What’s that looming behind this gravel-strewn hill on Comet Churyumov�Gerasimenko? A jagged cliff. The unusual double-lobed nucleus of Comet 67P/Churyumov�Gerasimenko lends itself to unusual and dramatic vistas, another of which has been captured by the Rosetta spacecraft that arrived at the comet last September. The featured cometscape, taken last October and digitally enhanced, spans about 850 meters across. Meanwhile, Comet Churyumov�Gerasimenko continues to sprout jets as it nears its closest approach to the Sun in August. Along the way, Rosetta will continue listening for signals from Philae, a probe that landed on the nucleus but rebounded to an unknown surface location last November. If newly exposed to sunlight, Philae might regain enough energy to again signal Rosetta. Click Through the Universe: Random APOD Generator

在Churyumov-Gerasimenko彗星的這座石礫小丘後面，隱藏著什麼呢？是一道 jagged cliff（尖銳懸崖）。這顆67P/Churyumov-Gerasimenko的雙葉核結構，造就了獨特而戲劇性的景觀，這些景觀中的一個已由羅塞塔探測器（Rosetta spacecraft）捕捉到。這幅作品於去年十月拍攝並經過數位增強，橫跨約850米。隨著 Churyumov-Gerasimenko 彗星接近八月最近的太陽位置，彗星上不斷噴發出噴流。羅塞塔探測器將繼續向費拉（Philae）探測器發送信號，費拉去年十一月在核上著陸後彈回至未知的表面位置。如果費拉重新暴露於陽光下，它可能會再次獲得足夠的能量來向羅塞塔發送信號。
