    Earth could continue to host life for at least another 1.75 billion years, as long as nuclear holocaust, an errant asteroid or some other disaster doesn't intervene, a new study calculates.
  • UK astronomers to co-ordinate their search for alien signals

    Academics from 11 institutions have set up a network to co-ordinate their Search for Extra-Terrestrial Intelligence (Seti). The English Astronomer Royal, Sir Martin Rees, will act as patron. The group is asking funding agencies for a small - about £1m a year - sum of money to support listening time on radio telescopes and for data analysis. It would also help pay for research that considered new ways to try to find aliens. Currently, most Seti work is done in the US and is funded largely through private donation.

    As far as we know, Earth is the only place in the Universe where life has arisen, let alone developed an intelligent civilization. This baffling contradiction is known as the Fermi Paradox, first described in 1950 by the physicist Enrico Fermi. Scientists have been trying to resolve this mystery for decades, listening for radio signals from other worlds. We’ve only sampled a fraction of the radio spectrum, and so far, we haven’t detected anything that could be a signal from an intelligent species. How can we explain this?

    Scientists recently decoded the first confirmed alien transmission from outer space. It said: "Please send 5x10 (to the 50th power) atoms of hydrogen to each of the five star systems listed below. Then, add your system to the top of the list and delete the system at the bottom. Transmit copies of this message to 100 different solar systems. If you follow these instructions, you are guaranteed that within 0.25 degrees of a galactic rotation you will receive in return sufficient hydrogen stores to power your own civilization until the universe reaches inevitable maximum entropy. This really works!" OK, it's...

    Explanation: What are these Earthlings trying to tell us? The above message was broadcast from Earth towards the globular star cluster M13 in 1974. During the dedication of the Arecibo Observatory - still the largest single radio telescope in the world - a string of 1's and 0's representing the above diagram was sent. This attempt at extraterrestrial communication was mostly ceremonial - humanity regularly broadcasts radio and television signals out into space accidentally. Even were this message received, M13 is so far away we would have to wait almost 50,000 years to hear an answer. The above message gives...
  • Finding true love as rare as finding aliens?

    Romance may happen every day, but finding true love in London is as rare as aliens in the galaxy, says one London-based economist. Peter Backus, a teaching fellow of economics at the University of Warwick, has calculated that he has a 0.00034 percent chance of finding love in the British capital using the same "Drake" equation scientists use to determine the potential number of extra-terrestrials in our galaxy. American astronomer and astrophysicist Frank Drake devised his namesake equation in the early 1960s. The 31-year-old Backus -- who lives on a narrow boat in central London -- is not even that...
  • ET Visitors: Scientists See High Likelihood

    Decades ago, it was physicist Enrico Fermi who pondered the issue of extraterrestrial civilizations with fellow theorists over lunch, generating the famous quip: "Where are they?" That question later became central to debates about the cosmological census count of other star folk and possible extraterrestrial (ET) visitors from afar. Fermi’s brooding on the topic was later labeled "Fermi’s paradox". It is a well-traveled tale from the 1950’s when the scientist broached the subject in discussions with colleagues in Los Alamos, New Mexico. Thoughts regarding the probability of earthlike planets, the rise of highly advanced civilizations "out there", and interstellar travel...

    My topic today sounds humorous but unfortunately I am serious. I am going to argue that extraterrestrials lie behind global warming. Or to speak more precisely, I will argue that a belief in extraterrestrials has paved the way, in a progression of steps, to a belief in global warming. Charting this progression of belief will be my task today. Let me say at once that I have no desire to discourage anyone from believing in either extraterrestrials or global warming. That would be quite impossible to do. Rather, I want to discuss the history of several widely-publicized beliefs and to...

    The U.S. and other world governments already have detailed secret plans for first contact.When UFOs land, a series of plans created to deal with nuclear emergencies and biological attacks will be activated. Within the scientific community, the question is no longer whether extraterrestrial life exists, but if ET is smart enough to do long division. Scientists are of two minds regarding the existence of extraterrestrial intelligence. Skeptics acknowledge simple life-forms might be found on other planets, but insist that intelligent life is unique to Earth. Their belief is based on the assumption that Earth possesses unique physical attributes, including a...
