Comet 67P approaches closest point to Sun
According to reports, Comet 67P is approaching the nearest point to the Sun. As per experts, on Thursday, "perihelion" will take place at 03:03 BST. During this time, 67P will be approximately 186 million km from the Sun.
The icy world is being explored by the Rosetta team. Dust and gas were released from it, together with a dazzling jet observed on 29 July. On Tuesday, spectacular images of this event were released by the European Space Agency, ESA. So far, the brightest jet has been observed by Rosetta's cameras.
According to Carsten Guettler, a member of the Osiris camera team from the Max Planck Institute for Solar System Research in Germany, "Usually, the jets are quite faint compared to the nucleus and we need to stretch the contrast of the images to make them visible - but this one is brighter than the nucleus".
As a result of such material released by comets, they have their characteristic tails during their appearance in the night sky. The material is released as they approach the Sun more actively. This jet that is a result of frozen ices converting to gas, was brief and bright. Three images that are separated by a few minutes, capture it emerging and fading.
It is not expected that this kind of activity inevitably coincides with perihelion, for the reason that any temperature increase is slow - and also falls behind actual distance of the comet from the Sun.
