Volksblad : Seldsame verskynsel in hemelruim te sien


23 Mei 2013 18:00 - Westelike horison - Jupiter bo, Venus en Merkurius onder

Volksblad : Seldsame verskynsel in hemelruim te sien

KAAPSTAD. – Venus, Jupiter en Mercurius gaan binnekort ’n dans in die lugruim uitvoer om uiteindelik ’n driehoek te vorm.
Dié planete sal van 22 Mei af saans sowat ’n halfuur tot ’n uur ná sonsondergang mooi begin wys.
Maar moenie 26 Mei misloop nie, want dán sal die drie op hul mooiste wees.
Die vorige keer wat die drie plante só ’n driehoek gevorm het, was in Mei 2011.
Ná vandeesmaand sal dit eers weer in Oktober 2015 sigbaar wees, volgens dr. Tony Phillips van Nasa.
Willie Koorts van die Suider-Afrikaanse Sterrewag (Saao) sê ’n mens moet laag op die horison kyk en eers soek na Venus, die helderste van die drie.
Die driehoek sal mooi sigbaar wees, selfs sonder ’n teleskoop, maar dit sal mooier deur ’n verkyker wees.

Chelyabinsk Meteor Flash



Chelyabinsk Meteor Flash

Explanation: A meteoroid fell to Earth on February 15, streaking some 20 to 30 kilometers above the city of Chelyabinsk, Russia at 9:20am local time. Initially traveling at about 20 kilometers per second, its explosive deceleration after impact with the lower atmosphere created a flash brighter than the Sun. This picture of the brilliant bolide (and others of its persistent trail) was captured by photographer Marat Ametvaleev, surprised during his morning sunrise session creating panoramic images of the nearby frosty landscape. An estimated 500 kilotons of energy was released by the explosion of the 17 meter wide space rock with a mass of 7,000 to 10,000 tons. Actually expected to occur on average once every 100 years, the magnitude of the Chelyabinsk event is the largest known since the Tunguska impact in 1908.
