Re: Colonise space or perish ..

In a recent TV interview, Stephen Hawking said that colonising space was the only hope for humanity's survival - faced with wars, population growth and ecological problems, etc. This is ludicrous, if not supercilious, advice from someone of Hawking's scientific stature. To abandon Earth's problems ...

Hi Northerner, Looks like it could be because it is an X-ray image . I think you are correct, Dave. There's detailed information for the image, on the Chandra web site, here . By clicking on the tabs "Composite" "X-ray" and "Optical" you can see that the point source i...

Cassiopeia A.

The Astronomy Picture of the Day website, today, shows an image of the supernova remnant Cassiopeia A and states that "the bright source near the centre is a neutron star the incredibly dense, collapsed remains of the stellar core". I am a bit surprised that this relatively small object wo...

I am still having a problem putting my own location into the latest version of Stellarium. I did not have a problem with an older version! Has anyone else had a problem doing this? I change the location but whenever I leave the website, and return, the location has reverted to that of Paris. If oth...

hello northerner, if i were you id uninstall it and download it and reinstall it again, :) I have already tried that but will try again. The fact that, after I have changed from Paris, the latitude/longitude figures remain the correct ones and only revert back to the Paris figures, after I leave an...

Change your location, as you have done and give it a name - it will appear in the list of possible locations. Select it and you will be in the right location then check the "use as default" button. I think you have to close and reopen Stellarium for this to "stick" - if that mak...

Stellarium.

I have a slight problem with Stellarium altho' this may have something to do with what I believe was a recent virus attack on my PC. This made it necessary to have a partial reinstall (I think that is the correct expression) of Windows XP. After this I downloaded the most recent version of Stellariu...

Can anyone explain?

Latitude/longitude figures.

I have a question not related directly to astronomy. Yesterday I was looking at latitude and longitude figures, for my home area, on Google Earth. I noticed there were 4 figures given. Also when I put my location into Stellarium recently there appeared to be spaces for 4 figures/ numbers again. I th...

Pheonix Lander

just finished looking at the image 15th.June 2008 at the "Astronomy picture of the Day" website. The photo shows the Phoenix Lander on the northern polar plains of Mars. Can anyone give a rough estimate of the distance, to the horizon, in this photograph? I know the figure would depend on ...
