The space war heats up

It appears the space war is heating up again. This analysis of the NASA authorization legislation issued by the House yesterday notes that it has serious differences with the Senate bill. The article notes that the House bill does not fund an additional shuttle mission while insisting that the government continue the construction of some variation of the Orion capsule and Ares rockets.

A quick note on the past weekend caving

I just thought I should note quickly that my weekend cave trip was a spectacular success. John Harman, Pete Johnson, Nikki Fox, and myself surveyed almost 800 feet of beautiful and big virgin cave passage. I hope to have pictures soon.

Man, it is really fun to go where no one has ever gone before!

Metals in the inner galaxy

A preprint paper, published today on the astro-ph website but also accepted for publication in the journal Astronomy & Astrophysics, has confirmed what scientists have suspected about the dust and gas between the stars: As you travel closer to the center of the Milky Way galaxy this interstellar medium gets increasingly enriched with heavy elements. The scientists believe this is because the higher rate of supernovae in the inner galaxy sprays space with more of these atoms.

Since the field of extrasolar planets has also found that the more heavy elements a star contains, the more chance it will have planets, the new results above suggest that we will find more planets as we look inward towards the galactic center.
