For example, when a satellite detects an exploding star from 50 billion light years away, that's already news. Signals from distant galaxies are by definition newly received and noteworthy information. They're sure as shit more important than failed American Idol contestants exchanging genetic information, but those guys manage to get headlines without any implications of creating alien life. If news services need to add aliens to make the entire universe interesting, surely they should have to suggest Illuminati involvement in every sports score and include illegal human cloning accusations in every article about The Great British Bake Off.
Plutonians collect contestants for the new series on Channel Zorqlax.
If you ever find an "Is it aliens?" article that doesn't include at least one fictional reference, please check that you're not a unicorn, because popular science thinks people care a lot more about the "popular" than the "science." So if the text doesn't describe major scientific advances as if they're a Star Trek spinoff, the art will be of alien monsters or a flying saucer. Remember, a picture is worth a thousand words, and this is "We think you are an idiot who will not read anything above a fourth-grade level without colorful imaginary bullshit" times 50. If two black holes collide and we're smart enough to sense the space fireworks, we don't need the inclusion of E.T. to know that's awesome.
The problem is the mismatch between the news cycle and scientific progress, because those are on opposite ends of the spectrum. Science requires ideas, theories, experiment, rigorous analysis and peer review, and the accumulation of confirmation. That takes lots of time. Journalists require "I heard that someone heard it, maybe, and also I have a deadline to meet."
This one by ... New Scientist? Really? Is the concept of "scientist" new to them?
The story above ramps up the ridiculous level by adding that this find has "baffled scientists." They're not baffled! They just discovered it, are reporting it, and are still working out what it is. A plumber isn't "baffled" when they've just found the blockage in your toilet; they're still working on it, and eventually they will figure it out. Unless you've been passing crap even worse than these articles.
