How Habitable is Titan? NASA is Sending the Titan Dragonfly Helicopter to Find Out

How Habitable is Titan? NASA is Sending the Titan Dragonfly Helicopter to Find Out

There are few places in the Solar System which are as fascinating as Saturn’s moon Titan. It’s a world with a thicker atmosphere than Earth. Where it’s so cold that it rains ammonia, forming lakes, rivers and seas. Where water ice forms mountains. 

What Does a Marsquake Look Like?

What Does a Marsquake Look Like?

Southern California got all shook up after a set of recent quakes. But Earth isn't the only place that experiences quakes: Both the Moon and Mars have them as well. NASA sent the first seismometer to the Moon 50 years ago, during the Apollo 11 mission; the agency's InSight lander brought the first seismometer to Mars in late 2018, and it's called the Seismic Experiment for Interior Structure (SEIS).

Earth has a Water Cycle. Mars has a Dust Cycle

Earth has a Water Cycle. Mars has a Dust Cycle

To say there are some myths circulating about Martian dust storms would be an understatement. Mars is known for its globe-encircling dust storms, the likes of which are seen nowhere else. Science fiction writers and Hollywood movies often make the dust storms out to be more dangerous than they really are. In “The Martian,” a powerful dust storm destroys equipment, strands Matt Damon on Mars, and forces him into a brutal struggle for survival.

Table Salt Compound Spotted on Europa

Table Salt Compound Spotted on Europa

A familiar ingredient has been hiding in plain sight on the surface of Jupiter's moon Europa. Using a visible-light spectral analysis, planetary scientists at Caltech and NASA's Jet Propulsion Laboratory in Pasadena, California, have discovered that the yellow color visible on portions of the surface of Europa is actually sodium chloride, a compound known on Earth as table salt, which is also the principal component of sea salt.

Theory proposes that Venus could have been habitable, but a large ocean slowed down its rotation, killing it

Theory proposes that Venus could have been habitable, but a large ocean slowed down its rotation, killing it

There’s no sense in sugar-coating it – Venus is a hellish place! It is the hottest planet in the Solar System, with atmospheric temperatures that are hot enough to melt lead. The air is also a toxic plume, composed predominantly of carbon dioxide and sulfuric acid rain clouds. And yet, scientists theorize that Venus was once a much different place, with a cooler atmosphere and liquid oceans on its surface.

NASA's Juno Finds Changes in Jupiter's Magnetic Field

NASA's Juno Finds Changes in Jupiter's Magnetic Field

NASA's Juno mission to Jupiter made the first definitive detection beyond our world of an internal magnetic field that changes over time, a phenomenon called secular variation. Juno determined the gas giant's secular variation is most likely driven by the planet's deep atmospheric winds.

Why This Martian Full Moon Looks Like Candy

Why This Martian Full Moon Looks Like Candy

For the first time, NASA's Mars Odyssey orbiter has caught the Martian moon Phobos during a full moon phase. Each color in this new image represents a temperature range detected by Odyssey's infrared camera, which has been studying the Martian moon since September of 2017. Looking like a rainbow-colored jawbreaker, these latest observations could help scientists understand what materials make up Phobos, the larger of Mars' two moons.

A Strange Ice Feature Wraps Halfway Around Titan

A Strange Ice Feature Wraps Halfway Around Titan

For people interested in all things beyond Earth, the words methane and Titan go hand in hand. After all, Titan is the only other world in our Solar System where liquid flows over the surface. While trying to understand Titan’s methane cycle, scientists have discovered something else: a bizarre methane ice feature that wraps halfway around Saturn’s largest moon.

Curiosity has Finally Sampled a Clay-Rich Region on Mars

Curiosity has Finally Sampled a Clay-Rich Region on Mars

It’s hard to believe that MSL Curiosity has been on Mars for almost seven years. But it has, and during that time, the rover has explored Gale Crater and Mt. Sharp, the central peak inside the crater. And while it has used its drill multiple times to take rock samples, this is the first sample it’s gathered from the so-called ‘clay unit.’
