Title: Are Black Hole Starships Possible Authors: Louis Crane, Shawn Westmoreland We investigate whether it is physically possible to build starships or power sources using the Hawking radiation of an artificial black hole as a power source. The proposal seems to be at the edge of possibility, bu...
An unpopular pigment used by artists in the 18th Century could lead to more energy efficient, faster computers.
Cobalt green, as the dye is known, has been tested by a US team who believe it could be used in "spintronic" devices.
Spintronics involves manipulating the magnetic properties of e...
This weekend a Norfolk high school, one of the only schools in the UK lucky enough to have its own observatory, will be showing off its new deep space telescope at a special astronomy event at the school. The giant 30inch telescope in its own observatory at Reepham High School between Aylsham and Faken...

The Submillimeter Array Astronomers are meeting this week in Cambridge, Mass., to discuss recent advances generated by a new astronomical facility-the Submillimeter Array (SMA) on Mauna Kea, Hawaii. A joint project of the Smithsonian Astrophysical Observatory (SAO) and the Academia Sinica I...
Supernovae mark the explosive deaths of particularly massive stars. During the few weeks it lasts, a supernova can outshine all the other stars in a galaxy combined. As if this wasn't powerful enough, there is a rare type of super-charged supernova called a hypernova. With a power about 100 times th...
