Astronomy Picture Of the Day (APOD)
A Venusian Landscape
27.09.1995
This computer generated view of a Venusian volcano was created using data from NASA's Magellan spacecraft. Magellan used its onboard radar to map the surface of Venus which is hidden from telescopic observations by a perpetual cloud cover.
A Venus Landing
26.09.1995
This image is part of the first color panoramic view from Venus. It was transmitted by a TV camera on the Soviet Venera 13 lander which parachuted to the surface on March 1, 1982.
Star Trails in Southern Skies
25.09.1995
As the Earth spins on its axis, the sky seems to rotate around us. This motion produces the beautiful concentric arcs traced out by the stars in this time exposure of the night sky. In the foreground of the picture is the dome of the Anglo-Australian Telescope in central New South Wales Australia.
Orion's Horsehead Nebula
24.09.1995
The black indentation to the red emission nebula seen just to the right of center of the above photograph is one of the most famous features in any nebulae on the sky. Because of its shape, it is known as the Horsehead Nebula.
Mimas: Small Moon with A Big Crater
24.09.1995
Mimas is one of the smaller moons of Saturn but shows one of the largest impact craters! In fact, if the impact had been much greater, it would have disrupted the entire satellite. The large crater has been named Herschel after the 1789 discoverer of Mimas, Sir William Herschel.
Titan: Saturn's Smog Moon
23.09.1995
The largest moon of Saturn is a rare wonder. Titan is the only one of Saturn's moons with an atmosphere, and one of only two moons in the Solar System with this distinction (Neptune's Triton is the other).
Standing on the Moon
22.09.1995
Pictured, the second person to walk on the Moon: Edwin "Buzz" Aldrin. During this Apollo 11 mission, Neil Armstrong and Buzz Aldrin landed on the Moon while Michael Collins circled in the Command Module above.
One Small Step
21.09.1995
On July 20th, 1969, a human first set foot on the Moon. Pictured above is the first lunar footprint. The footprint and distinction of the first person to walk on the Moon belong to Neil Armstrong.
GL 105C: The Coolest Star?
20.09.1995
Is the dim star to the upper right of this false-color picture the coolest possible normal star? From this recent picture by the Hubble Space Telescope, astronomers have estimated its mass is just high enough for it to fuse hydrogen into helium in its core.
The Small Cloud of Magellan
19.09.1995
Almost unknown to casual observers in the northern hemisphere, the southern sky contains two diffuse wonders known as the Magellanic Clouds. The Magellanic Clouds are small irregular galaxies orbiting our own larger Milky Way spiral galaxy.
