  • The Galaxy Tab Vs. the iPad

    Apple captured 73 percent of the tablet market with its 2010 and 2011 iPads, according to Bloomberg Businessweek. The introduction of the iPad3 in March 2012 was the latest salvo in Apple’s campaign to attract additional tablet users and win over laptop fans. The Samsung Galaxy Tab 10.1 is one of the iPad’s leading competitors in the tablet market. It not only competes against the iPad but also other options in the crowded PC tablet market. With only minor differences in weight and screen size, the rivalry between the iPad and Galaxy Tab hinges on their features.

  • How to Hard-Reset a Galaxy Vibrant

    It's useful to perform a hard reset on the Samsung Galaxy S Vibrant smart phone model SGH-T959, to restore original ("factory") default settings. Typically, a person performs a hard reset to clear personal data or downloaded applications in order to re-customize the phone, sell it or ship it for repair. In addition, a hard reset is known to unlock or fix the phone sometimes if it freezes or malfunctions. On the Samsung Vibrant, you perform a hard reset by accessing the phone’s hardware or system menus.

  • How to Download Android 2.3 on Galaxy Vibrant

    The Samsung Vibrant is a Galaxy S Android smartphone that received an upgrade to Android 2.3 in August of 2011. You can upgrade your Vibrant to 2.3 using the Samsung Kies software. Kies also allows you to back up your data from the Vibrant to the computer, in case something goes wrong during the upgrade.

  • How to Install Froyo on a Samsung Galaxy

    Android 2.2, referred to as "Froyo," was sent as an OTA update to Samsung Vibrant (Galaxy S) phones in October 2010. The update was pushed to all subscribers with a data plan and alerted subscribers via the notification bar at the top of the screen. If you did not have a data plan during this time, you can still get Froyo through Samsung's Kies Mini program.

  • About Galaxies in Space

    The Milky Way Galaxy in which we live is not alone in the universe; around 100 billion galaxies exist. A galaxy is a collection of stars, dust and gas, with the average galaxy containing billions of stars. One galaxy may contain a million solar systems such as ours. Some galaxies have smaller galaxies within close proximity, called satellite galaxies. The closest galaxy to the Milky Way is called the Magellanic Clouds; the furthest galaxy from us is 14 billion light years away. Some galaxies occur alone, while others occur in pairs or larger associations known as groups, clusters and superclusters.

  • How to Catch a Tigon on "Monster Galaxy"

    "Monster Galaxy" is a Facebook game developed in the style of "Pokemon" by Gaia Online. The aim is to become a Moga Tamer and capture Mogas by defeating them in battle. Tigons are uncommon Mogas that are difficult to find and even more difficult to capture. Knowing a Moga's stats is essential before attempting to capture it. This helps you decide what Mogas and battle tactics to use. The Tigon's statistics are Zodiac: Gemini; Class: Striker; Attack: 3; Defense: 1; Rarity: Uncommon; Physical Attack: Bodyslam; Upgraded Physical Attack: Piledriver.

  • How Are Scientists Able to Classify Galaxies?

    Scientists have developed a number of classification systems that categorize galaxies based on their observable characteristics. One of the earliest and most widely used methods for classifying galaxies was developed by Edwin Hubble. Hubble's classification system puts galaxies into three main categories based on their apparent shape as seen from the Earth. This system further divides these galaxies based on their specific shape using a system of letters and numbers.

  • Black Hole Games

    Black holes are places in space where the gravity is so strong no objects are able to escape. Giant black holes are located in the center of galaxies. Online black hole games from NASA can teach children about black holes and the dangers they pose. These dark depths also provide challenging obstacles to avoid in online games designed to be played just for fun.

  • How to View the Andromeda Galaxy

    At two million light years away, the Andromeda Galaxy is the furthest object you can see with the naked eye. The galaxy looks like a dim star without any visual aids. You must use binoculars or a telescope to see the elliptical shape of the galaxy. Once you have found the North Star it is easy to locate the Andromeda Galaxy.

  • What Characteristics Are Used to Classify Galaxies?

    Galaxies are classified according to their shape. Astronomer Edwin Hubble is responsible for the classification scheme, which was fully developed in 1936. His work paved the way for the science of cosmology, which is the study of galaxies and the universe as a whole. Hubble's classification diagram is often referred to as the tuning fork due to its branching shape. There are three classifications based on shape, with galaxies not fitting into these groups classified as irregular.

