The Boston and moon light

You will have been heard the name of moon light. And we will learn how the great difference between the moon light and the Boston light. The moon is known everyone and the moon light is also known. When we are a baby Mother was seen us the moon and from then we are familiar from the moon and its light. The super moon is seen for a regular time interval and when we can see the super moon it light us with the highest flux because in this time the moon is get the full circle shape. As a result, during this time the moon emit maximum flux of light. Boston light is one of the oldest light stations in America. It is situated in Little Brewster Island in Boston Harbor. It is one of the best creations in the world and was made by America’s scientists. They make it with the compare of the moon and in the Boston Harbor, Massachusetts it is also recognized the most historical light station. The Boston light structure is very consecutive and is one of the most famous creations in the world. The Boston lighthouse is covered an area of undetermined acres. In the time of the established it was cost a huge amount of money and took a long time and also there were at least thousand people worked very hard. It is situated in the sea shore of the city of Boston Harbor, Massachusetts. The environment around the greatest light is basically neat and clean. Therefore, public in each country visited this place every year. It has renowned publicity all over the world. As it is a public place so there are many hotels and restaurants beside the light station. It is also situated by the side of a hill Nantucket.  The lighthouse was sacrificed it’s a portion to the company cannon. The light beam of the light house is only seen when it is night. At the evening, beside the lighthouse people gathered here and there for getting treat about them. As it is compared with the full moon light so its work is looking like the moon. In the time of monsoon when the environment is gray and foggy its look very nice and it is seen approximately vanished cream. When it is time for established and celebrate the day of anniversary it was first announced by the government of America. The guests from home and abroad were getting engaged witnessed the first flashes of the light as it commenced its third century at sunset of the anniversary day. In the time of celebration of the day it was first seen as a great creation in the science and technology ever. The light is very powerful and it can emit light with high frequency. The lighthouse station is currently provided with a 1,800,000 candlepower light refracted through 1859 second order to reach in a particular place. It is visible around 27 miles distant apart to the inhabitants’ of the Harbor. This well-planned photo is taken by the organization of NASA. And it was captured on July 13, 2017 from the University of Harvard. The full Moon rise over the outside of the city of Boston Harbor, Massachusetts, planet Earth. In the foreground part that is the area of most importance and activity, or which people pay attention to historically, the historic extraterrestrial beam (a light or fire on the top of a hill that acts as a warning or signal) is known as Boston Light. So in this year of month July’s the moon in the sky is basically known to people now a days as a thunder Moon, might be a mention of something to noise sounds of the northern summer with strong wind, heavy rain and often thunder and lightning stormy weather. As you can see the eastern sky was clear for this image. Near the where the sky seems to touch the land or sea, the long sight-line through atmospheric layers which is filtrated and is being refracted on the moonlight, causing the rising Moon's great red color, no smooth edges and in original shape. The sizes of the moon and Boston lights are fully same but difference in quality because the one moon is created by the "ALLAH" and the other is created by men. So it is going to be cleared to the people all over the world that the Boston light is an artificial source of beam.

The Spiral Sunflower Galaxy (Messier 63 - M63)

Sunflower Galaxy (Messier 63 - M63)

The sunflower galaxy Messier M63 is one of the most beautiful and spectacular spiral galaxies in the history of the astronomy ever. The sunflower galaxy was discovered Pierre Mechain, the great friend of Charles Messier and the colleague he kept on 14 June 1779. They were made a important catalogue for making a history or a simple rough about their invention. As they made it their personal note so this note has a great importance in the history of their whole life. The French astronomer Charles Messier was a famous astronomer by making his personal catalogue which was helped in the next generation of the astronomical science. Because everyone needs the guide and proper direction about how can the play an important invention. In actual practice, the next apprentice in this stage will get the good views and can feedback the scientist.

This was a wonder invention in the history of the astronomical science. Because this discovery was the first deep sky object. Messier 63 is one of the greatest member of the group M51, this is also gravitationally bound by the galaxy located in Canes Venatici. 

