarda entre 75 y 100 años en matarnos?

Fun fact: Venus does have sulfuric acid rain in its clouds, but it never reaches the ground. The rain evaporates while it’s still high in the atmosphere because Venus is so insanely hot near the surface. So Venus basically has “phantom acid rain” falling from the sky that disappears before it lands.

💫音も記録された、金星という“地獄の世界”ベネラ14号が見た最後の光景 1982年3月5日、ソ連の探査機ベネラ14号は、濃密な二酸化炭素大気と硫酸の雲を突き抜け、約90気圧・約465℃という極限環境へと降下しました。 これは地球の深海約1km相当の圧力に加え、鉛さえ溶ける高温という“灼熱の地獄”。この映像の特徴的な黄橙色の空は加工ではなく、厚い大気が青い波長を散乱させた結果であり、実際に金星に立てばこのような世界が広がっています。 地表は砂ではなく、割れた玄武岩が重なり合う硬質な火山地形。画面下には探査機の一部や機器が写り込み、過酷な環境の中で稼働している様子が生々しく伝わります。特に注目されるのが地質調査用アームで、地面の硬さや性質を調べるためにドリルを用いたサンプリングが行われました。その際の「ガリガリ」とした掘削音は、金星の地表に直接触れた数少ない“実際の音”として記録されています。 さらにこのミッションには有名な逸話があります。本来、地面を測定するはずだった装置の直下に、投棄されたレンズキャップが偶然落下。結果としてベネラ14号は“金星の地面ではなく自分の部品”を測定してしまいました。加えて、極限の高温によりカメラ周辺では「パチッ」という異音、すなわちレンズや機器の熱膨張・破損に伴う破裂音のような現象も記録されています。これは電子機器が限界に達していく過程そのものです。 設計寿命32分に対し、ベネラ14号は約57分間も稼働。この短い時間の中で、パノラマ画像、音声、大気データを取得しました。現在に至るまで、金星表面のカラー映像と音を直接伝える記録は、このベネラ計画の成果のみです。それは人類の技術の到達点であると同時に、宇宙の過酷さを物語る証でもあります。 1982年3月5日（着陸日） 探査機：ベネラ14号（ソ連） 撮影場所：金星・フェーベレグレード平原付近 クレジット：Soviet Academy of Sciences / NPO Lavochkin カスタマイズ：Picar

@CryptoWhale Follow for daily science based on facts not clickbait

@CryptoWhale How big do you thing these satellites are? They would have to be the size of a small country to see them from that far up in space

🌍 | Another photo of Earth released by NASA. And once again: no traces of airplanes, ships, or even satellites. Even though around 10,000-11,000 active satellitesare orbiting our planet, and more than 30,000 orbital objects are being tracked. And still, in these images- nothing.

Fun fact: Pluto is so cold that water ice becomes bedrock, while nitrogen ice can flow like glaciers across the surface.

@InterstellarUAP Small correction: it’s a ring-shaped collider that studies collisions at tiny scales, not a machine that “creates” energy from nothing. Its biggest payoff so far was helping confirm the Higgs boson in 2012, filling in a key gap in the Stand

🚨 The TRUTH about CERN Large Hadron Particle Collider in Switzerland They’re smashing particles underground at nearly the speed of light… turning energy into mass and unlocking the fabric of the universe Cleo Abram had exclusive access to the inside of CERN “When these protons collide at incredibly fast speeds releasing a ton of energy, that energy can turn into physical mass… which is crazy!” They found the “God Particle” - The Higgs boson. That explains why everything you and I feel exists. “We discover the building blocks now so that our children can build with them later in ways that we can’t possibly imagine.” What’s REALLY happening at CERN just blew my mind. What’s the one thing about the universe you want answered next? Should we build an even bigger collider? Drop your thoughts 👇
