Beacons of Life
Observations of potential biosignatures on other worlds are slowly getting within reach. What kind of signal might be among the lowest-hanging fruit?
Can we detect auroral emission from Proxima b?
Here on Earth, and within the solar system, we have become very familiar with star-planet interactions through observations of the dazzling aurora. However we have not been able to observe it on an exoplanet before. Is it too dim? Or are we just limited by instrumentation?
Illusion and reality
The study of exoplanet atmospheres is still a very new field that requires detection of tiny signals. Today’s bite is about a review article that looks back at occasionally illusory results and towards the future.
What do you have to do to get a water covered planet around here?
Applying climate models to Kepler-62f throws light on what configurations might support habitability.
Planet or Noise?
How to find an exoplanet, twice.
A new discovery of a secondary eclipse
HAT-P-11b is a Neptune-size transiting exoplanet with water in its atmosphere. Here we discuss the first detection of its secondary eclipse.
