Small Exoplanets Come in Two Sizes: Rocky ‘Earths’ and Mini-Neptunes
Astronomers have classified extrasolar planets in the same way that biologists identify new species and have learned that the majority of planets found to date fall into two distinct size classes: rocky, Earth-size planets and gaseous planets smaller than Neptune. “We like to think of this study as classifying planets in the same way that [...]
Ten near-Earth size planets in habitable zone of their star
NASA's Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new planet candidates, 10 of which are near-Earth size and orbiting in their star's habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet.
Deployment of the Space Station's Roll Out Solar Array Experiment
Over the weekend of June 17-18, engineers on the ground remotely operated the International Space Station's Canadarm2 to extract the Roll Out Solar Array experiment from the SpaceX Dragon resupply ship. The experiment will remain attached to the Canadarm2 over seven days to test this advanced, flexible array that rolls out like a tape measure.
A unique data center for cosmological simulations
Scientists have established 'Cosmowebportal', a unique data center for cosmological simulations. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
