Starship Asterisk*

looks more like it was hit by a comet

there seems to be a hole in the middle for hyperion

haha! Zeus showing off his muscle

makc are u jealous?

makc, is there a need to emphasize my older name such as

(aka N00b)

?

And how long does light travel from the Sun to the 'Object larger than pluto'? It might well be another star satelite.

Could it be from two smaller bodies? That rings a bell about how big and dense an object must be before it will naturally mold itself into a ball shape from it's own gravity. I think Iapetus is about 900 miles? That is a possibility I think also, but I doubt it is the answer. But how did it get its...

Is it possible that an asteriod hit iapetus and rip out all the surrounding rocks but it stops at the ridge and the rock thrown off the surface became Saturn's rings?

Is it possible for any objects further than Pluto to be bigger?

And does anyone know if the planet have any moons?

EDIT: July 31 APOD

k thanks

i still can't see the nebulae even after adjusting the contrast and brightness why is it so?

I feel that we are immigrants from mars about finding that ice caps..

U could check out the nasa website for that information...

I don't think astronomers have any answers about that...

Who is RJN anyway i don't get it...

naaaaaaa. i am just stupid, thats all!

It was already explained in that picture

What are the scientists were thinking about? What are chances that aliens would be able to decode this message ? Starting on pure technical side of how would they gues the way this picture were encoded (dimensions/colors/etc), or how to figure out that this was actually a picture - and, on "co...

The more times a star orbits its host galaxy, the more erratic its orbit becomes, and some stars end up being ejected.

Facinating.

thanks. your pictures are really good.

It is a tiny planet entering Earth with reflective shield to reflect things and when its near our atmosphere, it closes it's shield to avoid overheating it.

I came across a similar object while writing up a talk on planetary nebulae a few days ago. Apparently a star knowns as Vela -X1 is moving at high speed and seems to be ejected from the Gum nebula. APOD describe it as a "Runaway Star". Funnily enough it is also a Pulsar. The image can be ...

Is there any more much detailed pictures of pluto and its moon?
