Color flashing stars could be evidence of ET

Could anomalous color changes in distant stars be evidence of ET ? Image Credit: NASA/ESA
Two Canadian astronomers have found possible signs that an alien civilization is trying to communicate.
In a recent study, Ermanno F. Borra and Eric Trottier discovered that 234 stars out of the 2.5 million captured by the Sloan Digital Sky Survey appeared to exhibit signs of abnormal spectral modulation.

What the pair found most interesting about these tiny, rapid changes in color was the fact that they seemed to be occurring in a repeating pattern that was identical across several of the stars.

Their paper speculated that these anomalous color changes could have an intelligent source.

"We find that the detected signals have exactly the shape of an ETI signal predicted in the previous publication and are therefore in agreement with this hypothesis," they wrote.

"The fact that they are only found in a very small fraction of stars within a narrow spectral range centred near the spectral type of the sun is also in agreement with the ETI hypothesis."

Not everyone however is convinced that the phenomenon has anything to do with aliens.

"The researchers claim to see the same tiny pattern appearing in hundreds of stars which is more likely to be the same mistake in their analysis, not a sign that all aliens are communicating the same way," said astrophysicist Dr Alan Duffy of Swinburne University.

"A detection of alien life would be so extraordinary that to claim it requires extraordinary evidence and several teams and telescopes confirming it."

"This work doesn't even come close to being able to make that claim."

Most of them are probably easily to disprove false positive, but maybe a few of them will turn out to be it.

like Shostak states the very fact the signals are so similar pretty much crunches the idea of et's. What would be the odds of over 200 distinct societies emitting the same signal ?  unless of course its some galactic federation of planets which would truly and utterly be incredibly fantastic wouldn't it? ..( and then I woke up.. )  it would be amazing to be alive should a discovery like this finally be realized. I mean just to witness the implications on a global would the population handle it?. its hard to predict. Many people are so entrenched in there belief systems something lik... [More]

This -- "This work doesn't even come close to being able to make that claim."  C'mon people.

Ok so let me see if i get this. The claim is that a few hundred "stars" emit a pattern of different colors. a possible Morse code like signal. Out of all the stars out there we pick up this signal, and so this is not evidence, instead false data, dont get excited. Well are we not doing almost the same thing except its radio not visible signal. If we had the ability to send visual signals wouldn't we do it in as many as possible, a couple hundred isn't that many and could seem possible depending on scale of species. Time will tell but to me it sure sounds promising.

I've looked up in the sky a few nights and seen what I would consider 'colour flashing' stars. Neat to look at, but never thought it was anything but a natural thing.

Seeing is believing aka "Now you see me". More proof is needed to come to this conclusion

its not just flashing of color but a pattern of that flashing is what makes it potentially not a natural phenomenon.
