James Blake, a postgraduate student in the 糖心TV Astronomy & Astrophysics Group, gives an overview of his summer project researching the topic of panspermia and applying the theory to the exciting TRAPPIST-1 planetary system.

Dimitri Veras leads an interdisciplinary team of astronomers and biologists in a study exploring the dynamical and biological constraints of interplanetary panspermia. This is the theory that life can hop from planet to planet via some mechanism, most likely aboard asteroids or comets.

CEH member James Jackman leads a recent study of flares in G-type stars, as observed using NGTS. The study shows that G-stars can have flares many times the energy of the Carrington event, and the primary detection is one of the largest amplitude superflares detected from a bright G star.

CEH member David Armstrong has published a new study on automatic vetting of exoplanet candidates using machine learning techniques. In this work he applies it to candidates from NGTS, but the technique is extendable to other transiting exoplanet surveys.
