Astronomy Picture Of the Day (APOD)
Name This Martian Robot
26.11.2002
NASA will launch two robots to Mars next year and you can help name them. The Mars Exploration Rovers are scheduled for launch on or near this coming June, when Mars and Earth are relatively close in their orbits.
The Earths Magnetic Field
25.11.2002
Why does the Earth have a magnetic field? The electrical conductivity of the molten plasma of the Earth's core should be able to damp the current magnetic field in only thousands of years. Yet our five billion year old Earth clearly causes magnets to point to (defined) north.
Hubble Floats Free
24.11.2002
Why put observatories in space? Most telescopes are on the ground. On the ground, you can deploy a heavier telescope and fix it more easily. The trouble is that Earth-bound telescopes must look through the Earth's atmosphere.
Mare Orientale
23.11.2002
Like a target ring bull's-eye, the Mare Orientale is one of the most striking large scale lunar features. Located on the Moon's extreme western edge, this impact basin is unfortunately difficult to see from an earthbound perspective.
Full Moon, Lake, and Leonids Indeed
22.11.2002
Full of itself moon - EVERYONE SHOULD LOOK AT ME. What's 33 years? And for those who need a story ... photographer Blake Suddeth took over a hundred digital pictures early Tuesday morning in order...
Starburst Galaxy M94
21.11.2002
What could cause the center of M94 to be so bright? Spiral galaxy M94 has a ring of newly formed stars surrounding its nucleus, giving it not only an unusual appearance but also a strong interior glow.
Leonids vs The Moon
20.11.2002
Beautiful and bright, the 2002 Leonid meteors battled against glaring moonlight. This winning example, from Tuesday morning skies above Laughlin, Nevada, USA, finds an undaunted Leonid streaking between the familiar constellation of Orion (left) and an overexposed full Moon.
Leonid Meteors in 2002
19.11.2002
All during today, APOD will be posting the best images of the Leonid Meteor Shower as seen by the wide-angle digital cameras perched around the world as part of the Night Sky Live (NSL) Project. The main APOD site will be updated several times with topical information and new images.
The Car, the Hole, and the Peekskill Meteorite
18.11.2002
The Peekskill meteor of 1992 was captured on 16 independent videos and then struck a car. Documented as brighter than the full Moon, the spectacular fireball crossed parts of several US states during its 40 seconds of glory before landing in Peekskill, New York.
Leonids from Leo
17.11.2002
Is Leo leaking? Leo, the famous sky constellation visible on the left of the above all-sky photograph, appears to be the source of all the meteors seen in last year's Leonids Meteor Shower.
