Tuomi's team ran statistical analyses to tease out possible planetary signals from background noise.

With entry categories for science / healthcare workers and the under 25s as well as professional and amateur photographers, the competition is an opportunity to stimulate an interest in any area of science, from planetary movements to cellular signalling or more general topics such as physics or the environment, as well as demonstrating artistic flair.

Such radio traffic could be readily apparent On the earth, for example, a new radar system employed with the telescope at the Arecibo Observatory for planetary studies emits a narrow - bandwidth signal that, if it were detected from another star, would be between a million and 10 billion times brighter than the sun at the same frequency.

The effect of stellar contamination is up to 15 times larger than the signal expected from molecules in the atmosphere of a rocky planet (light green band), which means that we can't currently draw any meaningful conclusions about planetary atmospheres from measurements like this.

The expected Doppler signals are too small to confirm them by demonstrating that their masses are in the planetary regi... ▽ More We present an investigation of twelve candidate transiting planets from Kepler with orbital periods ranging from 34 to 207 days, selected from initial indications that they are small and potentially in the habitable zone (HZ) of their parent stars.

We combine the estimate of Teff and [Fe / H] with an estimate o... ▽ More We present the discovery of the Kepler - 19 planetary system, which we first identified from a 9.3 - day periodic transit signal in the Kepler photometry.

Abstract: We present the discovery of the Kepler - 19 planetary system, which we first identified from a 9.3 - day periodic transit signal in the Kepler photometry.

We apply a statistical method to show that the likelihood of the planetary interpretation of the transit signals is more than three orders of magnitude larger than that of the alternative hypothesis that the signals result from an eclipsing binary star.

Using BLENDER together with constraints from other follow - up observations we are able to rule out all blends for the two deeper signals, and provide independent validation of their planetary nature.

The final image, a deeper tone of black, is the result of stacking cleaned - up exposures to reveal a clear signal from the planetary system.

These include using the same model used to detect the planet instead to fit synthetic, planet - free data (with realistic covariance properties, and time sampling identical to the real data), and checking whether the «planet» is still detected; comparing the strength of the planetary signal with similar Keplerian signals injected into the original observations; performing Bayesian model comparisons between planet and no - planet models; and checking how robust the planetary signal is to datapoints being removed from the observations.

The Planetary Society is the only organization now that does optical searches, so we have a telescope that looks, if you will, for laser signals from other civilizations, and you might say that sounds crazy.

This is because part of the outgoing radiation signal (albeit small) is emerging from relatively warm layers aloft, and thus slightly less emission is demanded from the troposphere in order to satisfy planetary energy balance.

Given that hindcasts giving such detail can be made back several hundred years from the heliocentric planetary ordering of the daily - weekly solar signal, such NAO / AO based forecasts can be produced for any useful range.

Three - dimensional (3D) planetary general circulation models (GCMs) derived from the models that we use to project 21st Century changes in Earth's climate can now be used to address outstanding questions about how Earth became and remained habitable despite wide swings in solar radiation, atmospheric chemistry, and other climate forcings; whether these different eras of habitability manifest themselves in signals that might be detected from a great distance; whether and how planets such as Mars and Venus were habitable in the past; how common habitable exoplanets might be; and how we might best answer this question with future observations.
