Astronomy Picture Of the Day (APOD)
A Higher Dimensional Universe
18.03.2007
Does our universe have higher but unusual spatial dimensions? This idea has been gaining popularity to help explain why vastly separated parts of our universe appear so similar, and why the geometry of our universe does not seem to result naturally from the amounts of matter it seems to contain.
Eiffel Moon
17.03.2007
Celestial and terrestrial lights are featured in this stunning image that includes the Moon in phases of the total lunar eclipse of March 3rd. In the foreground, the distinctively-shaped Eiffel Tower, over 300 meters tall, is a well-known tourist destination and one of the most visited buildings in the world.
Eclipsing the Rings
16.03.2007
The March 3rd total lunar eclipse was widely viewed by denizens of planet Earth. But only a day before, well placed observers could also watch a lunar occultation of Saturn as the planet passed behind the nearly Full Moon.
NGC 2442: Galaxy in Volans
15.03.2007
Distorted galaxy NGC 2442 can be found in the southern constellation of the flying fish, (Piscis) Volans. Located about 50 million light-years away, the galaxy's two spiral arms extending from a pronounced central bar give it an ominous hook-shaped appearance.
Barred Spiral Galaxy M95
14.03.2007
Why do some spiral galaxies have a ring around the center? First and foremost, M95 is one of the closer examples of a big and beautiful barred spiral galaxy. Visible in the above recent...
Attacking Mars
13.03.2007
The Spirit rover attacked Mars again in 2005 September. What might look, above, like a military attack, though, was once again just a scientific one - Spirit was instructed to closely inspect some interesting rocks near the summit of Husband Hill.
Watch Jupiter Rotate
12.03.2007
What would it be like to coast by Jupiter and watch it rotate? This was just the experience of the New Horizons spacecraft as it approached and flew by Jupiter earlier this year. Clicking on the image will bring up a movie of what the robotic spacecraft saw.
The Einstein Cross Gravitational Lens
11.03.2007
Most galaxies have a single nucleus -- does this galaxy have four? The strange answer leads astronomers to conclude that the nucleus of the surrounding galaxy is not even visible in this image. The central cloverleaf is rather light emitted from a background quasar.
Eclipse with Lighthouse
10.03.2007
A red Moon rose over Cape Cod, Massachusetts, USA on March 3rd, immersed in Earth's shadow near the total phase of a lunar eclipse. This serene portrait of the eclipsed Moon in a dark blue twilight sky also features the Highland Lighthouse (aka Cape Cod lighthouse), another more locally familiar beacon in the night.
Eclipse and Ecliptic
9.03.2007
When a Full Moon lies near the ecliptic there can be a lunar eclipse. That cosmic alignment is well illustrated in this composite of eclipse images recorded last Saturday near Paris, France. The projection...
