Fermi Telescope Turns to Dark Matter Search
2013-01-21 10:58:25

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online For much of the last century, scientists have been searching for a mysterious substance thought to make up about 85 percent of the total mass of the Universe. Without it, galactic rotation curves, galaxy interactions and the very structure of the Universe are inconsistent with our knowledge of physics. Yet, this so-called dark matter remains elusive. One reason researchers have had such a difficult time finding and...

Spacetime Is Smooth, Not Foamy

April Flowers for redOrbit.com - Your Universe Online Scientists have long believed that spacetime is foamy, like a freshly pulled draft beer, but new information from an intergalactic photo finish shows it might just be as smooth as a single malt whiskey, instead. Robert Nemiroff, a physicist at Michigan Technological University, reached this conclusion after studying the tracings of three photons of differing wavelengths that had been recorded by NASA's Fermi Gamma-ray Space Telescope...

Lee Rannals for redOrbit.com NASA said that its Fermi Gamma-ray Space Telescope detected the highest-energy light ever associated with an eruption on the sun on March 7. The latest discovery, according to the space agency, is echoing in Fermi's new role as a solar observatory, which is a tool that is being used to understand solar outbursts. The March 7 flare was a class X5.4, and is the strongest eruption so far observed by Fermi's Large Area Telescope (LAT). "For most of Fermi's...

Dwarf Galaxies Observations Provide New Insights On Dark Matter

[ Watch the Video ] There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. Yet, despite decades of effort, no one knows what this "dark matter" really is. Many scientists think it's likely that the mystery will be solved with the discovery of new kinds of subatomic particles, types...

Fermi Eyes 'Crazy-energetic Photons'
2012-03-19 03:40:04

[ Watch the Video ] The human eye is crucial to astronomy. Without the ability to see, the luminous universe of stars, planets and galaxies would be closed to us, unknown forever. Nevertheless, astronomers cannot shake their fascination with the invisible. Outside the realm of human vision is an entire electromagnetic spectrum of wonders. Each type of light--­from radio waves to gamma-rays--reveals something unique about the universe. Some wavelengths are best for studying black...

Image 1 - Fermi Explores New Energy Extremes
2012-01-11 04:12:57

After more than three years in space, NASA's Fermi Gamma-ray Space Telescope is extending its view of the high-energy sky into a largely unexplored electromagnetic range. On Tuesday, the Fermi team announced its first census of energy sources in this new realm. Fermi's Large Area Telescope (LAT) scans the entire sky every three hours, continually deepening its portrait of the sky in gamma rays, the most energetic form of light. While the energy of visible light falls between about 2 and 3...


Word of the Day
tesla
  • 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.
