Symphony Of The Fog – an ongoing celebration of the fogs of San Francisco by photographer Michael Shainblum, who sez of it:

The Fog in the bay area feels like it has a mind of its own. The fog can often times disturb a beautiful sunny day and cover the sky with darkness. There are mixed feelings about the fog, many residents finding it a huge inconvenience and depressing. Where as many residences embrace the fog and its erratic behavior.

A wise man once said something like ‘There is life on other planets, only not to see’.

It might have been Aidan Walsh. And how right he was.

It’s all down to the blinding glow of stars, which obliterates the ability of distant viewers to see the planets orbiting them.

In this TED talk, Princeton University astronomer Jeremy Kasdin explains a new  technology which may change all that: the Starshade – a flower petal-shaped screen that allows a telescope (located up to 50,000km from said Starshade) to photograph previously invisible planets trillions of kilometers away.
