Building Worlds: The Process of Planetary Formation 🌍✨ 1. Nebula Collapse 🌟 Large clouds of gas and dust (nebulae) collapse under gravity. 💫 Triggered by events like supernova explosions or collisions with other clouds. 2. Protoplanetary Disk Formation 🌀 🌌 The collapsing nebula flattens into a spinning disk around a new star. 🌠 The central region forms a protostar, while the outer regions become the protoplanetary disk. 3. Accretion of Planetesimals 🪨 🌑 Dust and gas particles within the disk collide and stick together. 🌍 These particles form larger bodies called planetesimals, which can be kilometers in size. 4. Formation of Protoplanets 🌏 🌋 Planetesimals collide and merge to form larger bodies called protoplanets. 🌠 Gravitational interactions cause them to clear their orbits and grow. 5. Differentiation and Core Formation 🪐 🌐 Protoplanets heat up, causing heavy elements to sink to the center and form cores. 🌟 Lighter elements remain in the outer layers, leading to differentiation. 6. Giant Impacts 🌑💥 🪨 Protoplanets may collide with each other, resulting in massive impacts. 🌕 These impacts can shape the final planets and form moons. 7. Clearing the Nebula 🌬️ 🌌 Stellar winds from the young star blow away remaining gas and dust. 🌠 Only solid bodies (planets, moons, asteroids) remain in the system. 8. Formation of Stable Orbits 🌌 🪐 Gravitational interactions stabilize the orbits of planets and other bodies. 🌍 Planets settle into orbits around the star, forming a stable planetary system. Conclusion 🌌✨ 🚀 Planetary formation is a complex process involving the collapse of nebulae, accretion of particles, and giant impacts. 🌟 This process creates the diverse worlds we observe in our solar system and beyond. #PlanetaryFormation #BuildingWorlds #NebulaCollapse #ProtoplanetaryDisk #Accretion #Planetesimals #Protoplanets #Differentiation #GiantImpacts #Astronomy #SpaceScience #CosmicFormation #SolarSystem #Exoplanets #Astrophysics

Two massive black holes collide after a gravitational dance. This is due to their extreme gravitational attraction. This event typically appears as a smooth merging process, without any visible explosion or dramatic effects. But they generate powerful gravitational waves that travel at the speed of light. These waves cause ripples in the fabric of space-time. During the propagation, they modify the distance between the masses distributed in spacetime, causing distortions in a perpendicular way. 🌐During the gravitational dance before merging, the gravitational distortion that alters the path of light is clearly seen. We begin to perceive the phenomenon of DOPPLER-BOOSTING / BEAMING and subsequently that of Gravitational Lensing. Neutron Stars Collision When two Neutron Stars or two stellar Black Holes collide and merge an explosion called Kilonova occurs. Kilonova is an explosion 100/200 and more powerful than a Supernova and many times more than a Hypernova. It happens when two super massive and ultra dense and compact objects ....usually binary Neutron Stars ... go into coalescence The reciprocal rotation increases more and more vertically until the collision. ☆•☆•☆ 🌐Credit each clip used in editing: MIT and NASA SVS 🌐VIDEO COMPOSITION AND EDITING BY @glamour_physics @modernsciencex #goatomico #atomico #go_atomico #physicsfacts #spacescience #nasa #whatif #blackhole #blackholes #alberteinstein #generalknowledge #spacefacts #universe #astronomy #astrophysics #neutronstar #astronomia #blackhole #blackholes #alberteinstein #generalknowledge #spacefacts

SCIENCEFEB 2, 2024 9:00 AM Why Is Our Solar System Flat? It started as a big old ball of dust, so how did it end up like a giant pancake? Our resident physicist tells the true story using fake forces. model of solar system Some of my favorite things to look for in the night sky (besides the International Space Station) are the planets. If you need help finding them, I recommend Heavens-Above. It's a website where you can enter your location and it will show you what's currently visible in your area. But one trick you can use on your own is to scan along the ecliptic. This is a line in the sky that arcs from one spot on the horizon to another, basically following the path that the sun travels from where it rises to where it sets. The cool thing is that the planets (and the moon!) also appear along this same line. Why are they in a line? It's because the solar system is flat. I know, last week I outlined two experiments you can do to prove that the Earth is not flat. But the solar system really is flat. All the planets and most of the asteroids orbit the sun in roughly the same plane, so that when you view them from Earth they line up neatly.

