The world is thought about by part to it is in infinite, while others find comfort in the truth that the may have an end. Transparent the ages of room exploration, the only details thing is possibly the fact that the universe will never ever be charted.

You are watching: How many galaxies are there in our universe

Why is this? It’s because of the countless galaxies the seem to pop out left and also right, their sizes, distances, and also other aspects. Therefore how countless galaxies space there in the Universe? Currently, the observable Universe, which has a radius of 46.5 exchange rate light-years, seems to save at the very least two sunshine galaxies.

*

Our galaxy, the Milky Way, is just one amongst these many galaxies, and also it isn’t even considered a huge galaxy. That stretches for 105,700 light-years in diameter and also may contain at least 100 billion planets and also around 400 exchange rate stars.

Now, if us were come imagine how plenty of planets and also stars those 2 trillion galaxies can have, we would probably need to throw the end our calculators. This is specifically true due to the fact that some galaxies are number of times larger than ours Milky means Galaxy.

Largest Galaxy ever before Discovered

The largest galaxy ever found in our universe is the supergiant elliptical galaxy designated together IC 1101. This galaxy contains well over 100 trillion stars, and it stretches for over 5.5 million light-years across.

*

IC 1101 is roughly 50 times larger than our Milky method Galaxy, and it is situated at about 1 billion light-years / 320 megaparsecs away from us. 

How countless Galaxies are there in the Milky Way?

Our own Milky method has part satellite galaxies, which space very tiny galaxies that space gravitationally tied to bigger ones. These small galaxies have actually been or room in the procedure of gift integrated/devoured by their bigger brethren.

*

The Milky means galaxy has actually satellite galaxies such as the big and little Magellanic Clouds. There are approximately fifty galaxies in the Milky Way, the biggest of i beg your pardon is the huge Magellanic Cloud. This satellite galaxy has a diameter of just 14,000 light-years.

The large Magellanic Cloud may have as countless as 10 exchange rate stars within it. This small galaxy will collide v our Milky way in about 2.4 billion years.

How numerous Galaxies room there in the cosmos 2020?

Currently, in 2020, it was approximated that there are about 2 trillion galaxies in the observable Universe. Each galaxy is unique, ranging in size from 10,000 light-years to thousands of light-years.

*

Galaxies have been divide under five categories: spiral, barred spiral, lenticular, elliptical, and irregular. Our Milky means galaxy is a barred spiral galaxy.

Is the Milky method a big Galaxy?

The Milky method is taken into consideration an average-sized galaxy. The stretches because that 105,700 light-years in diameter and may contain at the very least 100 billion planets and around 400 exchange rate stars.

*

Now, if the Milky means is an mean galaxy, just how does a large galaxy watch like? Well, it would prefer IC 1101, i m sorry is currently the largest galaxy ever discovered.

IC 1101 is much more than 50 times larger than the Milky Way. That stretches because that over 5.5 million light-years across. This galaxy may have trillions that stars and planets.

Can human beings Travel to an additional Galaxy?

Humans can travel to various other galaxies, yet the modern technology involved would certainly look an extremely different from what we currently have. Galaxies room thousands or also millions that light-years far from one another; the street is practically unfathomable.

The required technology for intergalactic travel is far beyond our existing capabilities. They are largely on the topic of speculation, hypothesis, or scientific research fiction.

Reaching the rate of light is an essential for intergalactic space travel, and also this presents its very own problems and limits. Even if us were to travel at the rate of light, it would certainly still take us hundreds of years, in the best case, to reach one more galaxy.

*

Take, because that example, the big Magellanic Cloud, which is among the the next galaxies come our Milky Way. This little and young galaxy is located at around 158,200 light-years away from us.

Thus, it would take you 158,200 years to with it, and also this indicates traveling in ~ the speed of light constantly, which additionally creates numerous problems.

We would require an countless amount of power to perform so, and also we’ve not even started to talk about food or water resources. Together we have the right to see, water is quite tough to find on other celestial objects.

Where would certainly we get water on together trips? and also heck, water is simple to find compared to food. Wherein would we uncover food while traveling to various other galaxies?

As you have the right to see, there room so plenty of problems when it comes to intergalactic travel that it may seem impossible; however, we might one day make it possible.

There may be far better options for mankind to travel in an are then just with the speed of light. If these choices remain only purely hypothetical, such as the much-coveted wormholes, then we are indeed trapped in ~ our very own galaxy.

Another facet we have to take into consideration is the truth that galaxies relocate around, just like planets, and stars do. It has been proven that countless galaxies are acquiring further and further away from us.

If us would want to reach various other galaxies, our ideal chance is to go directly towards a galaxy i beg your pardon is comes our way, favor the Andromeda Galaxy, because that example.

The Andromeda Galaxy is on a collision course with our Milky way Galaxy; however, this will take place in roughly 4.5 billion years from now. This number is far too an excellent to help us in our intergalactic an are travel endeavor.

How many Universes are There?

Since the universe is so substantial and complex, one might assume that various other Universes exist. Over there is just one cosmos we at this time know of, and that is the universe in which we already live.

The existence of other Universes definitely seems possible; however, we are still ~ above the procedure of examining our own prior to hunting because that others.

We recognize too tiny about our own Universe, and deciphering that is the crucial to finding out if there are various other Universes the end there.

Did you Know?

It is thought that the Milky way galaxy has about two rogue planets because that every star. They space planets that have been thrown out of their solar system. This can occur through collisions, or if their sunlight underwent a stellar evolution and lost its grip on them.The outermost regions of the Milky way suggest the it hasn’t undergone any kind of mergers with large galaxies in the last 10 billion years. Galaxies such as the Sombrero Galaxy demonstrate that a galaxy’s size could not necessarily yield a better or lesser number in stars.Sources:Image Sources:
