there are 100 billion of galaxies in the universe , this number is likely to increase to about to about 250 billion as telescope technology in space improves .
Galaxies — those vast collections of stars that populate our universe — are all over the place. But how many galaxies are there in the universe? Counting them seems like an impossible task. Sheer numbers is one problem — once the count gets into the billions, it takes a while to do the addition. Another problem is the limitation of our instruments. To get the best view, a telescope needs to have a large aperture (the diameter of the main mirror or lens) and be located above the atmosphere to avoid distortion from Earth's air.
Perhaps the most resonant example of this fact is the Hubble eXtreme Deep Field (XDF), an image made by combining 10 years of photographs from the Hubble Space Telescope. The telescope watched a small patch of sky in repeat visits for a total of 50 days, according to NASA. If you held your thumb at arm's length to cover the moon, the XDF area would be about the size of the head of a pin. By collecting faint light over many hours of observation, the XDF revealed thousands of galaxies, both nearby and very distant, making it the deepest image of the universe ever taken at that time. So if that single small spot contains thousands, imagine how many more galaxies could be found in other spots.
While estimates among different experts vary, an acceptable range is between 100 billion and 200 billion galaxies, said Mario Livio, an astrophysicist at the Space Telescope Science Institute in Baltimore, Maryland. When the James Webb Space Telescope launches in 2020, the observatory is expected to reveal even more information about early galaxies in the universe. In 1995, astronomers pointed the telescope at what appeared to be an empty region of Ursa Major, and collected 10 days' worth of observations. The result was an estimated 3,000 faint galaxies in a single frame, going as dim as 30th magnitude. (For comparison, the North Star or Polaris is at about 2nd magnitude.) This image composite was called the Hubble Deep Field and was the farthest anyone had seen into the universe at the time. Measurements of the universe's expansion — through watching galaxies race away from us — show that it is about 13.82 billion years old. As the universe gets older and bigger, however, galaxies will recede farther and farther from Earth. This will make them more difficult to see in telescopes.
The universe is expanding faster than the speed of light (which does not violate Einstein's speed limit because the expansion is of the universe itself, rather than of objects traveling through the universe). Also, the universe is accelerating in its expansion.
This is where the concept of the "observable universe" — the universe that we can see — comes into play. In 1 trillion to 2 trillion years, Livio said, this means that there will be galaxies that are beyond what we can see from Earth.
"We can only see light from galaxies whose light had enough time to reach us," Livio said. "It doesn't mean that that's all there is in the universe. Hence, the definition of the observable universe."
meanwhile many years ago during the human/celestials race ., the galaxy URANUS was obliterated by the SHIELD OF LIGHTS a half human bennet bright she is called PHOEBUS often called SUN which was once the eye of a wicked god CRONUS (the angel of death) , he was defeated by the bright .PHOEBUS paid a price with her life to stop the death of humans and celestials (DARKNESS) .. she bacame the first creation to orbit APOLLO .. between these period of time in about 100 million years the offsprings of the ancient creatures ( humans,chimeras ,were jaguars ,hellhounds , werewolfs , celestial ) . orbited the galaxy MIRANDA . this galaxy is being ruled by PELOPS grandson of ZEUS .containing 400 billion creatures in this planet, during these period death no longer exists after PHOEBUS took darkness to her tomb … in the whole UNIVERSE darkness never surfaced anymore .NYMPHS were the creatures orbiting MIRANDA is a minor female nature deity. Different from Greek goddesses, nymphs are generally regarded as personifications of nature, are typically tied to a specific place or landform, and are usually depicted as beautiful maidens. They were not necessarily immortal, but lived much longer than humans before they died. They are often divided into various broad subgroups, such as the Meliae (ash tree nymphs), the Naiads (freshwater nymphs), the Nereids (sea nymphs), and the Oreads (mountain nymphs).
Nymphs often feature in many classic works of art, literature, mythology, and fiction. Since medieval times, nymphs are sometimes popularly associated or even confused with fairies. The Greek word νύμφη has the primary meaning of "young woman; bride, young wife" but is not usually associated with deities in particular. Yet the etymology of the noun νύμφη remains uncertain. The Doric and Aeolic (Homeric) form is νύμφα.
Modern usage more often applies to young women at the peak of their attractiveness, contrasting with parthenos (παρθένος) "a virgin (of any age)", and generically as kore (κόρη < κόρϝα) "maiden, girl". The term is sometimes used by women to address each other and remains the regular Modern Greek term for "bride". Nymphs were sometimes beloved by many and dwelt in specific areas related to the natural environment, e.g. mountainous regions, forests, springs. Other nymphs were part of the retinue of a god, such as Dionysus, Hermes, or Pan, or a goddess, generally the huntress Artemis.
The Greek nymphs were also spirits invariably bound to places, not unlike the Latin genius loci, and sometimes this produced complicated myths like the cult of Arethusa to Sicily. In some of the works of the Greek-educated Latin poets, the nymphs gradually absorbed into their ranks the indigenous Italian divinities of springs and streams (Juturna, Egeria, Carmentis, Fontus) while the Lymphae (originally Lumpae), Italian water goddesses, owing to the accidental similarity of their names, could be identified with the Greek Nymphae. The classical mythologies of the Roman poets were unlikely to have affected the rites and cults of individual nymphs venerated by country people in the springs and clefts of Latium. Among the Roman literate class, their sphere of influence was restricted and they appear almost exclusively as divinities of the watery element.
