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

In a groundbreaking discovery, astronomers have finally detected a rocky exoplanet beyond our solar system with an atmosphere—a crucial characteristic for assessing its potential habitability. However, this newly found "super-Earth" offers no hope for sustaining life due to its extreme conditions. Named 55 Cancri e or Janssen, this planet orbits perilously close to its host star, completing an orbit every 18 hours. With a surface primarily composed of molten rock, its surface temperature reaches a scorching 3,140 degrees Fahrenheit (1,725 degrees Celsius). Despite its inhospitable environment, infrared observations from the James Webb Space Telescope indicate the presence of a substantial atmosphere, likely enriched with carbon dioxide, carbon monoxide, water vapor, and sulfur dioxide. The exact composition and thickness of the atmosphere remain undetermined, posing intriguing questions about its origin and stability. This discovery marks a significant milestone in exoplanet exploration, as previous detections of atmospheres primarily involved gas giants rather than rocky planets. While 55 Cancri e may not support life, the insights gained from studying its atmosphere contribute to our understanding of planetary formation and evolution. Stay tuned for further updates as astronomers continue to explore the cosmos, uncovering the mysteries of distant worlds and expanding our knowledge of the universe. #Astronomy #Exoplanet #AtmosphereDetection #SpaceExploration #Habitability #55Cancrie #SuperEarth #JamesWebbSpaceTelescope #Astrobiology #ScienceNews #NASA #PlanetaryScience #Astrophysics

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

Metal Scar Found on Cannibal Star WD 0816-310 | European Southern Observatory FriendsofNASA.org: Using European Southern Observatory’s Very Large Telescope (VLT), astronomers have found a metal ‘scar’ imprinted on the surface of a dead star. This video summarizes the discovery. When a star like our Sun reaches the end of its life, it can ingest the surrounding planets and asteroids that were born with it. This seems to be the case of the white dwarf WD 0816-310, the Earth-sized remnant of a star similar to, but somewhat larger than, our Sun. The scar the team observed is a concentration of metals imprinted on its surface. These metals seem to originate from a planetary fragment as large as or possibly larger than Vesta, which is about 500 kilometers across and the second-largest asteroid in the Solar System.

Beyond the Speed of Light: Exploring the Black Hole Event Horizon | Aakash Khurana A black hole event horizon is a fascinating and mysterious boundary surrounding a black hole. #blackhole #eventhorizon #space #cosmos #astronomy #astrophysics #science #physics #universe #gravity #singularity #mystery #exploration #spacetime #darkmatter #darkenergy #blackholemovie #sciencedocumentary #educational #spacefacts #science #research #nasa Here's a breakdown: Imagine a cosmic speed limit: Imagine the speed of light as the ultimate speed limit in the universe. Nothing can go faster than light. The point of no return: Now, picture a massive object whose gravity is so strong that even light can't escape its pull. That point where escape velocity becomes greater than the speed of light? That's the event horizon. It's not a physical surface: Although we often call it a "surface," the event horizon isn't like a solid object. It's more like a mathematical boundary defining the region where escape is impossible. One-way trip: Once something crosses the event horizon, it's stuck inside the black hole forever. We can't observe anything happening beyond that point, making it a true mystery. What happens there? We don't have a complete picture of what happens inside a black hole, but based on our understanding of physics, matter likely gets crushed and squeezed toward a central point called the singularity. However, this is an area of ongoing research and there might be surprises in store. Key points to remember: Event horizon = boundary where escape velocity exceeds light speed. It's not a physical surface but a mathematical boundary. Nothing, not even light, escapes from inside. What happens inside remains a mystery. I hope this explanation helps! If you have any further questions about black holes or event horizons, feel free to ask. for more info: https://lnkd.in/gwUmGTkY

Strongest statistical evidence yet suggests the existence of Planet Nine, a giant planet lurking in the far reaches of our solar system. 🪐 Konstantin Batygin (Caltech) and his team analyzed the movements of unstable Trans-Neptunian Objects (TNOs) – celestial bodies beyond Neptune's orbit. **Key takeaways:** * Researchers factored in gravitational forces from other planets, passing stars, and even the Milky Way's influence. * Simulations showed the TNOs' movements align with the presence of Planet Nine. * New telescopes like Vera C. Rubin Observatory will enhance the search. While conclusive proof is still pending, this research significantly bolsters the case for Planet Nine.

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.

A rare exoplanet defying current models. Researchers led by Sam Grunblatt at the Johns Hopkins University, using the Transiting Exoplanet Survey Satellite (TESS), have found out an exoplanet defying what we thought we knew about these objects. TIC 365102760 b, also known as Phoenix, belongs to the hot Neptunes class, and it's located around 1800 light-years from us. What makes it so rare if the fact that despite its proximity to its host star, instead of being a bare rock, it still keeps its atmosphere. Furthermore, it's also smaller, older and hotter than current models' predictions for such objects. Phoenix has been estimated to be 10000 million years old, but after studying its orbit, the team calculated that it will fall into the star in approximately 100 million years. The findings have been published in The Astrophysical Journal (5 June, 2024). https://lnkd.in/dYr4iMDN #physics #physicsnews #astrophysics #astronomy #tess #exoplanet #exoplanets #phoenix #hotneptune #TIC365102760b #TIC365102760
