Did a gamma-ray burst initiate the late Ordovician mass extinction?
A. Melott, B. Lieberman, C. Laird +6
Gamma-ray bursts (hereafter GRB) produce a flux of radiation detectable across the observable Universe, and at least some of them are associated with galaxies. A GRB within our own…
Dangerous human-made interference with climate: A GISS modelE study
J. Hansen, M. Sato, R. Ruedy +44
We investigate the issue of "dangerous human-made interference with climate" using simulations with GISS modelE driven by measured or estimated forcings for 1880-2003 and extended…
The Pluto system: Initial results from its exploration by New Horizons
S. A. Stern, F. Bagenal, K. Ennico +148
The Pluto system was recently explored by NASA's New Horizons spacecraft, making closest approach on 14 July 2015. Pluto's surface displays diverse landforms, terrain ages, albedos…
Life Beyond the Solar System: Space Weather and Its Impact on Habitable Worlds
V. S. Airapetian, W. C. Danchi, C. F. Dong +33
The search of life in the Universe is a fundamental problem of astrobiology and a major priority for NASA. A key area of major progress since the NASA Astrobiology Strategy 2015 (N…
Climate simulations for 1880-2003 with GISS modelE
J. Hansen, M. Sato, R. Ruedy +44
We carry out climate simulations for 1880-2003 with GISS modelE driven by ten measured or estimated climate forcings. An ensemble of climate model runs is carried out for each forc…
