Image 1 - Gravitational Lens Reveals Details Of Distant, Ancient Galaxy
2012-03-09 03:01:37

Thanks to the presence of a natural “zoom lens” in space, University of Chicago scientists working with NASA´s Hubble Space Telescope have obtained a uniquely close-up look at the brightest gravitationally magnified galaxy yet discovered. The imagery offers a visually striking example of gravitational lensing, in which one massive object´s gravitational field can magnify and distort the light coming from another object behind it. Such optical tricks stem from...


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.
