Image caption:
This image shows the remnant of the supernova SN 1006. This was probably the result of a white dwarf that accreted so much material from a binary companion star that the white dwarf exploded (this is called a Type 1a supernova by astronomers). This explosion happened several thousand years ago, however it took time for the light from this event to reach Earth, only arriving in the year 1006. This bright explosion was noticed by observers across the Earth and its appearance was noted in the records of many different societies.
Here we see the effect that supernova has had on its surroundings in the galaxy. The force of the explosion has blown a huge bubble in the surrounding interstellar gas with a hot shockwave at its edge. The image appears to be a simple color picture but it actually represents light far beyond what our eye can see. The blue is X-ray data from NASA's Chandra X-ray Observatory, the yellow and orange are data from optical telescopes and the red is detections in radio waves from the Very Large Array and the Green Bank Telescope. The bright blue of the outer shell shows the gas there is very hot and that the explosion produced energetic shock waves.

Image caption: Dieses Bild zeigt den Überrest der Supernova SN 1006. Wahrscheinlich waren sie das Ergebnis eines Weißen Zwerges, der so viel Material von einem binären Begleitstern akkretierte, dass der Weiße Zwerg explodierte (dies wird von den Astronomen als Supernova vom Typ 1a bezeichnet). Diese Explosion ereignete sich vor mehreren tausend Jahren, aber es dauerte lange, bis das Licht dieses Ereignisses die Erde erreichte und erst im Jahr 1006 ankam. Diese helle Explosion wurde von Beobachtern auf der ganzen Erde bemerkt, und ihr Erscheinen wurde in den Aufzeichnungen vieler verschiedener Gesellschaften vermerkt.
Hier sehen wir die Auswirkungen, die die Supernova auf ihre Umgebung in der Galaxie hatte. Die Kraft der Explosion hat eine riesige Blase in das umgebende interstellare Gas gesprengt, an deren Rand sich eine heiße Schockwelle gebildet hat. Das Bild scheint ein einfaches Farbbild zu sein, aber es repräsentiert tatsächlich Licht, das weit über das hinausgeht, was unser Auge sehen kann. Das Blaue sind Röntgendaten des Chandra-Röntgenobservatoriums der NASA, das Gelbe und das Orange sind Daten von optischen Teleskopen und das Rote sind Entdeckungen von Radiowellen des Very Large Array und des Green Bank Teleskops. Das helle Blau der äußeren Hülle zeigt, dass das Gas dort sehr heiß ist und dass die Explosion energiereiche Schockwellen erzeugt hat.

Image caption: Questa immagine mostra il residuo della supernova SN 1006. Si tratta probabilmente del risultato di una nana bianca che ha accumulato così tanto materiale da una stella binaria compagna che la nana bianca è esplosa (gli astronomi la chiamano supernova di tipo 1a). L'esplosione è avvenuta diverse migliaia di anni fa, ma la luce di questo evento ha tardato a raggiungere la Terra, arrivando solo nell'anno 1006. Questa brillante esplosione è stata notata dagli osservatori di tutta la Terra e la sua comparsa è stata annotata nei registri di molte società diverse.
Qui vediamo l'effetto che la supernova ha avuto sull'ambiente circostante nella galassia. La forza dell'esplosione ha fatto deflagrare un'enorme bolla nel gas interstellare circostante, con un'onda d'urto calda ai suoi margini. L'immagine sembra essere una semplice foto a colori, ma in realtà rappresenta una luce che va ben oltre quella che il nostro occhio può vedere. Il blu è costituito da dati a raggi X provenienti dal Chandra X-ray Observatory della NASA, il giallo e l'arancione da dati provenienti da telescopi ottici e il rosso da rilevamenti in onde radio provenienti dal Very Large Array e dal Green Bank Telescope. Il blu brillante del guscio esterno mostra che il gas è molto caldo e che l'esplosione ha prodotto onde d'urto energetiche.
