In the quest to understand how the world's weather moves around the globe, scientists have had to tease apart different kinds of atmospheric movement, such as the great jet streams that can move across a whole hemisphere versus more intricate, localized flows. Much the same must currently be done to understand the various motions at work in the great space weather system that links the sun and Earth as the sun shoots material out in all directions, creating its own version of a particle sea to fill up the solar system.
Astronomers using data from NASA's Hubble Space Telescope have caught two clusters full of massive stars that may be in the early stages of merging. The clusters are 170,000 light-years away in the Large Magellanic Cloud, a small satellite galaxy to our Milky Way.
An international team, led by EXOEarths researchers (Centro de Astrofísica da Universidade do Porto - CAUP), proposes that metals like Magnesium might have an important role in the formation of low mass planets.
NASA has selected a team led by Ball Aerospace & Technologies Corporation of Boulder, Colo., for a technology demonstration of a high performance "green" propellant alternative to the highly toxic fuel hydrazine. With this award, NASA opens a new era of innovative and non-toxic green fuels that are less harmful to our environment, have fewer operational hazards, and decrease the complexity and cost of launch processing.
Astronomers have found an extraordinary galaxy cluster, one of the largest objects in the universe, that is breaking several important cosmic records. Observations of the Phoenix cluster with NASA's Chandra X-ray Observatory, the National Science Foundation's South Pole Telescope, and eight other world-class observatories may force astronomers to rethink how these colossal structures and the galaxies that inhabit them evolve.
Last spring private industry successfully sent a spacecraft carrying cargo to the International Space Station. Now the race is on to see which company will be the first to make commercial human spaceflight a reality.
Scientists at the Harvard-Smithsonian Center for Astrophysics (CfA) and their colleagues at the Heidelberg Institute for Theoretical Studies (HITS) have invented a new computational approach that can accurately follow the birth and evolution of thousands of galaxies over billions of years. For the first time it is now possible to build a universe from scratch that brims with galaxies like we observe around us.
Researchers may have discovered a new method to predict solar flares more than a day before they occur, providing advance warning to help protect satellites, power grids and astronauts from potentially dangerous radiation.
Gamma-ray photons seen emanating from the center of the Milky Way galaxy are consistent with the intriguing possibility that dark-matter particles are annihilating each other in space, according to research by UC Irvine astrophysicists.
When Curiosity touched down safely on Mars on August 5, John Grotzinger, the mission's chief scientist and the Fletcher Jones Professor of Geology at Caltech, was given the 'keys' to the car-sized rover.
NASA has chosen three teams to advance the state of the art for small spacecraft in the areas of communications, formation flying and docking systems. The cutting-edge space technology flights are expected to take place in 2014 and 2015.
The first images from Curiosity's color Mast Camera, or Mastcam, have been received by scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The 130 low-resolution thumbnails, which were received Thursday morning, provide scientists and engineers of NASA's newest Mars rover their first color, horizon-to-horizon glimpse of Gale Crater.
An international team of researchers used a state-of-the-art simulation of the Milky Way to test their mass-measuring method before applying it to real data. This threw up a number of surprises: they noticed that standard techniques used over the past twenty years were biased, always tending to underestimate the amount of dark matter.
Astronomers have constructed the largest-ever three-dimensional map of massive galaxies and distant black holes, which will help the investigation of the mysterious "dark matter" and "dark energy" that make up 96 percent of the universe.
The aircraft, designed by The Boeing Co. and built by Cranfield Aerospace Limited of the United Kingdom, is flying again in partnership with NASA. The new X-48C model, which was formerly the X-48B Blended Wing Body aircraft, was modified to evaluate the low-speed stability and control of a low-noise version of a notional, future Hybrid Wing Body aircraft design.
