An international team of astronomers has detected titanium oxide in the atmosphere of an exoplanet for the first time. The results, reported in the journal Nature, provide unique information about the chemical composition and the temperature and pressure structure of the atmosphere of this unusual and very hot world.
An international exoplanet ‘think tank’ is meeting this week in Cambridge to deliberate on the ten most important questions that humanity could answer in the next decade about planets outside our solar system.
Nikku Madhusudhan (Institute of Astronomy) has been given the Bappu Gold Medal for contributions to astronomy and astrophysics by a young scientist.
Astronomers have discovered a disc of planetary debris surrounding a young sun-like star that shares remarkable similarities with the Kuiper Belt that lies beyond Neptune, and may aid in understanding how our solar system developed.
Astronomers have detected wildly changing temperatures on a super Earth – the first time any atmospheric variability has been observed on a rocky planet outside the solar system – and believe it could be due to huge amounts of volcanic activity, further adding to the mystery of what had been nicknamed the ‘diamond planet’.
The discovery of water vapour in the atmospheres of three exoplanets includes the most precise measurement of any chemical in a planet outside the solar system, and has major implications for planet formation and the search for water on Earth-like habitable exoplanets in future.
