The earth's diameter is 12,756.3 km and its revolution period is 1 year. You probably knew the last fact, but most likely not the first. The Web site Absolutely Astronomy can provide this and a large amount of other facts about planets, moons, stars, constellations, messier objects, nebulas, and galaxies. Visitors can browse via the pull-down menus or search by a particular question. The basic...

Astronomy Online

Ricky Leon Murphy decided to create this website when he was working towards a master’s degree in astronomy, and he still keeps it updated regularly, along with the assistance of his wife, Chanthirar. The site has been the recipient of several awards over the past few years, and visitors looking for basic and accessible information about the world of astronomy will not be disappointed. Near the...
Galileo Spacecraft Finds Thin Atmosphere in Callisto

The Galileo Spacecraft "has detected a thin carbon dioxide atmosphere on Jupiter's moon Callisto, and has confirmed the existence of carbon dioxide on Callisto's surface." This epiphany is very exciting because it means that all of Jupiter's Galilean moons, Callisto, Europa, Io, and Ganymede, have some form of atmosphere. This site is a news release from the Jet Propulsion Laboratory.

One tool to help provide that perspective is this wonderful visualization created by Josh Worth, a graphic and web designer based in Los Angeles. As its title suggests, this project is "a tediously accurate scale...
Lunar Data Support Idea that Collision Split Earth, Moon

Scientists at the 30th Lunar and Planetary Science Conference held March 15-19, 1999 in Houston, Texas, have presented support for the theory that the "bulk of the Moon was ripped away from the early Earth when an object the size of Mars collided with the Earth." Analysis of data collected from the National Aeronautics and Space Administration's (NASA) Lunar Prospector spacecraft has supported...
Mathilde Encounter: Near Earth Asteroid Rendezvous

In one of the most successful flybys of all time, the NEAR spacecraft passed within 1200 km of asteroid 253 Mathilde on June 27. Johns Hopkins University Applied Physics Laboratory has created a website to document this event. The site contains information on the NEAR mission objectives, science goals, and Mathilde itself. It also features images of the asteroid, a flyby simulation, and an MPEG...
