What's at the Center of the Milky Way?

Jul 22, At its center, surrounded by billion stars and undetectable to the human eye and by direct measurements, lies a supermassive black hole called Sagittarius A*, or Author: Kristina Grifantini. Nov 08, The annotated artist's concept illustrates the new view of the Milky Way. The galaxy's two major arms (Scutum-Centaurus and Perseus) can be seen attached to the ends of a thick central bar, while the two now-demoted minor arms (Norma and Sagittarius) are .

If you look up on a dark, clear night, away from midddle lights, you may see a wide band of faint light stretching above you, stiller than a cloud and glittering with densely packed stars. Translated from the Ancient Greek as "Milky Way" for resembling spilled milk on the sky, that band of light is the center of our galaxy. Mmiddle Milky Way has the shape of a spiral and rotates around its center, with long curling arms surrounding a slightly bulging disk. It's on one of these arms close to the center that the sun and What are the toyota recalls are located.

The entire galaxy is aroundlight-years across. A supermassive black hole is the largest type of black hole in a galaxy, with a mass millions of times that of our sun.

Though it can't be imaged directly because black holes pull in all light, scientists have inferred its presence by looking at the speed and motion of stars and matter close to the galactic center. They have inferred that the movements are influenced by the gravitational pull of a black hole.

No one knows how the black holes at the center of galaxies form, but some suspect that they may begin as a cluster of smaller black holes that merge, or as a smaller black hole that consumes mipky matter to become a supermassive one.

Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA's Spitzer Space Telescope, scientists have discovered that the Milky Way's elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Previously, our galaxy was thought to possess four major arms.

The annotated artist's concept illustrates the new view of the Milky Way. The galaxy's two major arms Scutum-Centaurus and Perseus can be seen attached to the ends of a thick central bar, while the two now-demoted minor arms Norma and Sagittarius are less distinct and located between the major arms.

The major arms consist of the highest densities of both young and old stars; the minor arms are primarily filled with gas and pockets of star-forming activity. The artist's concept also includes a new spiral arm, called the "Far-3 kiloparsec arm," discovered via a radio-telescope survey of gas in the Milky Way. This arm is shorter than the two major arms and lies along the bar of the galaxy.
