Carl Sagan, writer and scientist, returns from the frontier to tell us about how the world works. In his delightfully down-to-earth style, he explores and explains a mind-boggling future of intelligent robots, extraterrestrial life and its consequences, and other provocative, fascinating quandaries of the future that we want to see today.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

The Union-Congregate war rages onward, and the Union's premier fighter pilots, the Homo Eridanus, start encountering deadly resistance from strange pilots on the Congregate side. Among wreckage, they find that new Congregate pilots aren't human, but Homo quantus, with strange wiring and AI connections. At the same time, the Puppets come to the Union with offers of an alliance for a dangerous price: the rescue of the geneticist Antonio Del Casal who is a captive at Venus, with over a hundred Homo quantus.

On June 6, 1761, the world paused to observe a momentous occasion: the first transit of Venus between the earth and the sun in more than a century. Through that observation, astronomers could calculate the size of the solar system - but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.

After the Apollo program put 12 men on the moon and safely brought them home, anything seemed possible. In this spirit, the team at NASA set about developing the space shuttle, arguably the most complex piece of machinery ever created.

A novella set in the hard-scrabble world of James S. A. Corey's NYT best-selling Expanse series, The Vital Abyss is the secret history of the cataclysmic events that occurred on Eros station, and the revelation of what came after...Somewhere in the vast expanse of space, a group of prisoners lives in permanent captivity. The only company they have is each other and the Belters who guard them. The only stories they know are the triumphs and crimes that brought them there. The only future they see is an empty life in an enormous room.

Dr. Michael Guillen, a best-selling author, Emmy award-winning journalist and former physics instructor at Harvard, used to be an atheist ― until science changed his mind. Once of the opinion that people of faith are weak, small-minded folks who just don’t understand science, Dr. Guillen ultimately concluded that not only does science itself depend on faith, but faith is actually the mightiest power in the universe.

Bethany Anne Nacht was changed on Earth almost 200 years in the past. The Kurtherians engage in the cosmic great game, where whole worlds are torn asunder in their efforts to prove their own supremacy.

David K. Stumpf demystifies the intercontinental ballistic missile program that was conceived at the end of the Eisenhower administration as a key component of the US nuclear strategy of massive retaliation. Although its nuclear warhead may have lacked power relative to that of the Titan II, the Minuteman more than made up for this in terms of numbers and readiness to launch - making it the ultimate ICBM.

Former NASA astronaut Terry Virts offers an insider's guide to astronauting—a behind-the-scenes look at the training, the basic rules, lessons, and procedures of space travel, including how to deal with a dead body in space, what it’s like to film an IMAX movie in orbit, what exactly to do when nature calls, and much more, in 51 brief chapters.

In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature.
