![]() A high-resolution (R~20,000) setting in the H-band has been designed for accurate determination of stellar abundances such as alpha, light, iron-peak, neutron-capture elements. Therefore, MOONS will provide this crucial follow-up for the Gaia mission and for Galactic surveys with the VISTA telescope (as well as the southern regions observed by Pan-STARRS and UKIDSS), delivering accurate radial velocities, metallicities and chemical abundances for several millions of stars over its lifetime. The Gaia mission is now providing the community with high-precision positional measurements of about one billion stars, with dedicated ground-based surveys ( Gaia-ESO, 4MOST, WEAVE, GALAH) in place or planned to provide the spectroscopy for chemistry and kinematics. MOONS will observe up to 1,000 targets across a 25 arcmin field-of-view in the optical and near-infrared (0.6-1.8 um) simultaneously. My suggestion is to build what you want to build, and whenever you run into a resource wall, double (or whatever you have the resources for) that production. The new observations were carried out with the Long Wavelength Spectrometer, one of four instruments on board ISO. The astronomers searched for hydrogen fluoride molecules within a giant cloud of interstellar gas located near the centre of the Milky Way galaxy. So at the end of the day, Ill need approximately 65.6 million 65,000 carbon to make a polytool. As a result, the need to obtain a large-scale empirical description of the Milky Way has defined the ambitious requirements of large photometric and spectroscopic surveys during the last decade. The discovery was reported in the Astrophysical Journal Letters. As such it is an ideal, and indeed, unique laboratory to investigate the details of the processes behind formation and evolution of a disc galaxy. The study of resolved stellar populations of the Milky Way and other Local Group galaxies can provide us with a fossil record of their chemo-dynamical and star-formation histories over many gigayear timescales. The Milky Way is the only galaxy whose components can all be resolved into individual stars. ![]()
