Prospects for detection of protoplanets
... in the vicinity of the planet only if the object is at a distance of not more than about 100 pc. For larger distances, the contrast between the planetary region and the adjacent disk in all of the considered planet/star/disk configurations will be too low to be detectable. ...

Atmospheric biomarkers on terrestrial exoplanets Abstract Introduction
... have been detected around 107 main sequence stars1 . As the detection of a planet requires observations made over a time comparable to its period, most of them have a short period. The radial velocity method has recently been used successfully to reveal outer planets at the same orbital distance as ...

... These exoplanets are very far away, so how do we actually “see” them? Exoplanets are nearly impossible to photograph in the traditional sense, so we have to find them by observing the effects they have on their parent stars. These effects, driven by gravity and line-of-sight, are visible to us as ei ...

The Stability of Exomoons in the Habitable Zone
... In the investigation into the habitability of extrasolar objects, the main focus has long been on exoplanets, while exomoons have only been considered properly during the last few years. A reason for this is the obvious difficulty in detecting objects that do not primarily orbit a star, but rather a ...

Understanding habitability and using that knowledge to locate the nearest habitable planet may be crucial for our survival as a species.