An exoplanet, or “extrasolar planet”, is a planet orbiting a star outside our solar system: thousands of them have been discovered, and statistically each star of the Milky Way could have at least one planet orbiting it. Studying exoplanets will not only help us understanding the planetary evolution of our own solar system, but could also provide us with new insights on the existence of life beyond the Earth. Having hundreds of thousands of planets also means that there are many possibilities that they are in the habitable zone around their star, like our planet with the Sun. By identifying planets with favorable conditions for life, we increase the chances of finding extraterrestrial life. Looking for signs of life thousands of light-years from earth is an extremely complex task: a new approach to it, interfacing chemistry and planetary physics, is described in this captivating paper: https://lnkd.in/dKzxAHTG #LifeDetection@GT #Nasa #ESA #SpaceExploration #Exoplanets

In the late 1980s, the Voyager 2 spacecraft snapped the “canonical” up-close images of Uranus and Neptune. In those views, Uranus was a pretty greenish-blue and Neptune appeared a deep azure color. It turns out that both planets are pretty close in color: a greenish-blue more akin to Uranus’s appearance. No, Uranus and Neptune haven’t swapped color values. It turns out that those images aren’t precise recordings of their actual colors. Planetary scientists re-examined the Voyager 2 images and compared them to more recent observations made with both space-based and ground-based observatories. Then they created a model of what the colors should be. After that, they re-processed the images to come up with a more “true color” view of each planet. The result is a more realistic view of both worlds. - - - #Space #neptune #uranus #spaceze #nasa #spaceship #spacex #spacestation #universe #astronomy #astronaut #stars #spaceshuttle #explore

A Solar Filament Erupts Image Credit: NASA's GSFC, SDO AIA Team Explanation: What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space, producing an energetic coronal mass ejection (CME). The filament had been held up for days by the Sun's ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth's magnetosphere, causing visible auroras. Loops of plasma surrounding the active region can be seen above the erupting filament in the featured ultraviolet image. Our Sun is nearing the most active time in its 11-year cycle, creating many coronal holes that allow for the ejection of charged particles into space. As before, these charged particles can create auroras. #PhoenixDelivers #sun #nasa

If you peer out into the space sharing Earth's general orbital vicinity around the Sun, you'll find a lot of rocks. We have counted, to date, more than 35,000 near-Earth objects: asteroids and comets that can sometimes enter our corner of the Solar System before swooping away again. It's thought that there might be many more out there, too. And a new study has found that up to 60 percent of them could be something fascinating – what are known as "dark comets" that once contained or still contained ice, locked up in their enigmatic rocky bodies. This, according to a team of astronomers led by Aster Taylor of the University of Michigan, could be an important clue about where Earth got its water, back when the Solar System was but a mewling cosmic babe. "We don't know if these dark comets delivered water to Earth. We can't say that. But we can say that there is still debate over how exactly the Earth's water got here," Taylor explains. “The work we've done has shown that this is another pathway to get ice from somewhere in the rest of the solar system to the Earth's environment." Free-roaming rocks within the Solar System can take several different forms. Asteroids and comets are the two most well-known, with asteroids being dry rocks, and comets being icy rocks that start to eject material when they move near the Sun and heat up. (Meteors are rocks that enter a planetary atmosphere, and meteorites are the chunks that fall to a planetary surface.) But within the two space rock categories, there's a lot of variation, and even some crossover between them. Dark comets are thought to be one type of hybrid, but we don't know a lot about them. A fuzzy 'coma' or atmosphere of gas and a tail produced by the sublimation of ice are not the only two characteristics that are diagnostic of cometary properties. Another characteristic is its acceleration. As a comet ejects material, that ejection gives the comet an additional push of propulsion beyond what you'd expect to see if the rock was just an asteroid experiencing only gravitational forces. In addition, this outgassing can speed up the spin of the comet. Full Article: https://lnkd.in/g4fb6sPZ #NEOs #DarkComets #SolarSystem Illustration of a dark comet.

Dark matter is the universe's shadowy enigma 🌌✨. Invisible and undetectable by light, it doesn't emit, absorb, or reflect any rays, making it a cosmic ghost 👻. Yet, this mysterious substance makes up about 85% of all matter in the #cosmos! Its presence is revealed not by sight, but by its #gravitational pull on #stars, #galaxies, and #light itself 🌠💫. Dark matter keeps galaxies from flying apart and bends the path of light, a phenomenon known as gravitational lensing 🌀. Despite making the universe work, its true nature is a massive puzzle 🧩 #scientists are eager to solve. From deep underground labs to telescopes peering into the universe's farthest edges, the hunt is on to uncover dark matter's secrets 🕵️♂️🔭. Will we unlock the cosmic shadows?
