The link did not work for me, however, if it is a giant, it may not have had time to consolidate. Saturn could "float on water". It hasn't had time yet to get denser, like Jupiter, presumably because its gravity is weaker, and it has only had 4.5 billion years. You have ot give these planets time.

Although a giant marshmallow is not suitable for us to live on, the small ones are very tasty.

Scientists have long debated whether Mars was once home to a large body of water.

Now, however, they’ve actually found proof of an ancient ocean on the red planet.

It is not clear what they are going to do, On one hand we hear ""The power is spread out over a such a large area that even at its peak intensity in the centre of the beam it will not be hazardous to animals or humans." If that is 2 GW, then the beam will have to have monstrous collectors. If, on the other hand, it goes to collectors as in the diagram in a relatively narrow beam, it better not miss the collectors. Suppose a small (flake of paintsize) meteor hit it and tilted it?

Bernard Smith | 3030 comments Tomorrow there is an "occultation" of Mars, that is, it disappears behind the moon. About 4am in UK.


message 1411: by Ian (new)

Ian Miller | 269 comments That figures. Whenever there is an astronomical event, it rains here, and tomorrow, rain is forecast :-( (Of course, we wouldn't see it anyway because it is in the daytime here.)

message 1432: by Ian (new)

Ian Miller | 269 comments There is a slight skimming of the sun where I am. However, since this is an astronomical event, I predict rain on that Thursday here.

Bernard Smith | 3030 comments Yes, comet Leonard. As I am unlikely to see its next visit, I will try to see it this time.
