Astronomers on Monday made a “big” announcement about exoplanets, and it is big—literally. Another new world has been discovered, which is quite routine now these days, but this one is different, and unexpected: a planet which is more than twice as large [...]

NASA Gives ‘GO’ to Start Construction of InSight 2016 Lander to Elucidate Mars Core

NASA’s Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport (InSight) mission will pierce beneath the Martian surface to study its interior. Insight will hammer the deepest ever hole into the Red Planet to elucidate clues to the Martian core and how Earth-like planets formed. Launch is scheduled for March 2016. Credit: NASA
