It is theoretically possible that habitable planets exist around pulsars - spinning neutron stars that emit short, quick pulses of radiation. According to new research, such planets must have an enormous atmosphere that converts the deadly x-rays and high energy particles of the pulsar into heat. The results, from astronomers at the University of Cambridge and Leiden University, are reported in the journal Astronomy & Astrophysics.
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 team of astronomers, including researchers from the University of Cambridge, used data gathered by the Kepler Space Telescope to observe and confirm details of the outermost of seven exoplanets orbiting the star TRAPPIST-1.
An international team of astronomers, including researchers from the University of Cambridge, has made the most detailed image of the ring of dusty debris surrounding a young star and found that the ice content of colliding comets within it is similar to comets in our own solar system.
Martin Rees is Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge, the Astronomer Royal, a member of Britain’s House of Lords, and a former President of the Royal Society. The following interview was conducted at Trinity College, Cambridge, by The Conversation’s Matt Warren.
An international team of astronomers has found a system of seven potentially habitable planets orbiting a star 39 light years away three of which could have water on their surfaces raising the possibility they could host life. Using ground and space telescopes, the team identified the planets as they passed in front of the ultracool dwarf star known as TRAPPIST-1. The star is around eight per cent of the mass of the Sun and is no bigger than Jupiter.
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.
Astronomers have found the first evidence of comets around a star similar to the sun, providing an opportunity to study what our solar system was like as a ‘baby’.
Three Earth-sized planets have been discovered orbiting a dim and cool star, and may be the best place to search for life beyond the Solar System.
