  Greenbelt MD (SPX) Dec 20, 2016 A new statistical study of planets found by a technique called gravitational microlensing suggests that Neptune-mass worlds are likely the most common type of planet to form in the icy outer realms of planetary systems. The study provides the first indication of the types of planets waiting to be found far from a host star, where scientists suspect planets form most efficiently. "We've found the apparent sweet spot in the sizes of cold planets. Contrary to some theoretical predictions, we infer fr ... read more |

An international team of scientists, including researchers from the University of Chicago, has made the rare discovery of a planetary system with a host star similar to Earth's sun. Especially intriguing is the star's unusual composition, which indicates it ingested some of its planets.

A major challenge in the exploration of Mars by robots is its uneven surface, which is marked by trenches and craters. Whether the systems can withstand the rough terrain on the Red Planet, they have to prove it on the earth first - for example, in the rocky deserts of the American state of Utah.

The sonic boom created by an airplane comes from the craft's large, speeding body crashing into molecules in the air. But if you shrank the plane to the size of a molecule, would it still generate a shock wave?
Scientists such as University of Iowa physicist Jasper Halekas hope to answer that question by studying miniature shock waves on the moon. These sonic boomlets, physicists believe, ... more India Inc joins hands to bid for moon mission TeamIndus signs contract with ISRO for lunar mission Moonwalker Buzz Aldrin stable after South Pole health scare |

When astronomers and astrophysicists observe flashes of light in the dark sky, they assume they have seen a supernova. Possibly a star has burnt up its supply of nuclear fuel and collapsed, throwing off its outer layers into space; or maybe a dense white dwarf siphoned off material from a companion star until it exploded from excess weight. But a flash of light observed on June 14, 2015 did not ... more Newly formed stars shoot out powerful whirlwinds Young, thin and hyperactive: That's what outlier galaxies look like A new light on stellar death |

The Earth's critical zone isn't called critical for nothing. Known as our planet's outer skin, it is essential for human survival. The critical zone extends from the top of the tallest tree down through the soil and into the water and rock beneath it. It stops at what's called the weathering zone - or where soils first begin to develop.
This zone allows crops to grow well and supports our ... more Eye-Popping View of CO2, Critical Step for Carbon-Cycle Science Revolutions in understanding the ionosphere, Earth's interface to space Researchers dial in to 'thermostat' in Earth's upper atmosphere |

At first glance, Ceres, the largest body in the main asteroid belt, may not look icy. Images from NASA's Dawn spacecraft have revealed a dark, heavily cratered world whose brightest area is made of highly reflective salts - not ice.

Without a doubt, the seahorse belongs to Darwin's "endless forms most beautiful". Its body form is one of a kind. It has neither a tail nor pelvic fin, it swims vertically, bony plates reinforce its entire body and it has no teeth, a rare feature in fish. Another peculiarity is that male seahorses are the ones to become pregnant.
