Killing private space

The financial foolishness in Congress, by Republicans this time, continues. In making its budget recommendations for NASA, the report [pdf] of the House Appropriations Commerce, Justice, Science, and Related Agencies subcommittee also demands that NASA immediately choose one commercial company for its commercial space program. (Hat tip to Clark Lindsey for spotting this.)

The number of ways this action is counter-productive almost can’t be counted.

Four TSA screeners have been charged with accepting cash in exchange for allowing drug smugglers pass through security.

This should make you you feel safer: Four TSA screeners have been charged with accepting cash in exchange for allowing drug smugglers to pass through security.

And in related news: A family missed its flight after TSA agents insisted on giving a seven-year-old girl with cerebral palsy a full pat-down.

Vast Polar Structure

A new study by astronomers has found a vast structure of satellite galaxies and star clusters aligned perpendicular to the Milky Way and extending outward above and below the galaxy’s nucleus by as much as a million light years.

In their effort to understand exactly what surrounds our Galaxy, the scientists used a range of sources from twentieth century photographic plates to images from the robotic telescope of the Sloan Deep Sky Survey. Using all these data they assembled a picture that includes bright โ€˜classicalโ€™ satellite galaxies, more recently detected fainter satellites and the younger globular clusters.

โ€œOnce we had completed our analysis, a new picture of our cosmic neighbourhood emergedโ€, says Pawlowski. The astronomers found that all the different objects are distributed in a plane at right angles to the galactic disk. The newly-discovered structure is huge, extending from as close as 33,000 light years to as far away as one million light years from the centre of the Galaxy.

An animation illustrating this galactic distribution is posted below the fold. You can read the actual preprint paper here.

The problem with this polar alignment with the Milky Way’s core is that the theories for explaining the distribution of dark matter do not predict it.
