How Type II and III civilizations might communicate with us and which government agency is in charge of first contact?

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - The Earth and Moon may have been formed much later than previously believed. Understanding the history and formation of the Earth is important in determining the potential for habitable worlds around distant stars. See article.
g Message - Interstellar transmissions via energy-markers (photons) or matter-markers (probes) appear to be energetically indistinguishable alternatives for advanced technical societies. Since only Type II and Type III civilizations realistically can afford beacons or star probe technology, alternative distinguishability criteria suggest the possible superiority of intelligent artifacts for contact and communication missions among extraterrestrial cultures. A balanced, more cost-effective Search for Extraterrestrial Intelligence strategy is needed. See article.
g Aftermath - When an alien lands on the White House lawn, who should greet him (her? it?): Someone from the Immigration and Naturalization Service, or someone from the Fish and Wildlife Commission? What rights would an extraterrestrial have? See article.
