Fenomena luar biasa di langit...


Jika berkesempatan, renunglah ke langit sekarang. Sayangnya saya tiada kamera canggih untuk merakamkannya (astrophoto)...

Inilah kali pertama saya melihat bulan sabit muncul diringi dengan dua bintang secara selari pada kedudukan di utara bulan sabit tersebut.
Bagai tersenyum memandang kita di atas bumi ini...

The "Venus & Jupiter" Show

Over the next few days, anyone looking southwest after the Sun sets and evening twilight deepens will witness a close pairing of the two brightest planets, Venus and Jupiter. On November 30th and December 1st they’ll be separated by only 2° — about the width of your finger held at arm’s length.

And on the evening of December 1st, skywatchers in the Americas will see the crescent Moon joining the two planets to make a remarkably compact celestial triangle. It’s sure to turn heads.

The accompanying illustration shows the scene. It's plotted for observers in the middle of North America (and the alignment of the Venus-Jupiter pairing is exact for November 30th), but it’s close enough to give a good idea of how the scene will look from anywhere in North America on the evenings in question.

Although the three objects look close together, the appearance is deceiving. The Moon is only 252,000 miles away, less far than you may have driven a car in your lifetime. Right now Venus is 370 times farther away, at 94 million miles. And Jupiter, at 540 million miles, is nearly six times farther than Venus.

If the sky is cloudy for this event, don't despair. Venus and the crescent Moon will have another spectacular twilight pairing (though without Jupiter) on December 31st, New Year's Eve!

This marks the second time this year that Venus and Jupiter have mimicked a brilliant "double star" in our sky. Back on February 1st, they appeared together in the eastern sky before dawn. At that time they nestled even closer together — only ½° apart.

The last time these two planets were paired in the evening sky and easily seen was September 2005, when they appeared about 1½° apart. They won't be this close together and well placed for evening viewing again until May 2013 (1° apart).

Speaking of "tiada kamera canggih," I met up with your husband at his office yesterday. It was like a Museum of Cameras.

Thanks for the compliment...:) just that during that time all the cameras were not at home.