A type of supernova was detected this item M63 galaxy on May 26, 1971. M63 is only one which is marginally fainter (not clear or strong, seemly at the slightly less clear) with the compare of the other member in this group.  It has a mass of 140 billion with the product of mass of the Sun. Think about it, how much greater the galaxy is! And it is not far behind its famous neighbor. Actually M51 and M63 groups are gravitationally bound by at least six other small galaxies in the universe. The galaxy M63 is best seen in the months of March, April or May at the northern Hemisphere of the earth. As it is look like as spiral so its beauty is always conversable of all time. In the universe the galaxy has a great importance to organize the galaxy or milkiway. The (η UMa – mag… +1.9) is the basic element of the galaxy and for this property of the galaxy is made over by this valuable element. NASA/ Hubble Space Telescope was first captured this photo, the arrangement of the spiral galaxy M63 is eventually at the centre of a sunflower. So this is the nickname of the cosmic object and it is also the member of cosmic objects ray. Canes Venatici is an unclear constellation (any of the groups of stars in the sky which seem from Earth to form a pattern and have been given names). We can see famous Plough asterism of Urfa Major starting origin which is originated from the source of the Usra Major point. There also a line is found is called Alkaid. What is Alkaid? So this is an imaginary line passing through southwesterly direction making a small angle in magnitude 14 degrees. The greatest starts Cor Canoli(α CVn - mag.. +2.9), Canes Venatici and others are get focused at the end of this imaginary line. The galaxy M63 take a suitable position about the 2/3 radians of this total degrees.

Messier 63 are also known as NGC 5055 the member of group M51. It is surrounded by many small spiral arms of the spiral galaxies segments. Most of the galaxies are active and the best example is M63 a group member of M51. There are also a number of inactive spiral galaxies which is not performed like others. The neutrals are always out of control because it was carefully observed and it won’t be able to create a mind-blowing situation on human nature. 

What is Star Cluster Omega Centauri in HDR

The history of the Star Cluster Centauri

What is Star Cluster Omega Centauri in HDR

The history of the astronomical physics has a revolutionary and effective wonder in the Cluster Omega. As it is the total package of the stars and it contain the unlimited stars, whatever you imagine about this sustainable Centauri. The Hubble Telescope have found the fact about it and declared that it is act like a giant star Cluster. As the package is being created by this series so the volume of the Centauri is unknown yet because of the greatness of the Centauri of the Star Cluster. This image contains a massive globular star cluster with a big area in the Milky Way Galaxy. So all of the globular star clusters are very impressive (If an object or achievement is impressive, you admire or respect it, usually because it is special, important or very large) for people, on the other hand the star cluster are unimpressive (Not great to respect as well). The Omega Centauri has a mass of 5 times to the mass of the sun. So think about this greatness about that. It has a diameter about 230 light-years. And the light is allowed to pass after 10 million years and the speed of light in the vacuum is 3*10⁸ ms^-1. It seems to be look like an open star but it is really a globular system in shape and all of the stars are in the center of this cluster. As an open star is a system of millions of young stars so it is a great value and placed in the vacuum in the Milky Way. The Omega Centauri emits the ray of infrared. It is harmful for people in the open eye. Generally it is visible and it may take 12 thousand light-years distance to reach on the earth and as the distance is very high so the infrared ray cannot able to harm for human skin and eye. In the school of astrophysics the Omega Centauri is a giant star Cluster in the history of Astronomy. Please look at the greatest ball of stars in our galaxy. Omega Centauri is completely full with about 10 million stars, many older than our Sun and packed within a volume of only about 150 light-years in diameter. The star cluster is the largest and brightest of 200 or so known globular (especially a drop of liquid) clusters that roam the haloes of our Milky Way galaxy. In spite most star clusters persist of stars with the same age and composition, the enigmatic Omega Centauri exhibits the presence of different stellar populations with a expand of ages and chemical abundances. Truly, Omega Centauri is a package of at least 10 million stars approximately. Truly it may be the remnant (a small piece or amount of something that is left from a larger original piece) core of a small galaxy merging with the Milky Way. The featured image shows so many stars as the Centauri is a package about 12 million stars contained within a helical shaped container. The chemical structure of the Centauri is very simple and it is simply made by some particles. There are about 12-15 layers in the structure of the Star Cluster. There are many elements in the structure of the Cluster. In each layers chemicals may be same but in actual practice the density of the chemical or molecular element are different. So this is the simple but heavy informative article about the life of the Star Cluster Centauri.

