Galaxy Planets 3D

A wonderful vision on distant galaxies of space awaits you in this beautiful animated wallpaper. The classic 3D simulation of galaxies would require a great quantity of computing power but in this app this problem was circumvented utilizing a lightweight and innovative algorithm that simulates the mechanics of galaxies. The animation of the images is breathtaking and you will surely love this live wallpaper.

We should really expand our horizont on what galaxies are to fully understand the nature and the universe.

For example, did you know that if you hold a grain of sand up, the area of sky that it covers contains as many as 10.000 galaxies?

A galaxy is a gravitationally bound system consisting of stars, stellar remnants, an interstellar medium of gas and dust, and dark matter.

Many galaxies are believed to have black holes at their active center. The Milky Way's central black hole, known as Sagittarius A, has a mass four million times that of our Sun.

Most galaxies are 1,000 to 100,000 parsecs in diameter and usually separated by distances on the order of millions of parsecs (or megaparsecs).

Galaxies come in three main types: ellipticals, spirals, and irregulars. A slightly more extensive description of galaxy types based on their appearance is given by the Hubble sequence. Since the Hubble sequence is entirely based upon visual morphological type, it may miss certain important characteristics of galaxies such as star formation rate in starburst galaxies and activity in the cores of active galaxies.

Active distant galaxies that emit high-energy radiation in the form of x-rays are classified as Seyfert galaxies or quasars, depending on the luminosity. Blazars are believed to be an active galaxy with a relativistic jet that is pointed in the direction of Earth. A "radio galaxy" emits radio frequencies from relativistic jets. A unified model of these types of active galaxies explains their differences based on the viewing angle of the observer.

Stars are created within galaxies from a reserve of cold gas that forms into giant molecular clouds. Some galaxies have been observed to form stars at an exceptional rate, known as a starburst.

Spiral galaxies that you will find on this app resemble spiraling pinwheels. Though the stars and other visible material contained in such a galaxy lie mostly on a plane, the majority of mass in spiral galaxies exists in a roughly spherical halo of dark matter that extends beyond the visible component, as demonstrated by the universal rotation curve concept. "Spiral galaxies" consist of a rotating disk of stars and interstellar medium, along with a central bulge of generally older stars. Extending outward from the bulge are relatively bright arms. A galaxy with poorly defined arms is sometimes referred to as a flocculent spiral galaxy, in contrast to the grand design spiral galaxy that has prominent and well-defined spiral arms.

Peculiar galaxies are galactic formations that develop unusual properties due to tidal interactions with other galaxies. An example of this is the ring galaxy, which possesses a ring-like structure of stars and interstellar medium surrounding a bare core. What is called a "ring galaxy" is thought to occur when a smaller galaxy passes through the core of a spiral galaxy. Such an event may have affected the Andromeda Galaxy, as it displays a multi-ring-like structure when viewed in infrared radiation.

Despite the prominence of large elliptical and spiral galaxies, most known galaxies in the Universe are dwarf galaxies. These galaxies are relatively small when compared with other galactic formations, being about one hundredth the size of the Milky Way, containing only a few billion stars. Ultra-compact dwarf galaxies have recently been discovered that are only 100 parsecs across.</br></br></br></br></br></br></br></br></br></br></br></br></br></br></br>
