What Would Happen to Earth if the Moon Was Destroyed? Destroying the moon could lead to major changes across Earth. For a starter, the debris released by the explosion would reach Earth’s surface. The big chunks would crash on Earth, while the smaller fragments might end up forming a ring around Earth. With the moon gone, there will be no more eclipses. However, the night sky would look much brighter. The stars will no longer be obscured by the moon’s brightness, and more and more of them will be visible. Although the moon is gone, the length of the day would remain the same. The moon contributes to the length of the day by a small fraction. Without the moon, only a few seconds will be lost in some parts of the world. Because the moon plays a role in the tidal forces around the globe, Earth would experience a 25% drop in tides across the oceans, seas and beaches. The sun will now be in charge of most tides that occur on Earth. Without the moon, the worst scenario would be the dramatic changes in Earth’s axial tilt, which will become unstable. The moon has kept Earth’s axial tilt values between 22.1° and 24.5°. Because the moon would no longer be around, the unstable axial tilt would exceed 45°, leading to major changes in global temperatures. From time to time, the equator would become freezing cold while the poles would become extremely hot. Different parts of the world would experience ice ages every few thousand years.

Sky observations: LLT ( Local legal time) 19: 10. The sky is partially clouded. The clouds move from S- W. No wind at the Earth surface. Moon rised. m= 0; Phase 60%, A= +38°, H ( height above Horizon) = 26°; At LLT 20:00 There are no visible clouds in the vicinity of the Moon. The Moon is surounded by a double yellow halo. The first halo have a radius of ~ 1 °, while the second ~ 1,5°. I suppose, that the first halo is due to Lunar dust. The origin of the second halo is unknown, but We could hypothesise about very thin almost invisible and very high clouds ( ???). Polar star can be observed from the 5- th step at the entrance to the house. This means that the Polar Star move to East from its mean position. At LLT 20: 45, the smaller halo radius decreases to 0,8°. t=+13°C. At ~ LLT 2:20 Moon set. Note: When the Moon enters completely in a clouded region of the sky, obviously one observe colored haloes around. The colors vary from orange to violete, sometimes also could be red.

2024 December 20 The Long Night Moon Image Credit & Copyright: Giorgia Hofer and Dario Giannobile (Pictores caeli) On the night of December 15, the Full Moon was bright. Known to some as the Cold Moon or the Long Night Moon, it was the closest Full Moon to the northern winter solstice and the last Full Moon of 2024. This Full Moon was also at a major lunar standstill. A major lunar standstill is an extreme in the monthly north-south range of moonrise and moonset caused by the precession of the Moon's orbit over an 18.6 year cycle. As a result, the full lunar phase was near the Moon's northernmost moonrise (and moonset) along the horizon. December's Full Moon is rising in this stacked image, a composite of exposures recording the range of brightness visible to the eye on the northern winter night. Along with a colorful lunar corona and aircraft contrail this Long Night Moon shines in a cold sky above the rugged, snowy peaks of the Italian Dolomites. 🔗Discuss | ℹ️About APOD 🎞High Resolution

Did you know? Living on the moon means living lighter—but at a cost. With reduced gravity, bone loss and muscle weakening are inevitable without constant adaptation.

Will the one thing saving us from climate change eventually kill us all? ☠️ This Halloween, don’t be haunted by just ghosts and vampires... 👻 While solar energy is our best chance at survival, the sun isn’t just a friend. 🌕 In time, it might spell our doom - even while it keeps us alive! Here are some scary truths about the sun scientists don't want you to know... 🥵 Our Sun is stable for now, but it's slowly getting brighter—eventually enough to start evaporating our water supply, boiling the oceans dry and “bleeding” water from our atmosphere until Earth becomes unbearably hot and barren. 🪦 The Sun’s inevitable death: in the end, the Sun will expand into a red giant and swallow up Earth. When the Sun dies, so will our planet. 🔥 Solar flares and coronal mass ejections: these phenomenons can disrupt electronics, GPS, and power grids, potentially causing widespread outages. ⚡ Coronal holes allow solar wind to escape, leading to geomagnetic storms that can damage satellites and pose serious risks for astronauts in space. 🧲 Geomagnetic Storms: In 1859, a massive solar storm known as the Carrington Event hit Earth, causing intense geomagnetic disturbances - so strong that the Northern Lights were visible as far as Hawaii, and telegraph systems sparked and caught fire. If a similar event happened today, it could paralyze modern life for years. ⚰️ Lastly, perhaps the most likely risk in our lifetime: the silent, invisible danger of UV radiation, powerful enough to cause skin cancer, cataracts, and weaken immune systems. So although the sun is both our savior and our endgame, let's harness its power wisely while we can...

Off to the Moon. 👩🏾🏫 1. The Moon is Slowly Drifting Away from Earth: Every year, the Moon moves approximately 1.5 inches (about 3.8 centimeters) away from Earth. This gradual movement is caused by tidal forces — the same forces that cause ocean tides on Earth. Over millions of years, this could significantly alter the length of our days.😲😲😲 2. The Moon has Quakes: Just like Earth has earthquakes, the Moon experiences moonquakes. These are caused by various factors, including tidal forces exerted by Earth and thermal expansion as the Moon's crust warms and cools. Moonquakes can last up to an hour, much longer than typical earthquakes. 3. The Moon is Not Perfectly Round: The shape of the Moon is not a perfect sphere. It is slightly egg-shaped, with the larger end pointing towards Earth. This shape is influenced by gravitational forces between the Earth and the Moon. 4. The Moon Has an Atmosphere: While the Moon's atmosphere is incredibly thin compared to Earth's, it does exist. Known as an exosphere, it is composed of sparse particles, including helium, neon, and hydrogen. This atmosphere is so thin that molecules in it rarely collide, making it almost a vacuum. 5. The Moon's Surface is Covered in Dust and Rocks: The Moon's surface is covered by a layer called regolith, which consists of dust, soil, and broken rocks. This layer is the result of billions of years of impacts from meteoroids, asteroids, and comets. The lack of atmosphere means no weathering, so the surface remains largely unchanged over time.

No more than a year ago #India landed on the #Moon being the 5th nation achieving this goal. 1. The mission showed no evidence of water on the surface of the Moon. 2. The mission detected a Moon #quake 3. The mission finally gave us insight on how the temperature changes below the moon surface. The Chandrayaan-4 mission is coming soon(ish). On 2028 India will be back to the #Moon to collect samples and bring them back to #Earth. These samples will help study the origin, evolution, and composition of the Moon.

Blood moon 🩸🌕 One meaning of a "blood moon" is based on its red glow. This blood moon occurs during a total lunar eclipse. During a total lunar eclipse, Earth lines up between the Moon and the Sun. This hides the Moon from the sunlight. When this happens, the only light that reaches the Moon's surface is from the edges of the Earth's atmosphere. The air molecules from Earth's atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon's surface with a red glow, making the Moon appear red in the night sky. The name "blood moon" is also sometimes used for a Moon that appears reddish because of dust, smoke or haze in the sky. And it can be one of the full moons of autumn when the leaves are turning red. Source: https://lnkd.in/d9y3dfTb The next visible blood moon is scheduled for March 13/14, 2025, providing a spectacular sight across various global regions. The moon's color can vary based on pollution and cloud cover.
