Hubble Uncovers Concentration of Small Black Holes

Astronomers using the Hubble Space Telescope in their hunt for a massive black hole at the heart of the globular cluster NGC 6397 found something they weren’t expecting: a concentration of smaller black holes lurking there instead. This is a new twist on the search for intermediate-mass black holes. They are the long-sought “missing link” between supermassive black holes and stellar-mass black holes.

How Large Are Neutron Stars?

An interdisciplinary research team has identified new, narrower limits on the radii of neutron stars—close to 11 kilometers. The novel approach combined two sources of information: the first gravitational-wave and electromagnetic observations of a binary neutron-star collision, and modern nuclear-theory calculations of uncertainty. The results suggest that neutron-star black-hole collisions can swallow neutron stars whole.

American Institute of Physics Announces 2020 Science Communication Award Winners

The American Institute of Physics recognizes the winners of the 2020 Science Communication Awards for their topical works on reshaping our world, recognizing forgotten women in science, searching for knowledge, and hunting down black holes. The 2020 winners are Susan Hockfield, Joshua Sokol, Curtis Manley, and Catalyst.

AIP Congratulates 2020 Nobel Prize Winners in Physics

The 2020 Nobel Prize in physics was awarded to Roger Penrose, Reinhard Genzel, and Andrea Ghez, for their work on black holes, described by the Nobel committee as “the darkest secrets in the universe.” To help journalists and the public understand the context of this work, AIP is compiling a Nobel Prize resources page featuring relevant scientific papers and articles, quotes from experts, photos, multimedia, and other resources. The page will be updated throughout the day.
