Does looking up into a starry night make you think of Star Wars, with beings from other galaxies flying around at the speed of light, shooting at one another? People can look up at the stars all their lives and never really be sure what's out there. "Back in 1949 when I was a kid, I made a 2-inch telescope," Andy Keefer says, referring to the diameter of the...

Maximilian Franz Joseph Cornelius Wolf (June 21, 1863 - October 3, 1932) was a German astronomer and pioneer of astrophotography. He is accredited with the discovery of a large quantity of asteroids. Heidelberg, Germany was his birthplace. He received his PhD at the University of Heidelberg in 1888, and in 1890 he took employment in that institution. Beginning in 1891, Wolf discovered more than 200 asteroids with the Bruce double-astrograph, while working at the Landessternwarte...

Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....

  • 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.
