Starlight Reflections
14.04.1998
Wisps of dust fill the space between the stars. This dust is usually invisible, subtly acting to dim the light of more distant stars. Sometimes this dust is thick and prominent as dark patches on otherwise bright emission nebulae. Other times this dust may show itself by reflecting the light of bright, nearby stars.
A Chamaeleon Sky
23.03.1999
A photogenic group of nebulae can be found in Chamaeleon, a constellation visible predominantly in skies south of the Earth's equator. Towards Chamaeleon, dark molecular clouds and bright planetary nebula NGC 3195 can be found. Visible near the center of the above photograph is a reflection nebula surrounding a young bright star.
A Chamaeleon Sky
9.06.2002
A photogenic group of nebulae can be found toward Chamaeleon, a constellation visible predominantly in skies south of the Earth's equator. Celestial objects visible there include the blue reflection nebulas highlighted by thin dust surrounding the bright stars in the above image center.
NGC 869 and NGC 884: A Double Open Cluster
2.12.2003
Most star clusters are singularly impressive. Open clusters NGC 869 and NGC 884, however, are doubly impressive. Also known as "h and chi Persei", this unusual double cluster, shown above, is bright enough to be seen from a dark location without even binoculars.
Orion: The Big Picture
1.12.1997
Orion is big. Some of the stars that form the constellation of Orion are part of a giant gas cloud complex that stretches over 100 light years and appears more than 50 times the diameter of the Moon.
M13: The Great Globular Cluster in Hercules
19.08.1998
M13 is one of the most prominent and best known globular clusters. Visible with binoculars in the constellation of Hercules, M13 is frequently one of the first steps beyond the ordinary visible to the casual sky gazer.
Nearby Spiral M33
14.12.2004
Spiral galaxy M33 is a mid-sized member of our Local Group of Galaxies. M33 is also called the Triangulum Galaxy for the constellation in which it resides. About four times smaller (in radius) than...
NGC 869 and NGC 884: A Double Open Cluster
11.10.2005
Most star clusters are singularly impressive. Open clusters NGC 869 and NGC 884, however, are doubly impressive. Also known as "h and chi Persei", this unusual double cluster, shown above, is bright enough to be seen from a dark location without even binoculars.
Green Fireball
20.11.1998
"Goodness, Gracious, Green Balls Of Fire!", might have been an appropriate theme song title for the 1998 Leonid meteor shower. Many observers, like astrophotographer Steve Dunn watching from Cape Canaveral, Florida, USA, reported that a lot of the characteristically bright Leonid meteors had a greenish tint.
Kembles Cascade
14.08.2000
A picturesque chain of unrelated stars is visible with strong binoculars towards the constellation of Camelopardalis. Known as Kemble's Cascade, the asterism contains about 20 stars nearly in a row stretching over five times the width of a full moon.
