Groot klip sommer baie naby verby.

Vroeër die week het 2005 YU55 so bietjie meer as 325 000 km van die aarde af verby beweeg. Dit is effens nader as die maan se afstand.

Sonvlekke vir Afrika!

Hou bietjie die sonvlekke dop.  As jy Donderdagaand Sterre en Planete geluister het sou jy die waarskuwing vir die volgende paar dae gehoor het:  GPS, Internetverbindings en selfone gaan in die hek duik en dit as gevolg van al die sonaktiwiteite.

• Loer hoe lyk dit op die son by http://spaceweather.com/.  Wanneer laas was daar so baie aktiwiteit.  Klik op die klein sonnetjie links op die spyskaart.
  
  Onthou dit is gevaarlik om sonder die regte toerusting na die son te kyk. Jy het spesiale filters nodig. Moenie deur `n verkyker of teleskoop direk na die son kyk nie. Jy sal jou sig verloor!

Hot News: Supernova 2011gv in Galaxy IC4901

Supernova 2011gv in Galaxy IC4901

by gregbradley

 

 

This image shows supernova SN2011gv, discovered last week by IceInSpace member Greg Bock as part of the amateur BOSS supernova searching team. The supernova is in the galaxy IC4901, in the constellation Pavo and is marked by the 2 lines near the centre of the galaxy. Greg Bock has taken tens of thousands of images hunting for supernova over the years, and to finally get one must be very satisfying for him. Image by Greg Bradley with an FLI Microline 8300 and Planewave CDK17, 70 mins exposure.

A Photographic Atlas of Selected Regions of the Milky Way

A Photographic Atlas of Selected Regions of the Milky Way
Edward Emerson Barnard, Yerkes Observatory, Wisconsin

Edward Emerson Barnard's Photographic Atlas of Selected Regions of the Milky Way was originally published in two volumes in 1927. Together these volumes contained a wealth of information, including photographic plates of the most interesting portions of the Milky Way, descriptive text, charts, and data. Only 700 copies were printed, making the original edition a collector's item. Reproduced in print for the first time, this edition combines both volumes of Barnard's Atlas. It directly replicates Barnard's text, and contains high resolution images of the original photographic plates and charts, reordered so that they can be seen together. It also includes a biography of Barnard and his work, a Foreword and Addendum by Gerald Orin Dobek describing the importance of the Atlas and additions to this volume, and a pull-out section with a mosaic of all 50 plates combined in a single panorama.
