NGC 3621: Far Beyond the Local Group
19.09.2009
Far beyond the local group of galaxies lies NGC 3621, some 22 million light-years away. Found in the multi-headed southern constellation Hydra, the winding spiral arms of this gorgeous island universe are loaded with luminous young star clusters and dark dust lanes.
Take My Hand
18.09.2009
Get out your red/blue glasses and check out this close-up of spacesuited NASA astronaut John Olivas outside the International Space Station. Carefully constructed from two photographs (ISS020-E-038481, ISS02-0E-038482) taken during space shuttle orbiter Discovery...
Ultraviolet Andromeda
17.09.2009
Taken by a telescope onboard NASA's Swift satellite, this stunning vista represents the highest resolution image ever made of the Andromeda Galaxy (aka M31) - at ultraviolet wavelengths. The mosaic is composed of 330 individual images covering a region 200,000 light-years wide.
The Tarantula Zone
16.09.2009
The Tarantula Nebula is more than 1,000 light-years in diameter -- a giant star forming region within our neighboring galaxy the Large Magellanic Cloud (LMC). That cosmic arachnid lies left of center in this in this colorful telescopic image taken through narrow-band filters. It covers a part of the LMC over 2,000 light-years across.
NGC 6888: The Crescent Nebula
15.09.2009
NGC 6888, also known as the Crescent Nebula, is a cosmic bubble about 25 light-years across, blown by winds from its central, bright, massive star. This beautiful portrait of the nebula is from the Isaac Newton Telescope at Roque de los Muchachos Observatory in the Canary Islands.
The Center of Globular Cluster Omega Centauri
14.09.2009
What is left over after stars collide? To help answer this question, astronomers have been studying the center of the most massive ball of stars in our Milky Way Galaxy. In the center of globular cluster Omega Centauri, stars are packed in 10,000 times more densely than near our Sun.
The Holographic Principle
13.09.2009
Is this picture worth a thousand words? According to the Holographic Principle, the most information you can get from this image is about 3 x 10 65 bits for a normal sized computer monitor.
Summer Night in Astronomy Town
12.09.2009
This serene view records a late summer night sky over the rolling, green hills of planet Earth. It was taken near the rural village of Saadat Shahr, Fars province, in southern Iran. Saadat Shahr is also known as Astronomy Town, as the inhabitants have demonstrated a remarakble passion for sky gazing.
Stephan s Quintet
11.09.2009
The first identified compact galaxy group, Stephan's Quintet is featured in this stunning image from the newly upgraded Hubble Space Telescope. About 300 million light-years away, only four galaxies of the group are actually locked in a cosmic dance of repeated close encounters. The odd man out is easy to spot, though.
The Butterfly Nebula from Upgraded Hubble
10.09.2009
The bright clusters and nebulae of planet Earth's night sky are often named for flowers or insects, and NGC 6302 is no exception. With an estimated surface temperature of about 250,000 degrees...
