Water worlds could have incredibly deep oceans, propose new models

Artistic representation of a water world. Image: NASA / JPL-Caltech Scientists have good reason to believe that so-called water worlds – exoplanets covered with surfaces entirely from a single giant ocean – are common in the galaxy. However, new computer simulations suggest that not only water worlds are prevalent, but also that they are bursting with water – and at …

The smallest and farthest worlds ever explored by NASA are really weird

HOUSTON – In recent months, NASA has explored the smallest object ever in orbit and the farthest body ever – and found that both worlds are stranger than anyone would ever have imagined can. The 800-foot-wide asteroid Bennu, which is being investigated by the space probe OSIRIS-REx, produces strange dust clouds. Lead investigator Dante Lauretta, a planetary scientist at the …

TRAPPIST 1's seven intriguing worlds

The small, cool M dwarf star TRAPPIST-1 and its seven worlds. New research from the University of Washington speculates on possible climates of these worlds and how they may have evolved.NASA Not all stars are like the sun. TRAPPIST-1. The work thus could help astronomers more effectively study planets around stars unlike our sun, and better use the limited, experimental …

NASA's Kepler Telescope retires after finding thousands of worlds

NASA's legendary Kepler Space Telescope has withdrawn after exhausting the fuel needed for further scientific operations. This ended a nine-and-a-half-year mission that saw over 2,600 intriguing exoplanets, some of which may be housed. Life, the US Space Agency said. Data collected by Kepler's space missions indicates that our skies are filled with billions of hidden planets – more than the …

Scientists hunting exoplanets have developed a clever new strategy to find migrating worlds that are hidden

Researchers will use data from the ALMA telescope to study migration patterns of exoplanets in distant star systems. A telescope capable of capturing dust rings from faraway star systems could come a long way Practical as scientists have developed a new strategy to help them find hidden worlds and the birthplace of exoplanets in As these rings take place, scientists …

Water worlds could support life: Studying

By: PTI | Washington | Published: September 1, 2018 10:18:47 pm Scientists have hypothesized that planets covered in a deep ocean would not support the mineral cycle and gases that would keep the climate stable on earth and thus not life-friendly. (Source: Pennsylvania State University) The conditions for survival on planets that are completely covered with water are smoother than …
