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.

Examination of spectral data acquired from orbit show that some of these sediments have minerals that indicate chemical alteration by water.

Slightly late to the posting game – the January-February issue of Free Astronomy Magazine is available for your reading and downloading pleasure. Highlights from the original content (h/t Michele Ferrara) include an excellent introduction to panspermia and the wonderful ways in which small, dense solar systems (like TRAPPIST-1, one of the only solar systems with its own website – www.trappist.one) might serve as test beds for better understanding if such an explanation is applicable to ourselves and our Earth – either from a local source (Mars?) or from the greater beyond.
