Starship Asterisk*

I would rather they parked it around Iapetus (sp) and do some really great mapping. Good post there Lucky. and a good question from Emery. :) Norval I suspect mission investigators will weigh all the evidence gathered and determine where would be the best place to park the craft for any continuing ...

When the Cassini mission finally ends, what is the fate of the spacecraft?

BET on it that if the forum has a "pseudoscience" section then they are going to be very closed minded to anything outside of the "box". Many forums have moderators and posters that "guide" the discussions into side tracked issues that don't even apply to the topic. My...

I could uncover forums using Google, but what I also seek are testimonials of which are good and which are bad. Moderated forums tend to be the best.

In the 3rd episode of the PBS Nova presentation of “The Elegant Universe", the following dialog ensues: Burt Ovrut (Univ. of Pennsylvania): It’s so simple. Here’s a brane on which we live, and here’s another brane floating in a higher dimension. There’s absolutely nothing difficult about imagin...

If anyone has a copy of Misner, Thorne and Wheeler I think it would solve the issue, If someone hasnt answered it by Monday I'll check the copy at work. Or ask the GR experts there. I, for one, would appreciate just that. If the forumula is applicable, I would like to know how it is derived, and ho...

That's interesting! I never thougth that Newtonian gravity would predict the curvature of light in a gravitational field. But apparently it does, just not to the degree that General Relativity does. The acceleration due to gravity from a massive body is equal to: a = Gm/r^2 Where does this formula ...

Used to be a time that the Asterisk CAFE forum was the place for any question ... but that has turned into a spammers paradise and has become unusable. That is most unfortunate. As a layman, I seek forums where I can pose and discuss serious questions I have about physics, astrophysics, and other s...

For physics questions and topics not appropriate for this forum, what other forums exist that would be appropriate?

How is it that Newton's laws of gravitational attraction can be applied to the bending of light? The following is an excerpt from Archives of the Universe, Marcia Bartusiak, editor, Chapter 36, "General Relativity and the Solar Eclipse Test", p. 303 and 629. Bold emphasis is mine: Einstein...

Arramon asks: what percentage of our visible universe is this Ultra Deep Field image of? I take his query to mean "What area of the celestial sphere does the UDF cover?" I did a Google search using the keywords "arcsec hubble ultra deep field." From the page hits, it appears the ...

Dan writes: However, every second, every day, the "visible" universe gets larger because more light arrives at Earth. I'm not certain the above is a correct statement. We already see the light from the Big Bang. If the visible universe is getting bigger, it is because the universe continue...

Yours is an interesting question, and I hope someone more knowledgeable than I will address it. It seems all spirals do indeed have enormous black holes at their centers. Andromeda apparently has two. I wonder if black holes exist in irregular and elliptical galaxies as well, and how these black hol...

I seek a web page that would show the two separate paths of Huygens and Cassini about Saturn. I am having difficulty understanding where the two spacecraft are and why the probe is three weeks away plunging into Titan.

No. That APOD only shows an image of the comet, not the path it will be taking through the solar system.

About the closest example of what I seek is

Can anyone point me to an image or plot of the trajectory of the new Comet Machholz? I know NASA or other organizations often produce a 'map' showing the sun, planetary orbits and the trajectory of a particular comet, and I would like to understand the path of this comet in relation to the solar sys...
