Will the PGC catalog have at least all 100 billion galaxies in the observable universe?

No, because it will be impossible for the PGC catalog to have at least all 100 billion galaxies in the observable universe.

Can astronomers make an astronomical catalog that lists B1950 and J2000 equatorial coordinates and cross-identifications for all 100 billion galaxies in the observable universe?
No, because it will be impossible for astronomers to make an astronomical catalog that lists B1950 and J2000 equatorial coordinates and cross-identifications for all 100 billion galaxies in the observable universe.
Is it impossible to do all the redshifts of the 100 billion galaxies in the observable universe?
Yes. To image, catalog, and calculate the redshift of each galaxy individually would take an extremely long time. In order to complete the work in 100 years we would need to measure redshifts at a rate of more than 30 galaxies per second.
Is it impossible to list all the designations distances shapes and sizes of all 100 billion galaxies in the observable universe?
Actually, it is possible, however such catalog would require considerable resources and time to be completed. In fact, we have only detected 100 billion because our sensing capabilities improved since the launch of the Hubble space observatory. If we could improve our capabilities in the coming years for just a slight amount, we could detect another 100 billion.Just for you to ponder: a team of astronomers from the Pennsylvania State University have recently completed a survey, known as the Glimpsing Heat from Alien Technologies Survey(or G-HAT), of 100,000 galaxies to see if they could find traces of galaxy-spanning super-civilizations. It took over a year to be completed.Extrapolating these results, it would take more than 1 million years to have the full catalog of galaxies in the observable universe, using the present technology.
What is an astronomical catalog?
An astronomical catalog is a catalog of astronomical objects in the viewable universe, whether by the naked eye or through telescope or other means, used to explore the universe in hopes to discover new astronomical objects.
Who found about the galaxies?
Galaxies are visible to the naked eye, so early observers no doubt saw them. But without telescopes, even the sharpest vision only showed them a small smudges in the sky. In the late 1700s, the French astronomer Charles Messier couldn't have cared less about other galaxies, and in fact, didn't know what they were. Messier was a comet hunter, and finding comets was his great joy in life. To speed his discovery of potential comets, Messier created a catalog of smudgy comet-like things in the sky that were NOT comets, so that he could quickly reject them the next time he saw them. These Messier Catalog objects were, predominantly, other galaxies, and many of the galaxies that we still study are named or referenced by their numbers in Messier's catalog. For example, the Great Nebula in Andromeda, sometimes called the "Andromeda galaxy", is item number 31 on Messier's list; M31 in Andromeda.
What is the name of the known galaxy that is farthest away from the Milky Way?
as far as I know there is no farthest galaxy from earth. However There is (Of course) a farthest Visible galaxy. However I do not know the name of this galaxy. (I hope someone comes along and improves my answer to this question.)
Are quasars and active galaxies cosmic cannibals?
well actually all galaxies are active, and yes they do combine after a dance across the sky, and the center of the galaxies combine, I wouldn't call it eating though because all they do is combine with each other. ______________________________________________________________________ The Andromeda galaxy is approaching our Galaxy at about 300 Km/s, and the collision between both galaxies will take place in about 4.5 billion years. Andromeda galaxy is larger in both astronomical size and number of stars than the Milky Way, although Andromeda may not be the most massive, as recent findings suggest that the Milky Way may contain more Dark Matter, and so could be most massive than Andromeda (galaxy Messier 31 or National General Catalog 224). Who will «eat» who? Bets are accepted...
What is the name of the furthest glaxay from earth?
Galaxies so far away that they cannot be seen don't have names, just catalog numbers. However the furthest galaxy from earth is abell 1835 ir1916. it is also the largest galaxie.
How much is the Beatles publishing catalog worth?
Around 2005 - $400 million Around 2007 - $500 million Right now, $1-2 billion. It is believed.
What is a catalog of languages called?
A catalog of languages is typically called a language catalog or a linguistic catalog.
Can you give a sentence with the word catalog?
The catalog was sent by mail. The library did not have it in their catalog. You can catalog the animals by their species.
Is the moon similar to other moons in the universe?
Our moon, Luna, is indeed similar to many other moons even in our own solar system, much less the universe as a whole (which has not really be examined in sufficient detail to enable us to catalog moons in other stellar systems).
