The number of stars you would need to search before expecting to hear a signal depends on several factors, including the density of stars in the region, the likelihood of intelligent civilizations existing, and the duration and strength of their signals. Estimates from projects like the Drake Equation suggest that, within our galaxy, you might expect to find a signal after searching thousands to millions of stars, depending on the assumptions made about the parameters involved. Thus, it is a complex calculation, but many scientists believe that even with extensive searching, contact may still be rare.

What planets have morning and evening stars?
Earth and Venus. From Earth Venus and Mercury are planets visible as "morning" and "evening" stars. From Venus, Mercury would appear in the morning and evening sky. From Mars I would expect Earth, Venus, and Mercury to all be morning and evening "stars."
Why might stars of one color be much more abundant than stars of another color?
Red Dwarf stars are the commonest in the Galaxy. Red Dwarf stars last much longer than blue stars for example. So you would expect to find more of these red stars. You need a telescope to see them, but they are very common.
What came first the sun or the stars?
Stars came first before the sun. Stars formed billions of years before the sun did as part of the process of galaxy formation. The sun is a relatively young star compared to many others in the universe.
Are there other planets Andromeda galaxy?
We expect the Andromeda galaxy to be just like our own Milky Way galaxy. We can see stars (suns) in the Andromeda Galaxy and just as stars have planets orbiting them in our galaxy, we believe that there must be planets also orbiting stars in the Andromeda galaxy.
In what part of the Milky Way would you expect to find most of the population 2 stars?
Most Population II stars are found in the halo of the Milky Way galaxy, particularly in globular clusters and the surrounding stellar halo. These stars are typically older, metal-poor, and represent an early stage of star formation in the galaxy. While they can also be found in the bulge, the halo is their primary region, as it contains the remnants of ancient stellar populations formed before the galaxy's disc structure developed.
Why hotels are rated by stars?
Hotels are rated by stars so you know what to expect from that hotel when you book it.
What is the duration of Before They Were Stars?
The duration of Before They Were Stars is 1800.0 seconds.
When was Before They Were Stars created?
Before They Were Stars was created on 1996-02-01.
When did Before They Were Stars end?
Before They Were Stars ended on 1996-06-01.

Who stars in the film The Signal?
The stars in the film, "The Signal", are Anessa Ramsey, Sahr Ngaujah, AJ Bowen, Matthew Stanton, and Suehyla El-Attar. The characters they play are Mya Denton, Rod, Lewis Denton, Jerry, and Janice.
Why is it impossible to see stars during the day?
You can see the Sun - and that is a star. The light from the sun swamps out the light from the stars, (signal to noise ratio).
If there are 120 civilizations broadcasting radio signals in the Milky Way on average how many stars would we have to search before expecing to hear a signal assuming 500 billion stars in the galaxy?
The simple answer would be to divide 500 billion by 120, which gives an answer of slightly over four billion. The reality might be different, however. Just because a civilization is broadcasting radio signals does not mean that we necessarily can detect those signals. The Milky Way galaxy is 200,000 light years across on its long axis (80,000 on its shorter axis) and there are some stars which are so far away that it would take tens of thousands, even a hundred thousand years for a radio message to reach the Earth, and the hypothetical broadcasting civilization might not have been broadcasting for that long. And even if they were broadcasting long enough, the signal strength might not be enough to allow us to separate it from the background noise. And we might not be listening on the same frequency on which they are broadcasting. Those are just the most immediate complications.
Why is the search of planet around other stars important?
The thing is some people want a planet to be named before then so they search while the majority of the astronomers want to find a earth like planet so we can occupy them and continue our lives, some do it map the universe
What do the stars mean that are next to a site when you search on Google mean?
Google has abandoned SearchWiki. Google has replaced it with stars in Google search. Think of stars like bookmarks on steroids. What happens when you star a search result or map item? First that item will sync with Google Bookmarks and Google Toolbar. Second, the next time you perform a search, when relevant, that item will appear in a special list right at the top of your results.
Why when you look into the night sky is it in the past?
Because light from the stars travelled quite a while before it reached the Earth.Because light from the stars travelled quite a while before it reached the Earth.Because light from the stars travelled quite a while before it reached the Earth.Because light from the stars travelled quite a while before it reached the Earth.
