Using NASA's Swift telescope and the Neutron star Interior Composition Explorer (NICER) instrument onboard the International Space Station, Indian astronomers have inspected timing and spectral properties of an X-ray transient ...
Roughly a half-century ago, astronomers realized that the powerful radio source coming from the center of our galaxy (Sagitarrius A*) was a "monster" black hole. Since then, they have found that supermassive black holes (SMBHs) ...
