Features

Great comets

Lots of comets come and go, but only a favored few have all the magic ingredients-the five key properties, to be precise - that make a comet great.

Opportunity at Meridiani

NASA's second Mars rover, Opportunity, landed at a site in Meridiani Planum that turned out to have been "drenched in water," as one scientist put it. It was once so wet and warm there as to be habitable.

A new vision for space

U.S. president George W. Bush announced the boldest initiative in space exploration since Apollo: building a Moon base as a stepping-stone to Mars. Can it be done? Take a look at what's in store.

A tale of two comets

Comets C/2002 T7 (LINEAR) and C/2001 Q4 (NEAT) should be at their brightest in May, providing wonderful views to observers around the globe.

All-sky fireball network

An interconnected group of all-sky cameras watches the sky 24 hours a day. The reason? The operators of this system are tracking brilliant meteors in the hope of actually recovering meteorites.

Robotic observing

Scour the sky while fast asleep. Too good to be true? Tenagra Observatories' computer-controlled telescopes let you catch supernovae while catching some shut-eye.

Orion's Atlas 8

A classic telescope design, a drive motor that follows the stars across the sky, and all the accessories you need to observe celestial objects make the new 8-inch reflector from Orion a winner.
