2. Los Cielos de Am , The darkest sky and the two galactic hemispheres
I was wondering what conditions should be met to have the "darkest" sky .. ... Upon the above publication of the Southern Galactic hemisphere, TunГ Tezel started seeking opportunities to create the Northern counterpart image. ... So, the initial quest of having the darkest possible sky have delivered us these two all-sky images of the two galactic hemispheres as seen from Planet Earth. Zoomable and 'full-screenable' fisheye view of the "darkest sky" Southern Galactic Hemisphere image. ...

4. ASP: Black Holes to Blackboards: Seeing the Light
... Another option is to buy slides of astronomical objects at different wavelengths to show students why astronomers use different bands of the spectrum to bring out specific characteristics in celestial objects. ... He then uses the camera to scan the entire classroom, asking students to identify what they are seeing. ...

5. (S-7a) The Black Hole at the Center of our Galaxy
... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... HUBBLE UNCOVERS DUST DISK AROUND A MASSIVE BLACK HOLE . Resembling a gigantic hubcap in space, a 3,700 light-year-diameter dust disk encircles a 300 million solar-mass black hole in the center of the elliptical galaxy NGC 7052. ... Because the jets in NGC 7052 are not perpendicular to the disk, it may indicate that the black hole and the dust disk in NGC 7052 do not have a common origin. ... NGC 7052 is located in the constellation of Vulpecula, 191 million light-years from Earth. ...

16. Diffuse Galactic Light in the Large Magellanic Cloud
... Deep optical CCD image of the LMC. Diffuse Galactic Light is plainly visible in this optical image of the Large Magellanic Cloud as a haze over the entire galaxy. The phenomenon arises from starlight scattering off numerous dust clouds in and above the plane of the LMC's disk to form a faint, galaxy-wide reflection nebula. ... The CCD image above was presumably taken with a special wide-field camera at optical wavelengths. ...
