The scientific data left in the wake of the horrific December 26, 2004 tsunami is proving invaluable to better prepare for future events. Meet the researchers at the crest of this relatively young science. Featured are the geologists, seismologists, and computer modelers of the U.S. Pacific Northwest, an area replete with geological and anthropological evidence of past tsunamis. Learn how the region is preparing for its inevitable next wave.
Since its discovery in 1930, we've looked at Pluto as our solar system's ninth planet. But residing in the icy realm of the outer solar system, where the sun's brightness is less than 1/1000 of the brightness here on Earth, Pluto is nothing like the other planets of our solar system. It differs tremendously from the gas giants Jupiter, Saturn, Uranus, and Neptune, but does not resemble the rocky terrestrial worlds Mercury, Venus, Earth, and Mars.
The peaceful glow of the moonlight in our sky belies a violent history. Evidence suggests that the Moon formed when a Mars-sized object collided with the young Earth, and detailed computer models show us how such an impact could form our lunar companion in just one month.

On cloudless, moonless nights, the stars are so bright over the remote village of Sutherland, South Africa, that a person can walk by starlight alone. Learn more about the village’s Southern African Large Telescope (SALT).
Scientists have been studying brown dwarfs, or failed stars, for nearly a century. What have they learned? And what answers are they still seeking about these objects stuck somewhere between stars and planets?
Two teams working independently in 1998 came to the same conclusion: An invisible force, one that seems to act opposite gravity, is separating the matter in space at an increasing pace. Find out more about their “jaw-dropping” discovery.
In 2004, news of Asteroid MN4 hit the blogosphere: "So, in summary, there's a 1-in-233 chance of the worst disaster in recorded history happening on April 13, 2029, and a 232-in-233 chance of nothing happening." Take a closer, scientific look.
Given the potential for asteroids to literally and figuratively impact life on Earth in a profound way, asteroids have been quite sought after since the first and largest one, Ceres, was discovered in 1801. Learn more.
