Scientists tracking and recording the movements of Europe's first comet to land on a comet, Philae of the shipment Rosetta announced today that the comet of the project has no magnetic field! 
The news is of course the comet, 67P / Churyumov-Gerasimenko, and can provide some basic information about the formation of celestial bodies such as comets and planets - in the early stages of their development.
Ο Philae is one device σε μέγεθος πλυντηρίου που αποσυνδέθηκε από το μητρικό σκάφος Rosetta και προσεδαφίστηκε στον κομήτη. Από τότε συλλέγει δεδομένα (από τον περασμένο Νοέμβριο). Οι επιστήμονες λοιπόν μελετώντας αυτά τα δεδομένα διαπίστωσαν ότι η επιφάνεια δεν είναι μαγνητισμένη, όπως αναφέρεται σε μια έκθεση της Ευρωπαϊκής Υπηρεσίας Διαστήματος (ESA), first published by Science magazine and presented at the European Geosciences Union in Vienna.
Let's remind that the landing of the detector was not smooth, and it took four attempts (three bounces) to reach the current landing area. The complexity of the landing helped the team discover that the comet did not have a magnetized core.
But the understanding of this "detail" came later when the team was able to compare measurements from different points of contact along the comet's surface.
Matthew Taylor, ESA's Rosetta project scientist reported in Nature. "That Comet Churyumov-Gerasimenko has no magnetic field could help us solve its puzzle creationof the planets and how it evolved from the proto-planetary disk.”
Philae is currently in hibernation to maintain the battery, but can be rebooted from the end of May. This means that communication could be restored perhaps by the end of June.
