Have you ever seen the Andromeda galaxy? Although M31 appears as a faint and fuzzy blob to the unaided eye, the light you see will be over two million years old, making it likely the oldest light you ever will see directly. Now rising near a few hours after sunset from mid-latitude northern locations, Andromeda is rising earlier each night and will be visible to northerners all night long starting in September. The featured image captured Andromeda rising above the Italian Alps last month. As cool as it may be to see this neighboring galaxy to our Milky Way with your own eyes, long duration camera exposures can pick up many faint and breathtaking details. Recent data indicates that our Milky Way Galaxy will collide and coalesce with the slightly larger Andromeda galaxy in a few billion years. Follow APOD on: Facebook, Google Plus, or Twitter

你有冇睇過安德羅梅達銀河？雖然M31對肉眼來講只係一個微暗模糊嘅斑塊，但你所見到嘅光輻射已經超過兩百萬年，使得呢個可能係你一生中能夠直接看到嘅最古老光線。喺中緯度嘅北部地區，安德羅梅達銀河由日落幾小時後開始升起，並且會隨住夜晚越來越早升起，直至九月開始會全天候被北方居民觀賞。呢幅featured image係上個月安德羅梅達升起時喺意大利阿爾卑斯山所拍攝。能夠親眼睇到呢個與我們的銀河系相鄰嘅銀河雖然幾酷，但長時間的攝影曝光可以捕捉到無數微弱而驚豔的細節。最近嘅數據顯示，我們的銀河系會在幾十億年之後與稍大嘅安德羅梅達銀河碰撞並合併。
