Now on ScienceBlogs: Oxytocin: Starting with the basics
Rob Knop's Blog -- ramblings and rants about astronomy, cosmology, science education, general nerdism, and anything else.
Rob Knop earned a PhD in Physics from Caltech in 1997, and did a 5-year post-doc with the Supernova Cosmology Project, and contributed to the discovery of the accelerating Universe. He was an assistant professor of Physics & Astronomy at Vanderbilt for 6 years before scattering out of academia. He now works for Linden Lab, the producers of Second LIfe.

An article from New Scientist suggests that we are shortening the life of the Universe by looking at it. To which I say "foo"— primarily to the New Scientist article, not quite so much to the scientific paper behind it. (I do not leave it completely off the hook, however.)

Astronomers have long assumed that supernovae are the source of at least most of the cosmic rays that hit Earth. Woah, slow down... cosmic rays? Right, you hear the term all the time, but do you really know what they...

Every so often you will come across somebody who has a "killer" list of "problems" with the Big Bang. While there remain unknowns and questions about the Big Bang— just as there do with biological evolution— the basic picture of...

This is mostly just an MLP ("Mindless Link Post"), and it's nearly two weeks late, but there's a post by Julianne over at Cosmic Variance that I think is of crucial importance. People who are outside the field of science...

Following the talk I gave in Second Life about the discovery of the accelerating Universe, we held a couple of Q&A sessions. The original plan was to have questions right after the talk, but the Second Life main grid crashed...

I managed to get through my 15-20 minute "talk," and just as I threw it open for questions Second Life had a database problem and everbody in-world had to be logged out.... We got back in 40 minutes or so...

This is really cool. Several years ago, the Gruber Foundation established a prize in cosmology. Last year (2006) the award went to John Mather and the COBE team; you may recall that Mather was one of the two winners of...

NGC 5135 is a barred spiral, similar in some ways to NGC 1365. Both galaxies are members of the IRAS "Bright Galaxy Sample," meaning that they are very luminous in the infrared as a result of vigorous star-forming activity. Both have very...
