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.
In 2010 scientists discovered four 'monster' sized stars, with the heaviest more than 300 times as massive as our Sun. Scientists have now found an explanation: the ultramassive stars were created from the merger of lighter stars in tight binary systems.
NASA's most advanced Mars rover Curiosity has landed on the Red Planet. The one-ton rover, hanging by ropes from a rocket backpack, touched down onto Mars Sunday to end a 36-week flight and begin a two-year investigation.
Are we alone? Or was there life on another planet? NASA's $2.5 billion dream machine, the Mars Science Laboratory, aims to take the first steps toward finding out when it nears Mars' surface on Monday. NASA said it will find out if its Mars Science Laboratory and rover, Curiosity - designed to hunt for soil-based signatures of life and send back data to prepare for a future human mission - landed safely at 1:31 am Eastern time on Monday.
A team of researchers at NASA's Johnson Space Center in Houston and Lawrence Berkeley National Laboratory in Berkeley, Calif., has found radiation from protons could further enhance a process that occurs during tumor progression. This information may help lead to better methods to protect astronauts from the harmful effects of radiation in space, as well as help cancer researchers on Earth better understand the effects of radiation treatment on the human body.
