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.

The November-December issue of Free Astronomy Magazine is available for your reading and downloading pleasure.

To the digest of NASA/ESA articles, excellent updates for a slew of extra-solar research, and general all-around fantastic aggregation of relevant images to make you wish you’d gotten a tablet with higher resolution, this issue wades Andromeda’s-shackled-ankle-deep into recent events at the Sunspot Solar Observatory on/at Sacramento Peak, New Mexico. Depending on your interpretation of events (and, possibly, your choice of late-night radio listening), you may or may not be satisfied with the description and resolution of the circumstances in the article or in the several follow-up news articles concerning the closing-up of the investigation.

Free Astronomy Magazine – September-October 2018 Issue Available For Reading And Download

Above: ESA’s Mars Express has used radar signals bounced through underground layers of ice to identify a pond of water buried below the surface. This image shows an example radar profile for one of 29 orbits over the 200 x 200 km study region in the south polar region of Mars. The bright horizontal feature at the top corresponds to the icy surface of Mars. Layers of the south polar layered deposits – layers of ice and dust – are seen to a depth of about 1.5 km. Below is a base layer that in some areas is even much brighter than the surface reflections, while in other places is rather diffuse. The brightest reflections from the base layer – close to the centre of this image – are centred around 193°E/81°S in all intersecting orbits, outlining a well-defined, 20 km wide subsurface anomaly that is interpreted as a pond of liquid water.

The September-October issue of Free Astronomy Magazine has been up for a few weeks now and I hope you were already aware of that from the CNY Observers post about the same.

I’m also pleased to report a promotion from contributing translator to contributing author this month with the publication of the cover story “A Possible Subglacial Lake On Mars.” For the local record, a PDF of the article (with cover and edition TOC) is available for direct download at 5FAM2018_dgallis.pdf and I can now say that my work has been published in over three languages (four, to be exact, including English, Spanish, French, and Italian).
