Sometimes I complain about the earthly weather, but mostly I like to post about astronomy and space events. Hope you enjoy the articles.

TREMBLING EARTH, WOBBLY STARS: In Chile, astronomers know the ground is still shaking. They can see it in the stars. Colin Legg reports from the Andes east of Santiago: "I made this 88-second exposure on Sunday night, Feb. 28th, less than 24 hours after the big 8.8-magnitude quake. It records the movement of the Earth in the star trails during an earth tremor."
Earthquake experts say the shaking will continue for months. Indeed, in the days after the "Big One", Chilean seismometers have recorded more than 10 aftershocks in the range 6th to 7th magnitude, and more than 200 aftershocks stronger than 4th magnitude. A tip for astrophotographers: Keep your exposure times short. The stars over Chile could be wobbling for some time to come.
