The Gamma Ray Sky - February 22nd, 1997.

"What if you could "see" gamma rays? If you could, the sky would seem to be filled with a shimmering high-energy glow from the most exotic and mysterious objects in the Universe. In the early 1990s, NASA's orbiting Compton Observatory produced this premier vista of the entire sky in gamma rays - photons with more than 40 million times the energy of visible light. The diffuse gamma-ray glow from the plane of our Milky Way galaxy runs horizontally through the false-colour image. The brightest spots in the galactic plane (left of the center) are pulsars - spinning magnetised neutron stars formed in the violent crucibles of stellar explosions. Above and below the plane, quasars, believed to be powered by supermassive black holes, produce gamma-ray beacons at the edges of the Universe."

Seeing in Gamma Rays, by Fermi.

The gamma ray map of the sky looks like fascinating, the shape you see is that of our own galaxy, the Milky Way, and as you move in towards the centre, there's a concentration of Pulsars, old dead stars still beaming out gamma radiation, but look closer and you can see a number of objects not in the galactic plane.

Many of these are far off galaxies themselves, but a few don't correspond to any known object, at least currently mapped, and are the subject of much ongoing research.

The History Of Television

Television refers to a system for transmitting visual images and sound that are reproduced on screens, primarily to broadcast programs for entertainment, information, and education. History of Television Early Concepts and Development: 1870s-1900s: The concept of transmitting images wirelessly dates back to the late 19th century. Paul Nipkow’s invention of the Nipkow disk in 1884 was an early…

Figure 20.3 summarises the wavelengths and frequencies of some regions of the electromagnetic spectrum. (...) The infrared region of the electromagnetic spectrum (figure 20.3) covers the range of wavelengths from 7.8 × 10-⁷ m (just longer than the visible than the visible region) to 2.0 × 10-³ m (just shorter than the microwave region).

Gamma Ray Burster - March 19th, 1997.

"Where and what are the Gamma-Ray Bursters? At the time of their discovery in the early 1970s, nobody was able to explain the cause of mysterious flashes of gamma rays that came from seemingly random directions in the sky. Worse yet, it was even unclear whether these high energy explosions originated in our own galaxy, or in distant galaxies across the Universe. Until late February, 1997, these bursters were known only by their gamma-ray flashes - no counterpart had been seen at any other wavelength. But on February 28th, an Italian/Dutch satellite known as BeppoSAX detected what may well have been X-rays from a burster, eight hours after the gamma-ray flash. The discovery image is shown above. Hours later, using the position provided by this X-ray image, ground-based telescopes recovered an even better located variable optical source, which also seemed to be related to the burster. Dramatically, this optical transient has faded now. In its place lies a steady source that appears to be a dim, distant galaxy."
