Galaxy evolution and Vegetation Red-Edge

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 - A new finding indicates that not all massive, luminous galaxies formed shortly after the Big Bang. The study could yield new information about the origin and evolution of galaxies. See article.
g Abodes - The so-called Vegetation Red-Edge is a characteristic of vegetation spectra, and can therefore be used as a biomarker if it can be detected in an unresolved extrasolar Earth-like planet integrated reflectance spectrum, researchers say. See article.
g Intelligence - Quote of the Day: "Empty space is like a kingdom, and earth and sky are no more than a single individual person in that kingdom./Upon one tree are many fruits, and in one kingdom there are many people./How unreasonable it would be to suppose that, besides the earth and the sky which we can see, there are no other skies and no other earths." - Teng Mu, a Chinese scholar of the Sung Dynasty (960-1280 A.D.)
g Cosmicus - From a planetary security perspective, we can theoretically safeguard our species by expanding out in our own system with space-based habitats and possibly terraforming as options. The question then remains: What is it that drives the push to interstellar flight? See article.

Hi Desh,

I'm delighted that you'd like to link to my blog, and I will be certain to take a look at yours. It's an exciting time to be alive in the field of astrobiology and astronomy - pardon my Eurocentrism, but it's akin to the Portuguese making their first trips down the African coast in search of the Orient ... any day now, we're going to sail across the Atlantic and discover any entirely new world.
The name is Rob; go to for more about me.
