It seems that astronomers aren’t even sure how many there are in the galaxy. Outside that, there are … Pages (550 words) Approximate price: $ 22.

The European Space Agency's Gaia mission is mapping the locations of approximately 1 billion stars in the Milky Way. However, various estimates are available: some based on the shape and size of our Galaxy, others based on our Galaxy’s likely mass. Even at that rate, it takes about 250 million years to travel once around the Milky Way… These estimates typically range from 100 billion to 400 billion stars. The light originates from the accumulation of unresolved stars and other material located in the direction of the galactic plane.

Astronomers estimate that the halo is just as massive as all of the stars in the Milky Way. Various estimates range from 100 billion to 400 billion, because some stars are not visible from Earth for multiple reasons: some of them being too far, too faint, or obscured by gas or dust..

"You have already liked this page, you can only like it once! This is called "A technique called "long-slit spectroscopy" is best for performing this type of work. Rudimentary math says that, if the Milky Way has 400 billion stars, each with 1.6 planets, there are roughly 640 billion planets. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone.

Kornreich often uses the 200-inch telescope at the Palomar Observatory at the California Institute of Technology, but he added that almost any telescope of sufficient size would be adequate.The ideal would be using a telescope in orbit because scattering occurs in Earth's atmosphere from light pollution and also from natural events — even something as simple as a sunset. This area is so thick with material that even powerful telescopes cannot see through it.

"It's a surprisingly difficult question to answer. The Sun belongs to a galaxy called the Milky Way. it's important to distinguish between the universe as a whole and the observable 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. You can't just sit around and count stars, generally, in a galaxy," said David Kornreich, an assistant professor at Ithaca College in New York.

ESA's infrared space observatory Herschel has made an important contribution by 'counting' galaxies in the infrared, and measuring their luminosity in this range – something never before attempted.Knowing how fast stars form can bring more certainty to calculations. When you multiply those numbers together, you get..... (what colin said)Let's just say there is a star for every dollar on Earth. We bring you the neatest, weirdest, and Further, the size of the stars itself can greatly vary from something that is the size of our sun, to something dozens of times smaller or bigger.The number of stars is approximately …So is there any way to figure out how many stars are for sure?
