A series of photos taken over an hour long period show the full moon as it is shadowed by the Earth as a total lunar eclipse marks the arrival of the winter solstice Tuesday, December 21, 2010
Skygazers with a clear view in North America and Europe were greeted with a celestial treat early Tuesday, as a unique total lunar eclipse turned the Moon pink, coppery or even a blood red.

Coinciding eerily with the northern hemisphere's mid-winter solstice -- for the first time in almost four centuries -- the eclipse showed the Sun, the Earth and its satellite as they directly aligned, with the Moon swinging into the cone of shadow cast by its mother planet.
Despite being in shadow, the Moon did not become invisible, as there was still residual light deflected towards it by our atmosphere.
Most of this refracted light is in the red part of the spectrum and as a result the Moon, seen from Earth, turned a reddish, coppery or orange hue, sometimes even brownish.

Buruj mudahkan pengenalan bintang di langit

Terdapat 88 sistem buruj di langit. Buruj sebenarnya adalah titik-titik bintang yang dikumpul dan dibahagikan serta diberikan nama-nama tertentu berdasarkan bentuk supaya mudah diingat. Ini merupakan cara sistem buruj mula terbentuk. Justeru, buruj ini sebenarnya bukanlah satu perkara yang benar. Ia sebenar adalah lambang khayalan ahli-ahli syair, petani dan juga astronomi lebih 6,000 tahun lalu. Tujuan sebenar penciptaan buruj ini adalah bagi membantu kita mengenal pasti jutaan bintang di langit. Semasa langit gelap, anda boleh melihat lebih kurang 1,000 hingga 1,500 bintang. Pasti sukar untuk kita mengenal pasti bintang yang mana satu. Malah sekali imbas, titik cahaya yang berkedipan di langit malam kelihatan sama sahaja. Oleh itu, beribu tahun dahulu, ahli astronomi awal telah membahagikan bintang mengikut kumpulan dan melukis gambar khayalan seperti kala jengking atau beruang, di sekeliling kumpulan bintang tersebut supaya mudah diingat. Bintang di dalam sesuatu buruj itu se

Why Do Languages Die?

Urbanization, the state and the rise of nationalism. “The history of the world’s languages is largely a story of loss and decline. At around 8000 BC, linguists estimate that upwards of 20,000 languages may have been in existence. Today the number stands at 6,909 and is declining rapidly. By 2100, it is quite realistic to expect that half of these languages will be gone, their last speakers dead, their words perhaps recorded in a dusty archive somewhere, but more likely undocumented entirely. (…) The problem with globalization in the latter sense is that it is the result, not a cause, of language decline. (…) It is only when the state adopts a trade language as official and, in a fit of linguistic nationalism, foists it upon its citizens, that trade languages become “killer languages.” (…)
