New measurement method promises spectacular insights into the interior of planets

New observations reveal that Mars could still be volcanically active, raising the possibility for habitable conditions below the surface of Mars in recent history

New study suggests that the Martian subsurface might be a good place to look for possible present-day life on the Red Planet

Mars had dry and wet eras and dried up for good 3 billion years ago

New findings could be critical in understanding the climate of early Mars

These features, which are not found on Earth, are believed to be carved into the Martian surface by dry ice changing directly from solid to gas in the spring

Challenging assumptions about the possibility of modern life on Mars

Researchers have come up with a theory about what is causing landslides on the surface of Mars

The high schoolers turned scientists published their findings this week, thanks to a research mentorship program at the Center for Astrophysics; Harvard and Smithsonian

The raging megaflood—likely touched off by the heat of a meteoritic impact—set up gigantic ripples that are tell-tale geologic structures familiar to Earth scientists
