Οι 4 κομήτες που «κυκλοφορούν» στη γειτονιά μας, Morning Comets Continue to Dazzle in New Images, Timelapses

Comet ISON C/2012 S1 On October 31st, 09:17-34 UTC. Coma much denser now around the nucleus and possibly both tails (Ion, Dust) on negative image (lower right) 17 x 1 minute exposures. Credit and copyright: Efrain Morales/Jaicoa Observatory

Εκτός από τον αναμενόμενο κομήτη ISON, αυτές τις ημέρες εμφανίζονται κι άλλοι τρεις κομήτες στον ουρανό: ο 2013 R1 Lovejoy, ο 2P/Encke και ο 2012 X1 LINEAR! Δυστυχώς κανένας από αυτούς δεν είναι ακόμη ορατός γυμνό μάτι. Υπάρχουν όμως πολύ εντυπωσιακές φωτογραφίες από ερασιτέχνες αστροφωτογράφους:

Δυο φωτογραφίες μαζί, 25 και 28 Οκτωβρίου 2013: ο κομήτης 2012 X1 Linear. These new images will be shared as part of the collaboration with Ernesto Guido, Nick Howes and Martino Nicolini (Remanzacco Observatory and Faulkes Telescopes Project).

Και δυο βίντεο με τον κομήτη ISON:

A short timelapse video, covering 69 minutes of imaging time from astronomical darkness state to civil twilight state, on 27 October 2013. From the video you can see the reduced visibility of Comet ISON as the sky was becoming brighter gradually. Moon was also visible with an illumination of about 50%. The nucleus of Comet ISON is still intact and its current magnitude is about 8. You will also see an image as a result of stacking 46 images together as well as an inverted image in the video. NGC 3428 is also visible in the video near the two brightest stars on the lower left.
