Astrophysicists and their experiments normally look up, not down. IceCube is an exception. Here the density profile of the Earth is measured using neutrinos.
Nearby Super-Jupiters with very tight orbits produce gravitational waves that will be detectable by space-based gravitational wave detectors.
The first compelling association of an electromagnetic counterpart with an astrophysical neutrino since SN 1987A.
A laboratory astrophysics experiment calls into question the proposed dark matter origin of an unidentified spectral line at 3.5 keV
Hints of a theory beyond General Relativity could lie in the shape of a black hole’s shadow. An Earth-sized telescope will allow us to resolve these shadows for the first time.