  • What Are S0 Galaxies?

    Also known as a "lenticular galaxy" for its lenslike shape when viewed edge-on, an S0 galaxy is a disc-shaped galaxy with a high bulge-to-disc ratio. They consist largely of old and dying stars, and they are believed by astronomers to be a transitional stage between elliptical galaxies and spiral galaxies.

  • Characteristics of Active Galaxies

    An active galaxy is one which emits more total energy than most galaxies of comparable size. Visually, these galaxies are not very different than their more ordinary neighbors. However, active galaxies emit enormous amounts of energy in wavelengths that the human eye can't see, but scientific instruments can easily detect. Active galaxies fall into one of three categories, though theoretically each category represents the same object simply with a different orientation to Earth.

  • How to Use the Big Dipper to Spot Andromeda

    Whether you glance at the stars occasionally or watch them for hours, knowing how to follow the constellations like a map is a rewarding skill. Like any map, there are keys, and the Big Dipper can be considered a key to finding and identifying other constellations. You can easily spot the Andromeda galaxy if you can identify a few other constellations along the way.

  • Spiral Wound Gasket Installation Procedures

    Spiral wound gaskets are used in industry as static seals in flanged joints, pumps and valves. They are typically well-suited to high pressures and temperatures, but require careful installation if they are to provide leak-free sealing.

  • Why Do Some Spiral-Wound Gaskets Have Inner Rings?

    Spiral-wound gaskets are considered to be the safest type of gasket available because of their sturdy construction. They often consist of a winding material body with metal inner and outer rings, which contain filler material at the inside and outside diameter.

  • Most Massive Galaxies

    The most massive galaxies in the known universe are called giant elliptical galaxies (they are also known as giant diffuse galaxies or brightest cluster galaxies). It's believed these galactic giants "eat" neighboring galaxies that reside within the same galactic cluster, lending them diameters and masses hundreds of times greater than our own Milky Way.

  • How to Boost Your Galaxy DX 959

    A CB radio -- such as the Galaxy DX 959 -- can be very helpful if you spend a lot of time on the road. It can keep you in touch with other drivers, and even receive important safety information, such as weather conditions. But you are going to want to make sure the signal strength on the CB is as strong as possible. This requires installing a good antenna.

  • How Many Galaxies Are Believed to Exist?

    Carl Sagan famously said there are "billions and billions of stars." They are organized into galaxies. According to scientific research and estimates, the number of galaxies is in the billions as well.

  • How to Determine the Age of Spiral Galaxies

    Spiral galaxies, including our Milky Way, have centrally bulging disks with rotating spiral arms. Calculating their exact ages is currently difficult, if not impossible. They cannot be older than the universe -- 13.7 billion years. Spectrometry conducted by the European Southern Observatory (ESO) in Chile shows the Milky Way to be 10 to 13.6 billion years old. Spectrometry is a method to analyze visible light and other electromagnetic radiation from astronomical objects like stars. It measures their concentrations of certain chemical elements and thus helps identify their life cycle stages. It might help date nearby spiral galaxies, or even more…

  • Can We See Any Galaxies From Earth?

    Scientists have calculated that there are over 100 billion galaxies in the visible universe. Our solar system lies within the Milky Way Galaxy, which can be seen from earth with the naked eye. Besides the Milky Way, there are only three other galaxies that you can see without the aid of a telescope.

  • Description of Spiral Galaxies

    Galaxies are classified according to one of four types based on their shape: spiral, elliptical, lenticular or irregular. Spiral galaxies are the most common type of galaxy in the universe, comprising about 77 percent of all observed galaxies, according to Sloan Digital Sky Survey.

  • How do I Identify Galaxies?

    Our solar system is just one of millions of star systems within the Milky Way galaxy. In addition, the Milky Way is one of potentially millions of other galaxies present in the universe. Other named galaxies include the Andromeda Galaxy, Bode's Galaxy, the Cartwheel Galaxy and the Whirlpool Galaxy. Astronomers use galaxy morphological classification (based on shape) to place galaxies in different groups. Galaxy shape can also determine in what stage of its evolution it is in.

