Warped Sky: Star Trails Panorama
Explanation:
What's happened to the sky?
A time warp, of sorts, and a digital space warp too.
The time
warp occurs because the
above image
captured in a single frame a four hour exposure of the night sky.
Prominent and picturesque
star trails
are visible.
The space warp occurs because the above image is actually a full
360 degree panorama
, horizontally
compressed
to fit your browser.
As the
Earth rotated
,
stars appeared to circle both the South
Celestial Pole
, on the left, and the
North Celestial Pole
,
which occurs just below the horizon on the right.
The
above image
captured the sky over
Mudgee
,
New South Wales
,
Australia
,
including the domes of two large telescopes artificially lit by red light.
A horizontally unwarped image is visible by clicking on the above image.
