article_snippet.sent: Scientists announced today that measurements made by the European space probe Philae, which landed on comet 67P in November, show the comet's core isn't magnetised.
article_snippet.sent: A composite of 18 images showing off the comet 67P/Churyumov-Gerasimenko activity from different angles as seen between 31 January (top left) and 25 March (bottom right), when the spacecraft was at distances of about 30 to 100 km from the comet .
article_snippet.sent: If comet 67P/Churyumov-Gerasimenko is representative of all cometary nuclei, then we suggest that magnetic forces are unlikely to have played a role in the accumulation of planetary building blocks greater than one meter (3 feet) in size.'
article_snippet.sent: data collected by the Rosetta Plasma Consortium fluxgate magnetometer on board the orbiter (top) and the Rosetta Lander Magnetometer and Plasma Monitor on board the lander (bottom) have been used to investigate the magnetic properties of Comet 67P/Churyumov-Gerasimenko .
article_snippet.sent: Studying the magnetic properties of Comet 67P/Churyumov-Gerasimenko can provide clues to the role that magnetic fields played in the formation of Solar System bodies almost 4.6 billion years ago.
highlights_snippet.sent: Rosetta results do not support theory as 67P's core is not magnetised .
