It may sound cliche, but the question ‘Are we alone?’ is still one that captures the imagination of many people, including of course, scientists. With the now regular discovery of exoplanets orbiting other stars, the prospect that there may be other intelligent life out […]

Mystery Deepens: New Study Shows Comets Don't Explain Odd Dimming of Kepler's 'Weird Star'

As has been reported previously on AmericaSpace, and elsewhere, there is something weird going on around a star which is a little over 1,400 light-years away. Astronomers are still baffled as […]

SETI Detects No Alien Signals Coming from Strange Star, Continues Searching

The SETI Institute has recently undergone a search for alien radio signals around the star KIC 8462852, whose mysterious brightness fluctuations have been considered to be the workings of an extraterrestrial civilisation. Following a thoroiugh search in a wide range of frequencies, SETI reported that it has detected no such signals that could […]

Astronomers Begin Worldwide Observations of 'Unusual' Star as SETI Listens for Alien Signals

Astronomers have begun a follow-up study of the unusual star KIC 8462852 in the hopes of explaining Kepler’s enigmatic observations. To that end, the American Association of Variable Star Observers recently issued a call to the astronomical community worldwide for more detailed observations, while the SETI Institute has began searching for possible radio […]

The Kepler Discovery Controversy: Objects Orbiting New Star Likely Cometary Fragments, Not Aliens

Are the unusual objects around KIC 8462852 a giant swarm of comets or something else? Image Credit: NASA/JPL-Caltech/T. Pyle (SSC)

There has been a lot of discussion during the past several days regarding a discovery by the Kepler Space Telescope, which, according to some, might be the first evidence for advanced extraterrestrial intelligence, […]

Kepler Update: Earth's 'Bigger and Older Cousin' Discovered Orbiting Distant Star

One of the primary goals in the search for exoplanets is to, hopefully, find an Earth analog or “Earth twin,” an alien world similar to our own. That search is […]

Kepler Confirms Over 1,000 Exoplanets, Finds More Potentially Habitable Worlds

Even after problems threatened to end the Kepler space telescope’s mission for good last year, the planet-hunting observatory has continued to help astronomers discover thousands of exoplanets […]

Of Alien Life and Intelligence: Are We Ready for Contact? (Part 3)

A new study cautions that humanity isn’t yet ready to contact any extraterrestrial intelligence, while proposing that SETI should not be involved in transmitting any radio signals to other civilisations that might be out in the Universe. How accurate is this view? Image Credit: José Antonio Peñas/Sinc

“Imagine how foolish you would feel […]

Of Alien Life and Intelligence: Angels and Demons (Part 2)

Looking up at the night sky we have mostly imagined other intelligent civilisations in the Universe as being either humanity’s entirely benevolent, wise teachers or its malevolent conquerers. How possible is it to make contact with just such types of civilisations? Image Credit: ESO/B. Tafreshi

“Life, even cellular life, may exist out yonder […]

Of Alien Life and Intelligence: The Limits of Perception (Part 1)

The Very Large Array of radiotelescopes in Socorro, N.M. Radiotelescopes are being used for more than half a century in the search for extraterrestrial intelligence. Is this means of communication also employed by other intelligent civilisations, and, if so, could we understand and perceive their presence? Image courtesy of NRAO/AUI and Photographer Kelly […]
