Where Martian Dust Comes From

Where Martian dust comes from?

The dust that coats much of the surface of Mars originates largely from a single thousand-kilometer-long geological formation near the Red Planet's equator, scientists...
Stolen electrons create unusual aurora on Mars

Stolen electrons create unusual aurora on Mars

Auroras appear on Earth as ghostly displays of colorful light in the night sky, usually near the poles. Our rocky neighbor Mars has auroras too,...
Mars’ crustal evolution does not follow Earth’s formula, says Cornell study

Mars’ crustal evolution does not follow Earth’s formula, says Cornell study

Mars, strewn with rocks and pocked by craters, may not have an Earth-like, continental crust. Instead, a Cornell scientist poses an alternative theory: Crystalized magma...
New research raises hopes for finding life on Mars, Pluto and icy moons

New research raises hopes for finding life on Mars, Pluto and icy moons

Since the 1970s, when the Voyager probes captured images of Europa’s icy surface, scientists have suspected that life could exist in interior oceans of...

NASA’s storm chasers on Mars search for dusty secrets

Storm chasing takes luck and patience on Earth -- and even more so on Mars. For scientists watching the Red Planet from NASA's orbiters, the...
Did heavy rain give Mars its deep valleys

Did heavy rain give Mars its deep valleys

Heavy rainfall may have formed the valley networks on Mars that bear a strong resemblance to those in arid landscapes here on Earth, according...
When life might have existed on Mars Meteorite 'Black Beauty' offers new clues

When life might have existed on Mars? Meteorite ‘Black Beauty’ offers new clues

The early surface of Mars consisting of a liquid magma ocean crystallized extremely rapidly, just 20 million years after the formation of the solar...
Mars dust storm may lead to new weather discoveries

Mars dust storm could lead to new weather discoveries

Mars is experiencing an estimated 15.8-million-square-mile dust storm, roughly the size of North and South America. This storm may not be good news for the...
These two exoplanets are really like Earth

These two exoplanets are really like Earth

Research into spin dynamics suggests they have regular seasons and stable climates Two exoplanets thought to be similar to Earth apparently are, at least when...
Mars valleys went through heavy rain and erosion

Mars valleys went through heavy rain and erosion

Astonishingly similar: The valley networks of Mars bear a strong resemblance to those found in arid landscapes on Earth. Researchers have been able to...
