ESA Ariel Space Telescope Will Survey Atmospheres of 1000 Exoplanets Starting in 2029

ESA’s exoplanet mission Ariel, scheduled for launch in 2029, has moved from study to implementation phase, following which an industrial contractor will be selected to build the spacecraft. Ariel, the Atmospheric remote-sensing infrared exoplanet large-survey mission, addresses one of the key themes of ESA’s Cosmic Vision programme: What are the conditions for planet formation and …

24 Exoplanets Would Be Better for Supporting Life Than Our Earth

Washington State University researchers have identified 24 top contenders for super habitable exoplanets that would be better at supporting life than the Earth. The exoplanets are all over 100 light-years away. There is now a database of 4500 exoplanets from the ongoing surveys of other stars. Superhabitable exoplanets have the following features: * are in …

Roman Space Telescope AKA WFIRST Field of View 100 Times Hubble

The Nancy Grace Roman Space Telescope (Wide Field Infrared Survey Telescope or WFIRST) is a NASA infrared space observatory that will launch in 2025. The funding for this and all NASA projects is precarious. NASA’s ability to execute on large, multi-year science project has also been less than reliable. Roman uses an existing 2.4-meter wide …

Solar Systems Without a Jupiter Can Have up to Seven Earth-like Planets

Other solar system could have as many as seven Earth-like planets, when those solar systems do not have a gas giant planet like Jupiter. The team created a model system in which they simulated planets of various sizes orbiting their stars. An algorithm accounted for gravitational forces and helped test how the planets interacted with …

Proposed First Gravity Lens Mission by 2028 that Could Spot Large Islands on Exoplanets by 2050

A meter-class telescope with a coronagraph to block solar light, placed in the strong interference region of the solar gravitational lens (SGL), is capable of imaging an exoplanet at a distance of up to 30 parsecs with a few 10 km-scale resolution on its surface. The picture shows results of a simulation of the effects …

Six Billion Earth-Like Planets Around G Type Stars But Red Dwarf Systems Are Not Counted

There may be as many as one Earth-like planet for every five Sun-like stars in the Milky way Galaxy, according to new estimates by University of British Columbia astronomers using data from NASA’s Kepler mission. To be considered Earth-like, a planet must be rocky, roughly Earth-sized and orbiting Sun-like (G-type) stars. It also has to …

35% of exoplanets 5-10 times bigger than Earth are 50% water which is 2500 times the 0.02% of Earth

About 35% of all known exoplanets which are bigger than Earth should be water-rich. These water worlds likely formed in similar ways to the giant planet cores Jupiter, Saturn, Uranus, Neptune in our own solar system. The newly-launched TESS mission will find many more of them, with the help of ground-based spectroscopic follow-up. The next …

New methods confirmed 44 exoplanets including 16 earth sized exoplanets

An international team of astronomers using data from NASA’s Kepler and the European Space Agency (ESA)’s Gaia space telescopes, as well as ground-based telescopes have confirmed 44 exoplanets. New techniques developed to validate the find could hugely accelerate the confirmation of more extrasolar planet candidates. John Livingston, lead author of the study and a graduate …
