The new dataset shows clear evidence of a background of gravitational waves that comes from massive objects in other galaxies moving through spacetime.
Astronomers are finding that different types of galaxies are more prevalent at different times during the history of the Universe. Hot DOG galaxies, or “hot dust-obscured” galaxies, are a special type of quasar.
Ground-based astronomers already have to combat light pollution, atmospheric effects, and tight scheduling for telescope time on high-demand telescopes around the world. The reality of Starlink now brings a new problem.
