My votes this time went first,
- to the polar ring galaxies, because I see in APOD a description of these intriguing objects in 1999--there may be newer ones I am unaware of.... The Cornell U. link explaining PRGs says, there is a new catalog, and APOD astronomers can give us a learned explanation of the new findings;
- second, to the artistic representation of fire in space; I do not know anything about this, and would like to find out more about this phenomenon;
- and third, to the first observation of a comet crossing paths with the Sun. Did it crash into the Sun, or did it come between the viewer and the Sun? I cannot tell, and would like to hear an astronomer discuss this event.
All pictures here are interesting and appealing in their own right.
