How many stars are in the universe? In the observable universe there are about 10 billion galaxies.  Assuming galaxies have an average of 100 billion stars each, the  observable universe has about 1 billion tr…illion stars (or  1,000,000,000,000,000,000,000).

There may be 10 times more galaxies in the universe than we thought There may actually be 10 times more galaxies in the universe than we previously thought. Before today, the best estimate of the number of galaxies existed in the universe came from a 1995 observation by Hubble, shortly after it was repaired in orbit. That’s when NASA used the space telescope to observe a patch of sky continuously for 10 days.

- For those of you not in the know, arrachera is a very tender and juicy Mexican specialty cut of meat that is normally served grilled. Arrachera meat is a muscle between the thorax and the abdominal cavity that includes the diaphragm. In other markets this cut of beef is called Boneless Beef Plate Skirt Steak.

How Many Stars Are In The Universe? Kornreich used a very rough estimate of 10 trillion galaxies in the universe. Multiplying that by the Milky Way's estimated 100 billion stars results in a large number indeed: 100 octillion stars, or 100,000,000,000,000,000,000,000,000,000 stars, or a 1 with 29 zeros after it.ome estimates peg the Milky Way's star mass as having 100 billion solar masses, or 100 billion times the mass of the sun. Averaging out the types of stars within our galaxy, this would produce an answer of about 100 billion stars in the galaxy.

Bright Hub Our galaxy, the Milky Way, contains over 100 billion stars. The universe has more than 100 billion galaxies with each galaxy containing an average of 100 billion stars. Well, you can just imagine the number of stars in the entire universe. Just like human beings and animals, stars have their own life cycles.

- For the Universe, the galaxies are our small representative volumes, and there are something like 10 11 to 10 12 stars in our Galaxy, and there are perhaps something like 10 11 or 10 12 galaxies. With this simple calculation you get something like 10 22 to 10 24 stars in the Universe.

Scientists Estimate 20 Billion Earth-Like Planets In Our Galaxy Andrew Howard, one of the study's co-authors, enthused at a recent news conference that their 22 percent figure means that with about 100 billion stars in our Milky Way galaxy, that's about 20 billion such planets. ... And, that's just in a single galaxy.

- Of the 5,000 to 8,000 stars in the Milky Way visible to the human eye from Earth, one can usually only see about 2,500 at a time. In fact, the few thousand stars we can see of the Milky Way with our naked eye are only about 0.000003% of the 200-400 billion stars that inhabit the spiral! [source]

How Many Planets Are In The Universe? Our Sun is just one of an estimated two-to-four hundred billion stars in our Milky Way galaxy, and looking up towards the night sky, one can’t help but wonder how many of those stars have planets of their own, and what those worlds are like.

How many galaxies are there in the world? Best Answer: Your question is in astronomy, so I assume that you do not want the total number of Ford Galaxies on the surface of the planet. There are probably more than a hundred billion (10^11) galaxies in our visible universe. Check out the site below: Source(s): http://www.atlasoftheuniverse.com/univer...

Galaxy Approximately 170 billion (1.7 × 1011) to 200 billion (2.0 × 1011) galaxies exist in the observable universe. Most of the galaxies are 1,000 to 100,000 parsecs in diameter and usually separated by distances on the order of millions of parsecs (or megaparsecs). The space between galaxies is filled with a tenuous gas with an average density less than one atom per cubic meter.

Star Most stars are between 1 billion and 10 billion years old. Some stars may even be close to 13.8 billion years old—the observed age of the universe. The oldest star yet discovered, HD 140283, nicknamed Methuselah star, is an estimated 14.46 ± 0.8 billion years old.

How Many Stars Are in the Milky Way? In the end, it comes down to an estimate. In one calculation, the Milky Way has a mass of about 100 billion solar masses, so it is easiest to translate that to 100 billion stars. This accounts for the stars that would be bigger or smaller than our sun, and averages them out.Other mass estimates bring the number up to 400 billion.illions and billions of stars in a galaxy (after a quote often mistakenly attributed to Carl Sagan) is how many people imagine the number of stars you would find in one.

- 1 There are around 200 billion stars in the Milky Way alone. 2  VY Canis Majoris is the largest known star in our galaxy, if this star was in the center of our solar system its outer atmosphere would reach the orbit of Saturn. 3  One of the smallest known stars in our galaxy is VB 10, it is only around 20% larger than Jupiter.

How Many Stars are There in the Universe? Because the universe was born 13.8 billion years ago, we can only observe objects up to a certain distance from Earth — light from more distant objects hasn’t had time to reach us yet. And to answer “how many stars are there,” we must limit the discussion to what we can observe. Astronomers estimate that the observable universe has more than 100 billion galaxies. Our own Milky Way is home to around 300 billion stars, but it’s not representative of galaxies in general.

The Stars of the Milky Way Image of the Milky Way taken at 1996. Texas Star Party. Our galaxy, the Milky Way, contains maybe 400 billion stars (plus or minus 200 billion) that lie mostly in a flattened spiral disk of some 70-100,000 light-years (ly) across, with a central bulge of about 10,000 ly in diameter.

How We Know How Many Galaxies Are In The Universe, Thanks To Hubble And given that there are hundreds of billions of star within our own galaxy, that teaches us there are some 10^23 stars in the Universe, each one with their own unique story, history, planetary systems, and just possibly a chance at life. So on your 25 anniversary, for all that you’ve done, thank you, Hubble.

How many galaxies are there in the universe? Galaxies — those vast collections of stars that populate our universe — are all over the place. Perhaps the most resonant example of this fact is the Hubble eXtreme Deep Field, a collection of photographs from the Hubble Space Telescope revealing thousands of galaxies in a single composite picture.

How Many Galaxies Are There? Livio pointed out there could be galaxies in these other universes — if they exist — but we have no way right now of knowing for sure. So the number of galaxies could even be greater than 200 billion, when considering other universes. In our own cosmos, Livio said, astronomers will be better able to refine the number upon the launch of the James Webb Space Telescope (for which his institute will manage the mission operations and science).

How Many Galaxies Are There in the Universe? The Redder We Look, the More We See If you assume that the XDF is a typical region of outer space, you can calculate how many XDFs it would take to fill the entire night sky; it’s about 32 million. Multiply by the number of galaxies you find in the XDF—which is around 5,500—and that’s how we arrive at 176 billion galaxies, at least, in the Universe.

How many stars are there in sky? Well, if there's between 200 - 400 billion stars in our milky way we can probably get an approximate figure by assuming a few things. Firstly, we need to assume that all galaxies contain the same amount of stars, and we need to assume we know how many galaxies are out there.

How Many Galaxies Are There in the Universe? The Redder We Look, the More We See But there are maybe 75% more galaxies-per-patch-of-sky in the XDF! Applying the XDF results to the entire sky, we find that there are more like 176 billion galaxies in the entire Universe, a huge increase from our previous estimate from the HUDF.

- There are in fact 100 billion galaxies, each of which contain something like a 100 billion stars. Think of how many stars, and planets, and kinds of life there may be in this vast and awesome universe..

How Many Stars Are in the Universe? Multiplying the number of galaxies — which is about 2 trillion — by the 100 million stars in the galaxy suggests there could be about 10 raised to the19th power stars in the universe, Conselice said. But this could easily be a factor of 10 higher, Conselice said. Jeanna Bryner contributed reporting to this article.
