Rosetta Spacecraft’s comet, called the rubber ducky, is passing through changes in space. The comet is changing its colors as it’s moving, starting from red to blue, and then red again. The scientists are saying that the changes of color on the comet is happening because of the water cycle. The comet is the first one visited by humans with a probe.
The comet’s name is 67P/Churyumov-Gerasimenko, which is analyzed by scientists for many years, has complete study in the journal Nature. What is happening with the comet right now is an exciting process. 67P is passing through the boundaries of its orbit around the Sun, and the changes are in steps.
First, the comet crosses the frost line, and all the ice is turning to gas on the surface. Then the comet is covered in an outer layer of dust, having the red color. When the powder is blown away in space, the color on its icy surface is blue.
Comet 67P changed color, as noticed by the ESA Rosetta mission
What is happening with the comet is not something new. All of this started way back in January 2015 until August 2016. The scientists researched this phenomenon when the European Space Agency sent Rosetta on the comet.
The probe arrived on 67P on August 6, 2014, and the study began at once until September 30, 2016. The process we explained above is practically happening in two phases. The first one is the red phase when the comet is getting closer to the Sun. And the second one is the blue phase when the comet is moving away from the Sun.
In a word, Rosetta spacecraft provided a camera on the comet to record any changes in the color-sensitive perspective. These kinds of changes are not visible from Earth, so the landing of the probe was essential. Rosetta is no longer on the comet, but the scientists won’t stop with the studies.
