The finding sheds light on some universal mysteries, including the possibility that exploding stars created some of the matter that makes up our bodies. Not all explosions are created equal "“ it's as true for film effects as it is for stars. An international team of scientists, including a University of Arizona astronomer, has identified a third type of exploding star, or supernova. Until now, scientists had only observed two kinds of supernovae "“ either hot, young giants that...

A giant laser -- the size of three football fields -- is being used by scientists at a government lab in California to possibly set off a nuclear reaction so intense that it will make a star bloom on the surface of the Earth, according to a recent CNN report. The scientists at the Lawrence Livermore National Laboratory want to create a sun on the ground that seems like a science fiction fantasy straight from Hollywood. But the experiment is for real, and the National Ignition Facility will...

A potential new energy source so controversial that people once regarded it as junk science is moving closer to acceptance by the mainstream scientific community. That's the conclusion of the organizer of one of the largest scientific sessions on the topic "” "cold fusion" "” being held here for the next two days in the Moscone Center during the 239th National Meeting of the American Chemical Society (ACS). "Years ago, many scientists were afraid to speak about 'cold fusion' to a...

OAKLAND, Calif., March 12 /PRNewswire/ -- A major intellectual property jury trial, involving the theft of trade secret information and the breach of Non-Disclosure Agreement (NDA), is set to start on Monday, March 15, 2010. The trial is in Hayward, California, Department 512, Judge John True, III. Plaintiff Victor Kley, who is the sole owner of General Nanotechnology and Metadigm (the other plaintiffs), approached Lawrence Livermore Lab in the Spring of 2004 with a unique idea to assist...

A new experiment that reproduces the magnetic fields of the Earth and other planets has yielded its first significant results. The findings confirm that its unique approach has some potential to be developed as a new way of creating a power-producing plant based on nuclear fusion "” the process that generates the sun's prodigious output of energy. Fusion has been a cherished goal of physicists and energy researchers for more than 50 years. That's because it offers the possibility of...

A massive old star is about to die a spectacular death. As its nuclear fuel runs out, it begins to collapse under its own tremendous weight. The crushing pressure inside the star skyrockets, triggering new nuclear reactions, setting the stage for a terrifying blast. And then... nothing happens. At least that's what supercomputers have been telling astrophysicists for decades. Many of the best computer models of supernova explosions fail to produce an explosion. Instead, according to the...

Dying, for stars, has just gotten more complicated. For some stellar objects, the final phase before or instead of collapsing into a black hole may be what a group of physicists is calling an electroweak star. Glenn Starkman, a professor of physics at Case Western Reserve University, together with former graduate students and post-docs De-Chang Dai and Dejan Stojkovic, now at the State University of New York in Buffalo, and Arthur Lue, at MIT's Lincoln Lab, offer a description of the...

A new class of supernova was discovered by scientists at Berkeley and may be the first example of a new type of exploding star. A team of astrophysicists at UC Santa Barbara had predicted this kind of explosion in their theoretical work. Lars Bildsten, professor at UCSB's Kavli Institute for Theoretical Physics (KITP), and colleagues, predicted a new type of supernova in distant galaxies that would be fainter than most and would rise and fall in brightness in only a few weeks. The discovery,...

Experiments in RFP fusion device show higher currents lead to self-organized helical plasma If you keep twisting a straight elastic string, at some moment it starts kinking in a wild way. Something similar occurs when one increases the electrical current flowing in a magnetized plasma doughnut: it takes on a wild helical shape, which spoils its performance. This phenomenon concerns scientists exploring fusion power, who use powerful magnetic fields to confine plasma during their experiments....

Progress in advanced operational scenarios for tokamak fusion devices provides hope for steady-state fusion power plants In the quest to produce nuclear fusion energy, researchers from the DIII-D National Fusion Facility have recently confirmed long-standing theoretical predictions that performance, efficiency and reliability are simultaneously obtained in tokamaks, the leading magnetic confinement fusion device, operating at their performance limits. Experiments designed to test these...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
