Esa's Rosetta mission is currently making its way towards a comet in the solar system.
And, in a series of stunning new images, it reveals how comet 67P/Churyumov-Gerasimenko has begun to develop into an exciting ball of dust and gas.
Over a period of six weeks the comet has begun to extend its dusty veil known as a 'coma' into space.
Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, this glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and complex dust sculptures dominate this detailed skyscape taken in infrared light by NASA's Wide Field Infrared Survey Explorer (WISE) satellite.
