A rocketship named Dragon breathed new fire into America’s human spaceflight programme on Saturday, carrying two astronauts on a much-anticipated adventure.
Using five years of magnetic field data obtained by NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft, a team of scientists has created the first-ever map of the electric current systems in the Martian induced magnetosphere. Their results appear in the journal Nature Astronomy.
A study reveals the amount of debris likely to hit Earth every year and where
It’s too soon to tell if we’re already in Solar Cycle 25.
The long-sought matter appears to have been hiding in the gaps between galaxies
This galaxy would have once looked a lot like the early Milky Way.
