Nancy Grace Roman Space Telescope →. The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. [9]
Reproduction of an early electron microscope constructed by Ernst Ruska in the 1930s. Many developments laid the groundwork of the electron optics used in microscopes. [2] One significant step was the work of Hertz in 1883 [3] who made a cathode-ray tube with electrostatic and magnetic deflection, demonstrating manipulation of the direction of an electron beam.
The James Webb Space Telescope (JWST) is an international 21st-century space observatory that was launched on 25 December 2021. [1][2] It is intended to be the premier observatory of the 2020s, combining the largest mirror yet on a near-infrared space telescope with a suite of technologically advanced instruments from around the world.
Also known as simply “Webb”, the James Webb Telescope is a space telescope that was launched into space in order to expand scientists’ knowledge of the universe. The telescope follows the ...
IEEE Founders Medal (1981) Scientific career. Institutions. RCA. James Hillier, OC (August 22, 1915 – January 15, 2007) was a Canadian - American scientist and inventor who designed and built, with Albert Prebus, the first successful high-resolution electron microscope in North America in 1938. [1]
James E. Webb. James Edwin Webb (October 7, 1906 – March 27, 1992) was an American government official who served as Undersecretary of State from 1949 to 1952. He was the second Administrator of NASA from February 14, 1961, to October 7, 1968. Webb led NASA from the beginning of the Kennedy administration through the end of the Johnson ...
1936: Erwin Wilhelm Müller invents the field emission microscope. 1938: James Hillier builds another TEM. 1951: Erwin Wilhelm Müller invents the field ion microscope and is the first to see atoms. 1953: Frits Zernike, professor of theoretical physics, receives the Nobel Prize in Physics for his invention of the phase-contrast microscope.
Academic advisors. Watt W. Webb. Winfried Denk (born November 12, 1957, in Munich) is a German physicist. He built the first two-photon microscope while he was a graduate student (and briefly a postdoc) in Watt W. Webb 's lab at Cornell University, in 1989.
