Harry, the Andromeda galaxy is about 2x10^19 km away. At least, that's what my physics text book says. And it cost me 150 bucks, so it better be right! Yaarrr! :? The question is: is that the distance from our location in the Milky Way to the nearest part of Andromeda? Or is that the center of our g...

ckam: if you don't have one, a sky chart for your PC can help...you can filter the Messier/NGC objects that are displayed on your screen by apparent magnitude.

Re: Phobos as precurser for geysers?
Great explanation Pete, it makes total sense to me ! Do any Mars probes have seismic sensors for Marsquakes ? Is there much seismic activity on Mars? If I remember correctly kovil, I don't believe there is much seismic activity on Mars. The core of the planet is thought to have cooled enough for vo...

A gold brick in fact! But apparently the Cafe doesn't sell alcoholic beverages...especially anything with Arcturian Mega-Gin!

BMAONE23 - agreed. I am particularly interested in more research and experiments on possible materials for radiation shielding. One of the largest barriers to becoming a space faring species is radiation such as cosmic rays. Once we leave the protective magnetic field of the earth, we'll have to fin...

Ok Martin, here’s my response. I’ll run through each point. My argument was that the goal of sustainability on Earth is a more pressing and more urgent need than human expansion into space. Along those lines, robotic probes can collect a good amount of data for the cost when compared to human explor...

Many robotics missions are planned to take place before a manned mission. A trained geologist can observe and preform a basic analysis in 15 seconds for the same information the present robots are capable of in an hours time plus can maneuver data point to data points exponentially faster. Humans a...

Is it too small an area for an accurate spectral analysis? Why is water a reason to go to Mars? Is it that water makes it more likely that life exists? I think the (potential) discovery of life is a good reason to send unmanned missions until we have discovered enough that manned missions are produc...

Harry, if I may, it seems that there is a pattern to the theories you are drawn to. Infinite universe in something of a steady-state; time that is static regardless of the observer; gravity that is for all intents and purposes instantaneous... It sounds like you, like so many others over the years, ...

Or you can simply copy it before you try posting it -just in case your post time expires. being paranoid: what if the power goes off? Get a battery back up system. That will give you some time to save your data. Then maybe you should use a pen (scratch that) PENCIL and paper for the rough draft, eh...
