Latest Terrestrial Planet Finder Stories
Earthshine â€“ sunlight reflected from the Earth toward the Moon â€“ may provide a way for researchers to seek out oceans on other planets, according to researchers.
Astronomers at NASA's JPL have recently concluded that the upcoming planet-finding mission, SIM PlanetQuest, would be able to detect an Earth-like planet around the star 40 Eridani, a planet familiar to "Star Trek" fans as "Vulcan."
For the first time ever, NASA researchers have successfully demonstrated in the laboratory that a space telescope rigged with special masks and mirrors could snap a photo of an Earth-like planet orbiting a nearby star.
Beth A. Biller is part of an international team of astronomers trying to tease out images of planets around young stars by removing the distortions caused by Earth's atmosphere.
More than a decade after the first planets beyond our solar system were found, astronomers have discovered about 200 of these "extrasolar planets," as they're called.
Where are the other Earths? Answering that question is just the first step in NASA's long-range quest to look for life around stars beyond our solar system, according to Dr. Wesley Traub. And to answer it, he says, we have to go into space.
Grover Swartzlander, an associate professor in The University of Arizona College of Optical Sciences, is developing devices that block out dazzling starlight, allowing astronomers to study planets in nearby solar systems.
Are we alone in the universe? Are there planets like Earth around other "suns" that might harbor life? Thanks to a recent technology breakthrough on a key NASA planet-finding project, the dream of answering those questions is no longer light-years away.
The most detailed measurements to date of the dusty disks around young stars confirm a new theory that the region where rocky planets such as Earth form is much farther away from the star than originally thought. These first definitive measurements of planet-forming zones offer important clues to the initial conditions that give birth to planets.
Looking for biosignatures that would be characteristic of intelligent life is not always about extrapolating the most intelligent things a species might be doing. For instance, would one look for pollutants in the atmosphere? Carnegie Institutions' Maggie Turnbull answers that and other questions from colleagues following her lecture, "Remote Sensing of Life and Habitable Worlds".
Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...
Terrestrial Planet -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...
