Head to the Space.com Facebook Page tomorrow (Feb. 3) at about 12:15 EST (1715 GMT) for a chance to win an autographed copy of the new book "Earth in Human Hands" (Grand Central Publishing, 2016) by NASA astrobiologist and science communicator David Grinspoon

The new book gives readers "a more hopeful way of looking at the human role on planet Earth," according to a statement from the publisher. With information about how humans are altering the major physical systems of our planet, Grinspoon's book is ultimately a guide to how we got to this point and "how we should respond to that knowledge." 

The new book "Earth in Human Hands" (Grand Central Publishing, 2016) is now available.
