A guess: Carl Sagan.
After the Milky Way galaxy, there are many other galaxies in the universe. Some of the closest galaxies to us are the Andromeda galaxy and the Triangulum galaxy. Beyond these, there are billions of other galaxies in the universe, each containing billions of stars.
No, the Andromeda Galaxy is not bigger than the universe. The universe is vast and contains billions of galaxies, including the Andromeda Galaxy. The universe is much larger in scale and encompasses everything that exists.
No-one can possibly know for sure, but the answer is probably billions. There are hundreds of billions of stars in our own Milky Way galaxy, many of which have solar systems of their own, and as many galaxies in the Universe as there are stars in our own galaxy (and the Milky Way is by no means a particularly large galaxy, just of average size). If you take all of this into account, the number of planets likely to be in the universe would be many billion.
There is no singular star in the center of the universe. Our universe is vast and does not have a center. Stars are spread throughout the universe in galaxies, and our sun is just one of the billions of stars in the Milky Way galaxy.
A universe is the entire system of all matter and energy that exist, including galaxies, while a galaxy is a massive collection of stars, gas, dust, and dark matter held together by gravity. Galaxies are just one component of the universe, which contains all galaxies, stars, planets, and other cosmic entities.
Like our galaxy contains billions of stars, the universe contains billions of galaxies.
After the Milky Way galaxy, there are many other galaxies in the universe. Some of the closest galaxies to us are the Andromeda galaxy and the Triangulum galaxy. Beyond these, there are billions of other galaxies in the universe, each containing billions of stars.
A galaxy contains billions of stars. A universe contains billions of galaxies.
universe is largest. universe is made up of billions of galaxies.
The galaxy, the one we are in, we call the Milky Way. It is one of billions of galaxies. These galaxies and everything else make up the universe. Compared to the universe galaxies are small fry.
No. The universe contains billions of galaxies including our own, and each galaxy contains billions of stars.
Yes. The Milky Way is just one galaxy. There are billions of galaxies in the known universe.
..What..? The univere is EVERYTHING, including the milky way galaxy.
No. The Milky Way galaxy is just one of billions of galaxies in the Universe. Just like there are billions of planets in the Milky Way Galaxy, there are also comparable numbers of planets in other galaxies.
More planets. A typical galaxy probably has billions of planets.
Not just hundreds of millions. The observable universe contains hundreds of billions of galaxies.
The Milky Way is the galaxy in which the solar system is located. It is a barred spiral galaxy that is part of the local group of galaxies. It is one of billions of galaxies in the observable universe.
