Nearest bright 'hypervelocity star' found

Astronomers discovered a 'hypervelocity star' that is the closest, second-brightest and among the largest of 20 found so far. Speeding at more than 1 million mph, the star may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious 'dark matter' surrounding the galaxy.

Planck reveals magnetic fingerprint of our galaxy

An international team of astrophysicists has released an unprecedented map of the entire sky that charts the magnetic field shaping our Milky Way Galaxy. The map reveals magnetic field lines running parallel to the plane of the Galaxy, as well as great loops and whorls associated with nearby clouds of gas and dust.

Are we ready for contact with extraterrestrial intelligence?

The SETI project scientists are known for tracking possible extraterrestrial signals, but now they are also considering sending messages from Earth telling of our position. A researcher questions this idea in view of the results from a survey taken by students, revealing the general level of ignorance about the cosmos and the influence of religion when tackling these matters.

Spectrum of gamma-ray burst's afterglow indicates the beginning of the re-ionization process

Researchers discovered an indicator of when re-ionization of the primordial Universe began. Direct measurement of the absorption features in the spectrum of the afterglow toward GRB 130606A, located at a great distance, revealed the proportion of neutral hydrogen gas absorbing the light in its vicinity. This finding provides the best estimate of the amount of such neutral gas in the early Universe.

Entire star cluster thrown out of its galaxy

The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time.

How do we clean up the junkyard orbiting Earth?

The biggest-sized junkyard in the world orbits it, and a University of Alabama in Huntsville aerospace systems engineering graduate student says it's time to get active about reducing the debris field before we reach a tipping point beyond which we may not be able to do much.

Making light work of orbit and attitude control

Microsatellites have to be very light - every gram counts. The same applies to the gyroscopes used to sense the satellite's orientation when in orbit. A novel prototype is seven times lighter and significantly smaller than earlier systems.
