Comet 67P/Churyumov–Gerasimenko is Non-magnetic
Comet 67P/Churyumov-Gerasimenko, which is originally from the Kuiper belt, has been a subject of study for scientists for the past many years. Now, according to reports, scientists have found that the comet is non-magnetic, whereas the moon and meteorites have a strong magnetic field.
European Space Agency's Philae landed on the comet in November 2014. It was the first man-made object that successfully landed on a comet. The probe was launched by the space agency to trace origins of life on earth.
As per some reports, the comet, which orbits the sun at unprecedented speed, holds the secret on how the solar system was formed more than 4 billion years ago. The first results from the Philae lander did not reveal that the comet is non-magnetic. Scientists came to know about that through magnetometers, which were used to measure magnetism of the comet.
Imperial College London has been involved in the Plasma Consortium of instruments on the Rosetta spacecraft. The university has provided measurements in support of the lander magnetometer. According to Chris Carr from the department of physics, "There may be some minerals in the body of the comet that are magnetized, creating detectable signals on scales smaller than we can measure, but the results show there is no regular magnetic field on a meter-scale".
Carr said that the new results are surprising as moon rock samples and meteorites showed more magnetism than the comet. It suggested that the comet is non-magnetic, as per Carr. Carr further stated that it was the first experimental data from the device present on the comet.
Scientists could not find more about the comet as Philae shut down after it lost all its power. According to reports, Philae landed on the darker side of the comet, which means that it could not charge itself with solar power.
