Re: Spaceships and astronomy
So has anyone succeeded in seeing the planet cluster, including Mercury? It has been too cloudy near me most days recently, and in any case there are too many trees in the immediate vicinity of Pulaski manor to get a good view of the horizon. :(

Re: Spaceships and astronomy
I stayed on the US Lexington with the Boy Scouts recently and as part of the trip they showed us an IMAX movie about the space station and future exploration/travel to Mars. The next generation of interplanetary vehicles look awesome and it was super interesting.

An exciting development in the area of applied astro-physics.

Good BBC videos. It seems to be a massive breakthrough in science. I also find it amazing that Einstein, living almost a century ago in relative technological pre-history, was able to accurately theorise so much of this stuff.

It's a remarkable discovery. The vindication of Einsteins work is fantastic.

Now that they've found these gravity waves, I wonder what they can do with them. I don't see any obvious way to focus them to make any sort of image. :unsure:

Here's and odd story, apparently "something" hit Jupiter. :unsure:

Not quite Schumaker-Levy 9, but yeah Jupiter most likely gets hit with debris and asteroids quite often due to its enormous gravitational field. Really, the fact that we aren't getting hit by large objects more often is most likely because Jupiter deals with them before they reach the inner solar system. We're very lucky Jupiter is there in the first place :D |

But yeah, the gas giants are the silent protectors of the inner solar system. |

Yes. And apparently Uranus takes quite a pounding, too ...
But yeah, the gas giants are the silent protectors of the inner solar system. There was also likely a fifth gas giant. I first heard about it a couple of years ago, but it is an interesting theory, that some where "out there", there is a fifth gas giant planet that was flung out of the solar system. I seem to recall seeing an estimate of how far it could have reached after four billion years at a speed markedly slower than the speed of light. |

Re: Spaceships and astronomy
Maybe we/intelligent life, can't evolve without a big-ass junk collecting planet in the system, which makes the discovery of super-Jupiters in other star systems very encouraging.
Also, continuing my M42 fixation http://apod.nasa.gov/apod/imag/1603/...jedor_2263.jpg OK, its a stackup of many frames, but its gorgeous. |
