4 billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda.
Currently, Andromeda and the Milky Way are about 2.5 million light-years apart. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour. But even at that speed, they won’t meet for another four billion years. Then, the two galaxies will collide head-on and fly through one another, leaving gassy, starry tendrils in their wakes. For eons, the pair will continue to come together and fly apart, scrambling stars and redrawing constellations until eventually, after a billion or so years have passed, the two galaxies merge.🔭 Are you ready to explore Space 🔭 @theourspace

If the Moon replaced the @iss 😨 Via 👉 @watcrateofficial
“If the Moon was at the same distance as the @ISS - just 420 kilometers (260 miles) away from us.
😨 - probably one of my favorite @yetidynamics videos ever.
Normally the Moon orbits much slower than the earth rotates so it rises in the east and sets in the west, however at 420km it orbits much faster, faster than the earth rotates underneath (1 full rotation: 90 mins), therefore it will rise in the west and set in the east.
Via Phil Plait @thebadastronomer "The Moon would fill more than half the sky. It would also appear to rotate, although it would actually still be tidally locked to our planet like it currently is. And some Earthlight would reflect onto the Moon, except for where the Moon blocks the Sun. It would cross the sky in very roughly five minutes!"
Of course, in reality, if the Moon was actually this close it would break apart due to gravitational forces and bye bye Humans.

Günaaydııınnn!! Saat 6.30 ve fizik-II' den geçme umutlarım gittikçe tükeniyor. Gerçekten bunu nasıl anlıyosunuz? Lisede de hep geçer notu almak için çırpınıyordum. Dün saat 21. 00 gibi başladım ama hâlâ inatla bitiremiyorum üstelik saat 11. 00 de final var.🤦🏻♀️
