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:

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
