Lol,

This may sound weird but when I was younger I used to think that there was a place just like earth out there but everything was the complete oppisite.....In other words I thought blacks 'ran tings'. But now mi think different!!!!

LOL! I used to imagine that too. I wish there was another 'earth' where we're running things because they need to come down here and show us how tings gwaan.

How do we know those are real?

No planet is a perfect sphere... then again how do I know. Never been to any.

 

Anyway... carry on.

 

Got a little bored myself.

Just to think our own sun is literally a speck of dust compared to other stars in the universe is just crazy.

Peace.

What a wonderful post!

Surely it brings tears to ones eyes the magnificience of the Universe?

Look at the size of the Sun compared to Antares.... incredible! Science cannot calculate the meaning of this world. All the things which have past.... all the things which will come.... stars larger than Antares are yet to be born, stars larger than Antares have already been born and died....

Peace

Nice pics.  More intriguing is the distance between those bodies.  You can't find a scale model online because it won't fit on a page.  If you the sun the size of a bowling ball then pluto would be like a football field away from it.  The closest star to your bowling ball would be on another continent.  Stupidly far.  Yet people watch movies and think spaceflight between galaxies is a minor LOL LOL

Looking at all those, the Earth looks like a freak of nature compared to the rest them. Quite unique.

People been trained to think that way... teleportation(if possible) is a much faster way of travel, I liken it to cut and paste, mind you don't get cut and pasted in parts.

SATURN ISN'T A PLANET!

ITS MADE OF GAS

Also the moon dosen't glow, it reflects the sun.

Also it's debatable whether Pluto is a planet. Scientists reckon that it's an escaped moon that managed to get away from the gravity pull of another planet.

It's a planet, or the same could be said for Mercury, which more than likely used to be a moon around Venus.

A moon orbits a planet.  A planet orbits the Sun.  Pluto may have been a moon at one time but if so it got a promotion unless they want to claim it is an asteroid.

The gas giants can't be gas all of the way to their cores.  The moon has craters showing its bombardment by asteroids how many must have Jupiter caught in millions of years?

There are many ideas about Pluto obviously ideas only because nobody was around to see what happened.  Some people think it was one of the many bodies from that region of the solar system, the kuiper belt or oort cloud that got pulled into an orbit around the sun by Neptune, others that it was one of Neptunes moons that was bounced free or collided with something else and so on.

@ Umbrachist
That's one of the reasons earth is lucky to have Jupiter and to a lesser extent the other gas giants.  They act like cosmic vacuum cleaners pulling in bodies with their massive gravities that might otherwise come bashing into the inner planets.

Some people also think Jupiter is the reason that the asteroid belt between Mars and itself never formed into a planet, because it's massive gravity prohibited the material from coalescing, but for me that doesn't explain how Jupiter itself happens to have 20 odd planet sized moons of it's own.  They haven't been pulled apart, not even Io.  I prefer the idea that says there once was a planet there but something bashed into it and blew it to bits simply because it sounds far more exciting LOL

 

@all
Try to read about the moons of the gas giants, especially Jupiters big 4 and some of Saturn's.  They are far more interesting than the planets they orbit!

Jupiter's Galilean moons:












These are the four Galilean satellites. They are named so because they were the only four moons that Galileo was able to see. They are also the largest of Jupiter's moons. From top-left in a clock-wise direction, they are Ganymede, Callisto, Europa, and Io.



If Ganymede were not bound to Jupiter, it would be considered a planet in its own right. It is actually bigger than Mercury, being 390 km (234 miles) larger in diameter. It has heavily cratered dark regions, with lighter expanses in-between. Geologists think that it used to have plates, like the Earth, but they froze together soon after Ganymede's birth.



Callisto, the outermost of the Galilean moons, is almost an exact twin of Mercury in size and appearance. Every square mile is covered with craters or other signs of bombardment. Other than that, there are no distinct characteristics



Europa, closer to Jupiter than Ganymede, is the smoothest natural body in the solar system. It resembles a billiard ball until seen very close-up. At that distance you can start to see dark, deep, and narrow cracks. In scale, though, the relief is no bigger than a line on a billiard ball made with a felt-tipped marker. Geologists think that Europa has liquid water underneath the icy surface - and possibly life.



Io, closer yet, is commonly compared to a pizza. Its volcanoes make it the most active world in the solar system. They spew out the sulfuric acid that gives Io its many colors. They also make Io one of the only three moons with an atmosphere in the solar system. Saturn's Titan and Neptune's Triton are the other two moons. Io is similar in size and composition to our moon. Io is caught in the middle of a tug-of-war between Jupiter and the other moons. Tension has melted the interior and raised the surface temperatures so high that scientists calculated that it generates the most heat for its size of any body in the solar system, except for the sun.



Saturn's Moons:



Titan, the Largest Moon of Saturn
Titan has an atmosphere. This can be seen faintly in the image on the left as an outline, and more clearly in the following image



taken by Voyager looking back at Titan and showing sunlight scattering in the atmosphere. The atmosphere of Titan has several layers of haze. It has a pressure at the surface of 1.6 times that of Earth, and is made up primarily of nitrogen, with about a 1% concentration of methane. The temperature on the surface is very cold, about -180 degrees Celsius. The atmosphere is extremely opaque because of thick smog that appears to result from sunlight interacting with hydrocarbons, much as smog forms on the Earth.
The clouds are probably composed of liquid nitrogen and methane drops, and it is speculated that Titan may be coverered with hydrocarbon lakes or oceans (specifically, methane and ethane). Although many of the organic chemicals thought to have been the precursors to life on Earth are present on Titan, it appears to be too cold for life as we know it to have evolved there. Here is a movie of infra-red images of Titan made with the Hubble Space Telescape. The structure shown in this animation represents heat variations in the atmosphere and surface of Titan.

Saturn's other Moons
Saturn's other moons have icy surfaces that are very cold so that ice is as rigid as rock and craters form from meteor impacts. The mean densities of these moons are 1.0 to 1.5 g/cc, implying that they are probably mostly ice, though they may have some rocky consituents. Most of Saturns satellites (as for those of Jupiter) are tidally lockedand keep the same face turned toward the planet as they orbit.




Ipeatus






Rhea





Iapetus
The preceding images show the satellite Rhea, which is seen to have many impact craters, and Iapetus, which has one side that is 10 times darker than the other.

Other moons of Saturn include Mimas, which has an impact crater 1/4 the diameter of the moon, Enceladus, which may be geologically active because of tidal heating by Saturn, Tethys, which has a large flattened crater that is 1/2 the diameter of the moon and a very large canyon, and Dione, which is heavily cratered with ray structures associated with some craters.


Two small moons have been found to share Tethys's orbit, and one small moon shares Dione's orbit. This sharing of orbits had not been seen before the detailed investigation of Saturns system.

Hyperion rotates chaotically because of the influence of Titan's gravity and a highly eccentric orbit.

The outermost satellite, Phoebe may be a captured asteroid.
