This means that giant radio galaxies are probably far more common than we thought!” ![]() “Based on our current knowledge of the density of giant radio galaxies in the sky, the probability of finding two of them in this region is less than 0.0003 per cent. ![]() “We found these giant radio galaxies in a region of sky which is only about 4 times the area of the full Moon,” said Jacinta Delhaize, lead study author and research fellow at the University of Cape Town, in a statement. NASA/JPL-CaltechĪ stream of nearly 500 stars in the Milky Way is actually a family This arm is shorter than the two major arms and lies along the bar of the galaxy.Our sun lies near a small, partial arm called the Orion Arm, or Orion Spur, located between the Sagittarius and Perseus 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. 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. Previously, our galaxy was thought to possess four major arms.This artist's concept illustrates the new view of the Milky Way, along with other findings presented at the 212th American Astronomical Society meeting in St. ![]() 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. Early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. ![]()
