The most recent issue of Free Astronomy Magazine (September-October 2020) is available for your reading and downloading pleasure at www.astropublishing.com.

September-October 2020 includes a selected survey of astronomical content of local and cosmological interest from NASA/ESA, ESO, ALMA, as well as two feature articles from our fearless leader/editor Michele Ferrara. The feature articles in this issue discuss:

  1. “Betelgeuse – 100 years of uncertainties” – this article was 100 years in the making, but found itself updated with as-of-August scientific reporting in the final 100 hours before going to print (well, 150). The previous (pre-August) analyses were believed to be an adequate explanation, then the new reports indicate that that previous explanation did not, by itself, explain everything observed by us all since late last year.
  2. “In the mind of ET” – Continuing a multi-issue exobiology thread, this next article is a very interest perspective on the state of the search for extraterrestrial intelligence (and not just SETI), based on the recent NASA award of Adam Frank (and collaborators) at the University of Rochester.

July-August 2020 includes a selected survey of astronomical content of local and cosmological interest from NASA/ESA, ESO, ALMA, as well as three feature articles from our fearless leader/editor Michele Ferrara. The feature articles in this issue discuss:

  1. "All the planets of Proxima Centauri" – the science for this article was quite literally being published as the article itself was being put together, about as fast a processing of journal-article-to-magazine as one can do while putting others together.
  2. "A supernova or Sagittarius – which should we thank?" – I've mentioned in many lectures that our own Sun is either the second or third stellar inhabitant in our vicinity, with a local supernova sparking the formation of it and our Solar System way back when. Recent studies indicate that other events 5-ish billion years ago might have instigated the events that lead to "us."
  3. "The principle of mediocrity and the habitability of galaxies" – lump this use of the word "mediocrity" with the scientific use of the word "theory," please. It is a joy to know that fundamental debates are being had in the astronomy and astrophysics literature and that there remains plenty, plenty yet to know for those pondering their futures in STEM.
