Glossary term: 恆星殘骸
Description: 恆星殘骸是白矮星、中子星和恆星質量黑洞的統稱。它們代表了恆星在完成主序階段的氫燃燒並經歷巨星階段後，演化至最終階段的狀態。與恆星相比，恆星殘骸非常緊密。白矮星（恆星殘骸中體積最大的類型）通常將約一個太陽質量的物質壓縮到地球大小的空間中。恆星殘骸的核心不再通過核聚變產生熱量。在密近雙星系統中，恆星殘骸可能成為新星、Ia型超新星的來源，或者（如果兩個恆星殘骸相互旋近並碰撞）會產生引力波爆發。

大質量恆星的死亡
Caption: 用地球上和太空中的望遠鏡拍攝到的鄰近小麥哲倫雲星系中一顆中子星的多波段圖像。中子星（在這裡被看作是被紅色環包圍的藍色斑點）是大質量恆星引力坍縮、壓縮和爆炸的最終產物，被嵌入其超新星殘餘物（綠色）中。

Remnant of SN 1006
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.

蟹狀星雲脈衝星
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。