Spiral Galaxy NGC 1512 hide in the plain sight

Beautiful starlit galaxies with majestic spiral arms just like our own Milky Way--consist of flat, rotating disks composed of billions of sparkling, fiery stars, dust, and gas, with a central concentration of stars termed a bulge. These spirals are also encircled by a faint halo of stars, many of which inhabit globular clusters. Spiral galaxies got their name because of their spiral arms that make them look like enormous sparkling star-blasted pin-wheels whirling around in space--and the lovely spiral arms extend from the center of the galaxy into the disk. In March 2016, astronomers announced that they have made the surprising discovery of a strange, new, and distant kind of galactic pin-wheel in the sky, whirling majestically in the dark wilderness of intergalactic space. These newly discovered galactic behemoths have been named super spirals, and they dwarf our own large spiral Milky Way--competing in brightness and size with the largest galactic denizens of the Universe. Super spirals have hidden in plain sight for a very long time. They hide by mimicking the appearance of the more typical batch of ordinary spirals.

The new study, using archived NASA data, demonstrates that these seemingly nearby structures are in fact distant, and giant versions of typical spiral galaxies, like our own. These rare super spiral galaxies sing a siren's song to curious researchers who try to find a solution to the intriguing mystery of how such behemoths could have arisen. The billions of starlit galaxies that inhabit our Universe today were born a very long time ago, and their stellar inhabitants lit up what was previously an ancient swath of featureless darkness. This brilliant cosmological fireworks display occurred less than a billion years after the Big Bang birth of the Universe almost 14 billion years ago. The prevailing, and most recent, explanation for the emergence of galaxies so very long ago--playfully referred to as the "bottom-up" theory--indicates that large galaxies were uncommon inhabitants of the ancient Universe, and that they finally attained their large and majestic sizes as a result of mergers occurring between considerably smaller, shapeless protogalactic blobs. Disk galaxies, such as our Milky Way, are famous for their starlit arms. However, there is another class of galaxies that display less well-defined structures, termed lenticular galaxies. Lenticulars, like their spiral cousins, sport flattened, circular regions composed of gas and dust. Indeed, lenticulars are defined by their display of pancake-shaped regions of dust and gas that distinguish them from their elliptical galactic relatives. In contrast to their spiral kin that display structure and organization, ellipticals are more three-dimensional, and show very little in the way of structure. The sparkling stellar constituents of ellipticals travel in, more or less, random orbits around the center of their host galaxies. Lenticular galaxies are considered to be intermediate structures between spirals and ellipticals. This is the reason why ellipticals are frequently referred to as "armless spiral galaxies," because they display a bulge, but no indication of pin-wheel-like spiral arms. According to the bottom-up theory of galactic birth, large galaxies ultimately attained their enormous and majestic sizes as a result of mergers between smaller proto-galaxies zipping around in the ancient Universe. The earliest galaxies furiously gave birth to brilliant and sparkling neonatal proto-stars. Primordial star-burst galaxies were only about one-tenth the size of our Milky Way, but they were just as fabulously fiery with blasts of starlight because of these amazingly furious episodes of starry fireworks. Galaxies were born in the featureless, dark swath that was the primordial Universe when opaque clouds of primarily hydrogen gas gathered together along massive filaments of invisible dark matter. Even though scientists have not as yet determined the identity of the particles that compose the dark matter, it is generally thought that it is not composed of so-called "ordinary" atomic matter, termed baryonic matter. The very badly misnamed "ordinary" atomic matter is the truly extraordinary material that composes stars, planets, moons, and people literally all of the atomic elements listed in the familiar Periodic Table. The very extraordinary "ordinary" atomic matter composes a mere 4.6% of the Universe, while dark matter accounts for a considerably more abundant 24% of it. The lion's share of the Universe 71.4% of it is made up of the truly weird and mysterious dark energy. Dark energy is a bizarre substance, thought by many scientists to be a property of space itself--and it is causing the Universe to speed up in its relentless expansion. In the very ancient Universe, especially dense regions of dark matter exerted an irresistible gravitational pull on wandering, floating clouds of pristine gas. Dark matter does not interact with atomic matter or electromagnetic radiation except through the force of gravity. However, because it does interact with "ordinary" atomic matter, and it warps and bends the path light takes (gravitational Lansing), it shows its ghostly presence in the Cosmos despite its haunting invisibility. Gravitational lending was first proposed by Albert Einstein when he came to the realization that gravity had the ability to warp and bend traveling light and therefore exert lens-like effects. Ghostly and strange, the invisible dark matter trapped clouds of pristine gas. Thus, these clouds of ancient gases became the strange cradles of the first generation of brilliant newborn stars that lit up the previously dark and featureless Universe. The massive filaments of dark matter that spun a mysterious Cosmic Web throughout Space and Time, snatched up its baryonic prey until the trapped clouds of gas formed blobs that sunk down, down, down like black sequins into the centers of these phantom-like, ghostly, and invisible halos of dark matter. Slowly, relentlessly, the swirling sea of primordial gases and the haunting, eerie, phantom-like dark matter, floated throughout the primordial Universe, combining together to ultimately create the distinct and familiar structures that we observe today. Areas of greater density within the filaments of dark matter, weaving the mysterious Cosmic Web, flowed through the entire early Universe and became the precious seeds from which the galaxies emerged. The gravitational lure of those primordial seeds slowly embraced the ancient gases, which then formed ever tighter and tighter clouds. Most astronomers think that these clouds of gas began to gather together in clusters, and that these proto-galaxies, both large and small, performed a strange dance together that created increasingly larger and larger galactic structures. The proto-galaxies danced around together as the result of gravity, forming increasingly vast structures destined to become the enormous, majestic galaxies of our Cosmos. Like bits of dough in the hands of a pastry chef, the proto-galaxies smacked into each other to form ever-larger masses. The early Universe was much smaller then it is now and extremely crowded. Therefore, the proto-galaxies frequently bumped into one another and stuck together.

Explanation about how to see the earth night from others planet: 

Can you find your favorite country or city? Surprisingly, on this world-wide night escape, city lights make this task quite possible. Human-made lights to attract attention to or emphasize something important particularly developed or populated  areas of the Earth's surface, including the seaboards of Europe, the eastern United States, and Japan. Many  large cities are located near rivers or oceans so that they can exchange products cheaply by boat. Especially  dark areas include the central parts of South America, Africa, Asia, and Australia. The featured composite(specialized a structural material made up of more than one substance) was created from images that were collected during cloud-free periods in April and October 2012 by the Suomi-NPP satellite, from a polar orbit about 824 kilometers above the surface, using its Visible Infrared Imaging Radiometer Suite (VIIRS).

