| 説明 | A close cropping of spiral galaxy M101 shows an array of stunning details have never been seen before in this galaxy. Due to the high sensitivity and fine resolution of Hubble's Advanced Camera for Surveys (ACS), individual dust lanes in the spiral arms are as clearly visible as rivers flowing through a mountain range here on Earth taken from an aerial photo. Bright, hot regions that are areas of active star formation also dot the spiral arms, akin to ground photos of the bright lights of major cities when photographed at night.Several bright stars appear in this small section of M101 (also known as the Pinwheel Galaxy). They are in our own galaxy, superimposed in the line of sight and appear much brighter than the stars within M101 because they are so much closer. So too, a background spiral galaxy, millions of light-years behind M101, appears between two spiral arms.06-10 |
