Crucially, Kepler also detected a slight dip in luminosity, much less dramatic than the dimming associated with the planet passing in front of the star, when HAT - P - 7 b passed behind its star — the spacecraft was seeing only the star's light, without the reflection and glow from the exoplanet.

Now, graduate students at the University of Washington have found a way to detect volcanic activity in the atmospheres of exoplanets, or those outside our solar system, when they transit, or pass in front of their host stars.

By comparing the spectrum of light passing through an exoplanet's atmosphere with that of the unfiltered light emitted by its parent star, astronomers can identify substances present in the exoplanet's air.

PLATO will search for exoplanets using what is known as the transit method, which simply involves measuring the dimming of the light from a star as a planet passes in front of it.

Many of the techniques now used to detect exoplanets — such as observations of their gravitational effect on the movements of their parent stars, or mini-eclipses that occur regularly as they pass in front of the stars as seen from Earth — aren't sensitive enough to detect the presence of an exomoon.

Scientists probably couldn't tell the difference between the light passing through the atmosphere of a distant exoplanet that hosts life (at left in this artist's representation) and the combined light filtered throu

As this light passes through the exoplanet's atmosphere, some of it is absorbed by atmospheric molecules.

This graphic depicts HD 189733b, the first exoplanet caught passing in front of its parent star in X-rays.

Kepler identifies exoplanets by staring at a large number of stars for extended periods and waiting for their brightness to dip periodically when a planet passes in front of them.

Of the more than 300 other known exoplanets, all have been detected indirectly by their effects on their parent stars — either a wobble in induced by the object's orbit or a decrease in detected light from the star as the planet passes in front of it.

It will observe how exoplanets in other solar systems pass in front of their host star - and assist in the search of potentially habitable planets.

The telescope detected these exoplanets through watching for stars dimming as planets pass in front of them.

But if it passes NASA approval, the potential new mission, called K2, could mean a whole different kind of search to find Earth - size exoplanets, along with supernovae, protostars and galaxy clusters.
