Lots of signals have gone into space such as TV, radar and radio. The signals have been betraying our presence for 60 years and have passed over about 6000 star systems and are reaching new systems every day. This would seem to be enough, even though we haven’t received anything back yet, but what if [...]

Good Evidence for Life on Saturn’s Moon Titan
The Cassini spacecraft has noticed on Titan, Saturn’s moon, that hydrogen molecules flow down through the atmosphere and disappear when they reach the surface (Icarus Journal). Also the hydrocarbons on the surface of Titan have been mapped and show that there is a lack of acetylne (Journal of geophysical research). The lack of acetylne could [...]

Alien Civilization Types From 1 To 7
What could an alien civilisation be able to do? Well, as we have not found any alien civilisations then everything is guesswork based on the laws of physics and our experiences here on earth. This could be completely wrong or it could be completely right or it could be somewhere in between. It is great [...]

21 Reasons We Have Not Talked To Or Found Alien Civilizations
Look up and you will see lots of dots of light. No, it’s not a load of cars screaming towards the Earth because they missed the stop sign at Mars. It’s stars. There are said to be about 140 billion stars that look like the sun in the Milky Way. There are a lot more stars [...]

Where Are All The Civilisations?
What is going on? Where are they all? Are they here? Too many questions and literally too little time. It just seems so really boring that we can be the only ones in this universe. Time is definitely a massive problem when looking for somebody alien to chat to. Does it matter that there are [...]

Does Something Unknown Lurk at the Galactic Center?
It may be a bit of a long way away (26,000 ly) but it is an interesting place to go. At 26,000 light years away it would take 26,000 years as measured by clocks on Earth at the speed of light, and no time at all as measured by your watch. Time is relative, not fixed. [...]

Using A Laser To Communicate With Aliens
A communication strategy that aliens might use instead of radio signals is to send brief and intense bursts of laser light across the galaxy – sort of like a signal lamp between two ships. Some space telescopes would be ideally suited to pluck out such a signal from the sky background. Why laser beams instead of radio transmitters? [...]
