A layer deep in the solar atmosphere can be used to estimate the speed of the solar wind, a stream of electrified gas that constantly blows from the Sun. Estimating the speed of the solar wind will improve space weather fore...

There's been continual speculation about the connection between the Earth's climate and the local Galactic environment, along with the implications for life. Two researchers have explored any such link in more quantitative detail than in the past. Ice Age Epochs and the Sun's Path throu...

Title: Nemesis Reconsidered Authors: Adrian L. Melott (University of Kansas), Richard K. Bambach (Smithsonian Institution Museum of Natural History) The hypothesis of a companion object (Nemesis) orbiting the Sun was motivated by the claim of a terrestrial extinction periodicity, thought t...

Using visible and infrared data collected from telescopes on Hawaii`s Mauna Kea, a team of scientists, led by the University of Maryland's Jessica Sunshine, have identified three asteroids that appear to be among our Solar System's oldest objects. Evidence indicates that these ancient asteroi...

Title: Hysteresis in a Solar Activity Cycle Authors: Vinita Suyal, Awadhesh Prasad, Harinder P. Singh We analyse in situ measurements of solar wind velocity obtained by the Advanced Composition Explorer (ACE) spacecraft during the solar activity cycle 23. We calculated a robust complexity mea...

New images reveal never-before-seen structures of the solar wind as it travels toward and impacts Earth Using data collected by NASA's STEREO spacecraft, researchers at Southwest Research Institute and the National Solar Observatory have developed the first detailed images of solar wind stru...
