Astronomy Picture Of the Day (APOD)The Small Cloud of Magellan
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.
The Large Cloud of Magellan
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, nestled among the southern constellations of Doradus and Tucana are now known as the Clouds of Magellan.
Thousands of Coma Cluster Galaxies
Almost every object in the above photograph is a galaxy. The Coma Cluster of galaxies pictured is a dense cluster containing many thousands of galaxies. Many of these galaxies contain as many stars as our own Milky Way Galaxy.
Rockets and Robert Goddard
Robert H. Goddard, one of the founding fathers of modern rocketry, was born in Worcester Massachusetts in 1882. As a 16 year old, Goddard read H.G. Wells' science fiction classic "War Of The Worlds" and dreamed of spaceflight. By 1926 he had designed, built, and launched the world's first liquid fuel rocket.
Space Station Mir Over Earth
This picture of the Russian space station Mir over the Pacific Ocean was recorded by the Space Shuttle Discovery in February 1995. During this mission Discovery performed a rendezvous and "fly around" with Mir in preparation for a future docking mission.
The Far Side
This historic picture was humanity's first glimpse of the far side of the Moon. It was taken by the Soviet spacecraft Luna 3 in October of 1959. Luna 3 followed closely...
Elliptical Galaxy M87
Elliptical galaxy M87 is a type of galaxy that looks much different than our own Milky Way Galaxy. But even for an elliptical galaxy M87 is peculiar. M87 is much bigger than an average...
Spiral Galaxy M83
Long winding spiral arms are clearly evident on this spectacular picture of the spiral galaxy M83. The blue color of the spiral arms is caused by the relatively large fraction of young blue stars there. Dark dust lanes are mixed in with the stars and trace the spiral structure of the galaxy.
Proplyds: Infant Solar Systems
The fuzzy blobs seen above may be some of the first ever images of entire solar systems forming right before our eyes. This close up of the Orion Nebulae taken by the Hubble Space...
White Dwarfs Cool
The circled stars in the above picture are from a class that is hard to see in the cosmos: white dwarfs. The entire photo covers a small region near the center of a globular cluster known as M4. Researchers using the Hubble Space Telescope discovered a large concentration of white dwarfs in M4.
