- The core of our galaxy Staring to the Sagittarius region during a clear summer night is always a moving experience. Naked eye cannot count the stars. But a good pair of binoculars is enough to literally lose one's reason and begin a floating travel into the deep space. This is the thickest part of our galaxy, its core. This film, Fujichrome 1600, has been exposed for 17 minutes. Optic used is a 24 mm. Guided on equatorial mount.

Galaxy A galaxy is a large collection of stars, glowing nebulae (clouds), gas, and dust bound together by gravity. Many scientists now believe that a black hole, the remains of a massive star, lies at the center of many galaxies. Galaxies are as plentiful in the universe as grains of sand on a beach.

- The core collapse of a massive star  comences as the core has finished fusing the rest of its fuel into iron, the last and heaviest element forged in high-mass stars. At this p…oint the risidual energy put out by the fusing of elements is not worth the energy it takes to fuse them together. A Black Hole.

The galaxy The galaxy, as it was commonly referred to, was one of the trillions of galaxies in the universe. The galaxy was a vast composite of over 400 billion estimated stars and over 3.2 million habitable systems orbiting around a super-massive black hole at the heart of the galaxy. The galactic arms rotated around this black hole across a diameter of over 100,000 light years.

University of California, San Diego Center for Astrophysics & Space Sciences Spiral Structure Spiral Arms Since the Earth lies in the disk of the Milky Way, dust prevents us from determining the large scale structure of the Galaxy's spiral pattern beyond a few thousand light-years.

What is Sagittarius A? At the very heart of the Milky Way is a region known as Sagittarius A. This region is known the be the home of a supermassive black hole with millions of times the mass of our own Sun. And with the discovery of this object, astronomers have turned up evidence that there are supermassive black holes at the centers most most spiral and elliptical galaxies.

Jupiterâs Core Jupiter’s core contains some rock and hydrogen metals. Scientists can not be 100 percent certain if deep within the planet there is a solid core or not, but based on gravitational measurements compared with Earth’s, the best educated guesses possible based on those measurements say there is no solid core.

- Above the outer core is the Earth's mantle. The geodynamo is the mechanism thought to be responsible for the electric current in the core and the generation of the Earth's magnetic field through the convection of conducting fluids in the Earth's core. Other planets with a molten metal core can also have a magnetic field. See related links.

About the Earth's Core What the Core Is Made Of. Considering that the whole Earth on average consists of the same mixture of stuff we see elsewhere in the solar system, the core has to be iron metal along with some nickel. But it's less dense than pure iron, so about 10 percent of the core must be something lighter.

Equinox A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias (γαλαξίας), literally milky, a reference to the Milky Way. Galaxies range in size from dwarfs with just a few billion (109) stars to giants with one hundred trillion (1014) stars, each orbiting its galaxy's center of mass.

Massive Young Stars at Milky Way's Center Puzzle Scientists Massive Young Stars at Milky Way's Center Puzzle Scientists. A puzzling characteristic of the our galactic center (GC) is the fact that it hosts the three most massive clusters of young stars in the entire galaxy. The Central, Arches (above) and Quintuplet clusters each contain hundreds of young, hot stars that are much larger than the Sun.

Main sequence Stars on this band are known as main-sequence stars or dwarf stars. These are the most numerous true stars in the universe, and include the Earth's Sun. After condensation of mass and ignition of a star, it generates thermal energy in the dense core region through nuclear fusion of hydrogen atoms into helium.

- Warlord Zaela. The Molten Core is a level 60 raid dungeon located within Blackrock Mountain, home to Ragnaros the Firelord. It was one of two forty (40) player raid dungeons available upon release of World of Warcraft, the other being Onyxia's Lair.he Molten Core in the TCG. The Molten Core consists of rock and lava, with the lava forming rivers, small lakes and lavafalls. Other features are small volcano-like smoke vents, molten cracks in the walls and roof, occasional dark iron deposits, and the runes of warding.

A Star is Born A Star is Born Stars form in the densest regions of the interstellar medium, or ISM, called molecular clouds. The ISM is the name given to the gas and dust that exists between the stars within a galaxy. It is 99% gas and 1% dust, by mass. Properties of ISM gas in our region of the Milky Way Galaxy:

Finally, a Solid Look at Earth's Core The core is thought to be a two-part construction. The inner core is solid iron, and that's surrounding by a molten core, theory holds. Around the core is the mantle, and near the planet's surface is a thin crust — the part that breaks now and then and creates earthquakes.

Galaxies: Collisions, Types & Other Facts Other galaxies may contain objects like quasars, the most energetic bodies in the universe, at their core. Astronomers aren't certain of exactly how galaxies formed. After the Big Bang, space was made up almost entirely of hydrogen and helium.

What Is the Outer Core? The outer core consists of hot lava that is comprised mostly of iron and nickel. This layer is so hot that all metals in it are in a liquid state. Iron and nickel are common metals found across the planet, and these metals exist in solid form on the Earth's surface. In the outer core, they form an alloy.

Jupiter's Core Twice as Big as Thought At the center of the rocky core is probably a metallic ball of iron and nickel, just like Earth's core. Our simulations show there is a big rocky object in the center surrounded by an ice layer and hardly any ice elsewhere in the planet, Militzer said.

Inner core Inner core. The Earth's inner core is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 70% of the Moon's radius.[1][2] It is composed of an iron–nickel alloy and some light elements.

What is earths core? The Earth's core is that portion of the Earth which is composed primarily of iron (86 %) and Nickel (10 %) with a mixture of other elements making up the remainder. The Eart … h's core is split into two. The outer core, which is a liquid and the inner core, which is a solid.

- Geologists hypothesize that the Earth's center is composed of predominantly iron. The outer portion of the center, known as the outer core, is thought to be liquid iron. While the interior portion of the center, known as the inner core is thought to be solid iron.cientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid.

Largest Structure In Universe, Large Quasar Group, Challenges Cosmological Principle Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretches 4 billion light-years from end to end. The structure is a large quasar group (LQG), a collection of extremely luminous galactic nuclei powered by supermassive central black holes.

How Do We Know What's in the Earth's Core? PM Explains The core's heat is mostly due to the slow decay of radioactive elements left over from when the planet first formed. The molten iron outer core lies about 3000 kilometers below our feet, while the solid iron inner core is another 2000 kilometers further down. A few other elements, including oxygen and silicon, are thrown in for good measure. But for the most part, iron rules the Earth's underbelly.

Whatâs the Closest Galaxy to Us The Andromeda Galaxy (M31) is a spiral galaxy and the most massive galaxy in our Local Group of galaxies. Our Local Group of galaxies is made up of roughly 46 galaxies, most of which are not as large or even close to the size as the Andromeda Galaxy, making it the biggest, baddest and most awesomest galaxy in our Local Group.
