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 - Two massive stars racing in orbit around each other have had their colliding stellar winds X-rayed for the first time, thanks to the combined efforts of ESA's XMM-Newton and NASA's Swift space telescopes. See article.
g Abodes - A new study has found that Vesta once had a molten, swirling mass of fluid inside the asteroid that generated a magnetic field. See article.
g Life - New research is revealing surprising connections between animal microbiomes - the communities of microbes that live inside animals' bodies - and animal behavior, according to a paper by University of Georgia ecologist Vanessa O. Ezenwa and her colleagues. The article, just published in the Perspectives section of the journal Science, reviews recent developments in this emerging research area and offers questions for future investigation. See article.
