Fast Science and Technology, Nov. 21 (Xinhua)-- NASA today released a new image of the center of the Milky way (20MB full-resolution image) taken by the Weber Space Telescope, showing a very gorgeous picture of space.

In the central region is a cluster of ldquo; protostars & rdquo;, which is forming stars, producing an outflow that glows like a bonfire in an infrared dark cloud.

At the center of this young cluster is a previously known massive protostar with a mass more than 30 times that of the sun.

Weber's NIRCam (near Infrared camera) instrument also captured large-scale emission of ionized hydrogen around the lower side of the dark cloud, which appears cyan in the image.

The Milky way is the rod spiral galaxy (a kind of spiral galaxy) in which the solar system is located, with an elliptical disk shape and a huge disk structure. the latest research shows that the Milky way has four clear and quite symmetrical spiral arms, which are 4500 light-years apart. The total number of stars is between 100 billion and 400 billion.

The total mass of the Milky way is about 1.5 trillion times the mass of the sun, and the age of the Milky way is about 10 billion years old.
