Moon Zoom
Imagine riding a magic carpet around the moon and being able to zoom down to any point or appear magically at any location. NASA has developed software that allows you to interactively browse three-dimensional images of the moon, based on data obtained by the Clementine spacecraft. These Web pages provide information about downloading the software, […]

Protecting Earth: Gravitational tractor could lure asteroids off course
Relying solely on the tug of gravity, a proposed spacecraft could divert an asteroid on a collision course with Earth.

New Partners: Hubble finds more moons around Pluto
Astronomers using the Hubble Space Telescope have spied two tiny moons orbiting Pluto, giving this planet a total of three satellites.

Spooky Sounds of Saturn
For Hallowe’en, tune in to eerie, bizarre sounds from the Saturnian system. These NASA Jet Propulsion Lab Web pages provide sound files based on magnetometer data from Cassini spacecraft observations of Saturn’s moon Enceladus, radar echoes from Titan’s surface, Saturn’s radio emissions, and more.

Shoreline for Titan?
New radar images of Saturn's smog-shrouded moon Titan show evidence of a shoreline cutting across the moon's southern hemisphere.
- Planetary Science
’10th planet’ has a partner
The so-called 10th planet, an object larger than Pluto that ranks as the most distant body known in the solar system, has a moon.
- Planetary Science
Mining the moon
New ultraviolet images of the moon help identify the presence of ilmenite, a titanium oxide whose elemental constituents may be a valuable resource for sustaining humans as they explore the lunar surface.

Mission to the outer limits
NASA's New Horizons spacecraft has taken up temporary residence at the Kennedy Space Center, where engineers are doing final testing before the craft begins its 9-year voyage to the outer solar system.

Saturnian sponge
The first close-up portrait of Saturn's icy moon Hyperion reveals a spongy-looking surface unlike that of any other known moon.

What whacked the inner solar system?
Planetary scientists have determined that the cavalcade of space debris that hammered the inner solar system for the first 700 million years of its existence were main-belt asteroids, not comets.
- Astronomy
Crisis in the Cosmos?
Baby galaxies that hail from the early history of the cosmos but are full of old stars and are nearly as massive as the Milky Way is today may challenge the standard theory of galaxy formation.

Cosmic Ray Font: Supernova remnants rev up ions
High-resolution X-ray images of the Tycho supernova remnant offer new evidence that supernova shock waves generate most cosmic rays that bombard Earth.
