We sure do love our celebrities, don't we? And I don't mean whatsisname, who won on American Idol last night.

Any day now (May 12 was...

Judith Young wore a light, sheer robe, almost a wrap, that reached to within inches of the floor, over silky, swishy pajama-looking clothes.

There is a brief but vociferous debate about the value of human spaceflight over at Space Politics, under a discussion of the new NASA proposed budget.

We’ve known since the beginning of the space age that the Moon has no global magnetic field. Before we returned samples from the Moon, this was thought to be well understood – compared to Earth, the Moon is a small body (1% the mass) and it rotates very slowly (almost 30 times slower).

As this rather overwrought piece at the Orlando Sentinel has been posted and commented upon endlessly at several web sites, I do not propose to rehash it. Instead, I want ...
