Signs of second largest black hole in the Milky Way A study suggested that there are 100 million black holes in the Milky Way Galaxy, but X-ray observations have only found dozens so far. Most of the black holes may be “dark” and difficult to see directly at any wavelength.

How Many Stars Are In The Universe? Averaging out the types of stars within our galaxy, this would produce an answer of about 100 billion stars in the galaxy. This is subject to change, however, depending on how many stars are bigger and smaller than our own sun.Also, other estimates say the Milky Way could have 200 billion stars or more.The number of galaxies is an astonishing number, however, as shown by some imaging experiments performed by the Hubble Space Telescope.bservable universe. Even if we narrow down the definition to the observable universe — what we can see — estimating the number of stars within it requires knowing just how big the universe is. The first complication is that the universe itself is expanding, and the second complication is that space-time is curved.

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? There is no certain answer of this how many questions.The scientists estimate that there are between 100 – 300 billion galaxies are there in the observable universe.We dont know number of galaxies because they are just so far away that their light has not had time to reach us since the beginning of the universe.The universe is expanding since the ...

The Largest Black Hole In the Known Universe The most recent measurements indicate that there’s a supermassive black hole in here of 6.6 billion solar masses, a phenomenal number and again a mass that’s 1500 times as large as our Milky Way’s central giant! We can confirm this by studying the ejecta in the radio, from the VLA.

How many stars are there in sky? 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.

- As we learned in a previous video, there are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe – maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe – a 1 followed by 22 zeros.

Supermassive black holes are largest ever discovered Supermassive black holes are largest ever discovered. A figure depicting the immense size of the black hole discovered in the galaxy NGC 3842. Astronomers have located the two biggest black holes ever found, each one billions of times more massive than our sun. Observations of these supermassive cosmic objects will give scientists clues on how black holes and galaxies formed and evolved, especially in the earliest stages of the universe's existence.

Black Holes Black holes pull matter and even energy into themselves—but no more so than other stars or cosmic objects of similar mass. That means that a black hole with the mass of our own sun would not suck objects into it any more than our own sun does with its own gravitational pull.Planets, light, and other matter must pass close to a black hole in order to be pulled into its grasp.xtremely large black holes may exist at the center of some galaxies—including our own Milky Way. These massive features may have the mass of 10 to 100 billion suns. They are similar to smaller black holes but grow to enormous size because there is so much matter in the center of the galaxy for them to add.

The crust is only about 3-5 miles (8 km) thick under the oceans (oceanic crust) and about 25 miles (32 km) thick under the continents (continental crust).The crust is made up of mainly silicate rocks (about 85%).

An artist's impression of 2MASS J2126, which takens 900,000 years to orbit its star, 1 trillion kilometers away. Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system.

- June 10, 2013. he Hubble Space Telescope site estimates there are hundreds of billions of galaxies in the universe. A recent German super-computer simulation estimates that the number may be as high as 500 billion, with many older than the Milky Way.

Galaxies Nearly all stars belong to gigantic groups known as galaxies. The Sun is one of at least 100 billion stars in our galaxy, the Milky Way. And there are billions of galaxies in the Universe. Everywhere we look in the sky there are galaxies of different shapes and sizes. Some are spirals, with curved arms wrapped around a bright central core.

Quasars: Brightest Objects in the Universe Quasars live only in galaxies with supermassive black holes — black holes that contain billions of times the mass of the sun. Although light cannot escape from the black hole itself, some signals can break free around its edges.

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.

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).

Number of Stars in the Milky Way Stars are located in galaxies, but a galaxy contains more than just stars. Clouds of dust and gas, called nebulae, are where stars are born. In our galaxy alone, the Milky Way, there is a predicted 3 billion to 100 billion stars.

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...

How many galaxies are there in the universe? How do we know how many galaxies are in our universe? According to the best estimates of astronomers there are at least one hundred billion galaxies in the observable universe. They’ve counted the galaxies in a particular region, and multiplied this up to estimate the number for the whole universe.

Galaxy A galaxy is a large collection of stars, glowing nebulae (clouds), gas, and dust bound together by gravity. Many scientists now believe that a black hole, the remains of a massive star, lies at the center of many galaxies. Galaxies are as plentiful in the universe as grains of sand on a beach.
