Professor at University of Puerto Rico at Arecibo makes impact on the Study of Planetary Habitability
Professor Abel Mendez has been a dynamic force in scientific research within the University of Puerto Rico system for over 15 years. Mendez, a biophysicist, currently serves as an Associate Professor of Physics and Chemistry at the University of Puerto Rico at Arecibo. Professor Mendez’s research focus is the study of planetary habitability and the development of habitability models to understand the interactions between life and terrestrial or planetary environments.The students in Professor Mendez laboratory enjoy being surrounded by a role model that has such a passion for his work and can help them fulfill...November 23, 2009 / Written by: Benita P.

NOVA ScienceNOW - Hunt for Alien Earths
NOVA’s ScienceNOW series, hosted by Neil de Grasse Tyson, has just released a new episode called Hunt for Alien Earths which is devoted to the work of astronomers who search for planets orbiting other stars that might host life. Astrobiologists Lisa Kaltenegger, David Charbonneau, and Geoff Marcy are featured in this beautifully produced, twelve minute video.

Reflections of Chirality as a Possible Biomarker
Scientists have come up with a novel way to detect life on other planets. Rather than try to measure the composition of atmospheres, they want to look at the chirality of light coming from the planet. “If the [planet’s] surface had just a collection of random chiral molecules, half would go left, half right,” says author T.A. Germer of the National Institute of Standards and Technology. “But life’s self-assembly means they all would go one way. It’s hard to imagine a planet’s surface exhibiting handedness without the presence of self assembly, which is an essential component of...

To See a Clear Day From Far Away
With the launch of NASA’s new Kepler spacecraft, the chances of discovering Earth-sized planets in Earth-like orbits around distant stars have increased. However, the real question for astrobiologists is, are these worlds habitable? Can we find an Earth-like planet with an Earth-like atmosphere? Answering such questions may prove to be very difficult.
Future missions like the James Webb Space Telescope (now scheduled for launch in 2013) may help astronomers characterize the atmospheres of distant planets, helping astrobiologists identify a true Earth twin beyond our solar system.Source: [Astrobiology Magazine]

Finding Earth’s Twin: No Easy Task
NASA’s new Kepler mission is scheduled to launch in just a couple of days. Once in orbit, the powerful telescope will provide astrobiologists with the ability to search for rocky, Earth-like planets around distant stars. Ultimately, Kepler will help us determine if these potentially life-supporting worlds are common or rare in the Universe.
