Europe sees five possible sites for comet landing
Paris (AFP) Aug 25, 2014
The European Space Agency (ESA) on Monday said it had drawn up a shortlist of five possible sites for carrying out the first-ever landing on a comet. Astronomers have been scrutinising high-definition photos sent back by the Rosetta spacecraft, which rendezvoused with Comet 67P/Churyumov-Gerasimenko on August 6 after a 10-year chase through the Solar System. In mid-November, ESA intends to send down a robot laboratory, Philae, which will harpoon itself to the comet's surface and carry out a batt ... read more

Comet to pass Earth close enough for binoculars
For those of us who are interested in astronomy but don't have the equipment to really take a peer into space, there will be an interesting opportunity this week. A comet named "Comet Jacques" will be passing Earth close enough to be viewed by binoculars. The people at the Southern Observatory for Near Earth Astroids Research (SONEAR) in Brazil saw the comet months ago with their high tech equipment, but now you can see it with something many people only use for looking at birds. ... more
