Signs of life: New field guide aids astronomers’ search
ITHACA, N.Y. – A Cornell University senior has come up with a way to discern life on exoplanets loitering in other cosmic neighborhoods: a spectral field guide. Zifan Lin has developed high-resolution spectral models and scenarios for two exoplanets that…
First giant planet around white dwarf found
ESO observations indicate the Neptune-like exoplanet is evaporating
NRL, NASA combine to produce sun imagery with unprecedented clarity
WASHINGTON — Early returns from the U.S. Naval Research Laboratory’s camera on NASA’s latest mission to study the Sun’s corona revealed on Dec. 4 a star more complex than ever imagined. NRL’s Wide-field Imager for Parker Solar Probe, or WISPR,…
