Like humanity, alien civilizations need to harvest energy. But how to power your civilization, if the energy of a star is not enough? Today’s authors discuss a fascinating prospect: Harvesting the energy of black holes with Dyson spheres.
Today’s paper investigates a mysterious stellar explosion that resulted when a black hole or a neutron star crashed into a star.
In the latest of our #UndergradResearch series, read about the work by Beryl Hovis-Afflerbach on the environments in which binary black holes originate!
Supermassive black holes have a really nasty reputation for rendering galaxies uninhabitable, but this perception may be misguided. It’s possible that the radiation these vast beasts release while feasting could bring forth a bounty for life as we know it. Could organisms subsist on the light of an AGN sun?
A Milky way star cluster seems to contain more than the name suggests. How do astronomers find black holes hiding amongst stars?
How can tides help us find hidden compact companions and yield detailed physics on stellar binaries?
