what is past the solar system？
The Short Answer: Beyond our solar system lies the Oort cloud. The Oort cloud is made of icy pieces of space debris the sizes of mountains and sometimes even larger.
Besides,What's past our solar system?
Exoplanets are planets beyond our own solar system. Thousands have been discovered in the past two decades, mostly with NASA's Kepler Space Telescope. These worlds come in a huge variety of sizes and orbits. Some are gigantic planets hugging close to their parent stars; others are icy, some rocky.Exoplanets: Worlds Beyond Our Solar System - Space.comhttps://www.space.com › 17738-exoplanetshttps://www.space.com › 17738-exoplanets网页快照
Correspondingly,What is beyond our galaxy?
Our star's gravity also extends well beyond the heliosphere, holding in place a distant, sparse sphere of ice, dust, and space debris known as the Oort Cloud.The weird space that lies outside our Solar System - BBC Futurehttps://www.bbc.com › future › article › 20200908-the-...https://www.bbc.com › future › article › 20200908-the-...网页快照
One may also ask,Have we sent anything beyond our solar system?
No spacecraft has gone farther than NASA's Voyager 1. Launched in 1977 to fly by Jupiter and Saturn, Voyager 1 crossed into interstellar space in August 2012 and continues to collect data. Voyager 1 and its sister ship Voyager 2 have been flying longer than any other spacecraft in history.In Depth | Voyager 1 - NASA Solar System Explorationhttps://solarsystem.nasa.gov › missions › in-depthhttps://solarsystem.nasa.gov › missions › in-depth
Also asked,What is beyond the planets and stars?
The universe is a vast expanse of space that contains all of everything in existence. The universe contains all of the galaxies, stars, and planets. The exact size of the universe is unknown. Scientists believe the universe is still expanding outward.Overview | Beyond Our Solar Systemhttps://solarsystem.nasa.gov › solar-system › overviewhttps://solarsystem.nasa.gov › solar-system › overview网页快照

Is it possible to leave our galaxy?
So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre. We'd need to go much further to escape the 'halo' of diffuse gas, old stars and globular clusters that surrounds the Milky Way's stellar disk.How far would we need to travel to leave our Galaxy?https://www.sciencefocus.com › space › how-far-would-w...https://www.sciencefocus.com › space › how-far-would-w...
Will Voyager 1 ever stop?
Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020.Frequently Asked Questions - Voyager - NASAhttps://voyager.jpl.nasa.gov › frequently-asked-questionshttps://voyager.jpl.nasa.gov › frequently-asked-questions
Will Voyager 1 leave the Milky Way?
It is doubtful that the spacecraft will ever be able to leave the Milky Way, as they would have to attain a velocity of 1000 kilometers/second, and unless they get a huge, huge, huge velocity boost from something unexpected, they will probably end up being in the Milky Way's rotation forever.Will the Pioneer and Voyager probes ever leave the Milky Way?

How many universes are there?

Can the universe be infinite?
If the universe is perfectly geometrically flat, then it can be infinite. If it's curved, like Earth's surface, then it has finite volume. Current observations and measurements of the curvature of the universe indicate that it is almost perfectly flat.Is there anything beyond the universe? - Space.comhttps://www.space.com › whats-beyond-universe-edgehttps://www.space.com › whats-beyond-universe-edge
How does universe end?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.Crunch, rip, freeze or decay — how will the Universe end? - Naturehttps://www.nature.com › articleshttps://www.nature.com › articles
