| PSRD: Timeline of Martian Volcanism (ppt) | The work confirms previous findings by others that volcanism was continuous throughout Martian geologic history until about one to two hundred million years ago, the final volcanic events were not synchronous across the planet, and the latest large-scale caldera activity ended about 150 million years ago in the Tharsis province. |
Images
| Evolution of Our Solar System | This series of illustrations are part of an exhibit depicting the formation and evolution of the planets and moons in our solar system. | | Planetary Demolition Derby (Artist Concept) | This artist's concept shows a celestial body about the size of our moon slamming at great speed into a body the size of Mercury. NASA's Spitzer Space Telescope found evidence that a high-speed collision of this sort occurred a few thousand years ago around a young star, called HD 172555, still in the early stages of planet formation. | | Gas Giants Form Quickly (Artist Concept) | This is an artist's concept of a hypothetical 10-million-year-old star system. The bright blur at the center is a star much like our sun. The other orb in the image is a gas-giant planet like Jupiter. Wisps of white throughout the image represent traces of gas. Astronomers using NASA's Spitzer Space Telescope have found evidence showing that gas-giant planets either form within the first 10 million years of a sun-like star's life, or not at all. |

| Clues About Mars Evolution Revealed | Lapen and his colleagues' data showed that the true age of Mars meteorite ALH84001 is 4.091 billion years old, about 400 million years younger than earlier age estimates. They concluded that this stone formed during an important time when Mars was wet and had a magnetic field, conditions that are favorable for the development of simple life. | | The Early Earth and Plate Tectonics | The Earth is formed by accretion of spatial particulates and large masses and eventually forms an outer crust. Video follows with speculation of early plates and land masses and their movement through time. | | Evolution of the Moon | This video covers the Moon's geologic history, in a variety of formats,
including 3D, and with and without narration. |
Podcasts
| Tracing Planetary Atmospheric Evolution Using Isotopes from Life: Part 1 and Part 2 | This 365 Days Of Astronomy podcast is with Dr. Naomi Levin about paleo-climate research, the study of how Earth's atmosphere and climate have changed since its formation, and the clues plant and animal fossils leave us that reveal these ancient climate patterns. |
Animation
| Mars Atmosphere Loss | This video illustration shows how Mars may have lost its atmosphere to the solar wind after the Red Planet's magnetic field died. | | Solar-System Evolution: The Nice Model | This video of the Nice Model shows how the orbits of the outer gaseous planets of our solar system might have evolved. It also explains why and how the late heavy bombardement might have taken place. |
Interactives
| Gas Retention Plot | This interactive explores some of the elements that go into the retention or loss of an atmosphere by a planet. |
Networks
| Solar System Ambassadors | The Solar System Ambassadors is a nation-wide network of volunteers who are trained to communicate the excitement of NASA's space exploration missions and recent discoveries to people in their local communities. | | Museum Alliance | The Museum Alliance is a network of museums, science centers, planetariums, observatories, parks, NASA Visitor Centers, nature centers, zoos, and aquariums that bring current NASA science and technology to their visitors through professional development of their staff and access to NASA staff, content and materials. | |
Night Sky Network | This site can connect you to amateur astronomy clubs, events, a night sky planner, and more. |
