In the search for extraterrestrial intelligence, astronomers have come across a variety of unusual phenomena in the universe; while natural explanations have been found for them, so far at least, some of these phenomena can be very bizarre. Fast Radio Bursts (FRBs) are one such …

Astronomers are continuing to monitor a nearby red dwarf star after detecting unusual radio signals apparently coming from the star. It is hoped that additional observations will help to determine the source of the signals, which so far haven’t been explained.

The search for evidence of extraterrestrial intelligence is one of the most exciting pursuits in astronomy today. Needless to say, there is a lot of controversy and debate surrounding the topic, partly due to an event which happened in 1977 – the famous “Wow!” signal. The brief but unusual radio transmission was detected only once, and the debate over its origin has continued to this day. Now, a group of astronomers are claiming to have finally solved the mystery. According to their new study just published, the signal came not from aliens, but comets.

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 there somewhere (or any kind of life) has only become more exciting and compelling. When it comes to intelligent extraterrestrials, SETI is a name that has become part of our modern culture, the Search for Extra-Terrestrial Intelligence. SETI focuses on looking for radio and optical signals that could originate from an advanced society, a technique that in itself has generated much debate. After several decades of searching, a definitive signal has yet to be found, but there have been tantalizing possibilities. Unfortunately, none of those have yet panned out as the signal. Now, another interesting radio signal is making the news – could it be the evidence scientists are looking for or is it another dead-end?
There has been a lot of discussion during the past several days regarding a discovery by the Kepler Space Telescope, which, according to some, may be the first evidence for advanced extraterrestrial intelligence, or perhaps just a weird but natural phenomenon instead.
Since the SETI program first began searching for possible alien radio signals a few decades ago, there have been many false alarms but also instances of fleeting signals of interest which disappeared again as quickly as they had appeared. If a potential signal doesn’t repeat …
As the Kepler space telescope begins finding its first Earth-sized exoplanets, with the ultimate goal of finding ones that are actually Earth-like, it would seem natural that the SETI (Search for Extraterrestrial Intelligence) program would take a look at them as well, in the continuing search …
