47 Tucanae: A globular cluster located about 15,000 light years from Earth in the constellation of Tucana.
Description: This Chandra image provides the first complete census of compact binary stars in the core of the globular cluster known as 47 Tucanae. As the oldest stellar systems in the Milky Way Galaxy, globular clusters are laboratories for stellar and dynamical evolution. Nearly all objects in the Chandra images are “binary systems,” in which a normal, Sun-like star companion orbits a collapsed star, either a white dwarf or neutron star. The data also reveal the presence of “millisecond pulsars” that rotate extremely rapidly, between 100 to nearly 1000 times a second.
Creator/Photographer: Chandra X-ray Observatory
NASA’s Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. The mirrors on Chandra are the largest, most precisely shaped and aligned, and smoothest mirrors ever constructed. Chandra is helping scientists better understand the hot, turbulent regions of space and answer fundamental questions about origin, evolution, and destiny of the Universe. The images Chandra makes are twenty-five times sharper than the best previous X-ray telescope. NASA’s Marshall Space Flight Center in Huntsville, Ala., manages the Chandra program for NASA’s Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory controls Chandra science and flight operations from the Chandra X-ray Center in Cambridge, Massachusetts.

The Parkes Observatory is a radio telescope observatory, 20 kilometres north of the town of Parkes, New South Wales, Australia. It was one of several radio antennas used to receive images of the Apollo 11 moon landing in July 1969.
CSIRO Parkes radio telescope is the largest and oldest of the eight antennas comprising the ‘Australian Telescope National Facility’. The Compact Array of six 22-metre dishes near Narrabri and another near Coonabarabran link up with the 64 metre Parkes to synthesise a telescope some 300 kilometres across.
Since commissioning in 1961, Parkes Observatory has been responsible for many world firsts in radio astronomy. Highlights include: the identification of the first known Quasar in 1963; mapping of important regions in the galaxy, the Milky Way; participating in the NASA Apollo Moon missions, Voyager II encounter of Neptune in 1989, Mars missions in 2004; ESO’s Giotto Spacecraft encounter of Halleys Comet in 1986; Galileo Spacecraft’s exploration of Jupiter and its moons in 1997; Cassini Huygens mission to Saturn and Titan in 2005; all sky radio surveys of the Southern Skies; Pulsar survey work including the discovery of the first double Pulsar system in 2003; SETI Project Phoenix; and an ongoing search for hidden galaxies.
Parkes Dish – the movie star
The movie “The Dish” was loosely based on Parkes involvement with the Apollo moon landings. Parkes has also starred in television commercials, documentaries and even a Korean romance movie.
Astronomers are baffled by what may be the tail of a spinning neutron star or pulsar named PSR JO357+3205, whose brightest point is well away from the star. Further observations by the Chandra X-ray Observatory and other telescopes are planned. Credit: NASA/CXC/A. Hobart Video Rating: 5 / 5
This recording of the pulsar CP1133 was received on May 9th 1968 at Aricebo Radio Telescope in Puerto Rico. The receiver was tuned to 111.5 MHz with a resolution bandwidth of 300 kHz and a video bandwidth of 3 kHz. This pulsar has a period of 1.1878 seconds. Recording kindly provided by Bob K5DZE.

Radio astronomy as defined is astronomy’s sub field which studies the celestial or ethereal objects which are at the frequency of radio. Radio astronomy means study of radiations with the wavelength more than 1 millimeter approx. In 1930’s radio-waves first detection from object of astronomy was being made, when Jansky saw some radiation that was coming out from Milky-Way. Observations that were made later identified radio-emission’s various sources. Such observations included galaxies and stars along with new object’s classes like radio-galaxies, pulsars, masers and quasars.
Radio astronomy usually is being conducted by the usage of huge radio-antennae which are also called as the radio-telescopes which are being either singularly used or used with many telescopes linked together utilizing radio-interferometry’s as well as aperture-synthesis’ techniques. Usage of
