Information:  - Big Picture Science (formerly titled Are We Alone?) is the SETI Institute's weekly science radio program, hosted by Senior Astronomer Seth Shostak and Molly Bentley, the executive producer of the radio show.  - Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf.  - The Neckar is a river in Germany, mainly flowing through the southwestern state of Baden-Württemberg, with a short section through Hesse. The Neckar is a major right tributary of the Rhine. Rising in the Black Forest near Villingen-Schwenningen in the "Schwenninger Moos" conservation area at a height of above sea level, it passes through Rottweil, Rottenburg am Neckar, Kilchberg, Tübingen, Wernau, Nürtingen, Plochingen, Esslingen, Stuttgart, Ludwigsburg, Marbach, Heilbronn and Heidelberg, before discharging into the Rhine at Mannheim, at above sea level.   - The SETI Institute is a not-for-profit research organization whose mission is to explore, understand, and explain the origin and nature of life in the universe, and to apply the knowledge gained to inspire and guide present and future generations. It aims for discovery and for sharing knowledge as scientific ambassadors to the public, the press, and the government. SETI stands for the "search for extraterrestrial intelligence". The Institute consists of three primary centers: The Carl Sagan Center, devoted to the study of life in the universe, the Center for Education, focused on astronomy, astrobiology and space science for students and educators, and the Center for Public Outreach, producing "Big Picture Science," the Institute's general science radio show and podcast, and "SETI Talks" weekly colloquium series.   - Laurance R. Doyle ( born 1953 ) is an American scientist who received his Ph.D. from the Ruprecht Karl University of Heidelberg . He has worked at the SETI Institute since 1987 where he is a principal investigator and astrophysicist . His main area of study has been the formation and detection of extrasolar planets , but he has also worked on communications theory . In particular he has written on how patterns in animal communication relate to humans with an emphasis on cetaceans . He grew up on a dairy farm in Cambria , California and therefore did n't have much access to information about stars . But by reading books at the local library , Doyle was able to develop his knowledge in astronomy , and eventually obtain his Bachelor 's and Master 's of Science degrees in astronomy from San Diego State University . His first job was at the Jet Propulsion Laboratory as an imaging engineer , where he was in charge of analysing pictures of Jupiter and Saturn sent from the spacecraft Voyager . He moved to Heidelberg , Germany , to help analyse images of Halley 's Comet . He got his doctorate in Astrophysics at the University of Heidelberg . In May 2005 he appeared on a National Geographic Channel special titled Extraterrestrial . He also appeared in the episode `` Will We Survive First Contact '' , of The Science Channel series titled Morgan Freeman 's Through the Wormhole . Doyle is currently seeking to compare dolphin whistles and baby babble in an attempt to make predictions about extraterrestrial communications . He believes that by measuring the complexity of communications for different species on earth , we could get a good indication of how advanced an extraterrestrial signal is . His study determined that babies babble over 800 different sounds with the same amount of frequency as dolphins . As they grow older , those sounds decrease to around 50 and become more repetitious . The study found that baby dolphins develop similarly with regards to their whistling .  - Heidelberg is a university city situated on the river Neckar in south-west Germany. At the 2015 census, its population was 156,257, with roughly a quarter of its population being students.   - Carl Edward Sagan (November 9, 1934  December 20, 1996) was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences. He is best known for his work as a science popularizer and communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space: the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the now accepted hypothesis that the high surface temperatures of Venus can be attributed to and calculated using the greenhouse effect.

Q: Information:  - Americans are citizens of the United States of America. The country is home to people of many different national origins. As a result, Americans do not equate their nationality with ethnicity, but with citizenship and allegiance. Although citizens make up the majority of Americans, non-citizen residents, dual citizens, and expatriates may also claim an American identity.  - Ethiopian Americans are Americans of Ethiopian descent as well as individuals of American and Ethiopian ancestry. History. In 1919, an official Ethiopian goodwill mission was sent to the United States to congratulate the Allied powers on their victory during the First World War. The four-person delegation included "Dejazmach" Nadew, the nephew of Empress Zawditu and Commander of the Imperial Army, along with "Blattengeta" Heruy Welde Sellase, Mayor of Addis Ababa, "Kentiba" Gebru, Mayor of Gondar, and Ato Sinkas, "Dejazmach" Nadew's secretary.  - Gondar or Gonder ("Gonder" or "Gondär"; formerly , "Gandar" or "Gender") is a city and separate woreda in Ethiopia. Located in the Semien Gondar Zone of the Amhara Region, Gondar is north of Tana Lake on the Lesser Angereb River and southwest of the Simien Mountains. It has a latitude and longitude of with an elevation of 2133 meters above sea level. It is surrounded by the Gondar Zuria woreda.  - This is a list of Ethiopian Americans .
