Star On The Run - SpaceDaily Using ESO's Very Large Telescope, astronomers have recorded a massive star moving at more than 2.6 million kilometres per hour (7,200 miles per hour, or 4,500 miles an hour). Stars are not born with such large velocities. Its position in the sky leads to the suggestion that the star was kicked out from the Large Magellanic Cloud, providing indirect evidence for a massive black hole in the Milky Way's closest neighbour. These results will soon be published in the Astrophysical Journal Letters. The data also revealed the high speed of the star, solving the riddle of its present location: the star did not form in the Milky Way halo, but happens to be there while on its interstellar - or intergalactic - travel. This could imply the existence of a massive black hole inside the Large Magellanic Cloud. Another explanation would require the star to be the result of the merging of two stars. |

South Africa To Unveil Its Flagship "Eye Of Africa Into Space" Telescope - SpaceDaily Left: Fish eye photo of the inside of the SALT telescope. The inauguration of the southern hemisphere's largest telescope Thursday near a small South African town would be a milestone towards realising the country's aim as a "first rate science" country, astronomers said this week. The SALT (Southern African Largest Telescope), to be unveiled by President Thabo Mbeki near the arid Karoo town of Sutherland, will give astronomers a first rate glimpse of distant stars, galaxies and quasars. With a mirror diameter of 11 metres (36 feet) SALT has a maximum resolution of 0.25 arcseconds |

Electrons lose their mass in carbon sheets - PhysicsWeb Left: Graphene Two teams of physicists have discovered previously unseen exotic behaviour in sheets of carbon atoms. The teams have shown that electrons move through the sheets as if they have no rest mass. They have also observed a minimum value of conductivity for the sheets and an unusual form of the quantum Hall effect (Nature 438 197 and 201). In particular they discovered that the electrons in graphene behave like relativistic particles that have no rest mass and travel at about 106 metres per second. Although this is a factor of 300 slower than the speed of light in vacuum, it is still much faster than the speed of electrons in an ordinary conductor. Moreover, the electrons in most conductors can be described by non-relativistic quantum mechanics, whereas the electrons in graphene need to be treated Both teams also observe a new, relativistic, "half-integer" quantum Hall effect. Electrons in graphene behave like relativistic particles that have no rest mass. |
