Some 900 million miles from the Sun in the outer regions of our Solar System orbiting the planet Saturnlies a mysterious world. Enceladus is enveloped in ice. Because nearly all of the sunlight that manages to hit its surface is reflected back into space, its one of the brightest objects in the solar system. It turns out that this distant outpost may harbor subsurface oceans and pre-conditions for life.

Just about every two years, the planet Mars makes its closest approach to Earth around 36 million miles. Thats when we pack our robotic emissaries off to the Red Planet, timing their launches to spend the least effort to get there. These probes may pave the way for human explorers and, perhaps permanent settlers wholl dig deeper still in search of answers to our most pressing question: Did Mars develop far enough and stay that way long enough for life to arise?

The universe has long captivated us with its immense scales of distance and time. How far does it stretch? Where does it end and what lies beyond its star fields and streams of galaxies extending as far as telescopes can see? These questions are beginning to yield to a series of extraordinary new lines of investigation and technologies that are letting us to peer into the most distant realms of the cosmosBut also at the behavior of matter and energy on the smallest of scales. The mind-blowing answer comes from a theory describing the birth of the universe in the first instant of time.

The Largest Black Holes in the Universe

We’ve never seen them directly, yet we know they are there, lurking within dense star clusters or wandering the dust lanes of the galaxy, where they prey on stars, or swallow planets whole. Our Milky Way may harbor millions of these black holes, the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there’s evidence of something even more ominous: a breed of black holes that have reached incomprehensible size and destructive power. How big can they get? What’s the largest so far detected? Where does an 18 billion solar mass black hole hide?
