Why Don't We See Meteors Hitting Jupiter?

When we look at Jupiter through a telescope, the planet's disc seems quite calm and serene. We don't see any bright trails of light around it, caused by meteorites entering the planet's atmosphere and burning up.

I wonder why. After all, Jupiter is a huge planet, with a mass hundreds of times that of the Earth. That mass must draw meteroids towards it like a magnet! And Jupiter has a huge atmospheric envelope. This provides ...

Craters of Mars

Hi All
I spent a couple of hours looking at Google Mars, and noticed that every crater I found was pretty much a perfect circle, with a cone in the middle, and a reasonably circular ejecta feature surrounding them. I'm pretty sure this would indicate a 90 degree strike, a shallower angle should be more teardrop shaped? Can anybody tell me why there are so few angular strikes.

Vampires

We know that vampires are sensitive to sunlight but I wondered which wavelengths they were sensitive to. Would a vampire be able to view the Sun through a hydrogen alpha or calcium K filter without harm?

Indeed, would a full aperture solar filter reduce sunlight enough to make viewing safe for vampires.

Do artificial daylight bulbs repel vampires or do we still need garlic?

time tunnel time tunnel

When we gaze out with our telescopes we are looking back in time but for us in real time. So why is that if we look the other way we can not see the future of where our galaxy is heading? We are in the future of the young galaxies we look back on so why not the galaxies far ahead of us? Or are we already seeing this distant future but got our results ...

Southern Hemisphere Viewing

I am considering a southern hemisphere hol. next year 2013 and have been finding out about New Zealand and Cape Verde Islands (15deg N.)
Should I take the NZ option or will I get a sufficiently good view from C V Islands?

Sorry for the quite eccentric query. :oops:
