Analysis of exploding star's light curve and color spectrum reveal spectacular demise of one of the closest supernova to Earth in recent years; its parent star was so big it's radius was 200 times larger than our sun.
NASA's Fermi Gamma-ray Space Telescope has made a tantalizing discovery associated with the first-ever detection of gravitational waves. A burst of X-ray light may have been the flash produced when two black holes collided.
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.
