    This threw me at first. There was an NASA X-ray imaging telescope in the late 70s/early 80s called Einstein:

    But this is a new Chinese instrument, also an X-ray telescope, also called Einstein:

      Pedantically, it's Einstein Probe (EP), not Einstein. Confusingly, in Chinese it has another name, Tianguan, commemorating the observation of the supernova which created the Crab Nebula.

    This is not very newsworthy, stellar flares are common and known to emit X-rays.

    If measured the way we measure solar flares (M1, X1 etc) what would this one be rated as?

    For a second I was really confused about what Epstein had to do with x-rays

      SAME, I thought there was a bit flip in the files or something.
