Researchers involved in the Deep Impact mission collected data from the July 04 collision with comet Tempel 1 and found surprising results. For example, the heart of the comet nucleus has a very soft which is lower than snowbank powder. The fine dust of the comet is bound by gravity. However, the gravity is so low that you would be projected in space if you keep on this white and you jump.

Another surprise comes from what appears to be impact craters on the surface of the comet. Previously, the nuclei of two other comets have been

One of the most interesting discoveries may be the huge increase in carbon-containing molecules detected in spectral analysis of the ejection plume. This finding indicates comets contain a substantial quantity of organic matter, and may thus have brought such material to Earth early in the planet's history when the asteroids and meteors hitting us more frequently.

Another discovery is that the comet interior is well protected from the sun warming caused by the surface of the comet nucleus. Mission data indicate that the nucleus of Tempel 1 is extremely porous. Its porosity allows the surface of the core to warm up and cool down almost immediately in response to sunlight. This suggests that the heat is not easily conducted to the interior and ice and other materials embedded inside the core can be primitive and unchanged since the early days of the solar system, as scientists had suggested.

Notes-

The Russian cargo spacecraft (unmanned) Progress 18 was detached from the Zvezda module of the International Space Station (ISS) today at 10:26 GMT. Filled with waste, it burned in the Earth's atmosphere over the Pacific Ocean, around 14:00 GMT.

His successor, Progress 19, will take off from Baikonur tomorrow at 13h08 GMT. It will bring to the ISS (which dock to the 10/09 at 14:50 GMT) for food, fuel, etc.
