Astronomy Picture Of the Day (APOD)
NGC 2440: Cocoon of a New White Dwarf
23.01.2005
Like a butterfly, a white dwarf star begins its life by casting off a cocoon that enclosed its former self. In this analogy, however, the Sun would be a caterpillar and the ejected shell of gas would become the prettiest of all!
The Mysterious Voynich Manuscript
22.01.2005
The ancient text has no known title, no known author, and is written in no known language: what does it say and why does it have many astronomy illustrations? The mysterious book was once bought by an emperor, forgotten on a library shelf, sold for thousands of dollars, and later donated to Yale.
Metal on the Plains of Mars
21.01.2005
What has the Opportunity rover found on Mars? While traversing a vast empty plain in Meridiani Planum, one of Earth's yearling rolling robots found a surprise when visiting the location of it own metallic heat shield discarded last year during descent.
A Waterspout off the Florida Keys
20.01.2005
What's happening over the water? Pictured above is one of the better images yet recorded of a waterspout, a type of tornado that occurs over water. Waterspouts are spinning columns of rising moist air that typically form over warm water.
Eight Kilometers Above Titan
19.01.2005
What are these surface features on Titan? Scroll right to see the panoramic view captured last week by the Huygens probe as it descended toward Saturn's mysterious moon. Scientists are not yet sure what the above image is showing.
NGC 346 in the Small Magellanic Cloud
18.01.2005
A satellite galaxy of the Milky Way, the Small Magellanic Cloud (SMC) is a wonder of the southern sky, a mere 210,000 light-years distant in the constellation Tucana. Found among the SMC's clusters and nebulae NGC 346 is a star forming region about 200 light-years across, pictured above by the Hubble Space Telescope.
Titan Landscape
17.01.2005
This color view from Titan gazes across a suddenly familiar but distant landscape on Saturn's largest moon. The scene was recorded by ESA's Huygens probe after a 2 1/2 hour descent through a thick atmosphere of nitrogen laced with methane.
Nebula Nova Cygni Turns On
16.01.2005
Old photographs show no evidence of the above nebula. In 1992, a white dwarf star toward the constellation of Cygnus blew off its outer layers in a classical nova explosion: an event called Nova Cygni 1992.
Huygens Images Titan s Surface
15.01.2005
After a seven year interplanetary voyage on board the the Cassini spacecraft, the European Space Agency's Huygens probe parachuted to a historic landing on Saturn's moon Titan on January 14. Above...
Descent to Titan
14.01.2005
Today's descent to the surface of Titan by the European Space Agency's Huygens probe is the most distant landing ever attempted by a spacecraft from Earth. At 10:13 UT (5:13am...
