    Globular clusters are famous for their high concentration of stars: think of the cosmic void, then meet these regions with up to a million of stars so closely packed together by gravity and you will be amazed by globular clusters!

    Among the galactic globular clusters Messier 15 is likely the most dense object of that kind and its nucleus undergone a core collapse and the central region is so concentrated that, accordingly to several studies, it could host a black hole.

    Messier 15 is located at about 33.000 light years from us and was discovered by Jean-Dominique Maraldi in 1746.

    The image above comes from the average of 17, 120-seconds unfiltered and unguided exposures, remotely taking using the PlaneWave 17″ robotic unit part of the Virtual Telescope.

    Comet C/2009 P1 (Garradd) and M15 (2011)

    This image shows comet Garradd while apparently meeting the globular cluster Messier 15 in Pegasus, on 2 Aug. 2011. A mosaic with two images was done, in order to cover both the objects, still having a nice resolution.

    They were captured with the PW17 unit, part of the Virtual Telescope Project. Both images used were integrated for one minute each. The optical tube is installed on a Paramount ME mount. The CCD camera is a SBIG STL-6303E. The image scale is of 1.26 “/pixel.

    Destination: Comet Garradd

    After quite a long absence, an interesting comet was coming again, its name being C/2009 P1 (Garradd). Discovered by the australian astronomer Gordon J. Garradd on 13 aug 2009, this comet will be interestingly bright over the next few months.

    The Virtual Telescope staff planned an exclusive online event, making possible for all to observe the comet in real time thanks to our cutting edge technologies.

    The event was in English and it was scheduled for 21 Sept. 2011, at 18:30 UT. After a fascinating introduction to the history and science of comets, comet Garradd was observed in real time, with our new, amazing telescope, with the live commentary from our acclaimed scientific staff.
