After being in print for twenty years, the Chronological Encyclopedia of Discoveries in Space, covering everything that was learned on every single space mission in the 20th century, has finally gone out of print.

 
I presently have my last four hardback copies available for sale. The book sold new for about $90. To get your own autographed copy of this now rare collector's item, please send a $120 check (which includes shipping) payable to Robert Zimmerman to

"Useful to space buffs and generalists, comprehensive but readable, Bob Zimmerman's Encyclopedia belongs front and center on everyone's bookshelf." -- Mike Collins, Apollo 11 astronaut

 

"The Chronological Encylopedia of Discoveries in Space is no passionless compendium of information. Robert Zimmerman's fact-filled reports, which cover virtually every spacecraft or probe to have ventured into the heavens, relate the scientific and technical adventure of space exploration enthusiastically and with authority." -- American Scientist

As predicted by astronomers, Betelguese’s dimming has ceased and has even begun to brighten slightly in the past week.

The graph here and at the link shows the uptick clearly. As this was exactly what was expected if the star followed its past cyclical patterns, this strongly suggests that we will not see any supernovae from the star anytime in the near future.

    Amazing. We have had nothing but rain here in Georgia the last few weeks but last night was clear as a bell. I went out specifically to look at Betelgeuse to see if it was dimmer than it was a few weeks ago when I noticed it was much dimmer than memory served.

    So I looked and thought, not only is it NOT dimmer, but it’s a little brighter than last time I looked. Now I have 68 year old eyes and was only out for 10 minutes and we are next to I-85 so, far from being optimum viewing. So I don’t know if I was fooling myself, or it really is that variable a star.

    Sad about no Supernova though. Would have been cool and I don’t think I’ll make it the 5000~100,000 years predicted.
