tracking hubble
Fri, 16 May 2008 18:52:58 +0100
Hi. A group of us are building a sattelite tracking gizmo for a radio
amateur project and someone in the group. (Me) suggested it would arouse
interest if it we could use it to track hubble. We've got the downlink
frequency of hubble but we don't know what the doppler shift is or what
format theinformation dow ...

That thread about the Earth stopping spinning got me thinking:
Thu, 15 May 2008 17:32:05 +0100
Could the Earth become tidally locked with the Sun (hypothetically; say
the Sun has increased in size to allow it), or would the presence of the
Moon prevent it from happening?

The Sun's lower limb enters Orion, by IAU criterion, as every year.
Since all planets enter Orion (e.g. Moon in Orion both for Osama and
the WTC) , this event is nothing spectacular in an amused onlooker, or
at least at first glance so. Last year we had an exceptionally
prolonged "Lady Di" Mercury in Orion. The Le ...

What would happen if the earth stopped spinning?
Tue, 13 May 2008 18:08:46 -0700
Hi:
The 1st and obvious answer is that half the world would be night and the
other half would be day without change.
However, what would be the less apparent effects? For example, how would
it affect the ecosystem, the climate, polar ice caps.
Lets assume that the Earth stops spinning in a manner such tha ...

BBC - Virtual telescope opens night sky

Twirling galaxies, exotic nebulae and exploding stars are now just a
mouse click away for amateur astronomers.
Microsoft has launched WorldWide Telescope, a free tool that stitches
together images from some of the best ground- and space-based
telescopes.
Collections include pictures from the Hubble and Spitzer ...

Volunteers asked to help find dead spacecraft on Mars
Mon, 12 May 2008 14:17:33 -0700 (PDT)
Scientists have invited the public to trawl high-resolution images for
signs of NASA's Mars Polar Lander, which went silent on arrival at
Mars in 1999. Finding the wreckage might explain why the mission
failed.
"If we can find the Mars Polar Lander and be convinced we understand
what we're looking at, it might ...

Astronomy and music
Sun, 11 May 2008 09:44:32 -0700 (PDT)
I have written often of the common ground between musical creativity
and astronomical thinking -
"I carry my thoughts about with me for a long time... before writing
them down... once I have grasped a theme. I shall not forget it even
years later. I change many things, discard others, and try again and
again un ...
