Yeah, I know, it's not Friday, but I had to post about the lander that crash landed on Mars yesterday. So This Blog's History post is coming to you on a Monday.
With more and more exoplanets discovered by astronomers every month, and more of these exoplanets residing in a stellar system's habitable zone, it begs the questions, how much longer is Earth habitable. I addressed this several weeks ago and point you to my discussion on this for This Friday in This Blog's History.
Spoiler: It's a long time, but not as long as you think.
How Much Longer is Earth Habitable?
