馬頭星雲位於獵戶座,也稱為巴納德33(Barnard 33),在發射星雲IC 434之內,是一個暗星雲[1]。這個星雲就在獵戶腰帶最東邊的参宿一南方,並且是非常巨大的獵戶座分子雲團的一部分。馬頭星雲距離地球大約1,500光年,是最容易識別的星雲之一,因為從地球看過去,黑暗的塵埃和旋轉的氣體構成的形狀有如馬頭。這個星雲的形狀在1888年第一次被注意到,哈佛大學天文台的威廉敏娜·弗萊明在拍攝的B2312號乾版中發現了這個暗星雲。

增長的紅光主要來自星雲後面的氫氣,它們是被鄰近的亮星獵戶座σ電離產生的。黑暗的馬頭星雲主要是由濃厚的塵埃造成,而馬頭的頸部下方在左邊造成了陰影。離開星雲的氣體因為強大的磁場而形成漏斗狀,馬頭星雲基部的亮點都是正在形成過程的年輕恆星。

More than anything, this photograph was really the result of a series of little accidents. After abandoning a hike halfway through due to lack of sunlight, we subsequently began to make our way back home. As we drove through a long stretch of highway, I made the decision to nap in the back, but before that, for whatever reason, I peered out the window and into the heavens first. At that point, I began screaming like a madman telling everyone to look up. Amazed, we pulled into the next rest stop.

Marzipan pig

The marzipan pig is a traditional German and Scandinavian confectionery consisting of marzipan shaped as a pig.

During Jul in Norway, a tradition is to eat a rice porridge known as risgrøt; a single almond is hidden in the porridge. Whoever finds the almond receives a marzipan pig as a prize. The same tradition exists for Christmas Eve in Denmark, but with risalamande.

In Germany, marzipan pigs are given at New Year's for good luck (Glücksschwein).
