Re: APOD: Annular Eclipse After Sunrise (2017 Mar 02)
Shouldn't the sun be moving up and to the right, towards the south and eventually the west. or do things work "backwards" in the Southern hemisphere? Travel to the southern hemisphere (as I have), and it’s amazing how fast you’ll notice that the Sun rises in the “wrong” direction. I’m sur...

I would have been good to precise that the round colored halos around all bright stars are not nebulas but reflections in the optics! They are very visible and I think that's confusing for most people. :) A larger question is how much information should the editors repeat from the original image pa...

True. Fluids and solids can share many properties that gases do not, however. [...] Shouldn't that be liquids and solids? I used "fluids" deliberately, since gases, liquids, and solids are all capable of existing as fluids, and it is the fluid properties that allow something to act (at le...

Tasco won’t focus
We have a brand new astronomy club in St. Thomas, and a couple of weeks ago, we had our first star party. One child and his grandmother showed up with a Tasco 420x60 refractor. They obtained it in the usual manner: it was gifted to them. I was prepared to focus on the positive, and give them tips on...
