We’re Going Multiplanetary: The Quest for New Earths - Guest Work
Guest Author • Jun 29, 2018 •
Becky Turner Theoretical physicist and one-man-phenomenon Stephen Hawking contributed a wealth of knowledge to mankind during his lifetime. One of his recommendations was that humans would need to colonise other planets in the next hundred years to avoid annihilation. His fears took the form of deadly viruses, nuclear war, asteroid impacts, and global warming. In order to avoid … Read More

Ian Crawford, UCL The search for life elsewhere in the universe is one of the most compelling aspects of modern science. Given its scientific importance, significant resources are devoted to this young science of astrobiology, ranging from rovers on Mars to telescopic observations of planets orbiting other stars. The holy grail of all this activity would be … Read More