  • Names of Distant Galaxies

    Galaxies are vast collections of gas, dust and stars held together by their mutual gravitational forces. Our solar system is part of the Milky Way galaxy. The distance from Earth to the center of our own galaxy is 26,000 light years. Some galaxies are given names inspired by their shape or a distinguishing feature. Others are given names according to a cataloging system. Since galaxies may be mentioned in several catalogs they may have several names.

  • Characteristics of Spiral Galaxies

    Astronomers divide galaxies into three major classes: irregular, elliptical and spiral. Our own galaxy, the Milky Way, falls into the latter category. Spiral galaxies can be subdivided into barred spirals and pure spirals. According to a 2005 article in "New Scientist," the Milky Way is actually a barred spiral galaxy, rather than a pure spiral as was once believed. Regardless of their types, all spirals have certain features in common.

  • Characteristics of Elliptical Galaxies

    For much of our history, humans believed the Earth stood at the center of the universe. It wasn't until fairly recently that we discovered our solar system was only one of many in our galaxy--and our galaxy only one of many in our universe. According to NASA, astronomers now estimate there may be more than 100 billion galaxies in the universe. Galaxies can be broadly divided into three categories: spiral, elliptical and irregular.

  • What Are the Three Basic Types of Galaxies?

    As recently as the end of the 19th century, scientists believed that our home galaxy, the Milky Way, made up the entire universe. Although it is true that the Milky Way contains hundreds of billions of stars separated by vast distances, we now know that it is only one of hundreds of billions of galaxies in the universe. The numbers and the distances involved in the study of galaxies are almost beyond comprehension, but of all the galaxies in the universe, there are only three basic types: spiral, elliptical and irregular.

  • How to Simulate Colliding Galaxies

    A complete guide to simulating galaxy collisions is far more complicated than this article allows. However, a brief overview of key variables is possible. Computer and software must be operational. The central black hole is vital. There are time limits on how long ago galaxies could collide (or exist), and tentative limits to how far into the future galaxy collisions can occur. Dark matter contributes to a galaxy's mass. The nature of dark matter is--as of July 2010--largely unknown. Lastly, remember that, at least in terms of ordinary matter, a galaxy is mostly empty.

  • What Is a Lenticular Galaxy?

    The popular image of a galaxy is a spiral galaxy with arms of newly formed stars, but lenticular galaxies are often forgotten. In the past, galaxies were either spiral or elliptical galaxies--until astronomer Edwin Hubble added lenticular galaxies to the mix in the early 20th century. This new class of galaxies provides a transitional period in galaxy evolution, as it marks a midway point between developing spiral galaxies and stagnant elliptical galaxies.

  • Facts on Elliptical Galaxies

    Elliptical galaxies are one of the three main groups of galaxy classification. Elliptical galaxies (or ellipticals) are quite symmetrical, and vary in appearance from nearly spherical to elongated or flattened ellipsoids. As such, they are classified as E-type galaxies with sub-classes of E0 (spherical) through E7 (flattened). These are older galaxies; ellipticals appear dull and constitute the largest (as well as the smallest) galaxies in our known universe.

  • What Are the Three Shapes of Galaxies?

    Galaxies are giant structures made of dust, gas, stars and other celestial bodies spread through an immense area of space. Our own galaxy, the Milky Way, consists of more than a hundred billion stars strung across tens of thousands of light years. Galaxies are broken down into three basic shapes, with many different subtypes.

  • Myths of Andromeda Galaxy

    Andromeda is the name of a far-off galaxy as well as a princess from Greek mythology who can be seen in the evening sky as one of the constellations. In myth, she is the proverbial maiden in distress, often depicted as a woman chained by the wrists.

  • Facts About Spiral Galaxies

    A spiral galaxy is a star system bound by gravity that resembles a pinwheel, best described as a disc with a bulging center that possesses brighter arms wheeling out from it in a spiral pattern.

  • Facts on Galaxies

    A galaxy is made up of an enormous number of stars, along with gases, dust particles, planets, moons and other assorted heavenly bodies held in place together by gravity. The Earth's solar system is part of the Milky Way galaxy.

  • What Is a Cluster of Galaxies?

    Galaxy clusters, groups of galaxies bound to each other by gravity, hold great interest for astronomers. The stars, gases and dark matter contained within these clusters contain valuable information about how all galaxies are formed.

  • What Are Galaxies Made Of?