Explanation about this: 

A Similar in size to large and the bright spiral galaxies in our neighborhood, IC 342 is a distant of 10 million light-years in the long-necked, northern constellation Camel-opardalis.  A sprawling (i.e.  a large area of land covered with buildings which have been added at different times so that it looks untidy) island universe, IC 342 would otherwise be a Famous galaxy in our night sky, but  it is hidden from clear view and only glimpsed (a quick idea or understanding of what something is like this biography offers a few glimpses  of  his life before he became famous) through the veil of stars, gas and dust clouds along the plane of our own Milky Way galaxy. Even though IC 342's light is dimmed by intervening (happening between two times or between other events or activities) cosmic clouds, this sharp telescopic image traces the galaxy's own obscuring (Two new skyscrapers had sprung up, obscuring the view from her window) dust, blue star clusters, and glowing pink star forming regions along spiral arms that wind far from the galaxy's core. IC 342 may  have undergone a recent burst of star formation activity and is close enough to have gravitationally influenced  the evolution of the local group of galaxies and the Milky Way.

Atlas, Daphnis, and Pan are small and inner, ring moons of Saturn, shown at the same scale in this montage of images from the still Saturn-orbiting Cassini spacecraft. In fact, Daphnis was invented inCassini images from 2005. Atlas and Pan were first sighted in images from the Voyager 1 and 2 spacecraft. Flying saucer-shaped Atlas orbits near the outer edge of Saturn's bright A Ring while Daphnis orbits inside the A Ring's narrow Keller Gap and Pan within the A Ring's larger Encke Gap. The curious equatorial ridges of the small ring moons could be built up by the accumulation of ring material over time. Even diminutive Daphnis makes waves in the ring material as it glides along the edge of the Keller Gap.

Water jet cutting Machine using to cut anything

 

 Introduction

Scientists and the engineer are always tried to make alternate way how to increase the benefit of technology. As a result there is a huge competition in technology. Which companies make their product well and which companies make their product very usable and synthetic it is now a mind blowing question today. 

The other fact is that who make the new technology, so it is very important for a well development product. So today we will see the newest but oldest technology about how to cut any metal by water. Also we will learn how we can use high pressure energy to produce any work energy. In ancient time there were no alternative ways to break and cut any metal like this technology. The mind blowing inventions in the science and technology make the human life easier and comfortable. It is really true for giving someone assurance that water can cut any kind of metal where it is very hard or very wide/depth. So it is possible only when one can get proper idea from the machine. We will learn about the machine which is called jet cutting machine. It must be discovered in recent years and it is get popularity in many countries companies. In the great construction building there is impossible to use the heavy weight machine to cut any portion of metal and anything. So this machine can solve this problem and it easy to carry anywhere. On the other hand it is only a few weights which are light to carry. It is discovered by a group of young scientists. It is really a wonderful invention in human kind.
How it works

For cutting anything you have to make sure that your instrument is setup properly. Then set the equipment into the bottom of the jet cutting machine. Water may be pure and it should be put in the jar in the machine. When your setup will be ready then start the machine and see what happen in this time. You will be really astonished after seeing this. When you will cut something the water possesses the potential energy and when the water will push then we must have to remain that the pressure is very high. The water will be pushed at high speed, over 50,000 psi. If you want to make it better then you have to modify the machine. So this is the process how one can cut any kind of metal by only water.

The energy in the machine is  required for cutting any kind of  materials is obtained by pressurizing water to ultra-high pressures and forming an extreme cutting stream by focusing this high-speed water through a small, expensive-stone orifice ( an opening or hole of anything is just one). There are mainly two steps by cutting the Jet cutting machine


1. The (E.S.P.) Electric Servo Pump is used for generally to pressurize the normal water at high pressure levels, which may be at extreme value of 50,000 psi. The maximum high speed pressure will help to produce required the energy for cutting the required metal. Then the streamline is focused to cut the metal at high-speed through a small tube of orifice which is extremely without radius. Actually if you calculate the speed of sound it will be the three times of the sound of speed. It is depending on how much force is needed to cut it and how much force we have to exert on it.


2. The machine requires very high energy and as a result its power is great and it will be kept always cool. Because it gives the high speed and required pressure for cut the required metal. The speed of the stream is needed to fix when cut the metal because when it will not get the excess pressure it cannot cut properly the metal.
