Using the joint Japan Aerospace Exploration Agency (JAXA), European Space Agency (ESA), and NASA X-Ray Imaging and Spectroscopy Mission (XRISM), scientists uncovered a dense but surprisingly slow wind coming from a neutron star. The finding sheds new light on similar winds blowing from material surrounding supermassive black holes.
Another team used NASA’s Chandra X-ray Observatory to study an ancient supermassive black hole growing at extreme rates. The giant might help answer scientific mysteries about the early universe’s most enigmatic objects.
