This page describes an image Hello Comet, shall we dance?, by Robert Barsa, Slovakia
Image caption:
Third place in the 2021 IAU OAE Astrophotography Contest, category Comets.
This beautiful and poetic image taken from Slovakia in July 2020 captures the comet C/2020 F3 (Neowise). The direction of the tails of the comet provides a clue as to the position of the Sun. In the past, the appearance of a comet in the skies could be accompanied by apprehension and even fear from those who did not know what these objects really are. Through careful observations and the applications of knowledge from physics, chemistry and geology, we now understand that comets are objects left over from the earliest days when the Solar System formed. The most distinctive features of a comet are the bluish ion (gas) tail, and whitish dust tail, which can extend for tens of millions of kilometres. These distinctive features, easily observable with the unaided eye together with an understanding of the science, are no longer cause for fear, rather they help us understand the history of our Solar System, and bring awe, joy and contemplation, as portrayed in this image.

Image caption: ২০২১ আইএইউ ওএইঅ্যাস্ট্রোফটোগ্রাফি প্রতিযোগিতায় তৃতীয় স্থান, ধূমকেতু বিভাগে।
২০২০ সালের জুলাই মাসে স্লোভাকিয়া থেকে তোলা এই সুন্দর এবং কাব্যিক চিত্রটি ধূমকেতু সি/২০২০ এফ৩ (নিওয়াইজ) ক্যাপচার করে। ধূমকেতুর লেজের দিক সূর্যের অবস্থান সম্পর্কে একটি সূত্র প্রদান করে। অতীতে, আকাশে ধূমকেতুর আবির্ভাব শঙ্কা এবং এমনকি যারা এই বস্তুগুলি আসলে কী তা জানত না তাদের কাছ থেকে ভয়ও হতে পারে। সতর্ক পর্যবেক্ষণ এবং পদার্থবিদ্যা, রসায়ন এবং ভূতত্ত্ব থেকে জ্ঞানের প্রয়োগের মাধ্যমে, আমরা এখন বুঝতে পারি যে ধূমকেতু হল সৌরজগতের প্রথম দিন থেকে অবশিষ্ট বস্তু। ধূমকেতুর সবচেয়ে স্বতন্ত্র বৈশিষ্ট্য হল নীলাভ আয়ন (গ্যাস) লেজ এবং সাদা ধূলিকণার লেজ, যা লক্ষ লক্ষ কিলোমিটার পর্যন্ত বিস্তৃত হতে পারে। এই স্বাতন্ত্র্যসূচক বৈশিষ্ট্যগুলি, বিজ্ঞানের বোঝার সাথে একত্রে সাহায্যবিহীন চোখ দিয়ে সহজেই পর্যবেক্ষণ করা যায়, এখন আর ভয়ের কারণ নয়, বরং তারা আমাদের সৌরজগতের ইতিহাস বুঝতে সাহায্য করে এবং এই ছবিতে চিত্রিত হিসাবে বিস্ময়, আনন্দ এবং মনন নিয়ে আসে .

Image caption: Terzo posto al Concorso Astrofotografico IAU OAE 2021, categoria Comete.
Questa bella e poetica immagine ripresa dalla Slovacchia nel luglio 2020 cattura la cometa C/2020 F3 (Neowise). La direzione delle code della cometa fornisce un indizio sulla posizione del Sole. In passato, l'apparizione di una cometa nei cieli poteva essere accompagnata da apprensione e persino paura da parte di chi non sapeva cosa fossero realmente questi oggetti. Grazie ad attente osservazioni e all'applicazione delle conoscenze di fisica, chimica e geologia, oggi sappiamo che le comete sono oggetti che risalgono ai primi tempi della formazione del Sistema Solare. Le caratteristiche più distintive di una cometa sono la coda bluastra di ioni (gas) e la coda biancastra di polvere, che può estendersi per decine di milioni di chilometri. Queste caratteristiche peculiari, facilmente osservabili a occhio nudo e con una buona conoscenza della scienza, non sono più motivo di paura, ma piuttosto ci aiutano a comprendere la storia del nostro Sistema Solare e ci suscitano stupore, gioia e contemplazione, come mostra questa immagine.
