Sharpless 171
18.10.2008
Cosmic pillars of cold molecular gas and clouds of dark dust lie within Sharpless 171, a star-forming region some 3,000 light-years away in the royal constellation Cepheus. This tantalizing false-color skyscape spans about 20 light-years across the nebula's bright central region.
An Extraordinary Voyage
17.10.2008
Nineteenth century science fiction author Jules Verne wrote visionary works about Extraordinary Voyages including tales of space flight and the story of a journey From the Earth to the Moon. Fittingly, the European Space...
48 Years of Space Flight
16.10.2008
This year, NASA celebrated its 50th anniversary. Inspired to make his own contribution, astronomer Ralf Vandebergh set out to record images of some historic spacecraft in Earth orbit -- captured with his own modest equipment and a hand-guided, 10-inch, Newtonian reflecting telescope. One result is this intriguing composite effectively spanning 48 years of space flight!
Camera Orion
15.10.2008
Orion, the Hunter, is one of the most easily recognizable constellations in planet Earth's night sky. But Orion's stars and nebulas don't look quite as colorful to the eye as they...
An Enceladus Tiger Stripe from Cassini
14.10.2008
What creates the unusual tiger stripes on Saturn's moon Enceladus? No one is sure. To help find out, scientists programmed the robotic Cassini spacecraft to dive right past the plume-spewing moon last week.
Cassini Passes Through Ice Plumes of Enceladus
13.10.2008
What telling impurities taint the ice plumes of Enceladus? To help answer this question, the robotic Cassini spacecraft dove last week to within 30 kilometers of Saturn's ice-plume emitting moon. At this closest-ever...
Spiral Galaxy NGC 3370 from Hubble
12.10.2008
Is this what our own Milky Way Galaxy looks like from far away? Similar in size and grand design to our home Galaxy (although without the central bar), spiral galaxy NGC 3370 lies about 100 million light-years away toward the constellation of the Lion (Leo).
Bright Bolide
11.10.2008
On September 30, a spectacular bolide or fireball meteor surprised a group of amateur astronomers enjoying dark night skies over the Oklahoma panhandle's Black Mesa State Park in the Midwestern US. Flashing past...
Irregular Galaxy NGC 55
10.10.2008
Irregular galaxy NGC 55 is thought to be similar to the Large Magellanic Cloud (LMC). But while the LMC is about 180,000 light-years away and is a well known satellite of our own Milky Way Galaxy, NGC 55 is more like 6 million light-years distant and is a member of the Sculptor Galaxy Group.
Massive Stars in NGC 6357
9.10.2008
Massive Stars lie within NGC 6357, an expansive emission nebula complex some 8,000 light-years away in the tail of the constellation Scorpius. In fact, positioned just below center in this close-up view...
