This work is part of an ongoing project which aims to detect terrestrial planets in our neighbouring star system α Centauri using the Doppler method.
A team of astronomers has made the most precise measurements yet of water vapour in the atmospheres of Jupiter-like planets beyond our Solar System and found them to be much drier worlds than expected.
Genomics and Cell Biology
Parts of the primordial soup in which life arose have been maintained in our cells today according to scientists at the University of East Anglia.
The recent discoveries of terrestrial exoplanets and super Earths extending over a broad range of orbital and physical parameters suggests that these planets will span a wide range of climatic regimes.
The core accretion theory for giant planet formation predicts enrichment of elemental abundances in planetary envelopes caused by runaway accretion of planetesimals, which is consistent with measured super-solar abundances of C, N, P, S, Xe, and Ar in Jupiter's atmosphere.
Biosignatures & Paleobiology
Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist if replenished by life.
One of the primary goals of exoplanet science is to find and characterize habitable planets, and direct imaging will play a key role in this effort.
New research published today in the journal Astrobiology shows the vital role of oceans in moderating climate on Earth-like planets.
We present the results of our Hubble Space Telescope program and describe how our image analysis methods were used to re-evaluate the habitability of some of the most interesting Kepler planet candidates.
Here we discuss one of the current reservoirs of water on Mars, the regolith and rocks exposed at the surface.
The M dwarf Gliese 581 is believed to host four planets, including one (GJ 581d) near the habitable zone that could possibly support liquid water on its surface if it is a rocky planet.
