From Black Hole Mergers to the Wow! Signal: A Snapshot of Modern Space Discoveries and SETI
To the point
Space science today spans violent cosmic events and icy interstellar visitors, including many black hole and neutron star mergers seen via gravitational waves, the interstellar comet 3I/ATLAS shedding material but not a spacecraft, a star growing into a hypergiant on the path to a possible supernova, SETI listening for signals with the Allen Telescope Array, and unresolved hints like the Wow! signal and the 2015 HD 164595 signal, all amid ongoing exoplanet discoveries and space missions shaping the near term, with perspectives from Seth Shostak and Jerry Ehman.
