    The XENON1T detector, tucked into an Italian mountainside to search for signs of a mysterious substance in the universe called dark matter, has picked up a new bump in the data that cannot be explained by current models.

    An analysis of this excess signal, led by physicists from the University of Chicago, the University of California, San Diego, and the University of Zurich and vetted by the entire XENON collaboration, suggests that it may be evidence of new physics—or an unexpected radioactive contaminant. The results were announced in a seminar on June 17, 2020.

    Not radio.

    Not amateur radio.

    Interesting to some (such as myself for non-ham purpose), but really is a space.com piece...

    Radio isn't a single-issue subject. It's inherently scientific, and embraces very many disciplines. Indeed, disciplines of the variety you have in mind are an anachronism.

    Anything with a signal is always interesting.. explains at lot of signals out the on the airwaves..

    Please drop the arguments if this is "amateur radio or not" [comments have been removed]

    This article was approved by QRZ site management/ownership staff and its suitability in this forum is not up to debate.

    No further arguments regarding this, please

    Not debating the interest to some.

    Just a point of information: it is not a 'signal'. It is a 'noise' source; they used the wrong word in the news story on science daily...

    Signals have information, noise has none. Some do debate the requirement of information content. In general, engineers require information content to define a signal.

    There are many forms of noise, and oftentimes, a wide bandwidth is a 'requirement' in defining 'noise'.

    My point is that this 'signal' is not an intelligent message but a natural process.

    What we get from this astronomical detection is an unexpected source of noise, that may not be accounted for by known physics.

    That's what makes it interesting.

    BTW the means for detecting the 'particle' are state of the art hardware. Not RF at all, but worth checking out the detectors and the materials used to generate the photons which 'trace' the particle.

    Its done by the particle hitting xenon atoms which then give off light, which is detected by very sensitive light detectors, similar to CCD's.

    Maybe they need to turn the preamp off. :D
