XRISM could tell the distribution of matter around this black hole over a radius of about 0.001 light-years to 0.1 light-years. That’s roughly the same as the Sun-Uranus distance then up to 100 ...

The X-ray telescope, also known as XRISM, is operated by the Japan Aerospace Exploration Agency (JAXA) with participation from the European Space Agency (ESA). Its first observations captured the ...

If JAXA does unjam its door, Chandra will be an important tool to follow up XRISM's observations. Meanwhile, the ghosts of Suzaku and Hitomi will linger until the next attempt at opening the door.

NASA and JAXA plan to operate an instrument on an X-ray astronomy satellite as-is for at least 18 months despite an issue affecting one of its instruments.
