Now's a great time to break out that backyard telescope. Because Saturday, March 3, is the Mars opposition. It's one of the times that the Earth and Mars pass the closest to one another. The name—the Mars opposition—means that Mars and the sun are on, well, opposite sides of us. And it happens only once every two years and two months.
美好的時刻到來了，去把后院的望遠鏡打開吧。本周六也就是3月3日是火星沖日的時刻。這是地球和火星彼此距離最近的時刻之一。火星沖日是指火星和太陽正好運行到地球的兩側。這種天文現象每兩年零兩個月才發生一次。
But if you don't have such equipment handy, you might want to head over to the online Slooh Space Camera.
如果你手頭沒有觀測設備，你可能會想到Slooh Space Camera網站。
It's usually a members-only site that allows users to look at web images broadcast from telescopes around the world and to click to snap photos. The pictures get integrated into Google Earth/Sky. The site also offers free weekly space shows.
通常而言，它是一個僅限會員使用的網站，可以讓用戶看到世界各地的望遠鏡傳上來的圖片，會員還可以點擊Snap-photo照片。該網站上的圖片被整合到谷歌天空上。而且，該網站每周還提供免費的空間展示。
But Saturday there'll be a free live streaming of the Mars Opposition, hosted by astronomy experts. It'll include views of the planet from a variety of observatories including those in Arizona and the Canary Islands. You'll be able to pick out surface features such as canyons, volcanoes and polar caps.
星期六將有一個由天文專家主持的免費直播的火星沖日討論組。你將聽到來自包括亞利桑那州和加納利群島天文臺在內的各大天文臺的專家對火星的看法。你將可以分辨出火星的表面特征，如峽谷、火山和極地。
The online broadcast will begin on Saturday at 11 P.M. Eastern time. Head over to the online Slooh Space Camera.
