Image caption:
At the heart of the Crab Nebula, situated approximately 6,500 light-years away in the constellation of Taurus, lies the Crab Nebula Pulsar. This is remnant of a massive star that exploded at the end of its life. This happened several thousand years ago but the light from this explosion only reached the Earth in the year 1054. This celestial event was viewed by people across the world with many different societies noting it in their records.
The Crab Nebula Pulsar rotates about 30 times per second and emits light in many different wavelengths, including the visible spectrum. It is roughly one and a half times the mass of the sun but the force of the explosion that formed it crammed this mass into a tiny space, roughly ten kilometres in radius.
This image is a composite of several observations conducted by the Gemini North observatory in Hawaii, USA. The pulsar can be seen at the center. The observations that this image was created from were taken over a period of five years. Data from 2009 is shown in blue and data from 2014 is shown in red. Over this time material has flowed away from the pulsar resulting in this colored ripple effect. Again the colors do not show real colors in the image, the ripples show the positions of the shockwaves as they moved away from the pulsar and hit into the surrounding gas.

Image caption: Im Herzen des Krebsnebels, der etwa 6.500 Lichtjahre entfernt im Sternbild Stier liegt, befindet sich der Krebsnebel-Pulsar. Er ist der Überrest eines massereichen Sterns, der am Ende seines Lebens explodierte. Dies geschah vor mehreren tausend Jahren, aber das Licht dieser Explosion erreichte die Erde erst im Jahr 1054. Dieses Himmelsereignis wurde von Menschen auf der ganzen Welt beobachtet und von vielen verschiedenen Gesellschaften in ihren Aufzeichnungen festgehalten.
Der Krebsnebel-Pulsar rotiert etwa 30 Mal pro Sekunde und strahlt Licht in vielen verschiedenen Wellenlängen ab, darunter auch im sichtbaren Spektrum. Er hat etwa die anderthalbfache Masse der Sonne, aber die Kraft der Explosion, die ihn geformt hat, hat diese Masse auf einen winzigen Raum mit einem Radius von etwa zehn Kilometern gepresst.
Dieses Bild ist eine Zusammenstellung mehrerer Beobachtungen, die vom Gemini North Observatorium auf Hawaii (USA) durchgeführt wurden. Der Pulsar ist in der Mitte zu sehen. Die Beobachtungen, aus denen dieses Bild erstellt wurde, wurden über einen Zeitraum von fünf Jahren aufgenommen. Die Daten aus dem Jahr 2009 sind blau und die Daten aus dem Jahr 2014 sind rot dargestellt. In dieser Zeit ist Material vom Pulsar weggeflossen, was zu diesem farbigen Ripple-Effekt geführt hat. Auch hier zeigen die Farben keine echten Farben im Bild, sondern die Wellen zeigen die Positionen der Schockwellen, die sich vom Pulsar wegbewegen und auf das umgebende Gas treffen.

Image caption: Nel cuore della Nebulosa del Granchio, situata a circa 6.500 anni luce di distanza nella costellazione del Toro, si trova la Pulsar della Nebulosa del Granchio. Si tratta del resto di una stella massiccia che è esplosa alla fine della sua vita. Ciò avvenne diverse migliaia di anni fa, ma la luce di questa esplosione raggiunse la Terra solo nell'anno 1054. Questo evento celeste è stato visto da persone di tutto il mondo e molte società diverse lo hanno annotato nei loro documenti.
La pulsar della Nebulosa del Granchio ruota circa 30 volte al secondo ed emette luce in diverse lunghezze d'onda, compreso lo spettro visibile. La sua massa è circa una volta e mezza quella del Sole, ma la forza dell'esplosione che l'ha formata l'ha stipata in uno spazio minuscolo, di circa dieci chilometri di raggio.
In questa immagine sono assemblate diverse osservazioni condotte dall'osservatorio Gemini North alle Hawaii, negli Stati Uniti. La pulsar è visibile al centro. Le osservazioni da cui è stata creata questa immagine sono state effettuate nell'arco di cinque anni. In blu sono riportati i dati del 2009 e in rosso quelli del 2014. In questo lasso di tempo il materiale si è allontanato dalla pulsar dando origine a questo effetto di increspatura colorata. Anche in questo caso i colori non mostrano i colori reali dell'immagine, ma le increspature mostrano le posizioni delle onde d'urto che si sono allontanate dalla pulsar e hanno colpito il gas circostante.

Image caption: 在距地球约6500光年、位于金牛座的蟹状星云中心，存在着蟹状星云脉冲星。它是一颗大质量恒星生命终结时爆发后留下的残骸。虽然恒星爆炸发生于数千年前，但这次爆发产生的光芒直到公元1054年才抵达地球。这次天体事件曾被全球多地民众观测到，许多文明都在其历史文献中留下了相关记录。
蟹状星云脉冲星每秒约旋转30周，并发射包括可见光在内的多波段光线。其质量约为太阳的1.5倍，但在它形成时的爆发产生了庞大力量，将如此巨大的质量压缩在半径仅约十公里的极小的空间内。
这张图像由美国夏威夷双子北座天文台的多张观测图像合成而成，脉冲星清晰可见于画面中央。构建图像的观测数据采集时间跨度达五年，其中2009年的数据以蓝色标示，2014年的数据以红色标示。在此期间，抛射物质持续远离脉冲星，形成了图中的彩色涟漪效果。需要说明的是，颜色并非真实色调，波纹显示的是冲击波远离脉冲星并撞击到周围气体时的位置。

Image caption: 在距地球約6500光年、位於金牛座的蟹狀星雲中心，存在著蟹狀星雲脈衝星。它是一顆大質量恆星生命終結時爆發後留下的殘骸。雖然恆星爆炸發生於數千年前，但這次爆發產生的光芒直到公元1054年才抵達地球。這次天體事件曾被全球多地民眾觀測到，許多文明都在其歷史文獻中留下了相關記錄。
蟹狀星雲脈衝星每秒約旋轉30周，並發射包括可見光在內的多波段光線。其質量約為太陽的1.5倍，但在它形成時的爆發產生了龐大力量，將如此巨大的質量壓縮在半徑僅約十公裡的極小的空間內。
這張圖像由美國夏威夷雙子北座天文臺的多張觀測圖像合成而成，脈衝星清晰可見於畫面中央。構建圖像的觀測數據採集時間跨度達五年，其中2009年的數據以藍色標示，2014年的數據以紅色標示。在此期間，拋射物質持續遠離脈衝星，形成了圖中的彩色漣漪效果。需要說明的是，顏色並非真實色調，波紋顯示的是沖擊波遠離脈衝星並撞擊到周圍氣體時的位置。
