How many number of stars?
Just in our galaxy - the Milky Way - there are several hundred billion stars. In the visible Universe, there are hundreds of billions of galaxies. It is not currently known how far the Universe extends, beyond the visible limits. A rough estimate, then, would be that there are 1011 x 1011 = 1022 stars (a one with 22 zeroes, that is), just in the visible Universe - the part that our instruments can reach in theory.
Are there 27 stars in the universe?
There are billions of stars in the universe, far more than just 27. Stars are spread across galaxies, and each galaxy can contain billions or even trillions of stars. The universe is vast and expansive, with countless stars yet to be discovered.
Why is a black hole considered an oddity in the universe?
Considering the other oddity's in the Universe; Neutron stars, pulsars, Wolf Rayet stars, magnetar or even hypernovas, I don't think black holes are that odd.
What percent is main sequence stars?
Main sequence stars make up about 90% of all stars in the universe. They are the most common type of star and are considered to be in a stable phase of their lifecycle.
Why does the universe not contain any black dwarf stars?
It is not old enough. It is estimated that it would take trillions of years for a white dwarf to a black dwarf. The universe is only about 13.8 billion years old.
How meany galaxies and stars are there in this universe?
In the VISIBLE UNIVERSE, there are somewhere in the order of 1011 galaxies; each galaxy on average has 1011 stars, for a total of (very roughly) 1022 stars.

What is the number of stars vin the universe?
Currently there are estimated 400 billion stars according to astronomers, althrugh not all are visible in the night sky.
What is the major force in universe?
Gravity is considered to be the major force in the universe, governing the motion of planets, stars, and galaxies.
How does the size of the sun compare to that of other stars in the universe?
The size of the sun is considered average compared to other stars in the universe. There are much larger stars, known as supergiants, and much smaller stars, known as dwarfs. The sun falls in the middle range in terms of size among the billions of stars in the universe.
Do sun contain most of the visible material?
No. The sun is a fairly average sized star out of billions of stars.
Why do scientists believe that stars contain the same elements as the solar system?
Scientists believe that stars contain the same elements as the solar system because all elements in the universe are created through nuclear fusion in the cores of stars. Elements are dispersed into space when stars explode as supernovae. These elements then form new stars, planets, and other celestial bodies, resulting in the similarities in elemental composition between stars and our solar system.
Why does the universe contain less hydrogen then it used to?
Some of the hydrogen has been converted into heavier elements by stars.
What are all the galaxies?
The collection of all visible or detectable galaxies is known as the universe. Each galaxy is a vast collection of stars--billions of them. Some galaxies have trillions of stars.
How many star make up our universe?
The amount of stars in the Universe is not know. The visible Universe has several hundred billion galaxies, each of which, on average, has perhaps a hundred billion stars or more. Even the exact shape of the Universe is an area of current research. In any case, it does seem that the Universe is much bigger than it was believed a few decades ago.
Why is a black hole considered an oddity in the universe?
Considering the other oddity's in the Universe; Neutron stars, pulsars, Wolf Rayet stars, magnetar or even hypernovas, I don't think black holes are that odd.
