The far side of the Moon is incredibly different from the Earth-facing side. 66 years later, we know why the Moon's faces are not alike.
Two large Martian rocks with circular drill holes and light-colored dust are shown on a sandy, rocky surface. Part of a rover’s equipment, searching for traces of organics or signs of Mars life, is visible at the bottom of the image.
The red planet, Mars, may once have been teeming with life, just as Earth is today. Finding "organics" on Mars, however, doesn't mean life.
A grayscale image captures the moon's surface, featuring numerous craters of varying sizes. The scene is reminiscent of a lunar Grand Canyon, with a highlighted spot drawing the viewer's attention.
Our Moon is full of craters, basins, and ancient lava flows. But two large lunar Grand Canyons have the same origin: a single, giant impact.
Spacecraft with solar panels orbits Europa, Jupiter's icy moon, with Jupiter visible in the background.
MIT Scientist Jason Soderblom describes how the NASA mission will study the geology and composition of the surface of Jupiter’s water-rich moon and assess its astrobiological potential.
Image of Mimas, one of Saturn's moons, partially illuminated. The large Herschel crater is prominently visible on the right side of the moon's surface.
The existence of another watery world in the outer solar system may offer clues to how such seas form — and hope for another spot to search for life.
Six images of lunar craters including Centra Mare Fecunditatis, Mare Tranquillitatis, Mare Ingenii, Southweast, Schlieter Crater, Highland 1, Highland 2, and Mare Smth.
The recent discovery of a large cave on the Moon highlights the importance of caves not just for future space explorers but astrobiology as well.

From size to mass to density and more, each world in our Solar System is unique. When we compare them, the results are truly shocking.

The Moon is the most likely place for evidence from the dawn of life on Earth to be preserved in cold storage.

Valles Marineris is the Solar System's grandest canyon, many times longer, wider, and deeper than the Grand Canyon. What scarred Mars so?

Contrary to conventional wisdom, matter can escape the center of the Earth.

Mars, the red planet, was a world we knew almost nothing about until our first spacecraft visited it. In just ~50 years, how far we've come!

Like Mars today, Venus used to be a sci-fi superstar. Recent discoveries could re-ignite our interest in Earth’s “evil twin.”

Mercury, Venus, and Mars are all uni-plate planets, and may always have been. Here's what's known about why Earth, uniquely, has plate tectonics.

On Earth, microbial growth is common in lava tubes no matter the location and climate, whether it’s ice-volcano interactions in Iceland or hot, sand-floored lava tubes in Saudi Arabia.
Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.
Recent research suggests that Earth’s magnetic field bounced back just as complex life was starting to emerge on our planet.

Our research on a Martian meteorite provides new clues about early surface conditions on the red planet.
From hellishly hot planets to water worlds, some distant planets are like nothing in our Solar System.
