Google手機 - Android Kitkat

Android is the operating system that powers over 1 billion smartphones and tablets. Since these devices make our lives so sweet (the vender says), each Android version is named after a dessert: Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, and Jelly Bean. And now, Kitkat.

Happy Halloween - 'Witch Head' Brews Baby Stars 快樂萬聖節 - 女巫頭星群嬰兒恆星

'Witch Head' Brews Baby Stars

A witch appears to be screaming out into space in this new image from NASA's Wide-Field Infrared Survey Explorer, or WISE. The infrared portrait shows the Witch Head nebula, named after its resemblance to the profile of a wicked witch. Astronomers say the billowy clouds of the nebula, where baby stars are brewing, are being lit up by massive stars. Dust in the cloud is being hit with starlight, causing it to glow with infrared light, which was picked up by WISE's detectors.
The Witch Head nebula is estimated to be hundreds of light-years away in the Orion constellation, just off the famous hunter's knee.

WISE was recently "awakened" to hunt for asteroids in a program called NEOWISE. The reactivation came after the spacecraft was put into hibernation in 2011, when it completed two full scans of the sky, as planned.

一個巫婆出現尖叫在這個新的形象進入太空的美國宇航局的寬視野紅外巡天探測器，或明智。紅外線畫像顯示的女巫頭星雲，它的相似而得名一個壞巫婆的檔案。天文學家說，洶湧的雲彩星雲，嬰兒恆星正在醞釀，由大質量恆星被點燃了。星光在雲中的塵埃被擊中，使其煥發出紅外光，WISE探測器被拾起。

女巫頭星雲的估計是幾百光年遠的獵戶星座，只是關閉了著名的獵人的膝蓋。

智最近被“驚醒”追捕小行星名為NEOWISE程序。激活來到飛船後進入休眠狀態，按計劃在2011年，當它完成了兩個完整的天空掃描，。
