astronomy35% 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 …

astronomyNew 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 …

exoplanetsNASA and Spacex target launching TESS planet hunting telescope within 9 hours

NASA and SpaceX are targeting the launch of NASA’s Transiting Exoplanet Survey Satellite, or TESS, on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station for no earlier than 6:51 p.m. EDT. Frequent updates …

astronomyIn Mid-April NASA will launch next generation planet hunting space telescope

NASA’s next planet hunter, the Transiting Exoplanet Survey Satellite (TESS), is scheduled to launch as early as April 16, 2018. TESS is expected to find thousands of planets outside our solar system, known as exoplanets, orbiting the nearest and brightest …

astronomyNanohmics -using stellar echos to find exoplanets

When a star has a solar the light will bounce off of any exoplanets. This could then be detected by fast sensor telescopes. Any fluctuation in the star and not just solar flares can be used in this method. A …

astronomyPossible Exomoon discovery

The high-profile quest to spot moons orbiting distant planets has been a series of let-downs, with each hint of an ‘exomoon’ fading under closer inspection. So astronomer David Kipping, at Columbia University in New York City, didn’t want to reveal …

exoplanetsNew class of exoplanets found

Nearly 3,500 exoplanets have been confirmed so far. In a new Caltech-led study, researchers have classified these planets in much the same way that biologists identify new animal species and have learned that the majority of exoplanets found to date …

astronomyBy 2020 hundreds of earth sized exoplanets should be discovered and many will have basic atmosphere elements detected

Currently there are 3486 confirmed exoplanets (mainly from the Kepler Space telescope survey) and there are 4496 exoplanet candidates and 581 multiplanet systems. We are within about 11 months of the launch of the TESS space telescope. The Transiting Exoplanet …

astronomyHabitable Zone Waterworlds would usually have no land or very little land

A paper suggests that habitable zone waterworlds like Earth would usually have no land or very little land. This would be another factor that would make technological civilizations more rare. On a purely statistical basis, one naïvely expects to find …

astronomy14000+ volunteers helped find new 4 exoplanet solar system

Zooniverse volunteers on Exoplanet Explorers have discovered a new 4-planet system. This new planetary system, 597 light years away in the constellation Aquarius, has dips from four different planets. The planets take only 3 to 13 Earth days to orbit …
