This is comet 17P/Holmes on the evening 11/14/07.
Astronomers estimate that this expanding ball of dust and gas is now the
largest object in the solar system! The faint tail seen in the image
below has detached from body of the comet a few days ago and has faded from
view. The bright area towards the upper right is glow from the
star Mirfak (Alpha Perseus).

The image above
shows comet 17P/Holmes on the evening 11/02/07. In addition to the
head, a faint tail can be seen exiting toward the top and right. The comet
continues to grow in size though not quite as much as the comparison images below
would suggest. This image was taken with a different camera setup that
has roughly 1/2 of the field of view as the images below. To suggest an idea of the size of the comet on this
night, four full moons could easily be placed in this image.

The image above
shows comet 17P/Holmes on the evening 10/24/07. At best it can be
described as a bright dot that is somewhat larger than the
surrounding stars.

<mouseover shows constellation lines and comet location>
The image above
shows the location of comet 17P/Holmes on the evening 10/24/07. During the previous 24 hours the comet had undergone a
brightness change that moved it from the realm of large telescopes to naked
eye visibility. Though the comet is bright, no tail is visible.
This makes it hard to distinguish from the stars in the image above.
However if you mouseover the image, constellation lines marking Perseus will
appear and 17P/Holmes will be circled. |
