Astronomers using data from the NASA/ESA Hubble Space Telescopes and other telescopes have performed an accurate census of the number of galaxies in the Universe. The group came to the surprising conclusion that there are at least 10 times as many galaxies in the observable Universe as previously thought. The results have clear implications for our understanding of galaxy formation, and also help solve an ancient astronomical paradox — why is the sky dark at night?

Did you hear that the Universe has 10x the number of galaxies? How did astronomers discover this, and what does it mean for the number of stars?
How many galaxies are there in the Universe? Recent estimates tell us that there could be as many as two trillion galaxies in
It is estimated that there are between 200 billion (2×1011) to 2 trillion galaxies in the observable universe. Most galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3,000 to 300,000 light years) and are separated by distances on the order of millions of parsecs (or megaparsecs).How many solar systems are in a galaxy? ›
The latest data collected by NASA indicates that there are 3,916 solar systems within our Milky Way. This means there are 3,916 stars with planets orbiting them in our single galaxy. Also according to the latest data, there are 5,241 confirmed exoplanets, which are planets that exist outside our solar system.Is the universe Endless? ›
The universe may be infinite, but we can only analyze a finite part of it (the part in which light has had time to reach us). As far as we can see, there are galaxies in every direction with no sign of slowing down. We've seen no sign of an edge of the universe.Are there 12 galaxies? ›
There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe.Is it possible to travel to another galaxy? ›
Intergalactic travel is the hypothetical crewed or uncrewed travel between galaxies. Due to the enormous distances between the Milky Way and even its closest neighbors—tens of thousands to millions of light-years—any such venture would be far more technologically and financially demanding than even interstellar travel.What is bigger than a galaxy? ›
The Universe is the biggest when compared to a galaxy or the Solar System.What is our universe called? ›
Universe is a name given to all the matter around us. Our universe is also called the cosmos. It is originally a greek word. In early days it was thought that our Galaxy constituted the entire universe.Is there living things in other planets? ›
Despite a lot of research in outer space, scientists have not yet been able to find evidence of life forms on any other planet other than Earth. Earth is very hospitable, which makes living here easy. Earth has water, which living creatures need to survive.Which is the biggest planet in the Milky Way? ›
Jupiter is more than twice as massive than the other planets of our solar system combined. The giant planet's Great Red Spot is a centuries-old storm bigger than Earth.
Thus, everything that has existed still exists, and everything that will exist already exists, just not in the state(s) it did or is going to. And even if time is infinite you would not be born again. An exact copy of you might have existed or might exist in the future, but not exactly you.What exists beyond universe? ›
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.Who created the universe? ›
According to the Book of Genesis, God created the universe - and all the heavenly bodies, the sun, the moon, and the stars - in six days. But according to contemporary cosmologists the universe began with a great explosion known as the Big Bang, after which the stars and galaxies slowly formed over billions of years.Which galaxy is Earth in? ›
Earth is in the second largest galaxy of the Local Group - a galaxy called the Milky Way. The Milky Way is a large spiral galaxy. Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy.How many Earths are there in the universe? ›
One 2020 study that analysed Kepler data calculated that the Milky Way could harbour as many as six billion Earth-like planets, while another estimated the number of potentially habitable planets in our galaxy at about 300 million.How many universes are in space? ›
We currently have no evidence that multiverses exists, and everything we can see suggests there is just one universe — our own.How many universes are there ever? ›
The most exciting part of asking, “how many universes are there” is that there isn't a concrete answer yet. Multiverses are theoretically possible within our understanding of physics. It's highly unlikely that real alternate universes match most pop culture multiverses.Are there 12 universes? ›
The Twelve Universes (１２の宇宙, Jūni no Uchū), also called Multiverse referred to twelve massive celestial bodies which contain the entirety of the Dragon Ball multiverse, that exists into one singular universe. There were formerly eighteen universes but six of them were destroyed by the Zen'ō when he was angered.How many universes could exist? ›
The number of possible parallel Universes tends to infinity, but does so at a particular (exponential) rate, but the number of possible quantum outcomes for a Universe like ours also tends to infinity, and does so much more quickly.What is beyond the universes? ›
The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.
