Scientists studying the Comet 67P say they may have found evidence of how the object first formed. The icybody is currently moving through space, some 500 million kilometers from earth. And it’s been tracked by Europe’s Rosetta Satellite.

The probe is sending back a constant stream of photographs. And it’s in someof these pictures that researchers have identified what they’re calling the comet’s 'goosebumps'. It’s possible they may be the original blocks of material that came together more than 4.5 billion years ago tomake 67P. Here is our science correspondent Jonathan Amos.

The researchers working on the Rosetta Mission have just published a series of reports in Science magazinein which they make a first attempt to characterize the comet that looks so much like a rubber duck in space.The team details its many strange behaviors. There are winds that rush across its surface.

In other places, huge blocks, the size of football fields are lifted by explosive gas and then dumped. Some locations feature deep pits and depressions where the surface appears to be collapsing in on itself. But the key finding may be the “duck’s” goosebumps, extensive areas of lumps and bumps all about three meters in size.

Scientists speculate that these are the primitive icy blocks that clumped together in the very early days of the solar system to build the comet we see today. If that’s true, it’s a startling discovery. Sir Steven Larry.

Absolutely. Remember these objects formed at least 4.5 billion years ago. So it is very exciting.

The Rosetta probe will continue to follow the four-kilometer wide comet as it moves closer to the sun thisyear.

Egypt’s Ministry of Antiquities is investigating how a visible layer of adhesive wound up on the beard ofthe famous golden Tutankhamen burial mask. One media report claims that it was hastily glued back on the mask last year after it had been loosened or even knocked off. Our correspondent has been to see the mask at the Egyptian Museum in Cairo and she sent this report.

The burial mask or King Tutankhamen has survived for over three thousand years. At the museum today, we saw a glue-like substance along the join between his blue and gold beard and the rest of the mask. The two pieces were made separately and have always been fixed together. The museum’s director told us a mistake could have been made during regular maintenance.

I know that this is a very precious and very important piece.
