Approximately two million years ago a star exploded in a supernova close to our solar system: Its traces can still be found today in the form of an iron isotope found on the ocean floor. Now scientists have found increased concentrations of this supernova-iron in lunar samples as well.
Understanding the physics of galaxy formation is arguably among the greatest problems in modern astrophysics. A newly formed research group investigates the impact of cosmic rays on galaxy and cluster formation.
Scientists are set to use computer models to investigate the results of experimental testing at NASA's Marshall Space Flight Center in Huntsville to develop an engineering tool to design missions using a new type of long-distance space propulsion.
Deep radio imaging has revealed that supermassive black holes in a region of the distant universe are all spinning out radio jets in the same direction - most likely a result of primordial mass fluctuations in the early universe.
Physicists have developed optical technology for the 'correction' of light coming from distant stars, which will significantly improve the 'seeing' of telescopes and therefore will enable us to directly observe exoplanets as Earth-twins.
Astronomers using an orbiting radio telescope in conjunction with four ground-based radio telescopes have achieved the highest resolution, or ability to discern fine detail, of any astronomical observation ever made. Their achievement produced a pair of scientific surprises that promise to advance the understanding of quasars, supermassive black holes at the cores of galaxies.
Researchers have developed a new conceptual framework for understanding how stars similar to our Sun evolve. Their framework helps explain how the rotation of stars, their emission of x-rays, and the intensity of their stellar winds vary with time.
NASA's planet hunter, the Kepler space telescope, has captured the brilliant flash of an exploding star's shock wave - what astronomers call the 'shock breakout' of a supernova - for the first time in visible light wavelengths.
