A scientific perspective on the Avatar movies.

Why Earth 2.0 may not be such a feasible place for people to live.

There are many planets in the universe, but very few of them have qualities to support life Taking one celestial body at a time and determining whether it supports life would be slow and inefficient. So, astronomers look for certain...

Learn about the Goldilocks Zone aka the Habitable Zone where a planet like Earth is able to have liquid water and sustain life as we know it with this song by KLT

As we continue our search for earth-like, potentially habitable worlds, we come across an interesting triple-star system called Gliese 667. The smallest of these three stars, Gliese 667 C, is a red dwarf with several planets, one of...

Extrasolar planets, or exoplanets, are planets that orbit stars other than our sun. Astronomers like Dr. William Welsh at San Diego State University primarily use two methods to detect these distant planets: Doppler and Transit...

Originally aired on February 27, 2009, a conversation on the Kepler Mission with Principal Investigator William Borucki, Deputy Principal Investigator David Koch, and Kepler Science Council Member Alan Boss from the Carnegie Institute of...

Vladimir Airapetian, scientist at NASA’s Goddard Space Flight Center, explains what researchers hope to find as they gaze beyond our solar system.

Listen to Chief Scientist Jim Green and a co-investigator on the Kepler and TESS missions, Jon Jenkins, discuss exoplanet-hunting and all the amazing discoveries Kepler has made.

While more research is needed, Smith and others are fascinated by the possibility that airborne microbes could also be found elsewhere in the solar system, and beyond.

Giada Arney, astrophysicist at NASA’s Goddard Space Flight Center, is looking at the potential for K stars to host habitable worlds. Learn about how stars affect planetary environments and why complex life on early Earth was impossible.

A conversation with Rus Belikov and Eduardo Bendek, senior research scientists at NASA’s Ames Research Center, working on next generation technology to directly image planets beyond the solar system.

A conversation with Steve Howell, NASA Senior Research Scientist on astrophysics.

What do we know about the planets outside our solar system? NASA planet hunters Jessie Christiansen and Knicole Colon take us beyond...into the exciting world of exoplanets.

A conversation with Lika Guhathakurta, lead program scientist for new initiatives in the Exploration Technology Directorate at NASA's Ames Research Center in Silicon Valley, and Ryan McGranaghan, postdoctoral researcher from NASA’s Jet...

A conversation with Susan Thompson, Kepler research scientist for the SETI Institute at NASA’s Ames Research Center in Silicon Valley.

NASA's Kepler space telescope has discovered a planet in a habitable zone around a star with similar conditions to our own Sun. Kepler 22b's year is 290 days long and scientsts estimate the surface temperature is around 72 degrees,...

The thing to remember here is that finding life on another planet tells us one of very two things...and we will be able to figure out which thing pretty quickly. Either:



1. The life will contain clear signals that it is...

A conversation with Chris McKay, senior scientist at the Planetary Systems Branch of NASA's Ames Research Center who works on projects from Cassini to Curiosity.

NASA’s ‘TESS’ mission has found a possible Earth-sized habitable planet. <br/>

On a quest to find out if we are not alone in the universe, Ravi Kopparapu at NASA Goddard studies how we could use telescopes to detect signs of life beyond our solar system.
