We present Near-Infrared spectra of 11 objects in the Chaldaea asteroid family obtained with NASA's InfraRed Telescope Facility (IRTF) and the Telescopio Nazionale Galileo (TNG) between January 2017 and July 2019. From our sample we conclude that Chaldaea objects have red slopes and positive curvature, and are essentially identical to each other

The population of near-Earth objects (NEOs) shows a large variety of physical and dynamical properties. Their study is relevant for the science of planetary systems and for practical reasons regarding space exploration and long-term probability of impact with the Earth. We report the spectral and spectro-photometric data of 135 NEOs. These are

In the Sun, the properties of acoustic modes are sensitive to changes in the magnetic activity. In particular, mode frequencies are observed to increase with increasing activity level. Thanks to CoRoT and Kepler, such variations have been found in other solar-type stars and encode information on the activity-related changes in their interiors. Thus

The small size of the SETI workforce is a major problem for NASA and the search for life elsewhere in the universe. The Astro2020 Decadal should address this issue by making nurturing the field an explicit priority for the next decade.

This white paper presents the case for SDSS-V. SDSS-V is an unprecedented all-sky spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way galaxy, trace the emergence of the chemical elements, reveal the inner workings of galaxies and their stars, and investigate the origin of planets.
