Using Satellites to check the cloud cover
So how do you check for cloud cover using an IR Satellite image? Turns out there are many satellites beaming information back to earth which is accessible via the internet. A great use for these images is to check the viewing conditions for viewing the stars. I've done a few searches and came up a website which stays reasonably up to [...]

Life after Hubble?
I recently blogged that the absense of Hubble would leave a huge gap in astrophography which didn't seem likely to be filled anytime soon.

It is the [...]

Water Water everywhere….
It doesn't rain but it pours! Certainly thats what it feels like when within just a short few hours you start to hear about water on the moon (yes the moon!) and now on Mars. Given the fact that water may be more abundant than previously thought it is reasonable to deduce that we can use this information to help us decide possible future [...]
