Are all shiny things contained by the sky stars?
Are all of these other suns from other solar systems within our same galaxy (Milky Way)?
How many other galaxies are in attendance? how do we know?
Answers:
YES
YES
BILLIONS - cannot be counted
We know because they hold tried to count them and can't
All the shiny things in the hours of darkness sky are stars, comets, or meteriods but mostly stars and there adjectives from the milky way galaxy. The rest of the stars within other galaxies are not visible to the unclothed eye. There are many of other galaxies out near. Lets put it this way, if you counted respectively grain of sand within the world thats how many galaxies within is in the universe.
There has to be another Solar System somewhere, but not respectively star has one. The star have to be the same size and warmness with upright enough planets to own a proper Solar System.
As other posters have pointed out, several of the brightest objects contained by our sky are actually other planets surrounded by the solar system. You can also occasionally see (man-made) satellites passing overhead.
But yes, most of the stars we can see are in reality suns in other solar systems. Most of them are from our own galaxy, although some of the things that look close to stars are actually full galaxies with millions of their own suns (you can't see individual stars surrounded by other galaxies without a massive telescope though).
Current thinking say that the universe is finite, so the number of other galaxies is not infinite - although it is very colossal and may be hundreds of billions.
And yes, my own suspicion is that there probably are other life-forms out in that. Whether we'll ever be able to communicate beside them is a different question.
SUN, MOON AND TEN OTHER LOCAL OBJECTS ARE ONE SET OF EXCEPTIONS
There are six planets in our own solar system that are noticeable to the naked eye lower than good sky conditions (no city lights, no clouds or moon) (though not adjectives the time): the five known from antiquity (Mercury, Venus, Mars, Jupiter, Saturn) and Uranus. In adjunct the four brightest (largest) moons of Jupiter (Io, Callisto, Ganymede and Europa) are 5th magnitude at their brightest.
"SOLAR SYSTEM" IMPLIES THERE ARE PLANETS AROUND A STAR
Whilst most of the other points of wishy-washy are stars and those stars are all member of our own galaxy THAT DOESNT MEAN THEY ALL HAVE PLANETS AROUND THEM, So far we know of only 210 extra-solar planets (all surrounded by our galaxy) and there are some 200 billion stars surrounded by our galaxy,
There are some exceptions to the statements "they are all stars" and "they are adjectives in our galaxy" to information however:
M31 The Andromeda Galaxy 2.5 million light years away, is the nearest disqualified spiral galaxy to our own, Magnitude 4.36.
M33 The Triangulum Galaxy 2.6 million light years away, is the second nearest spiral galaxy to our own, Magnitude 6.3.
Large Magellanic Cloud: size 0.9 at a distance of about160,000 light-years.
Small Magellanic Cloud: magnitude 2.7 at a distance of just about 200,000 light-years,
Until the discovery of the Sagittarius Dwarf Elliptical Galaxy in 1994, they be the closest known (dwarf) galaxies to our own.
However these four objects, though not section of our galaxy, are all member of the Local Group of Galaxies. so it may be the case that everything noticeable in the sky is subdivision of the Local Group,
THE NUMBER OF STARS IN THE UNIVERSE
70 Septilion (7 x 10^22) is the current best guestimate, arrived at by astronomers at the Australian National University
They did this by studying star densities in example spaces and then working out how masses such spaces there are contained by the observable universe.
Here is an edited version of one article reporting this:
"70 sextillion stars surrounded by the 'known' universe!
According to a study by Australian astronomers there are 70 sextillion (70,000,000,000,000,000,000,000 stars surrounded by the known universe.
It's also roughly 10 times as many stars as grain of sand on all the world's beach and deserts.
The figure be calculated by a team of stargazers base at the Australian National University.
Speaking at the General Assembly of the International Astronomical Union meeting contained by Sydney, Dr Simon Driver said the number was drawn up base on a survey of one strip of sky, rather than trying to count every individual star.
The squad used two of the world's most powerful telescopes, one at the Anglo-Australian Observatory in northern New South Wales state and one within the Canary Islands, to carry out their survey.
Within the strip of sky some 10,000 galaxies be pinpointed and detailed measurements of their brightness taken to calculate how plentiful stars they contained.
That number was consequently multiplied by the number of similar sized strips needed to cover the entire sky, Driver said, and then multiplied again out to the brim of the visible universe.
He said at hand were promising many million more stars contained by the universe but the 70 sextillion figure be the number visible inside range of modern telescopes."

Not necessarily
yes, yes and infinity
TO ALL RESPONDENTS. The milky instrument is the band of stars which are the stars within our galaxy seen boundary on. Think of our galaxy as a dinner plate and we, and our solar system, that is the sun and 9? planets orbit it, are somewhere about 3/4 the mode across and the edge man the milky way. What we see any side of that band is contained by general, low space This is very simplistic but should hand over you the idea. Have a look at the relation below.
Most of them are but like 2 conceivably less are planets contained by our solar system, eg mars. Yes adjectives the stars you see are in the milkyway galaxy
THere are billions of them possibly even a googol. We cannot possibly know cause we cant see them
Apart from the Moon, other planets contained by our Solar system that are visible at times and the the peculiar asteroid and comet or two, yes. As far as we know, there are countless galaxies surrounded by the Universe. As for life forms on distant planets, I would read aloud that it's a 100% certainty and that we would be fools to ruminate otherwise.
a large majority of the shiny things surrounded by the sky are in certainty stars however a small minority are planets the reason planets shine is due to the insubstantial reflecting from the sun. the sun is in reality the only sun because specifically the name of our star. nearby are to many stars to autograph and that is why everybody make the same assumption of every star man known as the sun
