Earth Space Science

We are the last humans. We are hunted. We are refugees. We must return to Earth. The alien scorpions attack us across the galaxy. They butcher millions. Humans are now an endangered species. But we have not given up. We still have a few starships. We still have some hope. And we have a map home. On Earth, we can be free again. On Earth, we can stand tall. On Earth, we can rebuild what we have lost. Earth is but an echo, calling from beyond the darkness. We will answer her call. We will find our lost world. We will defeat our enemies. We will rise again!

Critically acclaimed author Alastair Reynolds holds a well-deserved place “among the leaders of the hard-science space opera renaissance." ( Publishers Weekly).

Humanity pushed its way to the stars—and encountered the Gbaba, a ruthless alien race that nearly wiped us out. Earth and her colonies are now smoldering ruins, and the few survivors have fled to distant, Earth-like Safehold, to try to rebuild. But the Gbaba can detect the emissions of an industrial civilization, so the human rulers of Safehold have taken extraordinary measures: with mind control and hidden high technology, they've built a religion in which every Safeholdian believes, a religion designed to keep Safehold society medieval forever.

It’s been eight years since an alien invasion drove a small surviving group of settlers to seek refuge in an underground shelter. Cut off from the rest of humanity, the ragtag band has maintained a narrowly functioning colony due to communal effort and salvage runs. Alex Archer has her own duties as a dog handler. While this off-world colony may be harsh, Ash, Alex’s black shepherd raised to sense threats, makes living in it a little nicer.

There is a milestone in the evolution of every sentient race, a Tech Singularity Event, when the species achieves transcendence through its technological advances. Now the creatures known as humans are near this momentous turning point. But an armed threat is approaching from deepest space, determined to prevent humankind from crossing over that boundary - by total annihilation if necessary.

For Sheriff Duke, the danger has reached the final countdown. Captured, tortured, beaten, but undefeated, it’s 60 seconds to midnight, and the only way to save his wife and daughter is through the fugitive he left home to hunt.

These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

With the invention of faster-than-light travel there is nowhere that humanity cannot go. New worlds are discovered, but with them come new dangers. At the heart of the discovery is the Fermi, mysterious beings that have survived on alien worlds for longer than humanity has existed.

Their search for answers will take them to places, and worlds, they never expected.

In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.
