去不了外太空，還能拍出置身于太空美景的自拍照？這不是夢，而是美國宇航局新推出的太空自拍APP，讓普通人也能過一把宇航員的癮。

Let's face it. Most of us are never going to go to space. And none of us are going to visit the Orion Nebula. But we can dream - and now thanks to NASA, we can selfie our way into some of the most spectacular scenery in the Milky Way.

面對現實吧。我們大多數人永遠不可能去太空，也不可能去獵戶座星云一游。但我們可以做去太空的夢——如今，拜美國宇航局所賜，我們可以通過自拍，置身于銀河最壯觀的一些景色中。

To celebrate the 15th anniversary of the launch of the Spitzer Space Telescope, NASA has released a delightful NASA Selfies app for iOS and Android phones.

為了慶祝斯皮策太空望遠鏡發射15周年，美國宇航局發布了一款好玩的太空自拍APP，適用于蘋果和安卓手機。

It's very simple. You snap a pic of your face (or someone else's face) centred in the frame, using the front or rear camera, and it's inserted into the helmet of an astronaut suit.

這款APP操作起來十分簡單。你只需用手機的前置或后置攝像頭拍一張自己或他人的大頭照，然后你的頭像就會被嵌入航天服的頭盔當中。

You can then choose a background of some of the many space wonders imaged by Spitzer over the last 15 years, and save it to your phone.

斯皮策太空望遠鏡在過去15年間拍攝了眾多太空奇觀，你可以從若干張太空奇觀圖片中選一張作為背景，然后保存到自己的手機里。

You can't upload previous photos from your photo gallery, and there's no share button, so you'll have to share your photos to the #NASASelfie hashtag the good old-fashioned way - by going to your camera roll and sharing from there.

你不能從自己的圖片庫中上傳先前的照片，而且沒有分享按鈕，所以你必須用傳統方法將照片分享到#美國宇航局自拍這個話題標簽下，也就是從手機相冊中選取照片分享。

Also, just a heads up, it only orients correctly in landscape, so if you take a photo holding your phone in portrait orientation, you're going to end up looking like a severed head floating in a spacesuit.

另外，再提醒一句，你的頭像照片只有在風光模式下拍攝才能準確嵌入航天服，所以如果你是在人像模式下拍攝，你的頭像可能會“浮”在航天服上。

現在就可以免費下載應用NASA Selfies，成為一名“宇航員”：
