[M106]

[M106, Bill Keel] [PNG]

The bright spiral galaxy M106 (NGC 4258) in Ursa Major. This system is distinguished by "anomalous arms", better described perhaps as jets, seen curving outward through the disk in radio emission and optical emission lines. Recent measurements of maser regions near the nucleus suggest a supermassive dark object (a black hole candidate with mass of order 100 million solar masses) at the center of this galaxy. This pseudocolor rendition was made from a V-band CCD frame covering a region 9 arcminutes square, taken with the 1.1-meter Hall telescope of Lowell Observatory.

    Details in the central region of M106.

    The central part of M106, photographed in the blue light. This central region is of much higher surface brightness than the outlayers of this galaxy. Dust is evident.

    [M106 in IR, Univ. Oregon]

    This is an I-band image (effective wavelength around 8500 Angstroms) of the whole galaxy. The morphology in this image appears much smoother as the old stellar population (more smoothly distributed) dominates the light in this passband.

    Both iamges are from the University of Oregon collection.

    [M106, AOP/KPNO Visitor Center]
    Hi-res version

    This gorgeous image was taken by Ron and Beth Sharer on February 4, 2000 when participating in the Kitt peak Visitor Center's Advanced Observing Program, using the AOP's Meade 16in LX200 telescope operating at f/6.3 and SBIG ST8E CCD camera with color filter wheel. M106's appearance is dominated by two bright spiral arms and dark dust lanes near the nucleus. Bright newly formed stars near their outer tips distinguish the spiral arms in this photograph, the young star clusters seen as blue patches, the nebulae which still form stars as reddish or pinkish spots. The older population gives the nuclear region a more yellowish appearance.

    [M106, KPNO]

    Spiral galaxy M106 as photographed with the Burrell Schmidt telescope of Case Western Reserve University's Warner and Swasey Observatory, located on Kitt Peak, near Tucson, Arizona. This is a full-color composite created from nine images taken in the BVR pass-bands, taken in June 1996 during the Research Experiences for Undergraduates (REU) program.
