cone nebula
Wonder what would happen if one drew a straight line thru the centerline of the cone and extended it past the photograph. Perhaps it would point to an ancient Supernovae " thing " ????

stunning , the Southern Cross is !!!!!!!!!!!!!!!
The Earth-Sun L2 Point Earth is in a stable orbit around the sun because our planet's forward motion exactly counterbalances the gravitational pull of the sun at this distance (about 93 million miles). All orbiting bodies have achieved this balance between gravitational pull and forward speed. Since...

speed of gravity
Speed of gravity gets cancelled out at L4. Oh yeah, gravity is massless and can only be detected by the influence on objects that have mass, governened by Newton's laws. Are you trying to bridge Newtonian physics to quantum physics ???? Pass the ice cold one !! Can you take a picture of the Southern...

gravitational viscosity is a summation of all the individual atom/molecule/substance attractions that occur . .

<<<<<<I don't think anyone knows for sure Harry, a lot of the rings are held in place by 'shepherd' moons that hold the particles in place - some of the moons are also replenishing the rings as technically, ring systems aren't that stable.>>>>> Isn't Saturn itself the "engine" that motors ...

The angle of the shadows indicate a low Sun angle and there is not enough atmosphere under the electric panels to diffuse the light. I wish I had the ability to draw that good............

proxima centauri
and if seen from Proxima Centauri, would the nine planets of the Sun be also seen ? other than Pluto. If the answer is yes, the third question would be can planets be seen at Proxima Centauri if they exist ???

moon over Antartica (APOD 25 Nov 2005)
Nice trick description with the insertion of " northern horizon " in the explanation . I was startled at first, knowing my geography and that Antartica is south, coupled to the fact I just saw the full moon not too long ago at 48 degrees latitute north. Fish don't smell right and the beer ...

I have often wondered if the genesis of stars is similar to the generation of current eddies inside a operating alternator in a car. Current eddies produce magnetic " things " with centers associated with said "things". Wonder if black holes are similar acting as if they contain ...

wobble
The wobble you refer to that causes seasonal changes are due to the geometry of the solar system, where the earth's orbit is tilted and follows an ellipse wjere the beast moves closer and further away from the sun every year, coupled with the tilt of the Earth. It is a perception of what we actually...

My guess is the bubble has no viscosity, other than the gravitational mat between the " Molecules " and they are all moving in formation until this gravitation becomes feeble. My dollars worth ( I said more than two cents worth )

eta carinae
Bet you an ice cold brew this thing is just going to be a NOVAE, albeit quite a bright one. Few weeks ago on APOD, it was suggested gamma rays come from two very massive object colliding and I believe Eta is a single very big object, not two. And I will buy you two ice cold brews if it is a Supernov...
