Rosetta spacecraft send back data on Wednesday which shows some massive sinkholes on Comet 67P.
NASA is amazed by the size of the sinkholes, which seem to be bigger than the pyramids of Egypt. They have substantial diameter and large dimensions.
Officials believe that an unknown object must have collapsed onto Comet67P for such massive holes to get created, but as to what the object could have been so far they are clueless.
The Comet 67P’s, also known as Churyumov-Gerasimenko, surface has been a reason for speculation since August. The Rosetta spacecraft has found cavaties, which are 656 feet wide (200 meters) in a diameter, plus 180 meters (590 feet) deep.
This discovery will open doors for scientists into researching how these comets are formed and how they evolve.
Officials are researching the comets physics to determine some factual possibilities.
Finding the massive pit was a total surprise says Paul Weissman from NASA’s Jet Propulsion Laboratory in California.
Comets like 67P are made up of stone, organics and ices; basically they are mini heaps of gravel.
They come and bind together because of gravity leaving a lot of clear spots. Why the pit area starts falling apart is still a mystery to scientist. One theory is that as the comet moves closer to the sun it warms up the comets ordeal, some of the sinkholes are moving out the jets of dust particles.
“We see jets rising from the cracked areas of the walls inside the pits,” says researcher, Jean-Baptiste Vincent and the Planck Institute for Solar System Research “These cracks mean that volatiles trapped under the surface that can be warmed more easily and subsequently escape into space.”
Rosetta has been researching these comets since the last 6and half years and its concluded that August is the time when the comet is closest to the Sun and when the pits are freshly formed holes.
There also seems to be an unnamed material developing and collecting in these pits.
