Aliens are watching us from Phobos.

Phobos, one of the Mars moon, rotates Mars almost 3 times a day. That could be a safe place for Aliens to watch us. They can monitor a place on earth three times a day.

Phobos is hypothesised to be hollow. [link to en.wikipedia.org]
Possibly it is an underground city.

Russia has attempted to land a rover there, but failed. Phobos-2 failure is still a mystery. If you believe in conspiracies you have look at here.

"The last transmission from Phobos 2 was a photograph of a gigantic cylindrical spaceship - a huge, approx, 20km long, 1.5km diameter cigar-shaped 'mother ship', that was photographed on 25 March 1989 hanging or parked next to the Martian moon Phobos by the Soviet unmanned probe Phobos 2.

After that last frame was radio-transmitted back to Earth, the probe mysteriously disappeared; according to the Russians it was destroyed - possibly knocked out with an energy pulse beam."
