Astronomy Picture Of the Day (APOD)
Io's Active Volcanoes27.10.1996
Why is Io green at night? In this just-released nighttime picture of Jupiter's moon Io, the red spots clearly show Io's current volcanically active regions. But what is causing the global green sheen? This telling picture was taken by the automated Galileo spacecraft currently orbiting Jupiter while Io was in Jupiter's shadow.
Mir Over New Zealand
26.10.1996
The Russian space station Mir was photographed last month high above New Zealand. Before returning with record-breaking astronaut Shannon Lucid, the space shuttle Atlantis crew took this breathtaking view from the Space Shuttle Atlantis. Atlantis had just undocked from Mir and was preparing to return to Earth.
A Flyby View of Ganymede
25.10.1996
This is what it would look like to fly over the surface of Jupiter's moon Ganymede. NASA's robot spacecraft Galileo recently approached only 6000 miles from this frozen ice-ball of a moon. The above image is a digital reconstruction from two images taken during this flyby.
Starbirth in the Lagoon Nebula
24.10.1996
Stars are forming even today in the Lagoon Nebula. This bright nebula is visible in the constellation of Sagittarius with binoculars. The above photo is the result of a new sensitive camera being attached to one of the world's largest telescopes.
The Large Cloud of Magellan (LMC)
23.10.1996
Magellan and his crew had plenty of time to study the southern sky during their famous voyage around the world. As a result, two fuzzy cloud like objects in the southern sky are now known as the Clouds of Magellan. These star clouds are small irregular galaxies, satellites of our larger Milky Way spiral galaxy.
The Cracked Ice Plains of Europa
22.10.1996
What caused the cracks in this giant ice-ball? Jupiter's moon Europa has smoothest surface in the solar system and is composed mostly of cracked water-ice. In the above false-colored picture released last week...
Orionids Meteor Shower to Peak Tonight
21.10.1996
Tonight you might be able to see Halley's Comet again - or at least some pieces of it. It is widely thought that that the meteors from the Orionids meteor shower, which peaks tonight, are just small pieces of Halley's Comet falling to Earth.
Surveyor Slides
20.10.1996
"Safe!" -- In September 1967 (during regular season play), while making a successful soft landing on the Moon's Mare Tranquillitatis, the Surveyor 5 lander actually slid several feet. Equipped with television cameras and some...
Lalande 21185: The Nearest Planetary System?
19.10.1996
What's the closest extrasolar planetary system? It may well be planets of the dim red dwarf star cataloged as Lalande 21185 -- a mere 8 light years distant. This star is too faint to be seen by the naked eye and its planets have not been imaged directly.
Jupiter's Auroras
18.10.1996
Auroras are especially large on Jupiter. In pictures released yesterday, the Hubble Space Telescope imaged these unusual light displays in more detail than ever before. Jupiter's auroras are linked to its volcanic moon Io.
