Astronomy Picture Of the Day (APOD)
NGC 7023: The Iris Nebula
4.11.2004
Like delicate cosmic petals, these clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheus. Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers.
A Time Lapse Lunar Eclipse
3.11.2004
During last week's lunar eclipse, our Moon appeared to disappear. As the Earth moved between the Moon and the Sun, the Earth's shadow fell on the moon, making it quite dark.
Storm Alley on Saturn
2.11.2004
What causes storms on Saturn? To help find out, scientists commanded the robot Cassini spacecraft now orbiting Saturn to inspect a circulating band of clouds nicknamed "Storm Alley." This westwardly moving cloud ring...
Spooky Star Forming Region DR 6
1.11.2004
How could stars form such a spooky and familiar shape as a human skull? First, the complex process of star formation creates nebulas of many shapes and sizes -- it is human perception that identifies the skull shape.
Halloween and the Ghost Head Nebula
31.10.2004
Halloween's origin is ancient and astronomical. Since the fifth century BC, Halloween has been celebrated as a cross-quarter day, a day halfway between an equinox (equal day / equal night) and a solstice (minimum day / maximum night in the northern hemisphere). With our modern calendar, however, the real cross-quarter day will occur next week.
Pumpkin Moon
30.10.2004
Does this look familiar? Red and orange hues haunting the face of the Moon might remind you of the October 27th total lunar eclipse, but the picture is actually a montage of images from a similar lunar spectacle in May of 2003.
Red Moon Triple
29.10.2004
Some thought of baseball and some thought of Halloween during October 27th's widely viewed total lunar eclipse. Sliding through Earth's shadow, the Moon turned haunting shades of red and orange during the eclipse's total phase.
Tantalizing Titan
28.10.2004
Normally hidden by a thick, hazy atmosphere, tantalizing features on Titan's surface appear in this false-color view. The image was recorded as the Cassini spacecraft approached its first close flyby of Saturn's smog-shrouded moon on October 26.
Total Lunar Eclipse Tonight
27.10.2004
Go outside tonight and see the total lunar eclipse. Tonight's eclipse is easy and convenient for much of the world to see. Anyone who can spot a full Moon -- even during the day -- can see it fade out as the Earth's shadow engulfs it.
Titan Through the Haze
26.10.2004
What are these surface features on Titan? This planet-sized moon of Saturn had much of its south polar surface imaged during an initial flyby by the Saturn-orbiting Cassini spacecraft back in early July.
