The Milky Way is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.The term Milky Way is a translation of the Latin via lactea, from the Greek γαλαξίας κύκλος (galaxías kýklos), meaning "milky circle". Sep 4, 2023 tif (7.18 MB) Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way.

Our Sun is located nearly 27,000 light-years from the Milky Way's nucleus, or about halfway between its center and the edge. Our Solar System is placed between two main arms — Scutum-Centaurus and Perseus, within the small partial arm named the Orion Arm or Orion Spur. This arm is about 3,500 light-years wide and more than 20,000 light. 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. Although Earth lies well within the Milky Way Galaxy (sometimes simply called the Galaxy), astronomers do not have as complete an understanding of its nature as they do of some external star systems. Milky Way quick facts: - Galaxy type: Barred spiral - Age: 13.6 billion years (and counting) - Size: 100,000 light-years across - Number of stars: about 200 billion - Rotation time: 250 million. Author: Richard Bartlett Views: 3707 At some point or another, you've probably looked up and noticed a grey, misty band stretching overhead. This mistiness appears irregular, ill-defined, and quite elusive, with bright clumps in some parts and dark patches in others.

Both are correct. Both refer to our home galaxy, our local island in the vast ocean of the universe, composed of hundreds of billions of stars, one of which is our sun. Long ago, it was possible. The Milky Way. Our galaxy, the Milky Way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and at least ten times as much dark matter as all the stars and gas put together. And it's all held together by gravity. Like more than two-thirds of the known galaxies, the Milky Way has a spiral shape. The Milky Way Galaxy. This image is from observations made by the COBE satellite. COBE was launched by NASA in November, 1989. It was designed to study the radiation believed to be a remnant of the explosion that started the expansion of the Universe. In scientific terms, it measured the diffuse infrared and microwave background radiation. As our planet whirls around the sun, the whole solar system undertakes a far grander voyage, circling our island universe every 200 million years. Weaving our way through the disc of the Milky Way.

Generally speaking, the best time to see the Milky Way is during the Milky Way season, which goes from February to October, usually between 00:00 and 5:00, and on nights with a new moon. This, however, will vary depending on the hemisphere, your latitude, and other factors like the moon phase.
