Milky Way Galaxy

Graphic view of our milky way galaxy.

Milky way galaxy. It is nearly 120000 light years across and a shining example of a spiral galaxy. It lies about 8 kpc from the center on what is known as the orion arm of the milky way. This glow results from a vast sea of cosmic ray particles slamming into interstellar gas and dust generating gamma rays. The milky way is the galaxy that contains the solar system with the name describing the galaxys appearance from earth.

Our sun a star and all the planets around it are part of a galaxy known as the milky way galaxya galaxy is a large group of stars gas and dust bound together by gravitythey come in a variety of shapes and sizes. The milky way galaxy is organized into spiral arms of giant stars that illuminate interstellar gas and dust. The milky way galaxy is home to 400 billion stars and our own sun and solar system. The milky way is about 1000000000000000000 km about 100000 light years or about 30 kpc across.

Milky way galaxy sometimes simply called the galaxy large spiral system of about several hundred billion stars one of which is the sun. The milky way is a large barred spiral galaxy. The milky way galaxy is most significant to humans because it is home sweet home. Not only does it measure some 120000180000 light years in diameter it is home to planet earth the birthplace of humanity.

Not counting transient events such as gamma ray bursts the brightest object in the gamma ray sky is the plane of our milky way galaxy. In fact 75 of the gamma rays in our galaxy come from these cosmic. The sagittarius dwarf galaxy will probably not be the first galaxy that has been eaten by our galaxy. The sun is in a finger called the orion spur.

A hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eyethe term milky way is a translation of the latin via lactea from the greek galaxias kyklos galaxias kyklos milky circle. The milky way galaxy is an immense and very interesting place. It takes its name from the milky way the irregular luminous band of stars and gas clouds that stretches across the sky as seen from earth. The sloan digital sky survey for instance report that outside of the galaxy there are huge clumps of stars that appear to be the remains of smaller galaxies that were ripped apart by the milky way more than a billion years ago.
