On July 17th, NASA's Wide-field Infrared Survey Explorer
(WISE) satellite completed its first survey of the entire sky viewable from Earth
. After just seven months in orbit, WISE -- a precursor to the planned James Webb Space Telescope
-- has returned more than a million images that provide a close look at celestial objects
ranging from distant galaxies
. The first release of WISE data, covering about 80 percent of the sky, will be delivered to the astronomical community in May of next year
, but in the meantime we can see some of the images and animations that NASA has released to date: Galleries (containing just a small selection of images)
. Videos and Animations: 1

The Sky At Night
Every episode of the BBC science series made since the end of 2001 viewable online. Anything I know about the universe I learnt from Patrick Moore.

IN 1877 Isabel Gill visited an inhospitable volcanic blob
in the mid-Atlantic to help her husband
with ground-breaking astronomical measurements.
Then she wrote a wrote a book
about it, including an attempt to explain to fellow Victorian ladies the concept of a solar parallax in terms she thought they might be able to grasp:"I myself do not understand mathematical terms, so how could I use them with the hope of explaining these things to my readers? However, I can use knitting-needles, and perhaps they may do just as well."
Wierdly, more than a century later
visited the site and found the sandy paths which marked the Gill's lava-top camp still undisturbed by the Atlantic winds.

Quark Star Observations of two stars, one unusually small and the other unusually cold, have led astronomers to think they are seeing evidence of a new form of matter and a new kind of star, one possibly made of elementary particles known as quarks and denser than any cosmic object other than a black hole.
(NYT link: yada yada) Here's a related link
on neutron stars and quark matter. I rather like the phrase strange quark matter
... Anybody else hear about this?
