Solar System’s First Interstellar Visitor Dazzles Scientists

Artist's concept of interstellar asteroid 1I/2017 U1

New data reveal first detected interstellar object to be a rocky, and up to one-quarter mile (400 meters) long and highly-elongated-perhaps 10 times as long as it is wide.



NASA Links Port-City Sea Levels to Regional Ice Melt

The contribution of melting ice in Greenland

A new NASA tool that links changes in sea level in 293 global port cities to specific regions of melting land ice may help coastal planners prepare for future rising seas.



Recurring Martian Streaks: Flowing Sand, Not Water?
