No one has ever ventured deeper into space than the four astronauts of Shepherd-1. The aim of their mission is to witness the creation of the cosmos. Using the sun as a lens, they are to align a flock of probes in such a way that the moment of the Big Bang becomes visible. For astronomer Christine, this is a dream come true. So she is bitterly disappointed when the first images are obscured by a kind of veil that prevents any insight. She works obsessively to find a solution, but when she finally succeeds in lifting the veil, she sees something that would have been better kept hidden...

A mysterious object threatens to destroy our solar system. The survival of humankind is at risk, but nobody takes the warning of young astrophysicist Maribel Pedreira seriously. At the same time, an exiled crew of outcasts mines for rare minerals on a lone asteroid. When other scientists finally acknowledge Pedreira's alarming discovery, it becomes clear that these outcasts are the only ones who may be able to save our world, knowing that the Hole hurtles inexorably toward the sun.

For many billions of years, humans - having conquered the curse of aging - spread throughout the entire Milky Way. They are able to live all their dreams, but to their great disappointment, no other intelligent species has ever been encountered. Now, humanity itself is on the brink of extinction because the universe is dying a protracted yet inevitable death.

NASA finally made it. The very first human has just set foot on the surface of our neighbor planet. This is the start of a long research expedition that sent four scientists into space. But the four astronauts of the NASA crew are not the only ones with this destination. The privately financed "Mars for Everyone" initiative has also targeted the Red Planet. Twenty men and women have been selected to live there and establish the first extraterrestrial settlement.

It is 2056. Mathematics professor Elisabeth Gabai is fascinated by multi-dimensional forms that have no equivalent in reality. Then, her boss sends her to the site of an artifact that might have come straight from her theories—or from the technology of an advanced civilization. Twenty-eight years earlier, physicist Max Webber is hell-bent on improving Einstein’s theories of relativity. His latest concept seems flawless, except it predicts the end of humanity. The extinction of Earth can only be prevented if Max can locate a multi-dimensional object.

Judith Rosenberg, captain of the spaceship ARES, is under pressure. After the previous mission to Mars crashed, she is supposed to set down the first humans on the Red Planet. Maxim Goncharov, meanwhile, has other problems to contend with. He's in charge of building an international lunar base at the moon's south pole, where the sun almost always shines. But his crew is slowly running out of resources

Daniel Rice is a government science investigator whose specialty is solving seemingly intractable problems through scientific inquiry. But Daniel's intellectual strength is sorely tested by the bizarre realities he finds in the quantum world. Extra dimensions of space trap the unwary, probability replaces cause and effect, and time isn't what anyone imagined. The other side of the mirror is a place full of dangers, but it's also somewhere a dedicated scientist can uncover secrets that connect humans with something greater.

Dr. Tyson Klein is a quantum physicist who has dedicated his entire life to his research. At CERN, he analyses data generated by the Large Hadron Collider, the world's biggest and most powerful particle accelerator. Now, Ty believes he's found a pattern in its output. It looks like an organised data stream, being broadcast over what he calls a quantum radio. Could it be a signal from another universe? A message sent from the future? Or something else entirely?

Commander Scott McNabb and the crew of the science vessel, Hermes, are three years into a five-year-long survey of the asteroid belt when they discover a derelict spaceship in orbit around a binary asteroid. The ship contains an experimental quantum device, lost while en route to a research colony on Europa.

Nick Morrison always wanted to be an astronaut. When a start-up company recruits him to build a lunar launch system at the moon’s south pole, Nick gladly leaves behind his troubled life on Earth—but Nick doesn’t know that the company is in financial and legal trouble. Deprived of support from Earth, the team on the moon must figure out how to survive on their own. Worse yet, there’s another base at the lunar south pole, run by a ruthless contractor who has big plans for the moon...and for Earth.

Jeff Dolan always wanted to be an astronaut. After helping a private space company build a ship that can travel to Saturn's largest moon in five months, he gets his chance. Shortly after launch, a devastating malfunction forces Jeff and the crew to make a choice: continue to Titan or go back home. As the truth about their mission unravels, one thing is clear: Someone on Earth knew about the system flaw and covered it up. Yet surviving the journey isn't the crew's only concern. Even if they make it to Titan, they will face another problem: Something is already there.

I wasn’t supposed to survive. The station has been hit. Everyone around me is dead. I have 11 hours of life support left and no way of contacting Earth. I’m alone. I’m stranded. I’m desperate. But I’m alive. The more of the station I explore, the surer I get that this was no accident. Someone did this, and I don't think they're finished yet.

The ice is coming. It was the last thing we expected, but the world is freezing. A new ice age has dawned. Billions have fled the glaciers. A cataclysmic war is coming. In orbit, a group of scientists are running the Winter Experiments, a last-ditch attempt to understand why the planet is cooling. None of the climate models they build make sense. But then they discover an anomaly, an unexplained variation in solar radiation...and something else. Close to the burning edge of the sun, they catch a fleeting glimpse of something that shouldn’t be there....

