Hubble observations used to answer key exoplanet questions

Archival observations of 25 hot Jupiters by the NASA/ESA Hubble Space Telescope have been analysed by an international team of astronomers, enabling them to answer five open questions important to our understanding of exoplanet atmospheres. Amongst other findings, the team found that the presence of metal oxides and hydrides in the hottest exoplanet atmospheres was […]

Tonight, BepiColombo will perform the first of six Mercury flybys, each honing the spacecrafts’ trajectory with the ultimate goal of shedding enough energy – after its two years ‘falling’ towards the Sun – to be caught by the innermost planet’s gravity and remain in Mercurial orbit. This first Mercury flyby will alter the spacecraft’s velocity by 2.1 km/s […]
