'On our way to Mars': NASA rover will look for signs of life

The biggest, most sophisticated Mars rover ever built—a car-size vehicle bristling with cameras, microphones, drills and lasers—blasted off for the red planet Thursday as part of an ambitious, long-range project to bring ...

Astrophysicists observe long-theorized quantum phenomena

At the heart of every white dwarf star—the dense stellar object that remains after a star has burned away its fuel reserve of gases as it nears the end of its life cycle—lies a quantum conundrum: as white dwarfs add mass, ...

ALMA finds possible sign of neutron star in supernova 1987A

Two teams of astronomers have made a compelling case in the 33-year-old mystery surrounding Supernova 1987A. Based on observations of the Atacama Large Millimeter/submillimeter Array (ALMA) and a theoretical follow-up study, ...
