Astronomie - Die ersten Bilder von Venus-Transit

 

Hier in Mannheim war just zu der Sichtbarkeit des Venus-Transit der Himmel dicht bewölkt (wie schon vermutet, wenn auch am Abend davor der Mond zu sehen war...), und so erfreuen wir uns an den ersten Bilder der NASA:

 

 

 

 

This movie shows the transit of Venus on 5-6 June 2012 as seen from SWAP, a Belgian solar imager onboard ESA’s PROBA2 microsatellite. SWAP, watching the Sun in EUV light, observes Venus as a small, black circle, obscuring the EUV light emitted from the solar outer atmosphere – the corona – from 19:45UT onwards. At 22:16UT – Venus started its transit of the solar disk
The bright dots all over the image (‘snow storm’) are energetic particles hitting the SWAP detector when PROBA2 crosses the South Atlantic Anomaly, a region where the protection of the Earth magnetic field against space radiation is known to be weaker.
Note also the small flaring activity in the bright active region in the northern solar hemisphere as Venus passes over. Towards the end, you can see a big dim inverted-U-shape moving away from the Sun towards the bottom-right corner. This is a coronal mass ejection taking off.

Und da im Norden von Europa schöneres Wetter war können wir diese schöne Aufnahme von Ole Henningsen abbilden, welche er auf Lolland-Falster/Dänemark machte.
