Our Moon has yielded some long-held secrets in recent weeks, from possible evidence of ancient life on Venus to NASA’s new discovery of large deposits of water.
“If space is truly infinite,” observes Dan Hooper, head of the Theoretical Astrophysics Group at the Fermi National Accelerator Laboratory, in At the Edge of Time, “the implications are staggering. Within an infinite expanse of space, it would be hard to see any reason why there would not be an infinite number of galaxies, stars, and planets, and even an infinite number of intelligent or conscious beings, scattered throughout this limitless volume. That is the thing about infinity: it takes things that are otherwise very unlikely and makes them all inevitable.”
“Any extraterrestrial organisms we find will be made of the same atoms we are,” observes Harvard’s Center for Astrophysics, Avi Loeb, about the recent detection of a potential biosignature in the atmosphere of Venus, the nearest planet to Earth where NASA is currently considering sending a spacecraft.

It has been said that all the light ever radiated by all the stars that ever existed in the history of observable universe –a bubble 14 billion light-years in radius, which represents how far we have been able to see since its beginning– is still with us, filling the universe with a sea of photons, the cosmic fog known as the extragalactic background light –providing as much illumination as a 60-watt bulb seen from 2.5 miles away.
