    Brian Clegg's acclaimed popular science book Inflight Science explored the science experienced on a plane flight. Interstellar Tours takes that concept and goes large. It takes the reader on a tour of our galaxy on the starship Endurance. 
 
That vessel itself is science fiction. But the phenomena you will visit, from the vast nebulae that are birthplaces of stars to stellar explosions in vast supernovas, creating the elements necessary for life - or from the planets of other solar systems to the unbelievably supermassive black hole at the heart of the Milky Way - all reflect the best picture that current science has to offer. 
 
Accompanying Interstellar Tours is an online gallery with over 50 images and videos in full colour, each directly accessible from the page using QR codes.

    You’re pro-life. But can you explain why?You already believe in choosing life. But when the counterarguments are coming at you from every angle—legal, biological, medical, ethical, moral, philosophical, and biblical—how do you defend the pro-life view? And as you defend it . . . how do you speak with wisdom, humility, and compassion?Now more than ever, the times call for a balance of truth and mercy. There are good, wise, and thoughtful rebuttals of every claim made by pro-abortion advocates. Collected here in one place, Choose Life offers you reasonable responses from leading experts in their respective fields. The authors are accomplished women and men from all walks of life. They’ll help you know what to say—and why to say it—when you’re faced with claims like:“The courts have already settled the issue.”“The fetus is not a person.”“My body, my choice.”“I shouldn’t have to raise an unwanted child.”“My circumstances justify ending my pregnancy.”“Abortions are helpful to women and society.”“The pro-life movement doesn’t care about social justice.” 
 
It’s time to set aside the strident fist-shaking and hurled insults. Learn to make the pro-life case with intelligent arguments and compassionate love—just the way a Christian should.
