Let's hope no aliens tried to contact us in the last four months. If they did they might have heard a busy signal, because the SETI (Search for Extra Terrestrial Intelligence) project, which uses a field of satellite dishes to search for non-human life forms, has been offline since April. The project was shuddered due to a lack of funds, but now thanks to friends of SETI, it will be back up and running next month.

Of course, any life trying to get here will have to get through our massive layer of space junk. It's thick and getting thicker. We're humans and we ruin everything. Scientists are trying to figure out how to best deal with all the junk orbiting the Earth.

Also: there's evidence of flowing water on Mars.
