There is very famous quote: when you really desire something with your bottom of the soul, the entire world unites in helping you to get it. This is what happened in the early morning with the astronomer Maurizio Pajola. He was staring up for hours through pics taken by the spacecraft ‘Rosetta’, duck- shaped comet. This event took place around 3 a.m. as this is the only time he can work on this new mission. He had just started his new work, learning Mar’s moon Phobos at NASA’s Ames research center. He works on this only in the spare time.
As usual, in the midnight he was looking at a pics taken on December 2015. He found something interesting, a spot of bright and white shined out from the comet’s dim surface. Seeing this, he started flipping the past record of images taken by Rosetta’s until he reached July 4. He found a gash which was more 200 feet long and wide. A person can easily fall through in this gash.
Afterward, he gone through the next image, taken on July 10. In this image, he found a plume of gas and dust coming from the comet. After five days, OSIRIS got another view. The cliff face has distorted. This reveals that there is a radiant material underneath.
In a paper published in a `journal on Tuesday, Pajola and his co-worker revealed that the event they have spotted was a landslide. This event was the first thing, they have captured on comet’s surface.
The landslide was the most unusual of several geologic events that scientists have seen so far. They have also seen a lump of ice and rock of Mount Fuji’s size.
Further study suggests that these may be a sign of ice water on the comet’s surface.
A paper published in the journal Science, the scientist, has briefed the event of how the comet’s surface is regularly changing. This is due to its spin and the glare of the sun.
Reportedly, these images are revealing that comets are the most geologically active things. Scientists have reported various events like dust covering areas that don’t have dust particle before, cliffs collapsing, boulders rolling much more.
Pajola is a full-time researcher at NASA. He is working with Rosetta team since 2004 when the spacecraft was launched. After that, he is regularly studying the data from this in his spare time. He told that he love science and comets can be neglected as they are very important for us.