In April 1970, during the glory days of the Apollo space program, NASA sent Navy Captain Jim Lovell and two other astronauts on America's fifth mission to the moon. Only 55 hours into the flight of Apollo 13, disaster struck: a mysterious explosion rocked the ship, and soon its oxygen and power began draining away. Written with all the color and drama of the best fiction, Apollo 13 (previously published as Lost Moon) tells the full story of the moon shot that almost ended in catastrophe.

When Manchester Yards donates a new training vessel to the Merchant Officer Academy at Port Newmar, Alys Giggone recalls the Chernyakova. She wants Ishmael Wang and his crew to take a crew of cadets into the Deep Dark. They have to sort out the crews of two ships, figure out what lessons they need to teach, and who will get those lessons. Once they agree, the trouble starts.

When Simon and Katherine Hawke stumble upon an alien shuttle that has landed on earth, it’ll not only change the course of their lives, but of the entire world. Taking the shuttle into orbit, they discover a much larger ship left adrift with no one on board. Commandeering it, they confirm that we’re not alone in the universe and must prepare the human race for what is about to come. Recruiting from all over the world, they begin to expand their fleet and build a federation to give humans a foothold in the galaxy.

Pilot X is Ambassador of the Alendans, a race with the ability to move through space and time as guardians of the timeline. Locked in ongoing conflict with the Sensaurians, an organic hive mind that can send messages in thought throughout its own history, and the Progons, a machine race who can communicate backwards in time, Pilot X finally manages to create peace among the three races.

The crew of Moonbase Columbus makes an amazing discovery on the far side of the Moon - a massive alien structure is erecting itself, built up atom by atom by living machines, microscopically small, intelligent, and unstoppable, consuming everything they touch. The mysterious structure begins to expand and take shape, and its creators begin to multiply. Is this the first strike in an alien invasion from the stars? Or has human nanotechnology experimentation gone awry, triggering an unexpected infestation?

Humans call them Monument-Makers. An unknown race, they left stunning alien statues scattered on distant planets throughout the galaxy, encoded with strange inscriptions that defy translation. Searching for clues about the Monument-Makers, teams of 23rd century linguists, historians, engineers and archaeologists have been excavating the enigmatic alien ruins on a number of planets, uncovering strange, massive false cities made of solid rock. But their time is running out.

Any kind of death annuls everything except his present knowledge and returns him to the past. This is a good way to test all sorts of things. That is, it would be, if not for one little thing.... This loop has real lords and it's unlikely that they'll be happy to hear about an uninvited guest. And that isn't his only problem - all of his memories of the last year have simply disappeared, but the world around him has changed in the meantime.

At the turn of the 22nd century, scientists make a breakthrough in human spaceflight. Through a revolutionary method known as somaforming, astronauts can survive in hostile environments off Earth using synthetic biological supplementations. With the fragility of the body no longer a limiting factor, human beings are at last able to journey to neighboring exoplanets long known to harbor life. A team of these explorers, Ariadne O’Neill and her three crewmates, are hard at work in a planetary system 15 light-years from Sol, on a mission to ecologically survey four habitable worlds.

Cities all around the world reported strange alien vessels descending. Some saw them as the heralds of a new age; others fired everything they had at them. All were taken as the beams lashed down and drew them into the sky. Dean was left behind, seemingly the last man on Earth. A trail of clues left by his dead wife guides Dean on a perilous journey across America and beyond to learn the truth behind the mysterious ships and save humanity from its doom.

When prospector Bob Broadhead went out to Gateway on the Heechee spacecraft, he decided he would know which was the right mission to make him his fortune. Three missions later, now famous and permanently rich, Robinette Broadhead has to face what happened to him and what he is...in a journey into himself as perilous and even more horrifying than the nightmare trip through the interstellar void that he drove himself to take!

Logan West and Emma James grew up together but are now high school seniors going in totally opposite directions after graduation. When they are assigned to work together on one last history project, they hardly expect the monotony of high school life to change. Instead, as they decode a series of unexplained clues hidden within their history project itself, Logan and Emma manage to unfold an ancient mystery that has baffled scientists and archaeologists, one with powerful implications for the present day.

A scientific experiment begins, and as the button is pressed, the unexpected occurs: everyone in the world goes to sleep for a few moments while everyone's consciousness is catapulted more than twenty years into the future. At the end of those moments, when the world reawakens, all human life is transformed by foreknowledge.

The Galactic Star Alliance has been alive and well for millions of Earth years. Hundreds of thousands of worlds and trillions of beings move across the many home worlds of the Alliance. This revelation invites many questions: How is faster-than-light speed travel possible, and could cohesive, interstellar civilizations exist without it? Is it conceivable to govern a coalition not of different countries but of different species?

People love easily. Look at most of your relatives or coworkers. How lovable are they? Really? Yet most have mates and children. The vast majority are still invited to family gatherings and their relatives will speak to them. Many have pets to which they are devoted. Some even call them their fur-babies. Is your dog or cat or parakeet property or family? Not in law but in your heart? Can a pet really love you back? Or is it a different affection? Are you not kind to those who feed and shelter you? But what if your dog could talk back? Would your cat speak to you kindly?

The saga of two young friends trapped in an endless nightmare of suspicion and surveillance, of cyber-programmed servants and a ruling class with century-long lives – and the enigmatic woman who dominates them all.
