MALAGA, Spain (AP) — Germany was invited to make up the numbers at the inaugural Spain Sevens and went beyond its brief by drawing with Australia 12-12 on Friday. After a scoreless first half, Australia went ahead twice thanks to Nathan Lawson tries, only for Germany to draw at the death after a Tim Lichtenberg try from his own break was drop converted by Fabian Heimpel.

Sing The various methods used over the last 25 years to discover exoplanets and the science of categorizing the many types of exoplanets that have been found was the focus of an April 19 workshop for science writers sponsored by the Space Telescope Science Institute ( STScI virtual symposium cente...
A new theory that may explain why the inner solar system is so different to the outer regions runs counter to the prevailing wisdom. Mercury, Venus, Earth, and Mars in the inner solar system are relatively small, dry planets, unlike Jupiter, Saturn, Uranus, and Neptune in the outer regions, planets that contain much greater quantities of volatile elements. “In the last few years, we’ve also discovered another major difference between the two parts of the solar system,” says Maria Schönbächler, professor at the Institute of Geochemistry and Petrology at ETH Zurich. “Meteorites have a...
Separate formation waves explain differences in inner and outer solar systems Using computer simulations, researchers found that the two solar systems formed in two separate waves that explain why terrestrial planets are small and rocky compared to the ice and gas giants of the outer system. All Rights Reserved. Copyright Mark A. Garlick An international research team including experts based in Zurich have suggested a new theory for planet formation and how differences in the chemical composition of planets and meteorites came about.

Two-step formation explains our solar system's dichotomy of planets By (0) Inner terrestrial protoplanets accrete early, and inherit a substantial amount of radioactive 26Al -- which researchers say explains the difference between smaller, dryer inner solar system planets and larger, wetter outer ones. Photo by Mark A Garlick Jan. 21 (UPI) -- The solar system features a unique dichotomy of planets -- the inner solar system features smaller, drier bodies, while the planets found in the outer solar system are larger and wetter. According to a study published Thursday in the journal Science, t...
