Kurzgesagt – In a Nutshell: Neutron Stars – The Most Extreme Things that are not Black Holes

⭐️Neutron Star Facts⭐️ ✨Mainly made up of neutrons, neutron stars are incredibly small, super dense stars with a solid crust made of iron and similar elements. ✨Although neutron stars weigh as much as the sun, they are just 20km across on average. ✨A tablespoon of neutron star would weight one milion tonnes. ✨Neutron stars form from the central core of a star that has died in a supernova explosion. ✨To produce a neutron star, a star must be more than 1.4 times as massive as a medium size star, such as the sun. This is chandrasekhar limit. ✨A star more than 3 times as massive as the sun would collapse beyonda neutron star to form a black hole. This is called the Oppenheimer- Volkoff limit. ✨The first evidence of neutron star came when pulsars were discovered in 1960s. ✨Some stars giving out X-ray, such as Hercules X-1, are neutron stars. The X-rays come from nearby stars as material is squeezed on to their surfaces by their gravity. ✨Neutron stars have a very powerful magnetic feilds, billion of times stronger than the earth's, which stretch the atoms out into frizzy 'whiskers' on the star's surface. @LAQMC

Fraser Cain: What Is A Quasar?

⭐️Facts about Quasars⭐️ ✨The most intense sources of light in the universe, quasars are no bigger than solar system, but they glow with the brightness of 100 galaxies. ✨Quasars are the most distant known objects in the universe. Even the nearest is billion of light years away. ✨The most distant quasar is on the very edge of the known universe, 13 billion light year away. ✨Some quasars are so far away that we see them as they were when the universe was still in its infancy less than 10 percent of its current age. ✨Quasar is a short for Quasi-stellar (starlike) radio source. This comes from the fact that the first quasar were detected by the strong radio signal they give out, and also because quasars are small and bright that at first people thought they look like stars. ✨Less than 10 percent of the 100,000 quasars now known actually beam out radio signals. ✨The brightest quasar, 3C 273, is 2.5 billion light year away. ✨Quasars are at the heart of some galaxies called 'active galaxies'. ✨The energy used by quasars comes from a black hole at their core, which draws matter ferociously. ✨The black hole at the core of a quasar may have the same mass as 100 million suns. @LAQMC

⭐️ Black hole Facts⭐️ ✨Gravity is so strong in Black holes that it sucks everything in, including light. ✨If a human fell in to Black hole, they would stretch like spaghetti. ✨When a star or Galaxy becomes so dense that is collapses under the pull off its own gravity, Black holes created. ✨Gravity shrinks a Black hole to unimaginably small point called singularity. ✨Around a singularity, is so dense that space-time is bent into a funnel. ✨Matter spiralling in to a Black hole is torn apart and glows so brightly that it creates the brightest objects in the universe quasars. ✨The swirling gases around a Black hole turn in to electrical generator, spouting jets containing electrons that are billions of kilometers out in to space. ✨The opposite of black holes may be white holes, which spary out matter and light like fountains. ✨Black holes and white holes may join to form tunnels called worm holes. ✨The gravity of a black hole is so strong that nothing can escape, not even light. Planets, stars, gas and dust are pulled in to the hole. @LAQMC

To stay alive, some sharks have to swim constantly forward For some sharks, like the great white and the mako, there’s no time to stop swimming. They have to keep on the move to stay alive. All sharks take oxygen from water so they can breathe. But sharks like these ones can’t pump water over their gills. So to stay alive, the sharks have to constantly swim forward. This keeps water filtering through their gills, so they’re always taking in oxygen to breathe. Share & join @biozooo @biozooo @biozooo
