Chinese astronomers have found evidence of a "dark" galaxy: 98% dark matter, 2% hydrogen, and almost no stars at all.
It showed up in their radio telescope, but when they looked for the light from its stars they saw...nothing.

It is really nice that despite any tensions between the political side of different countries, the science community can just work together and achieve great things.
@zleap I am constantly grateful that curious people exist everywhere, in all cultures & political settings.
