Abstract Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its
scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to …

The Atacama Large Millimetre/submillimetre Array (ALMA) is currently in the process of
transforming our view of star-forming galaxies in the distant (z≳ 1) universe. Before ALMA …

Terahertz (THz) radiation encompasses a wide spectral range within the electromagnetic
spectrum that extends from microwaves to the far infrared (100 GHz–∼ 30 THz). Within its …

Merging neutron stars offer an excellent laboratory for simultaneously studying strong-field
gravity and matter in extreme environments. We establish the physical association of an …

Hard X-ray (≥ 10 keV) observations of active galactic nuclei (AGNs) can shed light on some
of the most obscured episodes of accretion onto supermassive black holes. The 70-month …

The Λ CDM cosmology passes demanding tests that establish it as a good approximation to
reality. The theory is incomplete, of course, and open issues are being examined in active …

Far-infrared and submillimeter wavelength surveys have now established the important role
of dusty, star-forming galaxies (DSFGs) in the assembly of stellar mass and the evolution of …

The European Space Agency's Planck satellite, dedicated to studying the early Universe
and its subsequent evolution, was launched 14 May 2009 and has been scanning the …

The all sky surveys done by the Palomar Observatory Schmidt, the European Southern
Observatory Schmidt, and the United Kingdom Schmidt, the InfraRed Astronomical Satellite …

Despite the generally hostile nature of the environments involved, chemistry does occur in
space. Molecules are seen in environments that span a wide range of physical and chemical …
