The most recent issue of Free Astronomy Magazine (November-December 2019) is available for your reading and downloading pleasure at www.astropublishing.com (click the link to go directly to the issue).
As editor-in-chief Michele Ferrara alludes to early in his "flexible concept" article on page 38, there's been quite the transition into the study of exoplanets and the potentials for habitability as a way to more credibly have the discussion about alien life.
His article on page 22 is worth the read for those who think it's not a question of "if" but of "how often?"
For those wanting a quick look at what the issue has to offer, the Table of Contents is reproduced below.

The March-April 2019 issue of Free Astronomy Magazine is available for your reading and downloading pleasure.
To the several NASA and ESA highlights included in this bi-month's issue (including a wonderful collection of Spirit and Opportunity images in celebration of Opportunity's recent end-of-mission status announcement), Michele Ferrara has managed to both (a) make you hopeful about our future as a science-spreading civilization in the galaxy and (b) remind you how far we have to go here on Earth to improve our appreciation of that same galaxy. Hopefully, the Genesis Project (no, not really that one (but sort-of). This other one – besides this issue, see phys.org and universetoday.com) and Orbital Advertising (not going to dignify it with additional links) articles give you deep – and different – pause.
