Reports on the discovery of a fluctuating source of radio waves that could be close to the center of the galaxy. Outlook for it to reveal new information about the Milky Way's core; Use of the Very Large Array (VLA) radio telescope near Socorro, New Mexico; Intensity of radio emissions;...
CANBERRA, June 28 (Xinhua) -- Researchers from Australia’s peak scientific agency have determined the location of a one-off burst of powerful cosmic radio waves in a world-first. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) on Friday revealed that it made the discovery...
a summary of the physical and chemical nature of life must begin, not on the earth, but in the sun; in fact, at the suns very center. it is here that is to be found the source of the energy that the sun constantly pours out into space as light and heat. this energy is liberated...
Measurements have been made over a range of frequencies from 38 to 500 Mc/s of the flux density of radio waves from the intense source in Sagittarius. Aerials with high resolving power in the East-West direction were used, giving a strip distribution of brightness across the source. It was...
of hydrogen be converted into helium in the Sun every second. This the Sun has been doing for several thousands of millions of years. The nuclear energy is released at the Sun's center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of ...
英语翻译The vacuum tube,invented near the beginning of our century,gave us the use of radio waves,an energy source never before captured,and later opened the road for television.
Radio source, in astronomy, any of various objects in the universe that emit relatively large amounts of radio waves. Nearly all types of astronomical objects give off some radio radiation, but the strongest sources of such emissions include pulsars, cer

The discovery ofpulsarsin 1967 provided the first evidence of the existence of neutron stars. Pulsars are neutron stars thatemitpulses of radiation once per rotation. The radiation emitted is usuallyradiowaves, but pulsars are also known to emit in optical,X-ray, andgamma-raywavelengths. The ver...
