Astronomical & Cosmological videos

✓ Why do we always see the same side of the Moon? • This phenomenon is due to a process known as tidal locking. • The Moon's rotation period is exactly the same as its orbital period around Earth. • This means that the Moon rotates on its axis once every 27.3 Earth days, which is also the time it takes to orbit Earth. • As a result, the same side of the Moon always faces Earth. . — Rizwan Ayub Saadi . #rizwanayubsaadi #earth #moon #planet #astronomy #astrophysics #space #spacetime...

✓ Earth speeding through potentially hazardous asteroids • Our home planet, Earth speeds through space surrounded by potentially hazardous asteroids. • Watch this animation showing the trajectories of our planet, other Solar System bodies, and the risks in our cosmic neighborhood. . — Rizwan Ayub Saadi . #rizwanayubsaadi #earth #planetearth #planet #astronomy #astrophysics #space #spacetime #asteroid #solarsystem #universe

✓ Europa and its friends orbiting Jupiter • This video showcases Europa, one of Jupiter's fascinating moons, and its celestial companions as they orbit the gas giant. • Watch as these moons participate in an intricate cosmic ballet. Additionally, • Europa is one of the four largest moons of Jupiter, known as the Galilean moons. • It's particularly intriguing to scientists because its icy surface is believed to cover a vast ocean beneath, making it a prime candidate in the search for...

✓ Martian moons cruising around the planet • Martian moons Phobos and Deimos gracefully orbiting their crimson planet—Mars, captured in motion. . — Rizwan Ayub Saadi . #rizwanayubsaadi #mars #phobos #deimos #moon #planet #space #spacetime #astronomy #astrophysics #universe

✓ How Saturn's rings formed. • Saturn's rings likely formed from the remnants of a moon or comet that was shattered by Saturn's strong gravitational forces. • This debris, made of ice and rock, spread out around the planet, forming the iconic rings seen today. • These rings are composed of countless particles, ranging in size from tiny dust grains to larger chunks. . — Rizwan Ayub Saadi . #rizwanayubsaadi #Saturn #rings #astronomy #astrophysics #galaxy #space #spacetime #universe

✓ Did you know ? - Earth orbits around the Earth-moon barycenter. But why? • It is because both Earth and Moon orbit their shared center of mass (barycenter) due to mutual gravitational forces, located beneath Earth's surface. • Moreover, the Earth orbits around the Earth-moon barycenter because both the Earth and Moon exert gravitational forces on each other, causing them to orbit their common center of mass. • This barycenter lies inside the Earth, about 4,671 km from its center, due...

✓ A black hole is not a hole! Moreover, • A black hole is not a hole in the classical sense, but a cosmic phenomenon where gravity is so intense that nothing, including light, can escape. • Formed by a massive star's collapse, it warps spacetime, creating a gravitational prison with an event horizon that marks the point of no return. • If it's not a hole then what this is; • Think of it as a singularity, a point of infinite density and zero volume, where the laws of physics are pushed...

✓ Today's video is a must-watch. • A recent study suggests that a black hole might pass through our solar system every decade. • However, the black hole in question would be so small that it poses no threat to our solar system. • The video highlights this phenomenon, showcasing a tiny black hole's passage without causing any significant damage or disturbance. . — Rizwan Ayub Saadi . #rizwanayubsaadi #blackhole #solarsystem #astrophysics #space #asteroid #gravity #astronomy #spacetime...

✓ Earth is never shown like this. • Our home planet, Earth as you've never seen it before—showcasing a unique perspective centered on Antarctica, a rarely highlighted region of our planet. . — Rizwan Ayub Saadi . #rizwanayubsaadi #earth #astronomy #astrophysics #planet #planetearth #space #antarctica #spacetime #universe

✓ Here's how much a neutron star bends spacetime around it. • This mind-bending visual shows the extreme curvature of spacetime around a neutron star! • Due to its incredibly dense mass, a neutron star warps the fabric of spacetime, creating an intense gravitational field that would stretch and compress anything nearby. • The closer you get, the more spacetime is distorted. Witness the awe-inspiring power of these cosmic wonders! . — Rizwan Ayub Saadi . #rizwanayubsaadi #neutronstar...

✓ The Whirlpool Galaxy and its satellite galaxy NGC 5195. • The Whirlpool Galaxy (M51) is a grand-design spiral galaxy located about 31 million light-years from Earth in the constellation Canes Venatici. • It is notable for its well-defined spiral structure and its interaction with a smaller satellite galaxy, NGC 5195. • This companion galaxy is believed to have passed through the Whirlpool Galaxy's disk, triggering star formation and enhancing the spiral arms. • The interaction between...

✓ Mind-bending truth! • This animation reveals how a neutron star warps the fabric of space around it. • Imagine a cosmic behemoth so dense that it bends the very essence of reality. • That's what a neutron star is - an incredibly dense celestial body formed from the remnants of a massive star. • With the mass of a sun compressed into a sphere only a few kilometers across, neutron stars possess gravitational pull so strong that not even light can escape once it gets too close. Witness the...

✓ Ever wanted to see how big a star can be? • Earth, sun and Stephenson 2-18 Additionally, • Stephenson 2-18 is a red supergiant or hyper giant star. • Stephenson 2-18 is one of the largest known stars in the universe by radius, located about 19,570 light-years away in the constellation Scutum. • It is a red supergiant, possibly a hypergiant, with an estimated size over 2,100 times the radius of the Sun—so massive that if placed at the center of our solar system, its surface would extend...
