How the darkness and the cold killed the dinosaurs Potsdam, Germany (SPX) Jan 17, 2017 66 million years ago, the sudden extinction of the dinosaurs started the ascent of the mammals, ultimately resulting in humankind's reign on Earth. Climate scientists now reconstructed how tiny droplets of sulfuric acid formed high up in the air after the well-known impact of a large asteroid and blocking the sunlight for several years, had a profound influence on life on Earth. Plants died, and death spread through the food web. Previous theories focused on the shorter-lived dust ejected by the i ... read more |

The crew has been selected, and research studies confirmed for the 2017 mission of the University of Hawai?i at Manoa's Hawai?i Space Exploration Analog and Simulation (HI-SEAS). At approximately 3:30 p.m. on January 19, 2017, six astronaut-like crewmembers will enter a geodesic dome atop Mauna Loa on the island of Hawai?i as part of an eight-month research study of human behavior and perf ... more |
The rocket Kuaizhou-1A (KZ-1A) has sent three satellites into space in its first commercial mission on Monday. The rocket, carrying the satellite JL-1 and two CubeSats XY-S1 and Caton-1, blasted off from northwestern China's Jiuquan Satellite Launch Center at around 12:11 p.m. Monday Beijing Time, according to a statement from the center. The KZ-1A was developed from the Kuaizhou-1 r ... more |

Researchers have invented a range of instruments from giant telescopes to rovers to search for life in outer space, but so far, these efforts have yielded no definitive evidence that it exists beyond Earth. Now scientists have developed a new tool that can look for signs of life with 10,000 times more sensitivity than instruments carried on previous spaceflight missions. Their report appears in ... more |
Pluto's relationship with its moon Charon is one of the more unusual interactions in the solar system due to Charon's size and proximity. It's more than half of Pluto's diameter and orbits only 12,000 or so miles away. To put that into perspective, picture our moon three times closer to Earth, and as large as Mars. A new study from the Georgia Institute of Technology provides additional in ... more |

A research team led by scientists at the University of California San Diego have published the first live recording of ruby seadragons. Ruby seadragons are the third species of seadragon to be discovered, first described in 2015. The marine animal is part of the Syngnathidae family, which also includes seahorses. Researchers at UCSD's Scripps Institution of Oceanography published ... more |

A UCLA-led research team reports that the moon is at least 4.51 billion years old, or 40 million to 140 million years older than scientists previously thought. The findings - based on an analysis of minerals from the moon called zircons that were brought back to Earth by the Apollo 14 mission in 1971 - are published Jan. 11 in the journal Science Advances. The moon's age has been a hotly d ... more |

The top 2 inches of topsoil on all of Earth's landmasses contains an infinitesimal fraction of the planet's water - less than one-thousandth of a percent. Yet because of its position at the interface between the land and the atmosphere, that tiny amount plays a crucial role in everything from agriculture to weather and climate, and even the spread of disease. The behavior and dynamics of t ... more |
A groundbreaking new optical device, developed at NJIT's Big Bear Solar Observatory (BBSO) to correct images of the Sun distorted by multiple layers of atmospheric turbulence, is providing scientists with the most precisely detailed, real-time pictures to date of solar activity occurring across vast stretches of the star's surface. The observatory's 1.6-meter New Solar Telescope can now pr ... more |

The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth, well outside the Milky Way's spiral disk. New research by Harvard astronomers shows that half of those stars might have been ripped from another galaxy: the Sagittarius dwarf. Moreover, they are members of a lengthy stream of stars extending one million light-years across space, or 10 times the width of o ... more |
Every few thousand years, an unlucky star wanders too close to the black hole at the center of the Milky Way. The black hole's powerful gravity rips the star apart, sending a long streamer of gas whipping outward. That would seem to be the end of the story, but it's not. New research shows that not only can the gas gather itself into planet-size objects, but those objects then are flung througho ... more |