    Galaxies such as the Milky Way and Andromeda galaxies consist of many different matters inside of them. Over the last 13 million years, our own galaxy has accrued many interesting trinkets inside of it.

  • Information on Spiral Galaxies

    Astronomers--both amateur and professional--study many different objects in the dark of night. One of the largest, yet most mysterious, is the galaxy. The spiral galaxy is the most noted shape of galaxy for the non-astronomer.

  • Types of Spiral Galaxies

    Galaxies are large collections of stars, dust and gas held together by gravitational forces. Large galaxies may contain billions of stars, while small ones may have just a few hundred. They can be different shapes as well: spiral, elliptical, lenticular or irregular. Our Milky Way galaxy is a type of spiral galaxy, the most common.

  • Types of Galaxies

    Galaxies are large groups of stars and other interstellar matter that occupy space. They're made up of stars, dust and gas held together by gravity. While astronomers don't know exactly how many galaxies there are, they do know the universe we can see probably contains around 100 billion galaxies. Galaxies are classified into three main types: spiral, elliptical and irregular.

  • What Are Elliptical Galaxies?

    As you might guess, elliptical galaxies are named for their shape. Elliptical galaxy shapes range from circular to cigar-shaped. About 10 percent of observed galaxies have been identified as elliptical galaxies. When looked at through a telescope, these galaxies look like little, smooth wads. Lenticular galaxies are often misidentified as elliptical galaxies.

  • Causes of a Galactic Fountain

    A galactic fountain is the result of a series of supernovas within a galaxy. They were first theorized in the 1970s, but recent advances in astrophotography have proven their existence and further expanded their significance. Galactic fountains are credited with creating the galactic halos surrounding galaxies, as well as potentially stimulating star growth.

  • About the Milky Way Galaxy

    The Milky Way Galaxy was first discovered by a philosopher in ancient Greece, Democritus. It is our home in the universe and, even though it has been studied for hundreds of years, there is still much to learn. Scientists today are using a combination of physics and chemistry to look as deep as they can into how the Milky Way was formed in the hope that their discoveries will tell us what the future of the galaxy will be.

  • About Spiral Galaxies

    Eighty percent of the galaxies in the universe can be classified as spiral galaxies. The distinguishing characteristics of spiral galaxies are the appearance of "arms" that seem to spiral around a central bulge of stars and dust--hence the name. The galaxy we live in, the Milky Way, is of the spiral type.

  • Where is Earth in the Universe?

    For many centuries, our ancestors thought the Earth was the center of the universe. Now, science lets us know that our ancestors were incredibly bad guessers. The Earth is located in the Orion Spur off the Perseus Arm in the Milky Way galaxy. Just where the Milky Way galaxy falls in the scope of the entire universe is still to be determined.

  • Where Is Earth's Place in the Galaxy?

    The galaxy is a huge place, so immensely large that it is difficult to imagine the distances between stars. Earth's tiny solar system is often lost among the vast cluster of other stars and heavenly bodies in our galaxy, leading many people to place it incorrectly. Understanding the Earth's place in the galaxy is fundamental to understanding even basic astronomy.

  • How Do Irregular Galaxies Form?

    Galaxies that can't be classified as either spiral or elliptical are called irregular galaxies. This just means that they don't appear to have a recognizable form. Irregular galaxies have many young stars, but a mix of older stars as well. There are two types of irregular galaxies, which are known as Irr I galaxies, and Irr II galaxies. Type I's have some structure, usually in the form of a remnant spiral. The Magellanic Clouds (Large and Small) are examples of dwarf (or small) irregular galaxies. Type II's look very odd, and seem to have no definite structure at all. Astronomers…

  • How to See the Andromeda Galaxy With Binoculars

    The Andromeda Galaxy is the furthest thing from Earth that you can see with the naked eye, being some 2.9 million light years from our planet. To view the Andromeda Galaxy, you first must locate it within the boundaries of the constellation Andromeda. With a pair of binoculars, the Andromeda Galaxy shows up as a hazy, oval patch of light.

  • How to Make a Galaxy

    Tired of the same old galaxy, day after day? Milky Way got you down? Learning how to make a galaxy is not an easy undertaking--unless, of course, the person making it has God-like attributes. If that's the case, learning how to make a galaxy like the Milky Way becomes a relatively simple matter. Here are some easy steps that will help even the most inexperienced galaxy-builder make a great one!
