Are We Alone?

Is alien life real--or just science fiction?

This book takes curious readers on an epic journey through astrobiology, the science of searching for life beyond Earth. Starting with Earth itself, discover what makes our planet so special--and whether anything like it exists out there in the stars. From ancient alien theories to cutting-edge telescopes and rovers, explore how scientists search for evidence of life in our solar system and beyond.

You'll uncover:

• The key ingredients for life--and what happens if life breaks the rules
• What alien life might look like (spoiler: not little green men!)
• Why humans might be the aliens someday

With cool, graphic-style illustrations combined with jaw-dropping facts, Tomorrow's World showcases science like never before--as something that can truly change the world!
