With the search for ET undergoing a massive leap in recent years, interest in all things Extraterrestrial has never been higher. Could we soon have the answer to that biggest of Big Questions: are we alone?

There have been some very credible UFO sightings, and a US physics professor thinks science doesn’t take them seriously enough. Could a more thorough investigation of flying saucer sightings open up a whole new trail in the hunt for Extraterrestrial life?

Sending greetings out into the galaxy might put us at risk of an alien invasion. Is making contact the equivalent of shouting in a jungle full of dangerous creatures? If so, perhaps we should stay quiet?

What would life on other worlds be like? Astrobiologists and philosophers use science and principles of evolution to make predictions. Could intelligent aliens be similar to us? Are there Extraterrestrial dolphins? Or could ET be something utterly strange?

Highly developed alien civilisations could have incredible technologies, so advanced they appear like magic to us. Astronomers think we should be able to detect these with today’s telescopes and have begun this search. How would the discovery of super alien tech transform us?

While most alien hunters are searching for ET and dreaming up new ways to make contact, there are certainly sceptics. They say aliens simply don’t exist, and that we are completely alone in the entire galaxy. What does this mean for the future of humankind?

Could intelligent aliens be utterly unlike us? Might ET have visited the Moon long ago and planted hidden technology? Some scientists are starting to think outside the box, and are considering extreme alien hunting.

We could find evidence of alien life very soon. A $100 million search is underway with new telescopes currently being constructed, including the biggest radio telescope ever built. With new ways of looking for ET life, what extraordinary things might we discover?
