The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Simulations of quantitative shift in bio-climatic indices in the viticultural areas of Trentino (Italian Alps) by an open source R package

In consideration of the steady entanglements of viticulture with the environmental features – including climate – it is of concern to project which climatic conditions an area is expected to face in a changing climate scenario. A quantitative approach helps in assessing class shift in climate classification; both “generic” climatic and bioclimatic indices were considered in this study, namely: Köppen – Geiger types and subtypes, aridity (6 indices), and “International vine and wine organization” (OIV) classification (10 indices). All indices were easily calculated by an open source R library (ClimClass), which also includes tools for base pre-processing of weather series. Future climate scenarios for this study were obtained using the Regional Climate Model (RCM) COSMO-CLM, employing two IPCC’s greenhouse gas concentrations (RCP 4.5 and RCP 8.5), statistically downscaled to 39 weather stations in Trentino, a region in the Italian Alps. The simulations envisage the new climatic profile of the area, with a shift towards warmer and somewhat drier conditions. While no limitation to wine growing is expected in the lower altitude areas, new climatic suitability is projected for mountain areas, presently devoted to other soil uses. The latter analysis was the result of a calibration of a thermal requirement index to the present soil use condition in the regio

A measurement of the cosmological mass density from clustering in the 2dF Galaxy Redshift Survey

The large-scale structure in the distribution of galaxies is thought to arise from the gravitational instability of small fluctuations in the initial density field of the Universe. A key test of this hypothesis is that forming superclusters of galaxies should generate a systematic infall of other galaxies. This would be evident in the pattern of recessional velocities, causing an anisotropy in the inferred spatial clustering of galaxies. Here we report a precise measurement of this clustering, using the redshifts of more than 141,000 galaxies from the two-degree-field (2dF) galaxy redshift survey. We determine the parameter = 0.6/b = 0.43 0.07, where is the total mass-density parameter of the Universe and b is a measure of the 'bias' of the luminous galaxies in the survey. (Bias is the difference between the clustering of visible galaxies and of the total mass, most of which is dark.) Combined with the anisotropy of the cosmic microwave background, our results favour a low-density Universe with 0.3
