According to a report by BBC, the ESA or the European Space Agency has released breathtaking and detailed images of the Comet 67P/Churyumov-Gerasimenko.ESA probe has sent images of the comet in great detail that with proper software and a 3D printer, one make a model of the comet.
Rosetta spacecraft is orbiting the comet and for the first time in the history of mankind will send a probe on the comet to study its structure.
The images has for the first time provided the actual dimensions of the comet. Earlier estimates had described the comet to have a dimension of 4 km. The latest images reveal that the comet is 2.5 km by 2.5 km by 2.0 km by its head, the smaller of the comet’s two lobes, and 4.1 km by 3.2 km by 1.3 km by its body, the bigger lobe. Earlier estimates had put the mass of the comet as 10 billion tons and a density of 400 kg per cubic meter. The surface temperature of the comet is in between -68 degrees centigrade and -43 degree centigrade while the sub surface temperature is in between -243 degrees centigrade and -113 degree centigrade. Rosetta has discovered water, carbon monoxide, carbon dioxide, ammonia, methane, and methanol, all in gaseous form, on the comet.
Scientists are eagerly waiting for Rosetta to send more detailed images of the comet with its OSIRIS camera.
The comet 67P is at a distance of 464 million km from Earth. The comet is hurtling towards the Sun and the next mission of Rosetta is the deployment of the lander Philae as the comet moves deeper into the solar system. Philae will separate from Rosetta on November 12 if everything goes right. It will be a tricky maneuver which will last for seven hours.
