article_snippet.sent: It is hoped that continuing studies like this could reveal what the comet's interior is composed of - but engineers will be hoping that this 'false stars' anomaly does not occur again .
article_snippet.sent: the jets are formed when ice on the surface sublimates - or vapourises - and the jets become more active as the comet approaches the sun.
article_snippet.sent: But after making two unscheduled bounces on the surface, the probe landed in an unknown location and ran out of power.
highlights_snippet.sent: The problem occurred when flying just nine miles above comet 67P .
