What to say to ETI and supernova in 3-D

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Researchers have now carried out the first fully three-dimensional computer simulations of a core collapse supernova over a timescale of hours after the initiation of the blast. They thus could answer the question of how initial asymmetries, which emerge deep in the dense core during the very early stages of the explosion, fold themselves into inhomogeneities observable during the supernova blast. See article.
g Life - How can a tiny spider body contain material for several decimeters of gossamer silk, and what governs the conversion to thread? See article.
g Message - "If you're sending a message to extraterrestrials, what you want to send is what's special about us and our planet — what is unusual," according to SETI astronomer Frank Drake. See his essay. Note: This essay is from 2006.
g Learning - The recent brouhaha over whether there’s compelling evidence for life on Mars offers a stark lesson about research life: a major scientific discovery is a temptress as beguiling, and as dangerous, as the Sirens that beckoned Ulysses. See article. Note: This article is from 2005.
