The NGC Ten Minute Challenge
NGC 3628 - Galaxy in Leo
NGC 3628 forms the "Leo Triplet" with M65 and M66. NGC 3628 is seen
edge-on with a broad band of dust hiding most of the spiral arms. The
dust band is clearly distorted by the gravitational interaction with
its two bright neighbours.

Images of Saturn (1) - Spotting the Shepherd Moon
Across the darkened expanse of Saturn's rings, the Cassini spacecraft
spies one of the F-ring shepherd moons.
Pandora (84 kilometers, or 52 miles across) orbits Saturn just beyond
the outer edges of the F ring. Close to the planet, the image of the
rings is sl ...

Decline of AT CNC - December 2007 onwards
Dwarf Novae are close binary systems with an accretion disc around the
white dwarf component. Outbursts from 2 to 9 magnitudes, lasting for a
day or two, occur at quasi-periodic intervals of days to years. Many
of these stars are ultraviolet and X-ray variable. Most UG's ...

Density of the universe
Wed, 6 Feb 2008 01:13:30 -0000
Were the universe uniformly populated with matter, the density of the
universe* would be constant across all scales; as the mass enclosed in a
sphere of radius r would increase as r^3.
As observed, matter is condensed into stars and stuff and galaxies and
clusters of galaxies. By the time we are getting to cl ...

Security Light
Tue, 05 Feb 2008 08:32:29 +0000
FFS the first proper clear night in ages, and it seems the guy out the
back has decided to install a security light. Which blazed all night. In
fact, it is still on now.
I'll be popping round later for a word. Politely of course, it *could*
